# Working with .asf.yaml
`.asf.yaml` is a branch-specific <a href="https://en.wikipedia.org/wiki/YAML" target="_blank">YAML</a> configuration file that a project may create (using a text editor of your choice) and put in the root of a Git repository to control features such as
- notification schemes
- website staging
- GitHub settings
- Pelican builds
It operates on a per-branch basis, meaning you can have different settings for different branches, and only those with an active `.asf.yaml` file will kick off a feature. Metadata settings (repo settings, features, labels) are not branch-dependent and should exist in the main (default) branch.
<h2 id="top">Before you start using .asf.yaml</h2>
- `.asf.yaml` only works with Git repositories. There is no equivalent at the moment for Subversion repositories.
- The configuration file is specific to the branch in which it resides and only code blocks with a `whoami` matching the branch name will run.
- The configuration file holds a great deal of power, as it controls a host of automated systems.
- Before using a feature in `.asf.yaml`, make sure that you have discussed what you propose with the entire project team, and understand what the configuration changes will do to the team's workflow and project resources.
- You can add configuration blocks to an `.asf.yaml` file in any order; they do not depend on each other or flow from one to the next.

<h2 id="project">Project metadata</h2>
Projects can define their data in .asf.yaml, similar to that defined in a <a href="https://projects.apache.org/doap.html">DOAP file</a>, but in a way that can be synchronized with Apache Trusted Releases (ATR)
<h3 id="project-definition">Schema</h3>
Most of the field names under `metadata` are either identical to those in DOAP or are self explanatory. Below is an example using the ATR project data:
`key` (the ATR project key) and `committee` (its owning committee) are both required. The `committee` must match the start of your repository name — for example a repository named `tooling-trusted-releases` must belong to the `tooling` committee.
`name` is the project's full display name in ATR and must start with `Apache ` (including the space), for example `Apache Maven Filtering`. Synchronization does not add this prefix automatically. A name must be supplied when creating a project, either directly or through a `doap:` file. When updating an existing project, omitting the name preserves its current value.
~~~yaml
project:
metadata:
key: tooling-trusted-releases
committee: tooling
name: Apache Trusted Releases
description: ATR is a platform through which committees of Apache Software Foundation (ASF) projects can make official ASF software releases. Official ASF releases are endorsed as an "act of the Foundation". It is therefore important that the foundation - its board, members, committees, and contributors - and the general public can have confidence in the releases.

~~~
`security_contact`, if set, must be either `security@apache.org` or `security@<committee>.apache.org`. The two threat-model fields are URLs: `threat_model_link` points at the published threat model, and `threat_model_src_link` at its source.
The version-scheme fields tell ATR how your version strings decompose into release cycles. Changing any of them lets ATR assign existing releases to whichever cycle their version now maps to, enabling lifecycle management features.
| Field | Type | Description |
| --- | --- | --- |
| `version_method` | `simple`, `semver` or `calver` | How version strings are interpreted. Defaults to `simple`. |
| `version_pattern` | regex | Validates a release version string. |
| `cycle_match` | regex | Groups versions into cycles; the first capture group is the cycle key. |
| `calver_format` | date format | For `calver` projects only, and `version_method: calver` must be set. Describes the version shape as a date format (e.g. `(YY.MM).N`); ATR compiles `cycle_match` from it, so set one or the other, not both. |
| `branch_template` | string | Names the release branch per cycle, e.g. `release-{cycle}`. |
A calver project sets `version_method: calver` and `calver_format` instead of `cycle_match`:
~~~yaml
project:
metadata:
key: tooling-trusted-releases
committee: tooling
version_method: calver
calver_format: "(YY.MM).N"
~~~
Alternatively, if you already have a DOAP file and want to continue to use it as the main source of project data, you can link the DOAP file into ATR like this:
~~~yaml
project:
metadata:
key: tooling-trusted-releases
committee: tooling
doap: https://raw.githubusercontent.com/apache/tooling-trusted-releases/refs/heads/main/doap_atr.rdf
policy:
vote_recipients:
to: private@tooling.apache.org
cc:
- dev@tooling.apache.org
announce_recipients:
to: announce@apache.org
features:
atr_sync: true
~~~
Note that in this case, for security reasons: you must use https, your link must live under apache.org or raw.githubusercontent.com/apache, and HTTP redirects will not be followed. (A `github.com/apache/...` link redirects to `raw.githubusercontent.com`, so link directly to the raw file as shown above.)
When using `doap:`, the project name comes from the DOAP file and must also start with `Apache `. To correct it, update the DOAP project's `<name>` element; a `name` supplied alongside `doap:` is ignored.
DOAP has no vocabulary for the ATR-only fields — `lifecycle_page`, the security fields, and the version-scheme fields. If you set any of those alongside a `doap:` link, they are kept as authored; the DOAP file supplies only the fields it can express.
<h3 id="policy">Release policy</h3>
The optional `policy` block configures how ATR runs your project, releases, votes and announcements. Every field is optional; set only the ones you need. ATR will default the rest.
The two recipient blocks, `vote_recipients` and `announce_recipients`, each take `to` (a single address), `cc`, and `bcc` (lists of addresses):
~~~yaml
project:
metadata:
key: tooling-trusted-releases
committee: tooling
policy:
vote_mode: email
min_hours: 72
license_check_mode: RAT
vote_recipients:
to: private@tooling.apache.org
source_artifact_paths:
- "*-src.tar.gz"
file_tag_mappings:
sources:
- "*-src.tar.gz"
~~~
The remaining fields:
| Field | Type | Description |
| --- | --- | --- |
| `vote_mode` | `manual`, `email` or `trusted` | How a release vote is conducted. Mutually exclusive with `manual_vote`. |
| `manual_vote` | boolean | Conduct the vote manually. Mutually exclusive with `vote_mode`. |
| `min_hours` | integer | Minimum hours a vote must remain open. |
| `license_check_mode` | `Both`, `Lightweight` or `RAT` | Which license check(s) to run. |
| `source_artifact_paths` | list of globs | Paths identifying source artifacts. |
| `binary_artifact_paths` | list of globs | Paths identifying binary artifacts. |
| `source_excludes_lightweight` | list of globs | Paths excluded from the lightweight license check. |
| `source_excludes_rat` | list of globs | Paths excluded from the RAT license check. |
| `file_tag_mappings` | map of label to globs | Groups release files under named tags. |
| `release_checklist` | string | Checklist shown to release managers. |
| `download_path_suffix` | string | Subdirectory the release is published under. A per-release template that may use `{{PROJECT_KEY}}`, `{{VERSION}}` and `{{MAJOR_VERSION}}`. |
| `start_vote_subject` / `start_vote_template` | string | Subject and body for the vote-start email. |
| `vote_comment_template` | string | Template for vote comments. |
| `finish_vote_template` | string | Template for the vote-result email. |
| `announce_release_subject` / `announce_release_template` | string | Subject and body for the announcement email. |
| `start_vote_template_url` / `vote_comment_template_url` / `finish_vote_template_url` / `announce_release_template_url` | string | A URL to fetch the matching email template from, instead of giving it inline. ATR fetches it each time it shows the email form. |
| `github_repository_name` | string | GitHub repository backing trusted publishing. |
| `github_repository_branch` | string | Branch within that repository. |
| `github_compose_workflow_path` / `github_vote_workflow_path` / `github_finish_workflow_path` | list of paths | Workflow files for each release stage. |
<h3 id="atrsync">Synchronizing to ATR</h3>
By default, your project definition will be synchronized to ATR. If you wish to opt out of this, setting `atr_sync: false` will allow you to define the values but opt-out of the sync process.
When sync is _enabled_, the .asf.yaml file is the authoritative source of project metadata. You can still edit the values manually in ATR, but the next push from your default branch will overwrite those edits with what the .asf.yaml file says.
By default, a push updates only the fields the file sets. A field you remove from the file keeps its value in ATR. To make the file the whole configuration, set `atr_sync_mode: full`:
~~~yaml
project:
features:
atr_sync: true
atr_sync_mode: full
~~~
With `full`, every field the file can set but leaves out is reset to the ATR default on each push. This is also the only way to clear a list from the file. The project name is never reset. The default mode is `merge`. ATR's export function can produce the file in either mode.
<h4 id="atrinit">Initial values from ATR</h4>
ATR seeds the metadata from the foundation's own project data at `projects.apache.org` (the same DOAP-derived data a `doap:` link re-imports), with committee membership from Whimsy. If you want to move the definition into your .asf.yaml file, you can export the yaml from ATR by using the export function on the project metadata page.
<h2 id="notif">Notification settings for repositories</h2>
Projects can set their notification targets for commits and GitHub issues/PRs/actions and discussions via .asf.yaml. Note that Jira issue email notification schemes are separate and require an Infra Jira ticket to change.
~~~yaml
notifications:
commits: commits@foo.apache.org
issues: issues@foo.apache.org
pullrequests: issues@foo.apache.org
jira_options: link label worklog
jobs: dev@foo.apache.org
discussions: issues@foo.apache.org
~~~
**NOTE**: Setting up notification schemes via `.asf.yaml` can only happen in the default (i.e. main/master/trunk etc.) branch of a repository, and each configuration change will cause your project's `private@` list to receive a notification of the change, for review purposes.
Settings made in .asf.yaml takes precedence over the original legacy mail targets (entered when you set up the repository). If a specific target scheme is not found in `.asf.yaml`, the legacy defaults will be used instead.
<h3 id="review">Reviewing your old (pre-.asf.yaml) configuration</h3>
If you wish to take a look at the default (old style) configuration for a repository, visit `gitbox.apache.org/schemes.cgi?$repository-name-here`, for instance `gitbox.apache.org/schemes.cgi?lucene-solr`.
<h3 id="split">Splitting email notifications based on context</h3>
You can divide pull requests and issues into sub-categories to split up the open/close emails and the comments/code review parts.
For instance, if a project wants new PRs to send an email to `dev@foo`, but wants any comments on that PR to go to `issues@foo`, employ the following configuration:
| notifications | email | notes |
| -------------------- | -------------------- | -------------------- |
| commits | `commits@foo.apache.org` | |
| issues | `issues@foo.apache.org` | Send all issue emails (new, closed, comments) to `issues@` |
| pullrequests_status | `dev@foo.apache.org` | Send new/closed PR notifications to `dev@` |
| pullrequests_comment | `issues@foo.apache.org` | Send individual PR comments/reviews to `issues@`. You can split `issues` into `issues_status` and `issues_comment` for sending issue emails to the appropriate targets. |
| | | |
The hierarchy for determining the email target for an action is:
1. If a specific status or comment target is specified, use that.
2. Otherwise, if a global issue/pull request target exists, use that.
3. Otherwise, fall back to the targets that were configured when the repository was set up.
4. Finally, fall back to dev@project for issues/PRs and commits@ for commits.
<h3 id="bypath">by-path commit emails</h3>
Projects may specify that commits to a repository that touches on specific paths will have a copy of the commit email sent to one or more specific addresses.
These paths are glob-enabled.
~~~yaml
notifications:
commits: commits@foo.apache.org
commits_by_path:
"sub-folder/*": foo@bar.apache.org
"docs/README.md":
- foo@bar.apache.org
- janedoe@apache.org
~~~
<h3 id="botschemes">Special schemes for bots</h3>
Projects may create special rules for bots such as dependabot on GitHub to have PR and issue activity from these directed to a distinct mailing list.
These special schemes are currently only available for pull requests and issues.
The general syntax for this is to append `_bot_$botname` to the scheme, for instance:
| notifications | email | notes |
| ---------------------------- | -------------------- | -------------------- |
| pullrequests | `issues@foo.apache.org` | Send all PR emails (new, closed, comments) to `issues@` |
| pullrequests_bot_dependabot | `private@foo.apache.org` | Send depandabot PRs to `private@` instead |
<h3 id="jiraoptions">Jira notification options</h3>
You can enable Jira notifications that will fire when a GitHub issue or pull request has a ticket in its title, such as `[TICKET-1234] Improve foo bar`.
You can set one or more of these options:
- `comment`: Add the PR/issue event as a comment in the referenced Jira ticket.
- `worklog`: Add the event as a worklog entry instead of a comment in the Jira ticket you reference.
- `label`: Add a 'pull-request-available' label to referenced tickets. **NOTE**: Some Jira projects have set limitations on who can add labels to tickets. If labels are not being added, you can address this by granting the Jira user `githubbot` access to your Jira space as a committer.
- `link`: When you create a GitHub PR/issue, embed a link to the PR or issue in the Jira ticket you reference.
You can concatenate the options you want to use as a string list, like this:
~~~yaml
notifications:
...
jira_options: link label comment
~~~
<p align="right"><a href="#top">Return to top</a></p>
<h2 id="deploy">Web site deployment service for Git repositories</h2>
The staging and publish features of the .asf.yaml file in a Git repository manage web site deployment.
**NOTE**: Web site staging and publishing features are applied for the repository in which you have specified staging and publishing. Thus, only specify them within the repository that contains your web site material, or you could end up seeing a list of source code files from your source repository on your site.
**NOTE**: Web site staging and publishing features are specific to the branch in which the .asf.yaml file resides and will not run without an accompanying `whoami`.
<h3 id="primer">Primer</h3>
A basic staging and publishing profile could be:
~~~yaml
# Staging and publishing profile for yourproject-website.git:
staging:
profile: ~
whoami: asf-staging
publish:
whoami: asf-site
~~~
This configuration enables a staging (live preview) web site at `yourproject.staged.apache.org` using the `asf-staging` branch of your repository, and deploys the `asf-site` branch of the repository to your main web site at `yourproject.apache.org`. Details below:
<h3 id="staging">Staging a web site preview domain</h3>
To enable staging a live preview of your project's web site, add a `staging` entry to the site repository's .asf.yaml file.
This example uses the imaginary `yourproject-website.git` with an `.asf.yaml` file containing the following entry:
~~~yaml
staging:
profile: beta
~~~
This would stage the current branch at `yourproject-beta.staged.apache.org`.
You can add multiple staging profiles and thus stage multiple branches for preview. This can be helpful when doing A/B evaluations of website contents and features.
You can also omit the profile value, and stage directly at `yourproject.staged.apache.org`:
~~~yaml
staging:
profile: ~
~~~
`~` (tilde) means "no value" in YAML.
**Preventing branch-override on cloning a branch**
Set a protection on multi-tenancy by specifying a `whoami` setting. If the setting's value does not match the name of the current branch, no checkout/update happens. You can have this in the `.asf.yaml` file on the `asf-staging` branch:
~~~yaml
staging:
profile: ~
whoami: asf-staging
~~~
When you clone that branch to a new branch like `asf-staging-copy`, the staging website server will notice that the value of `whoami` does not match `asf-staging-copy`, and will ignore that branch until you update the `whoami` to match it.
<h3 id="autostage">Automatically staging new branches with a dynamic profile</h3>
If you use features such as `autobuild`, you can automatically stage branches on `staged.apache.org` with the `autostage` keyword.
As with `autobuild`, it must match the branches you wish to autostage:
~~~yaml
staging:
profile: ~
whoami: asf-staging
autostage: site/*
~~~
Note that the autostage parameter must be `$foo/*`, e.g. `site/*` or `feature/*`.
The autostaging feature derives a profile from the branch name, thus `site/*` would stage all branches matching `site/*-staging` as `<project>-*.staged.apache.org`. For instance:
- Branch `site/foo` is autobuilt and the output goes to `site/foo-staging`.
- `site/foo-staging` matches `site/*` in the `autostage` command.
- The site is staged as `$project-foo.staged.apache.org`, for instance `tomcat-foo.staged.apache.org`.
<h3 id="publish">Publishing a branch to your project web site</h3>
**Notes**
- if you have previously used `gitwcsub` for website publishing, your first publish action using `.asf.yaml` will cause any existing `gitwcsub` or `svnwcsub` subscription to stop working. This ensures that there are no race conditions or "repository fights" going on when you publish.
- Although publishing the `asf-site` branch used to work without `.asf.yaml` being present, since May 2021 that file **must** be present at the root of the branch you wish to publish for everything (including soft purging the CDN cache on updates) to work correctly.
To publish a branch to your project website sub-domain (`yourproject.apache.org`), set up a configuration block called `publish` in your `.asf.yaml` file. Enable branch-protection through the `whoami` parameter, like so:
~~~yaml
publish:
whoami: asf-site
~~~
If, for whatever reason, a project wishes to revert to `gitwcsub` for publishing, remove the publish feature in your `.asf.yaml` file.
<h3 id="nondefault">Specifying a non-default hostname</h3>
By default, web sites are published at `$project.apache.org`, where `$project` is the sub-domain name of your project as determined by the repository name.
Some projects, like `openoffice.org`, have special domains and may publish to these by specifying a `hostname` attribute in the publish configuration block, as shown below.
This is also useful when a PMC manages several websites, like `comdev-site` and `comdev-events-site`.
~~~yaml
publish:
whoami: asf-site
hostname: www.openoffice.org
~~~
**NOTE**: You cannot specify your `$project.apache.org` hostname with this setting. It has to be inferred to prevent abuse. Also, please do not abuse this feature in any other way. (Thanks!)
<h3 id="subdir">Specifying a sub-directory to publish to</h3>
To publish to a sub-directory of the web site URL, specify a `subdir` value. Such checkouts can be useful for sub-projects.
For instance, if httpd wished to check out a repository into `httpd.apache.org/subproject`, they could use the following configuration:
~~~yaml
publish:
whoami: asf-site
subdir: subproject
~~~
**Known Issue**: In some cases (such as recent migration to this mechanism) the initial website check-in will clobber the sub-directory sites with a '404' error.
_Remediation_: Committing to the sub sites will trigger the mechanism to re-pull the content from sub-sites.
<h3 id="pelican">Pelican sub-directories for static output</h3>
The staging and deployment servers support the Pelican build `output/` sub-dir as the root directory for the web site. Thus, the website root can be either:
- The root of the git branch
- The `output/` directory at the root of the branch
<p align="right"><a href="#top">Return to top</a></p>
<h2 id="blog">Blog deployment service for Git repositories</h2>
You can deploy a project blog in the same manner as the project's website. It will be deployed as `$project.blog.apache.org`.
Deploy a blog by using the `type` parameter in your `publish` setting:
~~~yaml
publish:
whoami: asf-blog
type: blog
~~~
**NB**: The older style of `$project.apache.org/blog` may have file-path translation issues, we recommend using the `$project.blog.apache.org` URL for end-users.
<p align="right"><a href="#top">Return to top</a></p>
<h2 id="github">GitHub settings</h2>
<h3 id="triage">Assigning the GitHub 'triage' role to external collaborators</h3>
Projects may assign external (non-committer) collaborators the `triage` role for their repository. This allows them to assign, edit, and close issues and pull requests, without giving them write-access to the code.
Add such people to the `collaborators` stanza in the `github` section, as a list of GitHub IDs:
~~~yaml
github:
collaborators:
- Humbedooh
- gstein
~~~
**An invite will be sent, and they must accept the invitation before they appear in the GitHub list.**
To remove people as collaborators, remove them from the list. You may only have ten active collaborators at any given time per repository. If you need more, ask `vp-infra@apache.org` for an exception.
**Note**: If you wish to completely empty a previously non-empty list of collaborators, explicitly specify an empty list:
~~~yaml
github:
collaborators: []
~~~
<h3 id="autolink">Autolinks for Jira</h3>
Projects may specify one or more Jira projects to set up autolinking for in their repository, wherein any Jira ticket that is referred to automatically creates a link to the external Jira instance at ASF.
The following snippet would set up autolinking for the INFRA and AMBARI projects in a repository:
~~~yaml
github:
autolink_jira:
- INFRA
- AMBARI
~~~
The `autolink_jira` property can be a single string or a list of strings, each corresponding to a Jira project on `issues.apache.org`. It **must** adhere to the Jira project name syntax (uppercase alphabetical characters only).
We will evaluate the need for other autolink features.
<h3 id="branchpro">Branch protection</h3>
Projects can enable branch protection in their repos, including most of the sub-level protection features such as 'require status checks to pass before merging' , 'approval by at least $n people' , and 'require pull request reviews'. There are no default protections.
All GitHub branch protection rules are also enforced when pushing directly to ASF Gitbox.
For more details on Branch Protection Rules in general, please refer to the [documentation @ GitHub](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches).
> [!WARNING]
> The names of the required checks are not validated.
>
> If you modify the `contexts` and `checks` setting for the default branch, consider testing it on a **non** default
> branch first.
> A typo in these settings for the default branch will prevent you from modifying the `.asf.yaml` file itself.
Here are some examples:
~~~yaml
github:
protected_branches:
main:
required_status_checks:
# strict means "Require branches to be up to date before merging".
strict: true
# contexts are the names of checks that must pass.

The following settings are supported:

required_pull_request_reviews:
dismiss_stale_reviews: <boolean>

required_status_checks:

If not explicitly specified, these values will be used by default:
```yaml
required_signatures: false
required_linear_history: false
required_conversation_resolution: false
required_pull_request_reviews:
dismiss_stale_reviews: false
require_last_push_approval: false
require_code_owner_reviews: false
required_approving_review_count: 0
required_status_checks:
strict: false
contexts: ~
checks: ~
```
**Notes**
1. Enabling any of the above checks overrides what you may have set previously, so you'll need to add all the existing checks to your `.asf.yaml` file to reproduce any that Infra set manually for you.
2. These checks also are observed by Gitbox.
3. If you need to remove a required check in order to push a change to `.asf.yaml`, create an Infra Jira ticket with a request to have the check manually removed.
> [!NOTE]
> **How the synchronization between Gitbox and GitHub works under the hood**
>
> When you push to Gitbox, we handle all the synchronization in the Git update phase, which means GitHub is asked for each commit inside that push whether it is allowed.
> If as much as a single commit is disallowed, the sync process reverts and you get an error message explaining what went wrong.
Using the 'contexts' list will automatically set an app ID of `-1` (any source) for checks. If you wish to specify a specific source app ID, you can make use of the expanded `checks` list instead:
~~~yaml
github:
protected_branches:
main:
required_status_checks:
# strict means "Require branches to be up to date before merging".
strict: true
checks:
- context: gh-infra/jenkins
app_id: 1234
- context: another/build-that-must-pass
app_id: -1
...
~~~
All protected branches in the YAML must be dictionary entries. Thus, if you only want to disable force push from a branch, you can construct a **minimal dictionary**:
~~~yaml
github:
protected_branches:
master: {}
~~~
Branches that are not in your `.asf.yaml` file or are not dictionary entries are not protected and existing branch protections rules will be removed from them.
To completely remove all branch protection rules, set the protected_branches section to null:
~~~yaml
github:
protected_branches: ~
~~~
Removing the `protected_branches` section entirely has the same effect, provided the `github:` section still
contains other configuration: the previously configured branch protection rules are then removed. Note that
classic branch protection rules and [rulesets](#rulesets) can be active at the same time; GitHub evaluates both
and applies the most restrictive result.
<h3 id="customsubject">Custom subject lines for GitHub events</h3>
You can customize the subject lines for GitHub events (issues and pull requests being opened, closed, and commented on) on a per-repository basis.
You can customise the subject line either for individual events, or for all events (by using the `catchall` directive), following the Python f-string format:
~~~yaml
github:
custom_subjects:
new_pr: "[PR] {title} ({repository})"
close_pr: "Re: [PR] {title} ({repository})"
comment_pr: "Re: [PR] {title} ({repository})"
merge_pr: "Re: [PR] {title} ({repository})"
new_issue: "[I] {title} ({repository})"
comment_issue: "Re: [I] {title} ({repository})"
close_issue: "Re: [I] {title} ({repository})"
catchall: "[GH] {title} ({repository})"
new_discussion: "[D] {title} ({repository})"
edit_discussion: "Re: [D] {title} ({repository})"
close_discussion: "Re: [D] {title} ({repository})"
close_discussion_with_comment: "Re: [D] {title} ({repository})"
reopen_discussion: "Re: [D] {title} ({repository})"
new_comment_discussion: "Re: [D] {title} ({repository})"
edit_comment_discussion: "Re: [D] {title} ({repository})"
delete_comment_discussion: "Re: [D] {title} ({repository})"
~~~
The format follows a dictionary/hash with an event type and a subject line template.
<h4 id="supported-event-types">Supported event types</h4>
The following **event types** are currently supported:
| event type | notes |
| -------------------- | ---------------------------------------- |
| close_issue | Someone closes an issue |
| close_pr | Someone closes a pull request |
| comment_issue | Someone comments on an issue |
| comment_pr | Someone comments on a pull request |
| diffcomment | Someone comments on a segment of code in a pull request |
| merge_pr | Someone merges a pull request |
| new_issue | Someone createds an issue |
| new_pr | Someone createsd a pull request |
| catchall | If custom subjects are enabled for this repository, but no specific subject line template is defined for that event type, this will be used if present. If there is no `catchall`, and the event type does not have a template, the ASF default subject line will be used instead. |
| catchall_discussions | Custom catch-all for discussions, as these use slightly different variables. |
<h4 id="supported-template-variables">Supported template variables</h4>
The **subject line templates** support the use of the following variables only. Custom variables or calls are **not** supported.
| variable | notes |
| --------------- | ----------------------------------- |
| repository | The repository the event is for (but see the note below) |
| user | The GitHub user who triggered this event by creating, commenting on, merging or closing the issue/pr. |
| category | This will be either "issue" or "pr". |
| issue_id | The ID of this issue (same as `pr_id`, as GitHub uses the same internal number pool for both issues and pull requests). |
| pr_id | The ID of this pull request (same as issue_id). |
| link | The URL to this specific issue/pr or to the specific comment on it. |
| title | The title of the pull request, issue or discussion. |
| {action} | The generic action that happened (created/deleted/edited). |
| {url} | The URL for the discussion or comment that was affected (Discussions). |
| {body} | The body of text, either the discussion itself or a comment. |
| {action_human} | If a comment happened, this is a human-readable representation of the action. |
| {recipient} | The mailing list this was sent to. |
| {unsub} | The unsubscribe address of the mailing list this was sent to. |
**Note**: If your project uses multiple GitHub repositories, we recommend using the `repository` variable to let people know which repo the email relates to. If your project has a single repo or does not use GitHub integration much (or at all), you can omit that variable.
<h3 id="default_branch">Default branch</h3>
To change the default GitHub repository branch (which is the landing branch when users browse to `github.com/apache/<repository>` and the default branch pull requests are initially based on, etc.), go to `https://gitbox.apache.org/boxer/` and select the 'Repositories' menu, 'Change Default Branch' option (Project PMC members only). If you are renaming the default branch and the new default branch does not yet exist, you can ask Infra to rename the branch at the same time. Include a **link** to the mailing list thread where the change of the default was agreed.
<h3 id="delete_branch">Delete branch on merge</h3>
Add this snippet below so branches get auto-deleted upon PR merges to your default branch:
~~~yaml
github:
del_branch_on_merge: true
~~~
> [!WARNING]
> This setting is deprecated and has been moved to [pull_requests.del_branch_on_merge](#pull_requests).
You can revert this by setting the variable back to false. (Merely removing the entry will not do that).
<h3 id="depend_alerts">Dependabot alerts and updates</h3>
Projects can enable and disable Dependabot alerts and automatic security update pull requests:
~~~yaml
github:
dependabot_alerts: true
dependabot_updates: false
~~~
<h3 id="GHA_build_status">GitHub Actions build status emails</h3>
You can add a jobs directive in the standard notifications section to have GitHub actions send you notifications when a build fails, or when it transitions from failure to success:
~~~yaml
notifications:
jobs: jobs@foo.apache.org
~~~
This triggers emails when a workflow run fails or if it succeeds after a series of failures. We do not send notifications on normal, successful runs, so as to not spam too much.
<h3 id="pages">GitHub Pages</h3>
Projects that use GitHub for website publishing can enable/update GitHub Pages settings, by specifying which branch (and optional path) to publish:
~~~yaml
github:
ghp_branch: master
ghp_path: /docs
~~~
The `ghp_branch` setting can **only** be your default branch (e.g. master, main, ...) or `gh-pages`.
**Note**: This is subject to change as GitHub is relaxing the rules.
The `ghp_path` setting should **always** be specified. It can be either `/docs` or `/`. If not specified, it will default to `/docs`.
<h3 id="pull_requests">Pull Request settings</h3>
Projects can enable/disable various settings for PRs:
- allow [auto-merging](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/incorporating-changes-from-a-pull-request/automatically-merging-a-pull-request) of PRs
- allow [updating](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/keeping-your-pull-request-in-sync-with-the-base-branch) head branches of PRs
- automatically [delete](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/configuring-pull-request-merges/managing-the-automatic-deletion-of-branches) head branches after merge
- cap the number of open PRs a user without write access may have at one time (see [creation cap](#pr_creation_cap) below)
Example:
~~~yaml
github:
pull_requests:
# allow auto-merge
allow_auto_merge: true
# enable updating head branches of pull requests
allow_update_branch: true
# auto-delete head branches after being merged
del_branch_on_merge: true
~~~
<h4 id="pr_creation_cap">Pull request creation cap</h4>
You can limit the number of open pull requests a user **without write access** may have open at one
time. This is GitHub's [pull request creation cap](https://github.blog/changelog/2026-06-17-limit-open-pull-requests-for-users-without-write-access/)
interaction limit, and it helps mitigate spam or automated PR floods. Users with write access are not
affected by the cap.
~~~yaml
github:
pull_requests:
creation_cap:
# turn the cap on or off
enabled: true
# maximum number of open PRs a user without write access may have (1-1000)
max_open_pull_requests: 5
# count draft pull requests toward the cap as well
include_drafts: true
# GitHub logins that may open PRs regardless of the cap
bypass_users:
- octocat
- monalisa
~~~
Supported settings:
~~~yaml
enabled: <boolean> # required
max_open_pull_requests: <int> # optional, 1-1000; if omitted, GitHub's default is used
include_drafts: <boolean> # optional; whether draft PRs count toward the cap
bypass_users: <list of strings> # optional, at most 100 GitHub logins; see below
~~~
Set `enabled: false` to turn the cap off. Removing the `creation_cap` section also disables a cap that
was previously managed by `.asf.yaml`.
By default GitHub does not count draft pull requests toward the cap, so a user could open any number
of drafts. Set `include_drafts: true` to [count them too](https://github.blog/changelog/2026-10-08-draft-pull-requests-count-toward-pull-request-limits/).
Removing `include_drafts` after it was set turns it back off. If you leave it out and never set it,
`.asf.yaml` does not change it, and a value set by hand in the repository settings stays.
When `bypass_users` is present, GitHub's bypass list for the cap is made to match it exactly: users
listed here but missing on GitHub are added, and users on GitHub but not listed here are removed,
including users that were added by hand in the repository settings. Set `bypass_users: ~` to empty
the list. When `bypass_users` is omitted, the bypass list is left untouched, so a list maintained
through the repository settings keeps working. The list is synced whether the cap is enabled or not, so
turning the cap off with `enabled: false` keeps `bypass_users` in place for when it is turned back on.
Every login to be added is checked against GitHub first; the run fails and names the unknown logins
before anything is changed. A noop run does the same check when a `GH_TOKEN` is available.
<h3 id="copilot_code_review">Copilot code review</h3>
Copilot code review can review code written in any coding language and provide feedback. It reviews your code from multiple angles to identify issues and suggest fixes, which you can apply with a couple of clicks.
Projects can enable automatic [GitHub Copilot code review](https://docs.github.com/en/copilot/how-tos/agents/copilot-code-review/configuring-automatic-code-review-by-copilot) on pull requests:
~~~yaml
github:
copilot_code_review:
enabled: true
review_drafts: false
review_on_push: true
~~~
This creates (or updates) a repository ruleset named `Copilot Code Review`, scoped to the default branch.
Supported settings:
~~~yaml
enabled: <boolean>
review_drafts: <boolean> # optional, default false
review_on_push: <boolean> # optional, default false
~~~
Set `enabled: false` to disable this behavior. Removing the `copilot_code_review` section also removes an existing Copilot ruleset that was previously managed by `.asf.yaml`.
As an alternative, you can configure Copilot review through [`rulesets`](#rulesets). Validation fails if both
`copilot_code_review` and `rulesets` overlap, either by managing a ruleset named `Copilot Code Review`
or by defining a `copilot_code_review` rule type in `rulesets`.
<h3 id="rulesets">Rulesets</h3>
Rulesets help you control how people can interact with branches and tags in a repository.
Projects can manage GitHub repository rulesets using one of two styles:
- Convenience syntax (recommended)
- Raw payload syntax (advanced)
Convenience syntax (recommended):
~~~yaml
github:
rulesets:
- name: "Branch Protection"
type: branch
branches:
includes:
- "main"
- "release/*"
excludes: []
bypass_teams:
- "release-managers"
restrict_deletion: true
restrict_force_push: true
required_signatures: true
required_linear_history: true
required_conversation_resolution: true
required_pull_request_reviews:
dismiss_stale_reviews: true
require_last_push_approval: false
require_code_owner_reviews: true
required_approving_review_count: 2
required_status_checks:
- name: "gh-infra/jenkins"
app_slug: "jenkins"
- name: "build-and-test"
app_slug: -1
~~~
Notes:
- `enforcement` is hardcoded to `active` for this syntax.
- `bypass_teams` accepts team slugs and resolves them to IDs automatically.
- `required_status_checks` accepts either a list of strings (check context, any source) or mappings with `name` and optional `app_slug`.
- `required_status_checks.app_slug` accepts either a numeric ID or app slug; slugs are resolved to `integration_id`.
- `required_status_checks_strict` defaults to `false` (set it to `true` to require branches to be up to date before merge).
- If `branches`/`refs` is omitted for `type: branch`, it defaults to `~DEFAULT_BRANCH`.
- `restrict_deletion` and `restrict_force_push` default to `true` in convenience syntax.
- Set `restrict_deletion: false` and/or `restrict_force_push: false` to disable those rules for a convenience entry.
- `deletion` and `non_fast_forward` are raw rule types under `rules`, not convenience top-level keys.
- Convenience entries may intentionally resolve to `rules: []` (for example, while staging migration changes).
- If `required_conversation_resolution` is set, `required_pull_request_reviews` must be present as well.
Validation and reconciliation behavior:
- Each `rulesets` entry must use exactly one style: convenience syntax or raw payload syntax.
- Mixing convenience syntax keys and raw payload syntax keys in the same entry is not supported.
- Ruleset `name` is the reconciliation key and must be unique within `github.rulesets`.
- If a ruleset with that `name` exists, it is updated.
- If it does not exist, it is created.
- If a previously managed ruleset `name` is removed from `.asf.yaml`, it is deleted.
Set `rulesets: ~` (or remove the `rulesets` key) to remove previously managed rulesets managed by `.asf.yaml`.
Raw payload syntax (advanced):
Use raw payload syntax (`target`, `conditions`, `rules`, `bypass_actors`, etc.) when you need full Rulesets API control.
Raw payload example (including explicit safety rules):
~~~yaml
github:
rulesets:
- name: "Custom branch policy"
target: branch
enforcement: active
conditions:
ref_name:
include:
- "~DEFAULT_BRANCH"
exclude: []
rules:
# Restrict deletions: only bypass actors can delete matching refs.
- type: deletion
# Block force-push/non-fast-forward updates for matching refs.
- type: non_fast_forward
- type: required_signatures
- type: required_linear_history
- type: pull_request
parameters:
dismiss_stale_reviews_on_push: true
require_code_owner_review: true
require_last_push_approval: false
required_approving_review_count: 2
required_review_thread_resolution: true
- type: required_status_checks
parameters:
strict_required_status_checks_policy: false
required_status_checks:
- context: gh-infra/jenkins
integration_id: -1
~~~
Rule summary for the raw payload example:
- `deletion`: Only bypass actors can delete matching branches/tags.
- `non_fast_forward`: Blocks force-push and other non-fast-forward updates.
- `required_signatures`: Requires commits with verified signatures.
- `required_linear_history`: Disallows merge commits on matching refs.
- `pull_request`: Requires pull requests and controls review policy.
- `required_status_checks`: Requires specific CI checks before merge/update.
For the full list of supported rules and semantics, see GitHub docs:
- [Available rules for rulesets](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-rulesets/available-rules-for-rulesets)
- [Repository rulesets REST API](https://docs.github.com/en/rest/repos/rules?apiVersion=2022-11-28#get-all-repository-rulesets)
### Migrating from `protected_tags`
`protected_tags` is deprecated on GitHub and no longer applied by `.asf.yaml`. Use `rulesets` with `type: tag`
instead:
~~~yaml
github:
rulesets:
- name: "Release tags"
type: tag
branches:
includes:
- "rel/*"
- "v*.*.*"
excludes: []
~~~
<h3 id="merge">Merge buttons</h3>
Projects can enable/disable the `merge PR` button in the GitHub UI and configure which actions to allow by adding the following configuration (or derivatives thereof):
~~~yaml
github:
enabled_merge_buttons:
# enable squash button:
squash: true
# default commit message when merging with a squash commit
# can either be: DEFAULT | PR_TITLE | PR_TITLE_AND_COMMIT_DETAILS | PR_TITLE_AND_DESC
squash_commit_message: PR_TITLE
# enable merge button:
merge: true
# default commit message when merging with a merge commit
# can either be: DEFAULT | PR_TITLE | PR_TITLE_AND_DESC
merge_commit_message: PR_TITLE_AND_DESC
# disable rebase button:
rebase: false
~~~
At least one of `squash`, `merge`, or `rebase` must be true.
<h3 id="repo_features">Repository features</h3>
Projects can enable/disable GitHub repository features to support their documentation and development model.
~~~yaml
github:
features:
# Enable wiki for documentation
wiki: true
# Enable issue management
issues: true
# Enable projects for project management boards
projects: true
# Enable discussions
discussions: true
~~~
**NOTE**: When enabling discussions, you must specify a valid <a href="#notif">notification target</a> for discussions.
<h3 id="repo_meta">Repository metadata</h3>
**NOTE**: Repository defaults via `.asf.yaml` may only be set in the main/master/trunk or default branch of a repository,
Projects can update their GitHub metadata (repository description, homepage and labels) via `.asf.yaml` like this:
~~~yaml
github:
description: "JSONP module for Apache Foobar"
homepage: https://foobar.apache.org/
labels:
- json
- jsonp
- foobar
- apache
~~~
To remove labels from the repository, remove them from the list. You may only have 20 active labels at any given time per repository.
**NOTE**: Metadata changes will only apply if you specify them in the `.asf.yaml` file in the master (or otherwise default) branch of a repository.
<h3 id="tag_protect">Tag protection</h3>
⚠️ **Deprecated**
GitHub tag protection rules were sunset in February 2024 and are no longer applied.
This section is retained for historical reference only.
As with branch protection rules, you can enable tag protection rules. These rules allow anyone with write-access to create a tag that matches the rule, but does not allow the tag to be deleted or overwritten.
Tag protection rules follow a simple GLOB format, and support an arbitrary number of tag patterns:
~~~yaml
github:
protected_tags:
- "rel/*"
- "v*.*.*"
~~~
**NOTE**: Tag protections have been sunset by GitHub as of 02/12/2024 and will thus not be applied anymore.
Use [`rulesets`](#rulesets) with `type: tag` (or raw rulesets payloads with `target: tag`) for tag protection policies.
<h3 id="environments">Repository deployment environments</h3>
Projects can create deployment environments and deployment branch policies like this:
~~~yaml
github:
environments:
pypi:
required_reviewers:
- id: user_id
type: User
wait_timer: 5
deployment_branch_policy:
protected_branches: false
policies:
- name: main
type: branch
- name: 1.2.0
type: tag
- name: "release/*"
test-pypi:
required_reviewers:
- id: user_id
type: User
wait_timer: 60
deployment_branch_policy:
protected_branches: true
~~~
The above example creates two deployment environments, `pypi` and `test-pypi`.
- `pypi` has a deployment branch policy with a custom list of branches in the `policies` list.
- `test-pypi` has a deployment branch policy to set up all protected branches from the repository.
The `environments` section is a dictionary of environment names, each with a dictionary of settings. The settings are:
```yaml
required_reviewers:
- id: <string> | <int>
type: 'User' | 'Team'
wait_timer: <int>
prevent_self_review: <bool>
deployment_branch_policy:
protected_branches: <bool>
policies:
- name: <string>
type: 'branch' | 'tag'
```
- `required_reviewers`: A list of reviewers who must approve the deployment. (The `id` is the GitHub user ID or username / team slug.)
- `wait_timer`: To delay a job for a specific number of minutes after the job is initially triggered.
- `prevent_self_review`: If set to `true`, the user that triggered the deployment cannot also approve it as a `required_reviewer`.
- `deployment_branch_policy`: A dictionary of branch policy settings.
- `protected_branches`: If set to `true`, the deployment branch policy will be set up to allow deploying from all protected branches.
- `policies`: A list of branch / tag policies to apply for this environment. Only matching branches / tags can deploy to the environment.
**Note**: Only one of the settings in `protected_branches` and `policies` can be active when specifying a `deployment_branch_policy`.
**Note**: Only teams with a team visibility of `visible` can be specified as `required_reviewers`, `secret` teams will be ignored by GitHub.
If you do not explicitly specify values, the system uses these values by default:
```yaml
required_reviewers: []
wait_timer: 15
prevent_self_review: true
deployment_branch_policy: ~
```
- by default `protected_branches` is set to `false`
- the default `type` for a `required_reviewer` is `User`
- the default `type` for a `deployment_branch_policy` is `branch`
<p align="right"><a href="#top">Return to top</a>
<h3 id="oidc_subject">GitHub Actions OIDC subject claim</h3>
Workflows that log in to a cloud provider with GitHub's [OpenID Connect tokens](https://docs.github.com/en/actions/concepts/security/openid-connect)
are trusted by the token's `sub` claim. By default it names the repository by owner and name, e.g.
`repo:apache/foo:ref:refs/heads/main`. With the [immutable format](https://docs.github.com/en/actions/reference/security/oidc#immutable-subject-claims)
it also carries the owner and repository IDs, e.g. `repo:apache@47359/foo@123456789:ref:refs/heads/main`, so a
renamed, deleted or re-created repository can no longer match a trust policy written for the old one.
Repositories created after July 15, 2026 use the immutable format already; older ones keep the old format
until they opt in.
~~~yaml
github:
oidc_subject:
# use the immutable, ID-based subject claim format
use_immutable_subject: true
~~~
Supported settings:
~~~yaml
use_immutable_subject: <boolean> # optional; opt in to (or out of) the immutable format
include_claim_keys: [<string>, ...] # optional; a custom claim template, e.g. [repo, context, job_workflow_ref]
~~~
Without `include_claim_keys` the subject uses GitHub's default template. With it, the subject is built from
the listed [claim keys](https://docs.github.com/en/actions/reference/security/oidc#customizing-the-subject-claims-for-an-organization-or-repository)
instead. Removing `include_claim_keys`, or the whole `oidc_subject` section, goes back to the default template.
`use_immutable_subject` is only changed when it is written down. Removing it, or the section, leaves the
format as it is: switching a repository back to the old format breaks every trust policy written for the
immutable one, so it takes an explicit `use_immutable_subject: false`.
**Note**: a trust policy written for one format does not match tokens in the other. Update the policies in
your cloud account in the same change, or first allow both subjects, then drop the old one.
<p align="right"><a href="#top">Return to top</a>
<h2 id="static">Generating static website content</h2>
See also <a href="https://infra.apache.org/project-site.html">Managing your project web site</a>, which lists more options and examples of website generation.
**NOTE**: Website staging and publishing features are specific to the branch in which the `.asf.yaml` resides and will not run without an accompanying `whoami`.
<h3 id="autobuild">Automatically building new branches</h3>
The Pelican builder supports a feature called `autobuild`. When enabled and assigned a pattern, it builds any branch that matches the pattern, and puts the output in a branch with the same root name but ending in `-staging`.
As an example, setting autobuild to `site/*` would automatically build the branch `site/foo`, and put the resulting web site in `site/foo-staging`. This can be mixed in with the standard parameters:
~~~yaml
pelican:
whoami: master
target: asf-site
autobuild: site/*
~~~
<h3 id="buildpub">Building and publishing at the same time</h3>
You can build and publish your website at the same time by employing both the `pelican` and `publish` configurations in your `.asf.yaml` file:
~~~yaml
pelican:
whoami: master
target: asf-site
publish:
whoami: asf-site
~~~
The configuration snippet above would, when present in both master and asf-site branches, build the web site from the master branch, then push the result to the asf-site branch and publish that branch as your project web site.
Likewise, you can employ auto-build-and-stage:
~~~yaml
pelican:
whoami: master
target: asf-site
staging:
whoami: asf-site
profile: ~
~~~
This would build your site from the master branch, push the result to the asf-site branch and then stage that result on your staging domain.
<h3 id="config_notif">Configuring Notifications</h3>
The Pelican builder has an optional keyword, `notify` which defines a list to which a status report will be sent upon job completion. If no option is specified, a notification will be sent to `notifications@infra.apache.org` instead.
~~~yaml
pelican:
whoami: master
target: asf-site
notify: list@apache.org
~~~
<h3 id="jekyll_cms">Jekyll CMS</h3>
Projects can build their websites automatically using <a href="https://jekyllrb.com/" target="_blank">Jekyll</a>. This solution allows the use of custom plugins. Content generated this way can be staged or pushed directly to production when it is used in conjunction with the staging or publishing configuration options.
You can optionally specify a named output directory as `outputdir`. If a value is not specified for this property, it defaults to 'output'.
**Warning** Do not change `destination` in Jekyll's `_config.yaml` file. It must stay as is and output the generated files into a `_site` folder.
To set up an automatic build, add a jekyll section to `.asf.yaml`:
~~~yaml
jekyll:
whoami: jekyll-source-branch
target: asf-staging-jekyll # output branches need to be asf-site OR asf-staging*
# outputdir: outputdir # MAY be needed, but generally can be left out
~~~

**Note**: In 2019 Infra created `ASF-Pelican` as a structure and template for projects to use to build their websites, and for the ASF's own website.
In 2024, Infra moved from ASF-Pelican to the ASF **Infrastructure Pelican Action** GitHub Action to perform the same functions without being closely tied to BuildBot. The repository for this GHA is <a href="https://github.com/apache/infrastructure-actions/tree/main/pelican" target="_blank">github.com/apache/infrastructure-actions/tree/main/pelican</a>.
We are updating the help documentation for Pelican, which starts at <a href="https://infra.apache.org/asf-pelican.html" target="_blank">infra.apache.org/asf-pelican.html</a>, to provide what you need to know about the ASF Pelican GHA.

Projects can automatically build web sites using the <a href="https://blog.getpelican.com/" target="_blank">Pelican Static Site Generator</a> and have the result either staged or pushed directly to production (with the addition of a staging or publish configuration, as seen above).
To set up an automatic build, add a Pelican section to `.asf.yaml`:
~~~yaml
pelican:
whoami: master
target: asf-site
~~~
The above configuration generates the site using Pelican and pushes only the created output to the `asf-site` branch. An example website repository that uses the Pelican auto-build feature is the <a href="https://github.com/apache/infrastructure-website" target="_blank">Infrastructure website</a>.
Our Pelican builds support GFM (GitHub-Flavored Markdown), meaning you can edit websites using the GitHub UI and instantly get a preview of your page before pushing it to the build/publish process.
GFM is enabled by default, but will change to standard markdown if you have PLUGINS defined in your `pelicanconf.py` file. To explicitly enable GFM along with other manually defined plugins, you may specify gfm as a plugin, and it will be woven into the build.
Furthermore, you can build off one branch and publish to another using the `target` parameter, as seen above. If you leave this parameter out, the build process pushes the generated site to the same branch it built from (in the `output/ base` directory).
Pelican auto-builds support using different themes via the `theme` argument to specify the directory that contains your theme. This is equivalent to the `-t` switch in Pelican.
<h3 id="pg_count">Pelican - Requiring minimum page count</h3>
The Pelican builder has an optional keyword, `minimum_page_count`, which sets a lower limit to the number of pages that must be built for the builder to succeed and stage/publish the result.
This can be used to prevent misconfigured builds from publishing partial or blank web sites. The command expects a positive integer in order to check:
~~~yaml
pelican:
whoami: master
target: asf-site
minimum_page_count: 200 # If fewer than 200 html pages were built, cancel the build!

<h2>Deprecated features</h2>
<h3 id="whitelisting">Jenkins PR whitelisting</h3>
**NOTE**: This no longer works. This feature was based on a Jenkins plugin that is no longer maintained and has been removed from use. The code still exists in `asfyaml.py` for the time being while we research a similar plugin for possible
use. Ignore this feature for now.
For projects using Jenkins for CI testing, PRs are generally only built when a committer submits one. Projects **may** choose to designate a GitHub 'safe/reliable' person using the jenkins/github_whitelist feature:
~~~yaml
jenkins:
github_whitelist:
- janedoe
- githubmonkey
- papasmurf1234
- dependabot[bot]
~~~
The GitHub IDs listed here would have access to start builds based on PRs, in addition to the committers on the project. For automated accounts, such as Dependabot, you need to add the `[bot]` suffix to its name.

These features have not been implemented in production yet, but are documented here for future use.
None currently
If you would like to add features please open a pull request or propose your changes via (github issue or infra ticket TBD.) The whole logic is defined in the `asfyaml.py` file that you create.

The code that interprets your `.asf.yaml` and applies the configuration
to the relevant systems is not public, but if you're an [Apache Committer](https://github.com/orgs/apache/teams/apache-committers)
you can find it in [asfyaml.py](https://github.com/apache/infrastructure-p6/blob/production/modules/gitbox/files/asfgit/package/asfyaml.py)
