vCluster Documentation Release Skill

Overview

This skill automates the vCluster documentation release process, handling version updates, configuration changes, and SEO setup for new vCluster releases.

Versioning Timing: rc-1 Process

Starting with vCluster v0.33, docs versioning happens at rc-1, NOT on release day.

How it works

1. At rc-1: Create the new docs version the same day rc-1 is cut
2. Deploy hidden: The version is deployed but HIDDEN from the public version dropdown — users cannot discover it via the UI
3. Validation window: The hidden version can be accessed via Netlify preview URL or by manually changing the version in the URL, allowing the platform team and contributors to validate against real deployed docs
4. On release day: A single "config flip" PR exposes the version in the dropdown. This PR is small, reviewable, and safe to merge by anyone with merge rights
5. Backport flow: Contributors continue targeting vcluster/ on main as usual. If a change needs to land in the upcoming release, add the backport-v0.33 label to the PR

Config flip PR (release day)

The config flip PR changes only the version visibility in docusaurus.config.js:

• Moves the new version entry from hidden to visible in the dropdown
• Updates lastVersion to point to the new version
• Demotes the previous stable version label (removes "Stable" suffix)
• Updates SEO sitemap priorities, announcement bar, and netlify redirect (adds new version, removes previous)

This separation means all the heavy lifting (version creation, content, link fixes) is done during the rc-1 window, and release day is a low-risk config change.

When to Use This Skill

Trigger this skill when:

• User mentions "vCluster release", "new vCluster version", or "prepare vCluster docs"
• User mentions "rc-1" or "release candidate" for vCluster docs
• Working on Linear issue with title matching "docs updates for vCluster vX.Y release"
• User asks to prepare docs for a new vCluster version (e.g., 0.33.0)
• User references the release checklist or ENG-XXXX release issues
• User asks to create the "config flip" PR for release day

Note: This skill is for vCluster releases only. Platform releases have a separate skill (platform-docs-releaser).

Prerequisites

Before starting:

1. User must create versioned docs folder — Run: npm run docusaurus docs:version:vcluster X.Y.Z
2. Verify version exists: Check vcluster_versions.json and vcluster_versioned_docs/version-X.Y.Z/ exist
3. CLI docs should be generated — Usually automated, but verify 90+ .md files in vcluster_versioned_docs/version-X.Y.Z/cli/

Release Workflow

Part 0: Timing Decision

• rc-1 day: Perform Parts 1-3 (version creation + hidden deploy)
• Release day: Perform Part 4 (config flip PR only)

Part 1: Next Branch Merge (If Needed)

When: Only if next branch contains preview docs that need to go to main

Process:

1. Check if next has unique content:

   git log --oneline --no-merges origin/next ^main | grep -v "Merge remote-tracking branch"
   

2. If next has content to merge:

   • Create PR from next → main with squash merge
   • PR Title: docs: merge next branch for vX.Y release
   • PR Body: "Squash merge of preview docs from next branch"
   • Why PR? Branch auto-delete + allows review + CI checks

3. Merge command:

   gh pr create --base main --head next \
     --title "docs: merge next branch for vX.Y release" \
     --body "Squash merge of preview docs from next branch"
   
   # After review:
   gh pr merge <pr-number> --squash
   

Note: Currently next only has merge commits, so this step can be skipped for now.

Part 2: Configuration Updates (rc-1 — hidden deploy)

At rc-1, the version is added to the build but hidden from the dropdown. Do NOT change lastVersion, SEO, netlify redirect, or announcement bar — those are Part 4 (release day).

1. Update docusaurus.config.js — vCluster plugin config

Add the new version to onlyIncludeVersions and versions with hidden/unreleased flags:

lastVersion: "0.YY.0",  // DO NOT CHANGE — stays on current stable
onlyIncludeVersions: ["current", "0.XX.0", "0.YY.0", ...],  // Add new version
versions: {
  current: {
    label: "main 🚧",
  },
  "0.XX.0": {  // NEW ENTRY — hidden pre-release
    label: "v0.XX",
    banner: "unreleased",  // Shows warning banner on every page
    badge: true,
    noIndex: true,          // Prevents search engine indexing
  },
  "0.YY.0": {  // KEEP as-is — still current stable
    label: "v0.YY Stable",
    banner: "none",
    badge: true,
  },
  // ... rest unchanged
}

2. Update vcluster/_fragments/default-k8s-version.mdx — default Kubernetes version

Check the default k8s version for this release. The source of truth is controlPlane.distro.k8s.image.tag in config/values.yaml of the vcluster OSS repo.

If the tag changed from the previous release, update the fragment:

:::note
vCluster deploys Kubernetes **vX.YY.Z** by default. To use a different version, set `controlPlane.distro.k8s.image.tag` in your `vcluster.yaml`.
:::

This fragment is used on quick-start and deploy pages. Because it lives in vcluster/_fragments/, the versioning command snapshots it into the new versioned docs folder automatically — older docs retain their pinned version.

3. Update src/config/versionConfig.js — hide from dropdown

Add the version to the hidden array so it doesn't appear in the version dropdown:

export const vclusterHiddenVersions = ["0.XX.0"];
export const platformHiddenVersions = [];

This is the single source of truth for hiding versions. Two custom components consume it:

• Desktop sidebar (src/theme/DocSidebar/Desktop/Content/index.js): filters useVersions() and passes visible names to DocsVersionDropdownNavbarItem versions prop
• Mobile TOC (src/theme/TOCCollapsible/index.js): filters useVersions() before rendering

Result: the version is built, accessible via direct URL (e.g., /docs/vcluster/0.XX.0/), shows the "unreleased" banner, but does not appear in the dropdown.

Part 3: Verification (rc-1)

AI performs:

1. ✅ Verify versioned docs exist: ls -la vcluster_versioned_docs/version-0.XX.0/
2. ✅ Count CLI docs: ls vcluster_versioned_docs/version-0.XX.0/cli/*.md | wc -l (expect 90+)
3. ✅ Check vcluster_versions.json includes new version
4. ✅ Default k8s version fragment updated if version changed (vcluster/_fragments/default-k8s-version.mdx)
5. ✅ All config changes applied
6. ✅ Version is hidden from dropdown (in vclusterHiddenVersions array in versionConfig.js)

User performs:

1. Build check: npm run build (not AI's responsibility)
2. Review enterprise/pro tags (manual)
3. Update support dates in vcluster/manage/upgrade/supported_versions.mdx
4. Update compatibility matrix in same file
5. Verify partials PR merged (automated PR)
6. Run hurl tests after PR deployed

Part 4: Config Flip PR (Release Day)

This is the release-day action. All heavy work was done at rc-1. This PR only flips visibility.

PR title: docs: expose vCluster 0.XX docs in version dropdown PR body: "Config flip to make the pre-deployed v0.XX docs visible in the version dropdown. All content was deployed at rc-1."

1. src/config/versionConfig.js — unhide from dropdown

export const vclusterHiddenVersions = [];  // Remove the version string

2. docusaurus.config.js — promote to stable

lastVersion: "0.XX.0",  // Was 0.YY.0 — now points to new version
versions: {
  "0.XX.0": {
    label: "v0.XX Stable",  // Was "v0.XX" — add "Stable"
    banner: "none",          // Was "unreleased" — remove banner
    badge: true,
    // noIndex removed — allow search engine indexing
  },
  "0.YY.0": {
    label: "v0.YY",  // Was "v0.YY Stable" — demote
    banner: "none",
    badge: true,
  },
}

3. src/config/docsearch.js — update stable version for search

vcluster: {
  pluginId: "vcluster",
  stableVersion: "0.XX.0",  // Was "0.YY.0" — update to new stable
  stableLabel: "v0.XX Stable",
},

This drives search modal version boosting (stable docs get pageRank: 120, others get 60 or 20) and the default version filter on the /docs/search page. Without this update, search will continue biasing toward the old stable version.

4. docusaurus.config.js — SEO sitemap priorities

if (item.url.match(/\/vcluster\/0\.XX\.0\//) ||
    item.url.match(/\/platform\/X\.Y\.0\//)) {
  return { ...item, priority: 1.0, changefreq: 'daily' };
}

5. docusaurus.config.js — announcement bar

announcementBar: {
  id: "vcluster-0-XX-release",
  content: '... vCluster 0.XX ...',
},

6. netlify.toml — redirect

CRITICAL: Add the redirect for the new lastVersion AND remove the redirect for the previous lastVersion (0.YY.0). The previous version is still in onlyIncludeVersions — its versioned URL serves real content and must not redirect.

# ADD this block for the new lastVersion (canonical URL is the unversioned path)
[[redirects]]
  from = "/docs/vcluster/0.XX.0/*"
  to = "/docs/vcluster/:splat"
  status = 301
  force = true

# REMOVE the block for 0.YY.0 — it is now a live versioned URL, not the lastVersion

Only two categories of versions belong in this redirect section:

• The current lastVersion (whose canonical URL is the unversioned path)
• Truly EOL/archived versions that are no longer in onlyIncludeVersions

7. hack/test-vcluster-0.XX.hurl — create hurl test

Copy from previous version, update version numbers. Hurl tests run AFTER PR is deployed to Netlify preview.

This PR is small, reviewable, and safe to merge by anyone with merge rights.

Division of Responsibilities

AI Handles (Items 2-5):

• ✅ Update banner - announcementBar.content
• ✅ Update netlify redirect - netlify.toml
• ✅ Verify CLI commands - Check files exist
• ✅ Create hurl test - Create new test file
• ✅ Update search stable version - src/config/docsearch.js stableVersion field (release day only)

User Handles (Items 1, 6-9):

• Create versioned docs - npm run docusaurus docs:version:vcluster X.Y.Z
• Review enterprise/pro tags - Manual review of <ProAdmonition> tags
• Partials PR - Verify automation ran
• Update support dates - Edit vcluster/manage/upgrade/supported_versions.mdx
• Update compatibility matrix - Edit same file
• Run build - npm run build
• Run hurl tests - After PR deployed

Common Patterns

Version Number Pattern

• Major.Minor.Patch: 0.30.0
• Label format: v0.30 (without patch)
• Label stable: v0.30 Stable (current release)
• Label EOL: v0.26 (EOS) (old versions)

onlyIncludeVersions Pattern

// Rolling window of 6 versions (current + 5 stable)
onlyIncludeVersions: ["current", "0.30.0", "0.29.0", "0.28.0", "0.27.0", "0.26.0"]

// When 0.31.0 releases, becomes:
onlyIncludeVersions: ["current", "0.31.0", "0.30.0", "0.29.0", "0.28.0", "0.27.0"]
// 0.26.0 drops out - goes to archive branch

Archive Process

When a version drops out of onlyIncludeVersions:

• Gets moved to dedicated archive branch (see vcluster-docs-archiver skill)
• Gets own Netlify deployment
• Main branch dropdown links to archived version

Testing & Validation

Before PR:

# Verify changes
git diff docusaurus.config.js netlify.toml

# Check versions
cat vcluster_versions.json

# Verify CLI docs
ls vcluster_versioned_docs/version-0.XX.0/cli/*.md | wc -l

After PR Deployed:

# Run hurl tests
hurl --test --variable BASE_URL=https://deploy-preview-XXXX--vcluster-docs-site.netlify.app \
  hack/test-vcluster-0.XX.hurl

Troubleshooting

Issue: Version already exists

Solution: User already ran versioning command - proceed with config updates

Issue: CLI docs missing

Solution: Check if CLI generation script ran - see Notion doc

Issue: Build fails

Solution: User responsibility - they run npm run build

Issue: Hurl tests fail

Solution:

1. Check BASE_URL is correct Netlify preview
2. Verify netlify.toml redirect is correct
3. Check version numbers in test file match

Linear Issue Integration

When triggered by Linear issue (e.g., ENG-9160):

1. Extract version number from issue or ask user
2. Verify prerequisites completed
3. Execute workflow (Part 2)
4. Report checklist status
5. Remind user of their tasks

Example Output

After completing workflow, provide summary:

✅ vCluster 0.30.0 Release Configuration Complete

Files Updated:
- docusaurus.config.js (6 locations)
- netlify.toml (redirect updated)
- hack/test-vcluster-0.30.hurl (created)

My Tasks Complete (2-5):
✅ Updated banner
✅ Updated netlify redirect
✅ Verified CLI docs (93 files found)
✅ Created hurl test file

Your Tasks Remaining (1, 6-9):
⏳ Review enterprise/pro tags
⏳ Update support dates
⏳ Update compatibility matrix
⏳ Run build: npm run build
⏳ Run hurl tests (after PR deployed)

Ready to commit and push!

Quick Reference

Version pattern: 0.30.0 → label: v0.30 Files to modify: 4 files total (release day adds src/config/docsearch.js) Lines to change: ~10 locations across all files Time estimate: 2-3 minutes for AI tasks

Notes

• This skill is for vCluster only — Platform has separate release process
• Starting with v0.33, versioning happens at rc-1, not on release day
• The version is deployed hidden at rc-1, then exposed via config flip PR on release day
• Contributors use backport-v0.33 label for changes that must land in the upcoming release
• Always remove "Stable" label from previous version when adding new one
• Keep 5-6 versions in onlyIncludeVersions for build performance
• Hurl tests validate redirects work correctly
• User runs build — AI does not run npm commands

CRITICAL: Cross-Plugin Links to Platform

vCluster docs frequently link to Platform docs. These links can break when Platform releases a new version.

Why Cross-Plugin Links Break

1. Platform lastVersion change: When Platform releases (e.g., 4.5.0 → 4.6.0), /docs/platform/... routes to new version
2. Path restructuring: Platform may reorganize docs between versions
3. vCluster links resolve to Platform's lastVersion: All /platform/... links in vCluster docs point to current Platform version

Common Platform Path Changes to Watch

When Platform releases, check if vCluster docs have broken links to:

/platform/administer/monitoring/...  → /platform/maintenance/monitoring/...
/platform/install/advanced/air-gapped → /platform/install/air-gapped
/platform/administer/users-permissions/... → /platform/administer/authentication/...
/platform/api/authentication → /platform/administer/authentication/access-keys

Fixing vCluster→Platform Links

After Platform release, run Netlify build to find broken links, then fix:

# Update paths in all vCluster versioned docs
find vcluster vcluster_versioned_docs -name "*.mdx" \
  -exec sed -i 's|/platform/administer/monitoring/|/platform/maintenance/monitoring/|g' {} \;

find vcluster vcluster_versioned_docs -name "*.mdx" \
  -exec sed -i 's|/platform/install/advanced/air-gapped|/platform/install/air-gapped|g' {} \;

Version-Specific Platform Links

If vCluster docs link to Platform version that's no longer in onlyIncludeVersions:

<!-- WRONG - 4.3.0 not in Platform build anymore -->
[Templates](/platform/4.3.0/administer/templates/create-virtual-cluster-template)

<!-- CORRECT - use current Platform path -->
[Templates](/platform/administer/templates/create-templates)

Coordinating Releases

When both vCluster and Platform release simultaneously:

1. Platform changes lastVersion and may restructure paths
2. vCluster cross-plugin links need updating to match new Platform structure
3. Test vCluster→Platform links in Netlify preview before merging
