environment-deployment

name	environment-deployment
description	Generate, transfer, and consume environment-specific Azure, AKS, OSMO, ACR, and Azure ML deployment bundles. Use when: discovering deployed environment details; creating OSMO image manifests or platform values; preparing a HiL host; uploading or downloading deployment files through Azure Key Vault; or deploying with generated environment configuration.

Environment Deployment

Generate non-secret deployment details from Terraform desired state and read-only Azure, Kubernetes, and OSMO discovery. Store generated artifacts under the gitignored infrastructure/setup/generated/<environment>/ directory.

Goal

Produce a validated non-secret environment bundle or a host-bound HiL handoff whose target, ownership, transfer, and next operation are explicit. Keep discovery read-only and keep generated environment values outside tracked source.

Flow

1. Resolve the environment, desired-state sources, available read-only tools, and requested bundle consumers.
2. Verify target identities and generate only the required allowlisted artifacts under the gitignored environment directory.
3. Validate hashes, immutable references, file safety, and the absence of credentials before use.
4. Preview the selected deployment or, for HiL, publish the exact host-bound catalog to Key Vault and hand off to the local consumer.

Inputs

• Environment name and Terraform directory
• Existing isolated Kubernetes context when live cluster verification is available
• Optional isolated authenticated OSMO profile for read-only service verification
• Requested deployment consumers and explicit version overrides
• For HiL publication, the host identity, existing backend and pool, approved service URL, protected registry configuration, Key Vault name, and optional public VPN inputs

Safety Boundaries

Follow these rules for every environment bundle:

• Do not modify Azure resources, Kubernetes resources, OSMO configuration, or the active OSMO profile during discovery.
• Do not run terraform apply, kubectl apply, Helm upgrade/install, OSMO update/set/delete commands, or Azure create/update/delete commands while generating a bundle.
• Do not upload artifacts or publish credentials during read-only discovery.
• Do not write discovered values into tracked files, documentation, examples, tests, or source defaults.
• Do not replace instructional RFC1918 addresses or example resource shapes solely because they differ from the deployed environment.
• Do not include Terraform state, secret values, kubeconfig contents, OSMO profiles, tokens, registry credentials, VPN keys, certificates, or absolute local paths in a bundle.
• Use an isolated kubeconfig and explicit context. Verify the AKS resource ID before reading cluster state.
• Ask before changing an Azure CLI subscription or OSMO profile when the requested task is discovery only.
• Use existing protected password or token files for non-interactive login. Never request secrets through chat.

Bundle Layout

Create only the artifacts needed by the deployment:

infrastructure/setup/generated/<environment>/
├── deployment.json
├── osmo-platforms.yaml
├── osmo-images.json
└── azureml-instance-types.yaml

deployment.json is required. The other files are optional when the corresponding component is not deployed.

Use lowercase letters, numbers, and hyphens for <environment>. Keep artifact filenames stable because the Key Vault transfer scripts use this allowlist.

Prerequisites

Use every available discovery tool. Record unavailable tools and skipped checks in deployment.json.

Tool	Purpose	Required
Terraform	Read desired resources and node-pool configuration	Yes
Azure CLI	Verify Azure identity and live resource metadata	Yes
jq	Select explicit non-secret fields and write JSON	Yes
kubectl	Verify AKS nodes, labels, taints, GPU capacity, and OSMO endpoint	When AKS is reachable
osmo	Verify the authenticated service and available pools	When an isolated profile is supplied
Helm	Read the deployed OSMO image version and values	When OSMO is deployed

For private resources, connect to the VPN before live Azure, AKS, Key Vault, or OSMO checks.

Generate a Bundle

This is an agent-led discovery workflow, not a static checked-in generator. The agent executes the available read-only commands below, renders files from the current Terraform and live resource data, validates the result, and reports every skipped probe. Do not reuse artifacts from another environment.

1. Establish the target

Collect or infer:

• Environment name
• Terraform directory, normally infrastructure/terraform
• Isolated kubeconfig path, normally $HOME/.kube/physical-ai-toolchain/<aks-cluster>.yaml
• Explicit Kubernetes context
• Optional isolated OSMO profile directory
• Optional OSMO image version when OSMO is not deployed yet

Create infrastructure/setup/generated/<environment>/. Do not create a tracked placeholder in this directory.

2. Read Terraform desired state

Run terraform output -json from the Terraform directory. Select only explicit output fields; never copy raw output or state into the bundle.

Read these values when present:

Terraform output	Bundle use
resource_group	Resource group name and location
key_vault_name	Key Vault bundle transfer
aks_cluster	AKS name and resource ID
node_pools	GPU pool VM sizes, priority, labels, and taints
container_registry	ACR name and login server
storage_account	Storage account name
azureml_workspace	Azure ML workspace name
osmo_workload_identity	OSMO workload identity ID and Entra metadata

Fail when the resource group, Key Vault, or requested AKS/ACR values are missing. Do not infer names from naming conventions when Terraform exposes them.

3. Verify Azure

Use read-only Azure CLI calls:

1. Read the active account with az account show.
2. Confirm its subscription matches the subscription segment of the AKS resource ID.
3. Read the resource group with az group show.
4. Read AKS with az aks show and compare its normalized resource ID with Terraform.
5. Read ACR with az acr show and compare its name and login server with Terraform.
6. Read Key Vault metadata with az keyvault show; do not enumerate or read unrelated secret values.
7. Read osmo_workload_identity with az identity show --ids, and confirm its ID, client ID, and tenant ID match Terraform.

Stop on any identity or resource mismatch. Do not switch subscriptions silently.

4. Verify Kubernetes

When kubectl is available and AKS is reachable:

1. Use verify_existing_aks_kubeconfig before refreshing credentials.
2. Use connect_aks from scripts/lib/common.sh only when the user requested credential setup.
3. Otherwise require an existing isolated kubeconfig and use verify_kube_target.
4. Read nodes with an explicit kubeconfig and context.
5. For each Terraform GPU pool, compare:
   • agentpool label
   • node.kubernetes.io/instance-type label
   • Terraform node labels
   • Terraform taints
   • status.allocatable["nvidia.com/gpu"]
6. Read azureml/azureml-ingress-nginx-internal-lb and form http://<RFC1918-address> from its assigned ingress IP.

Scale-to-zero pools may have no live nodes. Generate their configuration from Terraform and record live capacity as unavailable instead of omitting the pool.

5. Verify OSMO

Do not run osmo login during discovery. If the caller supplies an isolated authenticated profile, set XDG_CONFIG_HOME to it and run read-only checks:

• osmo version
• osmo pool list --format-type json

When Helm is available, read the deployed OSMO release with the same isolated kubeconfig and context. Prefer global.osmoImageTag from deployed values for the image version. Fall back to OSMO_IMAGE_VERSION from infrastructure/setup/defaults.conf only for a new deployment.

Record whether OSMO and Helm verification succeeded. Do not copy profile data into the bundle.

6. Generate OSMO platform values

Generate osmo-platforms.yaml from node_pools.

For each GPU pool:

• Create one pod template with agentpool and node.kubernetes.io/instance-type selectors.
• Add Terraform node labels that constrain scheduling.
• Convert each Terraform taint into a matching Exists or Equal toleration.
• Add the nvidia.com/gpu NoSchedule toleration when the pool uses it.
• Set requests and limits to the literal OSMO Jinja value {{USER_GPU}}.
• Create a platform under services.configs.pools.default.platforms.
• Use a default GPU count no greater than verified per-node allocatable capacity. Use 1 when the pool is scaled to zero and capacity cannot be verified.
• Keep USER_CPU, USER_MEMORY, USER_STORAGE, and USER_SHM_SIZE as instructional defaults unless the user supplies workload requirements.

Use unique lowercase identifiers derived from the pool key. Preserve both braces in every OSMO Jinja expression.

7. Generate Azure ML InstanceTypes

Generate azureml-instance-types.yaml from the same pool data:

• Always include defaultinstancetype for CPU workloads.
• Create one GPU InstanceType per pool with the pool selector and constraining Terraform labels.
• Use gpuspot for the first spot pool and gpu for the first regular pool when those names are unambiguous; otherwise use gpu-<pool>.
• Set the GPU limit to a value no greater than verified per-node capacity. Use 1 for scale-to-zero pools without live capacity.
• Do not generate multi-GPU InstanceTypes without verified capacity or an explicit user requirement.

The deployment consumes this file through 02-deploy-azureml-extension.sh --instance-types-manifest.

8. Generate the immutable ACR image manifest

Generate osmo-images.json only when OSMO images are mirrored to ACR. Use this component allowlist:

• agent
• backend-listener
• backend-worker
• client
• delayed-job-monitor
• init-container
• logger
• router
• service
• web-ui
• worker

For each component, read the digest for osmo/<component>:<image-version> with az acr manifest show-metadata. Confirm the repository tag has writes and deletes disabled with az acr repository show. Fail if a component, digest, or immutability setting is missing.

Write this shape:

{
  "schema_version": 1,
  "registry": "<acr-name>",
  "login_server": "<acr-login-server>",
  "image_version": "<version>",
  "images": {
    "<component>": {
      "repository": "osmo/<component>",
      "digest": "sha256:<64-lowercase-hex>"
    }
  }
}

9. Generate deployment metadata

Write deployment.json last. Use relative artifact filenames and SHA-256 digests. Include:

{
  "schema_version": 1,
  "environment": "<environment>",
  "generated_at": "<UTC-RFC3339>",
  "subscription_id": "<subscription-id>",
  "tenant_id": "<tenant-id>",
  "resource_group": "<resource-group>",
  "location": "<azure-region>",
  "key_vault_name": "<key-vault>",
  "aks_cluster": "<aks-cluster>",
  "aks_resource_id": "<aks-resource-id>",
  "acr_name": "<acr-name-or-empty>",
  "acr_login_server": "<login-server-or-empty>",
  "azureml_workspace": "<workspace-or-empty>",
  "storage_account": "<storage-account-or-empty>"
   
   
   
   
   
     
     
     
     
  
   
        
        
        
  
   
     
     
     
     
     
  

Set osmo_workflow_data_uri from the configured OSMO workflow_data.credential.endpoint, not a naming convention. It must match azure://<account>/<container>/workflows/data. Omit optional artifact entries when their files do not exist. Set unavailable verification tools to false; do not claim checks that did not run.

10. Validate

Before using or uploading the bundle:

• Confirm every artifact is a regular non-symlink file.
• Confirm deployment.json matches the active subscription, Terraform resource group, Key Vault, and AKS resource ID.
• Confirm osmo_workflow_data_uri is the configured Azure workflow-data endpoint and osmo_workload_identity matches Terraform and Azure identity metadata.
• Confirm artifact paths are relative filenames without ...
• Recalculate and compare every artifact SHA-256.
• Validate osmo-images.json against verify_acr_image_manifest when ACR is used.
• Run kubectl apply --dry-run=client -f for the Azure ML InstanceTypes when kubectl is available.
• Search the bundle for private keys, bearer tokens, password fields, Docker auth, kubeconfig client data, and absolute home-directory paths. Stop if any are found.
• Confirm git check-ignore infrastructure/setup/generated/<environment>/deployment.json succeeds.

Use the Bundle

Pass generated artifacts explicitly; do not copy them back into tracked values/ or manifests/ directories.

Deployment	Generated argument
Azure ML extension	02-deploy-azureml-extension.sh --instance-types-manifest <bundle>/azureml-instance-types.yaml
OSMO control plane	03-deploy-osmo.sh --platform-values <bundle>/osmo-platforms.yaml --use-acr --image-manifest <bundle>/osmo-images.json

Read the image version, service URL, AKS resource ID, and resource names from deployment.json. Run each deployment script with --config-preview first. Deployment scripts may change Azure or Kubernetes resources; obtain user confirmation before continuing from discovery into deployment.

Transfer a Generic Non-Secret Bundle

Upload the allowlisted bundle from the trusted deployment host:

infrastructure/setup/upload-environment-bundle.sh --environment <environment> --config-preview
infrastructure/setup/upload-environment-bundle.sh --environment <environment>

The uploader requires Key Vault secret write permission. It never changes RBAC.

Each UTF-8 artifact must be no larger than 24,000 bytes. Omit an optional file and its deployment.json artifact entry together. Existing Key Vault versions may remain, but consumers follow the current deployment.json allowlist.

Do not run concurrent uploads for the same environment. The uploader publishes artifacts first and deployment.json last so consumers either receive a coherent bundle or fail its digest checks.

For a generic, non-HiL consumer, authenticate to Azure, connect to the private network or VPN, and download the bundle:

infrastructure/setup/download-environment-bundle.sh --environment <environment> --resource-group <resource-group> --config-preview
infrastructure/setup/download-environment-bundle.sh --environment <environment> --resource-group <resource-group>

The downloader requires the Key Vault Secrets User role and private endpoint connectivity when the vault is private.

Configure local clients from the protected bundle:

infrastructure/setup/connect-environment.sh --environment <environment> --config-preview
infrastructure/setup/connect-environment.sh --environment <environment>

Use --osmo-method dev --osmo-username <user> only for an explicitly approved development deployment. Use protected files with --password-file or --token-file for service authentication.

download-environment-bundle.sh and connect-environment.sh remain generic non-HiL utilities. They do not retrieve or configure host-bound HiL credentials.

Prepare and Connect an Ubuntu HiL Host

Complete this journey when an existing OSMO backend and pool are ready: the environment owner publishes the generic non-secret bundle separately from the host-bound protected inputs, then the Ubuntu consumer connects only its owned local K3s target with the catalog-bound artifacts.

Publish Host-Bound Inputs

The environment owner runs infrastructure/setup/04-prepare-osmo-hil-node.sh after verifying the existing OSMO backend and pool. Supply the generated bundle, approved service URL, existing backend and pool, protected OSMO profile, pull-only registry configuration, and token expiry. The script publishes the generic bundle and the exact host-bound catalog separately, writing the catalog last.

Key Vault is the only scripted protected-artifact transfer. Before publication, the environment owner manually creates the exact secret resources and grants the Ubuntu identity data-plane access to each named inbound secret only. Use Key Vault Secrets User for inbound secrets and Key Vault Secrets Officer only for the host-specific CSR secret. Verify that the Ubuntu identity has no direct or inherited vault-wide data-plane role.

Key Vault networking and RBAC are manual environment-owner actions. The publisher does not assign roles, modify Key Vault networking, or make a private vault reachable. Complete any bounded network-access window and restore private-only access before the consumer continues.

The publisher reuses the exact catalog-pinned OSMO token and token-metadata secret versions when they are valid and unexpired. --renew-token forces a new issuance. An absent catalog or valid expired token metadata issues a new token. Stop on a malformed or inaccessible catalog, or a token-metadata binding or digest mismatch. The publisher does not delete token versions.

Manual SCP is outside this repository HiL flow. An operator may use it only as an out-of-band procedure that does not invoke repository HiL publisher, VPN, or consumer scripts and does not use retired transfer arguments.

Connect the Ubuntu Consumer

After the Ubuntu host and any required VPN are ready, run the consumer boundary:

data-pipeline/setup/hil/02-connect-osmo-backend.sh \
  --environment <environment> \
  --host-name <host> \
  --tenant-id <tenant-id> \
  --subscription <subscription-id> \
  --vault-name <vault>

The consumer retrieves the catalog and declared artifacts from Key Vault. It validates catalog structure, artifact digests, token metadata, token digest, backend binding, and expiry before any Kubernetes mutation. A Key Vault access, network, target, catalog, or integrity failure stops the run.

The consumer validates the exact catalog-bound inputs and changes only the owned local K3s target. It does not administer Azure resources, AKS, Key Vault networking or RBAC, or remote OSMO desired state. Do not use download-environment-bundle.sh or connect-environment.sh as the Ubuntu HiL path.

Success Criteria

• Generated bundle files contain only the approved non-secret fields and remain under the gitignored environment directory.
• Every available read-only target check passes or is recorded as unavailable without a false verification claim.
• Deployment consumers receive explicit validated artifact paths instead of copied tracked values.
• A HiL publication uses Key Vault, preserves exact catalog-pinned artifact versions, and publishes the catalog last.
• No discovery action mutates Azure, Kubernetes, OSMO, Key Vault, or a client profile.

Stop Rules

• Stop when Terraform, Azure, AKS, ACR, Key Vault, or OSMO identity does not match the selected environment.
• Stop when a generated artifact contains a credential, private key, kubeconfig, profile, absolute home path, or unverified mutable reference.
• Stop before deployment, publication, role assignment, network change, or credential issuance unless the caller requested that separate action and its owner prerequisites are satisfied.
• Stop the Key Vault path on access, network, target, catalog, token, or integrity failure.

Handoff

Return the generated bundle path, validation results, unavailable checks, and the exact next preview command. For HiL preparation, identify the trusted Key Vault publisher command, the local consumer command, and any environment-owner RBAC or network checkpoint that remains.
