STACKIT Azure DevOps Service Connection Extension

Azure DevOps extension to authenticate with STACKIT cloud platform using either Workload Identity Federation (WIF) or Key Flow (JSON credentials). This extension provides a secure service connection type and an authentication task that sets up environment variables and can perform CLI login when explicitly enabled.

Features

• ✅ Service Connection Type: Secure credential storage for STACKIT authentication
• ✅ WIF Authentication: Workload Identity Federation - minimal setup, just provide service account name
• ✅ OIDC Token Exchange: Automatic Azure DevOps OIDC token → STACKIT access token conversion
• ✅ Environment Setup: Sets required environment variables for STACKIT SDK
• ✅ Secret Masking: Access tokens masked in pipeline logs
• ✅ Linux Support: Task runs on Linux agents only

Authentication Methods

Important: Choose Exactly One

When creating a STACKIT service connection, you must provide exactly one authentication method:

Configuration Rules

• ✅ Do this: Fill EITHER the Service Account Name field OR the Credentials JSON field
• ❌ Don't do this: Leave both fields empty
• ❌ Don't do this: Fill both fields with values

If you misconfigure the connection (empty or both filled), the stackit-authenticate task will fail with a clear error message telling you which field to fix.

Usage

Creating a Service Connection

WIF (Workload Identity Federation)

1. In Azure DevOps, go to Project Settings → Service connections
2. Click New service connection → STACKIT
3. Choose WIF authentication scheme
4. Enter:
   • Service Account Name: Name of your STACKIT service account
5. Test the connection
6. Save

Key Flow (JSON Credentials)

1. In Azure DevOps, go to Project Settings → Service connections
2. Click New service connection → STACKIT
3. Choose Generic authentication scheme
4. Paste the full JSON credentials from your STACKIT service account
5. Test the connection (optional)
6. Save

Using in Pipelines

Example: WIF Authentication

trigger:
  - main

pool:
  vmImage: 'ubuntu-latest'

steps:
  - task: StackitAuthenticate@1
    inputs:
      serviceConnection: 'My STACKIT Connection (WIF)'
    displayName: 'Authenticate with STACKIT (WIF)'

  - script: |
      echo "Service Account: $STACKIT_SERVICE_ACCOUNT_EMAIL"
    displayName: 'Verify STACKIT Authentication'

Example: Key Flow Authentication

trigger:
  - main

pool:
  vmImage: 'ubuntu-latest'

steps:
  - task: StackitAuthenticate@1
    inputs:
      serviceConnection: 'My STACKIT Connection (Key Flow)'
    displayName: 'Authenticate with STACKIT (Key Flow)'

  - script: |
      # For Key Flow, credentials are available via STACKIT_SERVICE_ACCOUNT_KEY_PATH
      stackit auth activate-service-account
      stackit projects list
    displayName: 'List STACKIT Projects'

Task Inputs

Environment Variables Set by Task

Requirements

• Azure DevOps Agent with Node.js 20+ (standard on modern agents)
• STACKIT CLI installed on the agent (stackit command available)
• For Key Flow: Valid STACKIT service account credentials in JSON format
• For WIF: Configured Workload Identity Federation in STACKIT

Publishing

Prerequisites

• GitHub account with access to this repository
• Azure DevOps Marketplace Publisher account
• Marketplace Personal Access Token (PAT)

CI/CD Workflows

• ci.yml: Build, test, package, and upload VSIX artifact on push/PR
• release.yml: Build, test, package, publish (tag/manual), and attach VSIX to GitHub Release

Automatic Publishing (CI/CD)

1. Set GitHub Secrets (in repository settings):

   • MARKETPLACE_PAT: Your Azure DevOps Marketplace Personal Access Token

2. Publish via GitHub Actions (release.yml):

   • Push a tag: git tag v1.0.1 && git push --tags
   • Or merge to main with version bump in vss-extension.json
   • GitHub Actions will automatically build, test, and publish

Manual Publishing

# Build and package
npm run build
npm run package

# Publish to marketplace
npm run package:publish

Troubleshooting

Service Connection fails to save

• Ensure you're using the correct authentication scheme (WIF vs Key Flow)
• For Key Flow: validate JSON format is correct (copy directly from STACKIT UI)
• Check that STACKIT API URL is reachable

Task fails with "STACKIT CLI not found"

• Ensure STACKIT CLI (stackit command) is installed on the agent
• Add CLI installation step before authentication task if needed

Variables not available in next steps

• Verify the task ran successfully (check logs)
• Use explicit environment variable reference in YAML if needed:

  - task: StackitAuthenticate@1
    name: StackitAuth
  - script: echo $(STACKIT_SERVICE_ACCOUNT_EMAIL)
