Azure Pipelines: PR Preview Environments

Deploy preview environments for pull requests and clean up when they close.

azure-pipelines.yml
 
trigger:
  - main

pr:
  - main

pool:
  vmImage: ubuntu-latest

steps:
  - task: NodeTool@0
    inputs:
      versionSpec: "20.x"
    displayName: "Install Node.js"

  - script: npm install
    displayName: "Install dependencies"

  - script: |
      set -o pipefail
      npx zuplo deploy --api-key $(ZUPLO_API_KEY) 2>&1 | tee ./DEPLOYMENT_STDOUT
    displayName: "Deploy to Zuplo"

  - script: |
      DEPLOYMENT_URL=$(grep -oP 'Deployed to \K(https://[^ ]+)' ./DEPLOYMENT_STDOUT)
      echo "##vso[task.setvariable variable=DEPLOYMENT_URL]$DEPLOYMENT_URL"
      npx zuplo test --endpoint "$DEPLOYMENT_URL"
    displayName: "Run tests"

  - script: |
      npx zuplo delete --url $(DEPLOYMENT_URL) --api-key $(ZUPLO_API_KEY) --wait
    displayName: "Delete environment"
    condition: eq(variables['Build.Reason'], 'PullRequest')

The cleanup step only runs for pull requests, deleting the preview environment after tests pass.
