06 - CI/CD (Flex Consumption)¶

Automate build and deployment with GitHub Actions and environment gates.

Prerequisites¶

What You'll Build¶

You will create a GitHub Actions workflow for Flex Consumption deployment and confirm release health by invoking the deployed function.

Steps¶

Step 1 - Set variables (if not already set)¶

export RG="rg-func-node-flex-demo"
export APP_NAME="<your-function-app-name>"

Step 2 - Create the GitHub Actions workflow¶

Save the following as .github/workflows/deploy-node-flex.yml:

name: deploy-node-functions-flex
on:
  push:
    branches: [ main ]
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
      - run: npm ci
        working-directory: apps/nodejs
      - run: npm test --if-present
        working-directory: apps/nodejs
      - uses: Azure/functions-action@v1
        with:
          app-name: ${{ secrets.APP_NAME }}
          sku: flexconsumption
          package: 'apps/nodejs'
          remote-build: true
          publish-profile: ${{ secrets.AZURE_FUNCTIONAPP_PUBLISH_PROFILE }}

Step 3 - Store secrets in GitHub¶

1. Download the publish profile:

   az functionapp deployment list-publishing-profiles \
     --name "$APP_NAME" \
     --resource-group "$RG" \
     --xml
   

2. In your GitHub repository, go to Settings → Secrets and variables → Actions

3. Add the following secrets:
   • APP_NAME: Your function app name
   • AZURE_FUNCTIONAPP_PUBLISH_PROFILE: Paste the entire XML output

Step 4 - Validate release¶

After pushing to trigger the workflow, verify the deployment:

curl --request GET "https://$APP_NAME.azurewebsites.net/api/health"

Step 5 - Review Flex Consumption-specific notes¶

• Flex Consumption does not support Kudu/SCM for log streaming.
• Use Application Insights or HTTP verification instead.
• Use long-form CLI flags for maintainable runbooks.

Verification¶

After a successful GitHub Actions run, verify the function responds:

curl --request GET "https://$APP_NAME.azurewebsites.net/api/health"

Expected response:

{"status":"healthy","timestamp":"2026-04-10T00:30:00.000Z","version":"1.0.0"}

You can also verify via Application Insights:

az monitor app-insights query \
  --app "$APP_NAME" \
  --resource-group "$RG" \
  --analytics-query "requests | where name == 'health' | take 5" \
  --output json
