06 - CI/CD (Consumption)

Automate build and deployment with GitHub Actions.

Prerequisites

Tool Version Purpose
Node.js 20+ Local runtime and package execution
Azure Functions Core Tools v4 Local host and publishing
Azure CLI 2.61+ Azure resource provisioning and management
GitHub repository — Source code hosting with Actions enabled

Consumption plan basics

Consumption (Y1) is serverless with scale-to-zero, up to 200 instances, 1.5 GB memory per instance, and a default 5-minute timeout (max 10 minutes).

What You'll Build

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

Infrastructure Context

Plan: Consumption (Y1) | Network: Public internet only | VNet: ❌ Not supported

GitHub Actions deploys to the Consumption function app via publish profile authentication.

Steps

Step 1 - Set variables (if not already set)

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

Step 2 - Create the GitHub Actions workflow

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

name: deploy-node-functions
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 }}
          package: 'apps/nodejs'
          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 (e.g., func-ndcons-04100010)
    • AZURE_FUNCTIONAPP_PUBLISH_PROFILE: Paste the entire XML output from the command above

Step 4 - Validate release

After pushing to trigger the workflow, verify the deployment by invoking the function:

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

az functionapp log tail does not exist

The command az functionapp log tail is not a valid Azure CLI command as of CLI version 2.83.0. The az webapp log tail command exists but returns HTTP 404 for Consumption plan function apps because Consumption does not support persistent log streaming.

Alternatives for viewing logs:

  • Application Insights queries: az monitor app-insights query --app $APP_NAME-ai --analytics-query "traces | take 20"
  • Azure Portal: Navigate to Function App → Monitor → Log stream
  • Live Metrics: Application Insights → Live Metrics (real-time)

Step 5 - Review Consumption-specific notes

  • Use --consumption-plan-location for app creation and expect cold starts under idle periods.
  • Use long-form CLI flags for maintainable runbooks.
  • Keep FUNCTIONS_WORKER_RUNTIME=node across all environments.

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