Blend

Set up continuous deployment for Blendx standalone apps using GitHub Actions.

Prerequisites

Azure Container App already created and running
GitHub repository access for secrets configuration
Azure service principal credentials (or existing credentials from another deployment)

1. Get Required Credentials

Container Registry Credentials

# Get username (usually the registry name)
az acr credential show --name blendappcr --query username -o tsv

# Get password
az acr credential show --name blendappcr --query "passwords[0].value" -o tsv

2. GitHub Secrets Configuration

Go to your GitHub repository → Settings → Secrets and variables → Actions → New repository secret

Add the following secrets:

Secret Name	Description
`AZURE_CREDENTIALS`	Azure service principal JSON (see format below)
`CONTAINER_REGISTRY_USERNAME`	ACR username (usually `blendappcr`)
`CONTAINER_REGISTRY_PASSWORD`	ACR password from Step 1

AZURE_CREDENTIALS Format

{
  "clientSecret": "<client-secret>",
  "subscriptionId": "<subscription-id>",
  "tenantId": "<tenant-id>",
  "clientId": "<client-id>"
}

These values come from the service principal. If these secrets already exist from another deployment, you can reuse them.

3. GitHub Workflow Setup

Create the file .github/workflows/deploy-azure.yml:

name: Deploy to Azure Container Apps

on:
  push:
    branches: [main]
  workflow_dispatch:

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Set up Node.js
        uses: actions/setup-node@v4
        with:
          node-version: "20.x"

      - name: Install dependencies
        run: npm install

      - name: Azure Login
        uses: azure/login@v1
        with:
          creds: ${{ secrets.AZURE_CREDENTIALS }}

      - name: Build and push container image to registry
        uses: azure/container-apps-deploy-action@v1
        with:
          appSourcePath: ${{ github.workspace }}
          registryUrl: blendappcr.azurecr.io
          registryUsername: ${{ secrets.CONTAINER_REGISTRY_USERNAME }}
          registryPassword: ${{ secrets.CONTAINER_REGISTRY_PASSWORD }}
          containerAppName: blendx-app
          resourceGroup: BLEND.APP
          imageToBuild: blendappcr.azurecr.io/blendx-app:${{ github.sha }}
          dockerfilePath: Dockerfile

4. Deployment Process

Automatic Deployment

Push code to the main branch:

git add .
git commit -m "Your changes"
git push origin main

The GitHub Action will automatically trigger and deploy.

Manual Deployment

You can also trigger deployments manually from the Actions tab in GitHub using the "Run workflow" button.

Customization

Update these values in the workflow file for your specific app:

Value	Description
`containerAppName`	Your Azure Container App name
`resourceGroup`	Your Azure resource group
`imageToBuild`	Docker image name with your app name
`registryUrl`	Your Azure Container Registry URL

Set up CI/CD
