azd-deployment

Azure Developer CLI (azd) Container Apps Deployment

Deploy containerized frontend + backend applications to Azure Container Apps with remote builds, managed identity, and idempotent infrastructure.

Quick Start

# Initialize and deploy
azd auth login
azd init                    # Creates azure.yaml and .azure/ folder
azd env new <env-name>      # Create environment (dev, staging, prod)
azd up                      # Provision infra + build + deploy

azure.yaml Configuration

Minimal Configuration

name: azd-deployment
services:
  backend:
    project: ./​src/​backend
    language: python
    host: containerapp
    docker:
      path: ./​Dockerfile
      remoteBuild: true

Full Configuration with Hooks

name: azd-deployment
metadata:
  template: [email protected]

infra:
  provider: bicep
  path: ./​infra

azure:
  location: eastus2

services:
  frontend:
    project: ./​src/​frontend
    language: ts
    host: containerapp
    docker:
      path: ./​Dockerfile
      context: .
      remoteBuild: true

  backend:
    project: ./​src/​backend
    language: python
    host: containerapp
    docker:
      path: ./​Dockerfile
      context: .
      remoteBuild: true

hooks:
  preprovision:
    shell: sh
    run: |
      echo "Before provisioning..."
      
  postprovision:
    shell: sh
    run: |
      echo "After provisioning - set up RBAC, etc."
      
  postdeploy:
    shell: sh

      echo "Frontend: ${SERVICE_FRONTEND_URI}"
      echo "Backend: ${SERVICE_BACKEND_URI}"

Key azure.yaml Options

Environment Variables Flow

Three-Level Configuration

1. Local .env - For local development only
2. .azure/<env>/​.env - azd-managed, auto-populated from Bicep outputs
3. main.parameters.json - Maps env vars to Bicep parameters

Parameter Injection Pattern

// infra/​main.parameters.json
{
  "parameters": {
    "environmentName": { "value": "${AZURE_ENV_NAME}" },
    "location": { "value": "${AZURE_LOCATION=eastus2}" },
    "azureOpenAiEndpoint": { "value": "${AZURE_OPENAI_ENDPOINT}" }
  }
}

Syntax: ${VAR_NAME} or ${VAR_NAME=default_value}

Setting Environment Variables

# Set for current environment
azd env set AZURE_OPENAI_ENDPOINT "https://my-openai.openai.azure.com"
azd env set AZURE_SEARCH_ENDPOINT "https://my-search.search.windows.net"

# Set during init
azd env new prod
azd env set AZURE_OPENAI_ENDPOINT "..." 

Bicep Output → Environment Variable

// In main.bicep - outputs auto-populate .azure/<env>/​.env
output SERVICE_FRONTEND_URI string = frontend.outputs.uri
output SERVICE_BACKEND_URI string = backend.outputs.uri
output BACKEND_PRINCIPAL_ID string = backend.outputs.principalId

Idempotent Deployments

Why azd up is Idempotent

1. Bicep is declarative - Resources reconcile to desired state
2. Remote builds tag uniquely - Image tags include deployment timestamp
3. ACR reuses layers - Only changed layers upload

Preserving Manual Changes

Custom domains added via Portal can be lost on redeploy. Preserve with hooks:

hooks:
  preprovision:
    shell: sh
    run: |
      # Save custom domains before provision
      if az containerapp show --name "$FRONTEND_NAME" -g "$RG" &>/​dev/​null; then
        az containerapp show --name "$FRONTEND_NAME" -g "$RG" \
          --query "properties.configuration.ingress.customDomains" \
          -o json > /​tmp/​domains.json
      fi

  postprovision:
    shell: sh
    run: |
      # Verify/​restore custom domains
      if [ -f /​tmp/​domains.json ]; then
        echo "Saved domains: $(cat /​tmp/​domains.json)"
      fi

Handling Existing Resources

// Reference existing ACR (don't recreate)
resource containerRegistry 'Microsoft.ContainerRegistry/​registries@2023-07-01' existing = {
  name: containerRegistryName
}

// Set customDomains to null to preserve Portal-added domains
customDomains: empty(customDomainsParam) ? null : customDomainsParam

Container App Service Discovery

Internal HTTP routing between Container Apps in same environment:

// Backend reference in frontend env vars
env: [
  {
    name: 'BACKEND_URL'
    value: 'http://ca-backend-${resourceToken}'  // Internal DNS
  }
]

Frontend nginx proxies to internal URL:

location /​api {
    proxy_pass $BACKEND_URL;
}

Managed Identity & RBAC

Enable System-Assigned Identity

resource containerApp 'Microsoft.App/​containerApps@2024-03-01' = {
  identity: {
    type: 'SystemAssigned'
  }
}

output principalId string = containerApp.identity.principalId

Post-Provision RBAC Assignment

hooks:
  postprovision:
    shell: sh
    run: |
      PRINCIPAL_ID="${BACKEND_PRINCIPAL_ID}"
      
      # Azure OpenAI access
      az role assignment create \
        --assignee-object-id "$PRINCIPAL_ID" \
        --assignee-principal-type ServicePrincipal \
        --role "Cognitive Services OpenAI User" \
        --scope "$OPENAI_RESOURCE_ID" 2>/​dev/​null || true
      
      # Azure AI Search access
      az role assignment create \
        --assignee-object-id "$PRINCIPAL_ID" \
        --role "Search Index Data Reader" \
        --scope "$SEARCH_RESOURCE_ID" 2>/​dev/​null || true

Common Commands

# Environment management
azd env list                        # List environments
azd env select <name>               # Switch environment
azd env get-values                  # Show all env vars
azd env set KEY value               # Set variable

# Deployment
azd up                              # Full provision + deploy
azd provision                       # Infrastructure only
azd deploy                          # Code deployment only
azd deploy --service backend        # Deploy single service

# Debugging
azd show                            # Show project status
az containerapp logs show -n <app> -g <rg> --follow  # Stream logs

• Troubleshooting: See references/​troubleshooting.md for common issues
• azure.yaml schema: See references/​azure-yaml-schema.md for full options

Critical Reminders

1. Always use remoteBuild: true - Local builds fail on M1/​ARM Macs deploying to AMD64
2. Bicep outputs auto-populate .azure/<env>/​.env - Don't manually edit
3. Use azd env set for secrets - Not main.parameters.json defaults
4. Service tags (azd-service-name) - Required for azd to find Container Apps
5. || true in hooks - Prevent RBAC "already exists" errors from failing deploy

When to Use

This skill is applicable to execute the workflow or actions described in the overview.

<!-- AGI-INTEGRATION-START -->

AGI Framework Integration

Adapted for @techwavedev/​agi-agent-kit Original source: antigravity-awesome-skills

Memory-First Protocol

Retrieve prior deployment configurations, rollback procedures, and incident post-mortems. Avoid re-discovering infrastructure patterns.

# Check for prior infrastructure context before starting
python3 execution/​memory_manager.py auto --query "deployment configuration and patterns for Azd Deployment"

Storing Results

After completing work, store infrastructure decisions for future sessions:

python3 execution/​memory_manager.py store \
  --content "Deployment pipeline: configured blue-green deployment with health checks on port 8080" \
  --type technical --project <project> \
  --tags azd-deployment devops

Multi-Agent Collaboration

Broadcast deployment changes so frontend and backend agents update their configurations accordingly.

python3 execution/​cross_agent_context.py store \
  --agent "<your-agent>" \
  --action "Deployed infrastructure changes — updated CI/​CD pipeline with new health check endpoints" \
  --project <project>

Playbook Integration

Use the ship-saas-mvp or full-stack-deploy playbook to sequence this skill with testing, documentation, and deployment verification.
