📊 Builder API

Fluent Interface Chain

AppContainerBuilder(args)
  .withEnvironment(props?)          // Configure managed environment
  .withContainer(props)             // Add container (repeatable)
  .withIngress(props)               // Configure ingress
  .withScale(props)                 // Configure auto-scaling
  .withSecrets(secrets)             // Add secrets (repeatable)
  .withRegistry(registry)           // Configure registry (repeatable)
  .withDapr(props)                  // Enable Dapr
  .withIdentity(type)               // Configure managed identity
  .lock()                           // Prevent deletion
  .build()                          // Create resources

🔐 RBAC Roles

Environment Role	Azure Roles Assigned
ReadOnly	ContainerApp Reader
Contributor	Azure ContainerApps Session Executor
Admin	Contributor

📝 Naming Convention

• Container App: {prefix}-{name}-{org}-{region}-capp
• Environment: {prefix}-{name}-env-{org}-{region}-capp-env

Examples:

• Dev: dev-myapp-myorg-seau-capp
• Prod: prd-myapp-myorg-seau-capp

📖 Usage Example

import { AppContainerBuilder, ResourceBuilder } from '@drunk-pulumi/azure';

// Create foundation
const foundation = await ResourceBuilder('myapp')
  .createRG()
  .createVault()
  .createEnvUID()
  .build();

// Deploy container app
const app = AppContainerBuilder({
  name: 'api',
  group: foundation.group!,
  vaultInfo: foundation.vaultInfo,
  envUIDInfo: foundation.envUIDInfo,
  envRoles: foundation.envRoles
})
  .withEnvironment({
    workloadProfileType: 'Consumption',
    zoneRedundant: true
  })
  .withContainer({
    image: 'myregistry.azurecr.io/api:latest',
    resources: { cpu: 1.0, memory: '2Gi' },
    env: [
      { name: 'NODE_ENV', value: 'production' }
    ],
    probes: [{
      type: 'Liveness',
      httpGet: { path: '/health', port: 8080 }
    }]
  })
  .withIngress({
    external: true,
    targetPort: 8080,
    transport: 'http2'
  })
  .withScale({
    minReplicas: 2,
    maxReplicas: 20,
    rules: [{
      name: 'http-scaling',
      http: { metadata: { concurrentRequests: '50' }}
    }]
  })
  .withIdentity('SystemAssigned,UserAssigned')
  .lock()
  .build();

🔍 Type Safety

The builder uses progressive interface narrowing:

1. IAppContainerEnvironmentBuilder - Initial state
2. IAppContainerBuilder - After withEnvironment()
3. All methods return IAppContainerBuilder for chaining
4. build() returns ResourceInfo

🎓 Best Practices Implemented

1. ✅ Automatic naming with environment/region awareness
2. ✅ Security by default (managed identities recommended)
3. ✅ Production defaults (zone redundancy in prod)
4. ✅ Resource locking support
5. ✅ RBAC integration
6. ✅ Key Vault integration for secrets
7. ✅ Health probe support
8. ✅ Auto-scaling configuration
9. ✅ VNet integration support
10. ✅ Comprehensive error messages
