Migrate workshop from Azure Spring Apps to Azure Container Apps

[Copilot]

Azure Spring Apps is deprecated. Workshop migrated to Azure Container Apps platform.

Platform Changes

Deployment Model

• JAR artifact uploads → Multi-stage Docker containers
• az spring app create/deploy → az containerapp create/up/update
• Managed platform → Serverless container platform

Spring Cloud Infrastructure

• Config Server: Managed service → Standalone container (hyness/spring-cloud-config-server)
• Service Discovery: Managed registry → Internal DNS resolution (http://service-name)
• Gateway: Registry-based routing → Direct URL routing

Operations

• Blue/Green: Deployment slots → Container App revisions with traffic splitting
• Monitoring: AppPlatformLogsforSpring → ContainerAppConsoleLogs_CL
• CI/CD: azure/spring-cloud-deploy@v1 → az acr build + az containerapp update

Example Changes

Before (Azure Spring Apps):

az spring app create -n weather-service --runtime-version Java_17
az spring app deploy -n weather-service --artifact-path target/demo.jar

After (Azure Container Apps):

# Dockerfile added for containerization
az containerapp up \
    --name weather-service \
    --environment $AZ_CONTAINERAPP_ENV \
    --source . \
    --target-port 8080 \
    --ingress internal

Scope

• 17 documentation sections updated
• 3 Dockerfiles added (city-service, weather-service, gateway)
• Gateway routing simplified from service discovery to direct URLs
• Database connections (Cosmos DB, MySQL) unchanged
• All az spring commands (21+) replaced with az containerapp equivalents
