Java on Azure Container Apps with Dapr sample

Dapr (Distributed Application Runtime) is a runtime that helps you build resilient stateless and stateful microservices. This repository includes a Java-based Dapr application which is deployed to Azure Container Apps via a Bicep template.

Running locally:

1. Initialize Dapr:

   dapr init
   

2. Build the Java packages:

   ./mvnw clean package
   

3. Run the Web API:

   dapr run --components-path ./webapi/components --app-id webapi --app-port 3000 -- java -jar webapi/target/webapi-0.0.1-SNAPSHOT.jar --server.port=3000
   

4. Run the Web App:

   dapr run --app-id webapp --app-port 8080 -- java -jar webapp/target/webapp-0.0.1-SNAPSHOT.jar --server.port=8080
   

Deploy to Azure Container Apps

1. Create a private container registry using the Azure CLI

2. Build containers images:

   docker build -t <login-server>/java-app/webapi:v1 webapi
   docker build -t <login-server>/java-app/webapp:v1 webapp
   

3. Push container images to your Container Registry:

   docker push <login-server>/java-app/webapi:v1
   docker push <login-server>/java-app/webapp:v1
   

4. Set required environment variables:

   RESOURCE_GROUP="my-containerapps"
   LOCATION="eastus2"
   

5. Create a resource group:

   az group create \
       --name $RESOURCE_GROUP \
       --location "$LOCATION"
   

6. Deploy:

   az deployment group create \
   --resource-group "$RESOURCE_GROUP" \
   --template-file ./infra/main.bicep \
   --parameters \
       registry_server="<registry_server>" \
       registry_username="<registry_username>" \
       registry_password="<registry_password>"
