Exercise - Deploy Spring Boot application

This section guides you through deploying a Spring Boot application to Azure Container Apps. We cover packaging the application, setting up the Azure environment, and pushing the application to Azure Container Apps.

Setup

To sign in to the latest version of the Azure CLI, use the following steps, and follow the prompts to complete the authentication process:

1. Use the following command to sign in to the Azure CLI:

   • Bash
   • PowerShell

   az login
   

2. Use the following upgrade command to ensure you're running the latest version of the Azure CLI:

   • Bash
   • PowerShell

   az upgrade
   

Next, install or update the Azure Container Apps extension for the CLI, and register the Microsoft.App and Microsoft.OperationalInsights namespaces by using the following steps:

1. First, install or update the Azure Container Apps extension by using the following command or commands:

   • Bash
   • PowerShell

   az extension add --name containerapp --upgrade
   

2. Register the Microsoft.App and Microsoft.OperationalInsights namespaces by using the following commands:

   • Bash
   • PowerShell

   az provider register --namespace Microsoft.App
   az provider register --namespace Microsoft.OperationalInsights
   

Create environment variables

Define the environment variables needed throughout this article by using the following commands:

export RESOURCE_GROUP="petclinic-containerapps"
export LOCATION="canadacentral"
export ENVIRONMENT="env-petclinic-containerapps"
export APP_NAME="petclinic"

$Env:RESOURCE_GROUP = "petclinic-containerapps"
$Env:LOCATION = "canadacentral"
$Env:ENVIRONMENT = "env-petclinic-containerapps"
$Env:APP_NAME = "petclinic"

Locate the sample code

Navigate to the azure-container-apps-java-samples/spring-petclinic/spring-petclinic directory of the project.

Build and deploy the container app

Build and deploy your first Spring Boot app with the containerapp up command, which accomplishes the following tasks:

• Creates the resource group.
• Creates an Azure container registry.
• Builds the container image and pushes it to the registry.
• Creates the Container Apps environment with a Log Analytics workspace.
• Creates and deploys the container app using the built container image.

The containerapp up command uses the Dockerfile in the root of the repository to build the container image. Use the following command to build the container image. The .. (dot dot) tells the containerapp up command to run the Dockerfile in the parent folder.

az containerapp up \
    --resource-group $RESOURCE_GROUP\
    --name $APP_NAME \
    --location $LOCATION \
    --environment $ENVIRONMENT \
    --source ..

az containerapp up `
    --resource-group $RESOURCE_GROUP `
    --name $APP_NAME `
    --location $LOCATION `
    --environment $ENVIRONMENT `
    --source ..

Verify deployment

After your deployment is complete, you should see the following success message with the project endpoint printed in the console. You can open the URL to verify that your project deployed to Azure.

Container app created. Access your app at https://petclinic.wonderful

Your container app petclinic has been created and deployed! Congrats!

Browse to your container app at: http://petclinic.wonderful

Stream logs for your container with: az containerapp logs show -n petclinic -g petclinic-containerapps

See full output using: az containerapp show -n petclinic -g petclinic-containerapps
