This repository contains artifacts to help you get started running Tomcat applications on Azure container platforms, such as the Azure Kubernetes Service (AKS). It is intended to accompany the Tomcat to AKS Migration guide.

We provide a WAR build of Spring Pet Clinic in ROOT.war as a sample application. By following the steps below, you can see this QuickStart in action without the need to provide your own applciation or to make any modifications.

For running locally:

• Docker CLI

For running on Azure:

• Azure CLI
• An Azure subscription.

If you have Docker CLI installed locally, you can run this QuickStart on your machine:

1. Clone the repository and navigate into the root of the repository:

   git clone https://github.com/Azure/tomcat-container-quickstart.git
   cd tomcat-container-quickstart

2. Build the docker image:

   docker build . -t tomcat

3. Run the image:

   docker run -p8080:8080 -d tomcat

   Once the container is running, navigate to http://localhost:8080 in your favorite browser. You should see the Petclinic application come up.

Alternatively, you can build and test the image entirely on Azure. These steps can be performed from Azure CloudShell or from any machine with Azure CLI installed.

1. Create an Azure Container Registry. Be sure to enable the admin user.

2. Clone the repository and navigate into the root of the repository:

    git clone https://github.com/Azure/tomcat-container-quickstart.git
    cd tomcat-container-quickstart

1. Once the Azure Container Registry instance is created, run the following command, where ${REGISTRY_NAME} is the name of the Azure Container Registry you just created:

   az acr build -r ${REGISTRY_NAME} -t "${REGISTRY_NAME}.azurecr.io/tomcat" .

   The Azure Container Registry will now build the docker image on its own server.

2. Once the image build has completed, run the following command. It will deploy the image onto an Azure Container Instance. ${RESOURCE_GROUP} should be the name of a resource group in your azure subscription. ${REGISTRY_NAME} should be the same as above

   az container create -g ${RESOURCE_GROUP} -n ${REGISTRY_NAME} \
     --image "${REGISTRY_NAME}.azurecr.io/tomcat"  \
     --registry-password "$(az acr credential show -n $REGISTRY_NAME --query "passwords[0].value" -o tsv)" \
     --registry-username "${REGISTRY_NAME}" \
     --ip-address Public \
     --ports 8080 \
     --query "ipAddress.ip"

   When the command completes, it will display an IP address. Navigate to http://<The IP Address>:8080 in your browser, and you should see the home page of the deployed web application.

   To terminate the container instance, run

   az container delete -g ${RESOURCE_GROUP} -n ${REGISTRY_NAME} --yes
