Deploying Spring Boot to Azure VM

This is a simple project to see how to deploy a Spring Boot project in Azure Virtual Machine using maven.

Web Application

This web application exposes a single endpoint that shows the host machine name and its IP address.

GET /hello

Hello 87da7dce8b2f/172.16.0.4

Azure CLI

$ az login

$ az ad sp create-for-rbac --name "app-name" --password "password"

You should receive this as response:

{
    "appId": "aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa",
    "displayName": "app-name",
    "name": "http://app-name",
    "password": "password",
    "tenant": "tttttttt-tttt-tttt-tttt-tttttttttttt"
}

Maven Settings.xml Configuration

Now we configure Azure service principal authentication settings in our Maven settings.xml, with the help of the following section, under :

<server>
    <id>azure-auth</id>
    <configuration>
        <client>aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa</client>
        <tenant>tttttttt-tttt-tttt-tttt-tttttttttttt</tenant>
        <key>password</key>
        <environment>AZURE</environment>
    </configuration>
</server>

Maven Configuration

In pom.xml file add this plugin configuration to plugins section.

<plugin>
    <groupId>com.microsoft.azure</groupId>
    <artifactId>azure-webapp-maven-plugin</artifactId>
    <version>1.7.0</version>
    <configuration>
        <authentication>
            <serverId>azure-auth</serverId>
        </authentication>
        <resourceGroup>basic</resourceGroup>
        <appName>java-cicd-k8s</appName>
        <region>westus</region>
    </configuration>
</plugin>

Change 'resourceGroup' and 'appName' to your values.

Deploying

For deploying run the following command:

$ mvn clean package azure-webapp:deploy

You should see the below messages:
