Multiple Container

Maven Plugin Running Multiple Container

• With fabric8/docker-maven-plugin we can run multiple images.
• Let's run mysql, but we won't run the app that talk with this database (for now).

<images>
    <image>
        <name>docker-kubernetes:${project.version}</name>
        ...
    </image>
    <image>
        <name>myDb:${project.version}</name>
        <alias>myDb</alias>
        <build>
            <from>mysql:5.7</from>
        </build>
        <run>
            <env>
                <MYSQL_ROOT_PASSWORD>password</MYSQL_ROOT_PASSWORD>
                <MYSQL_DATABASE>docker_kubernetes</MYSQL_DATABASE>
            </env>
        </run>
    </image>
</images>

• You just need to add another <image> tag inside <images> tag.
• Here I am using mysql:5.7 image.
• Remember mysql expects that you pass some environment variable.
• With <env> tag you can set the environment variable.
• If you docker:start now, you will run both containers.
