Docker

To use dockerfile-maven-plugin you must add your docker server server to .m2/setting.xml under the servers tag:

<server>
  <id>docker.io</id>
  <username><user id></username>
  <password><password></password>
</server>

, and in your pom add these properties:

<properties>
    <docker.image.prefix>oajamfibia</docker.image.prefix>
    <project.build.finalName>${project.artifactId}-${project.version}</project.build.finalName>
    <dockerfile-maven-version>1.4.10</dockerfile-maven-version>
</properties>

and the

maven-dependency-plugin

Unpack the jar to prepare for the dependencies to be added separately to the docker image.

dockerfile-maven-plugin

Build the docker image

, <useMavenSettingsForAuth> to use the server credentials in .m2/setting.xml

Also add the Dockerfile.

Docker in maven life cycle

Docker build and upload is now part of maven lifecycle

mvn deploy , does

• build the jar
• unpack the jar (to add the dependencies separately to the docker image)
• build the docker image
• upload the docker image to the docker repository server, in this case docker.io

Running in local docker container

To run the image named my-docker-id/my-image:0.0.1 in a local docker container, naming the container my-image-container and open port 8080

docker run --name my-image-container -p 8080:8080 -d my-docker-id/my-image:0.0.1
