Answer 1

Question 1:- Yes you need to add it to the root folder.
Question 2:- You have to use the dockerfile-maven-plugin to push/pull images and use the shell commands from Jenkins to run the same.
Add the SCM GIT, Stash, Hg as this
<scm>
<connection>scm:git:ssh://git#guthub.com/yourproject.git</connection>
<developerConnection>scm:git:ssh://git#guthub.com/yourproject.git[push=]scm:git:ssh://git#guthub.com/yourproject.git</developerConnection>
<tag>HEAD</tag>
</scm>
Add the plugin as
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>1.4.3</version>
<executions>
<execution>
<id>default</id>
<goals>
<goal>build</goal>
<goal>push</goal>
</goals>
</execution>
</executions>
<configuration>
<repository>${docker.image.prefix}/yourproject-${project.artifactId}
</repository>
<tag>${project.version}</tag>
</configuration>
In this while building your jar pass the arguments
mvn clean install -DskiptTests -Ddocker.image.prefix=<your docker repo url>
This command would automatically push the latest project version docker image to the repository.
Use the Shell commands to fetch this image and start the docker from the shell.
