sbt-dind: (sbt alongwith docker in docker environment)

In one scenario, I had to create an SBT container for scala code compilation, and publishing images through SBT's docker native packager plugin. So to facilitate me in that scenario, I created a docker image from official docker image which supports docker in docker use-case. While creating a docker container I am mounting /var/run/docker.sock inside container so that the docker service will create sibling containers or images with host machine's docker service. You can read further about it here

Build Image:

Build this image using following command:

docker build --build-arg SCALA_VERSION=2.12.10 --build-arg SBT_VERSION=1.2.8 -t docker-sbt .

Build Code with Docker Container:

Mount your ./code inside docker container and run SBT build commands through sh shell.

docker run -it --rm -v $(pwd)/code:/code -v /var/run/docker.sock:/var/run/docker.sock docker-sbt sh -c 'cd /code; sbt update; sbt "project data-service-deploy" "docker:publishLocal"'

Upon successful execution, a newly published image can be seen in the output of docker images.
