See original docs at https://github.com/fhivemind/concourse-dind for how to use this container image in Concourse jobs.
This fork makes entrypoint.sh executable, removes docker-squash and docker-compose, and uses a newer version of Docker.
This container image can be used to run Docker commands inside a container, which is handy for Concourse CI jobs to allow them to use Docker CLI commands.
docker build . -t concourse-dind
docker run --privileged concourse-dind docker run hello-world
