To start a docker container a DATABASE_URL environment variable must be provided. By default “krab” reads configuration from /etc/krab that must be mounted as a volume, the path can be changed by KRAB_DIR environment variable.

Pull the docker image:

docker pull ohkrab/krab:nightly

Example:

docker run --rm                          \  # remove container after command execution
        -e DATABASE_URL="..."            \  # provide connection string
        -v ${HOME}/project1:/etc/krab:ro \  # mount configuration volume
        ohkrab/krab:nightly --version    # run `--version` command from `qbart/krab:latest`

one-liner:

docker run --rm -e DATABASE_URL="..." -v ${HOME}/project1:/etc/krab:ro ohkrab/krab:nightly --version
