This is the docker engine we use at Codacy to have cloc support.
You can create the docker by doing:
sbt stage
docker build -t codacy-metrics-cloc .
The docker is ran with the following command:
docker run -it -v $srcDir:/src <DOCKER_NAME>:<DOCKER_VERSION>
docker run -it -v $PWD/src/test/resources:/src codacy/codacy-metrics-cloc:latest
