A docker container will be launched that will update the cobalt.dev source files in the Cobalt repository specified by the environment variable COBALT_SRC or the current working directory, which should be the root of the Cobalt repository, if that environment variable is not set.
When the docsite service is run, the container will generate the site and host the updated cobalt.dev site locally on port 4000.
When the docsite-deploy service is run, the container will build and output the site content in the directory out/deploy/www at the root of the Cobalt directory, and copy the app.yaml deployable into out/deploy.
