Can you paste a sample Chefile that references a dockerfile? I'd like @JamesDrummond to add it into the docs and maybe we include it in the release notes. We'll introduce this as a new feature of Chefiles.

@TylerJewell the documentation was already documenting the case but the implementation was not implementing it and there was an example
https://www.eclipse.org/che/docs/chedir/chefiles/index.html

Here is a sample Chefile (the same Java/Mysql docker compose than inside stacks.json but without the extra \n)

workspace.runtime.docker.composefile=`services:
 db:
  image: mysql
  environment:
   MYSQL_ROOT_PASSWORD: password
   MYSQL_DATABASE: petclinic
   MYSQL_USER: petclinic
   MYSQL_PASSWORD: password
  mem_limit: 1073741824
 dev-machine:
  image: eclipse/ubuntu_jdk8
  mem_limit: 2147483648
  depends_on:
    - db
`

Thanks - that is sufficient. I think we are good here.
