Coffee Script not found when compiling

Hi Gitlab-CE,

I have experimented problem when I try to install Gitlab-CE on a Docker Image based on Alpine Linux.

When I run the following command: sudo -u git bundle exec rake gitlab:assets:compile RAILS_ENV=production NODE_ENV=production

I get the following error:

I am also attaching my local Gemfile, the Dockerfile, docker-compose.yml and the entrypoint.sh.

I am also attaching the output from the command:

sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production SANITIZE=true
