app_1        | Install missing gem executables with `bundle install`
ibuy7_db_backup_1 exited with code 0
ibuy7_app_1 exited with code 127

If your Dockerfile doesn't have commands to install bundler and other required files then then the image will not have them when you start the container.

If you run docker-compose run app gem install bundler then the new files are lost when that container stops.

You may want to add 'gem install bundler; bundle install; bundle exec rails s' to your docker-compose.yml CMD
