compose: Unable to find GemFile

Hey all,

I’m currently configuring docker-compose on my Linux Mint machine. The problem is, I’m able to build the web aspect of my project without errors. However, when it comes to running the rails server, rails console, or really anything that involves the rails command, I’m getting the following errors:

web_1 | Could not locate Gemfile or .bundle/ directory

/myapp/Gemfile not found

Any idea what’s going on here. Posting my docker-compose.yml and related files below.

Docker Version: 1.8.2 Docker Machine Version: 0.4.0 Docker Compose Version: 1.4.2

docker-compose.yml

db:
  image: postgres:9.4.1
  ports:
    - "5432:5432"

web:
  extends:
    file: common.yml
    service: webapp
  build: .
  command: bundle exec thin -D start
  ports:
      - "3000:3000"
  links:
      - db

Common.yml

webapp:
  environment:
      RAIL_ENV: development
  volumes:
      - .:/myapp

The volume is masking the contents of the image. You need to either remove volumes: - .:/srv/app or make sure that you have the bundle contents on the host as well. The Compose guides do this by running something like docker-compose run app bundler install ...

I’m leaving this comment as a signpost for others. The error message in the OP matched one I encountered while using a volume for bundled gems between containers ( api, resque, resque-scheduler etc).

I hit the same error using Fedora25 with SELinux and Win10 using docker-toolbox. For SELinux Permissive works, bundle completes in the build phase. For win10 it was due to the project being outside the Users folder. Moving it inside Users home allowed progress.

My docker-compose.yml

app:
  build: .
  command: bundle exec rails s -p 3000 -b '0.0.0.0'
  volumes:
    - .:/srv/app
  ports:
    - "3000:3000"
    - "80:80"
  links:
    - db
  env_file:
    - '.env.app'
db:
  image: postgres
  ports:
    - "5432:5432"

docker-compose goes OK

BUT

docker-compose up throws:

I had pretty much the same error, I also posted here. For docker-machine to work on Windows, we must place project files somewhere inside C:/Users/ otherwise volumes won’t mount, leaving an empty folder.

I suppose one can add a shared folder on the docker-machine in virtualbox’s settings in case project is in a different drive, but I did not go this way. We simply moved the project to a valid place.

(Almost) same her as Colindensem, but on Win7 instead of Win10. Whole project copied to Users folder, and starting from there: problem solved. This is not an option on the long term, but for the time being i at least can run my project. (Using this as a clue, we might find a solution that will keep the app’s on the development drive)

tried that…

Could not locate Gemfile or .bundle/ directory

Still the same

My docker file is like this:


FROM ruby:2.3.0

EXPOSE  80
EXPOSE  22
ENV     RAILS_ENV   production
ENV     TERM        xterm

RUN \
        apt-get -y update \
        && apt-get install -y --force-yes software-properties-common \nginx lynx nano curl build-essential autoconf automake libass-dev libfreetype6-dev \
        && apt-get clean \
        && rm -rf /var/lib/apt/lists/*

I would recommend trying the following:

Upgrade to the latest docker-compose 1.5.0
run a docker-compose rm to clear out old volumes, then do up again.

.:/myapp should work as a volume path
