web_1 | /docker-entrypoint.sh: line 99: exec: bundle: not found app_web_1 exited with code 127

I’m trying to use docker to push my existing rails project to a docker container.

I’m using postgres database.

    You don’t need two instruction in your Dockerfile, just use docker-compose for overwrite postgres enviroments images.

    You can try this:

    # Dockerfile
    FROM ruby:2.2.3
    # Update ubuntu and deps
    RUN apt-get update -qq && apt-get install -y build-essential
    # Install postgres dep
    RUN apt-get install -y libpq-dev
    # Install nokogiri dep
    RUN apt-get install -y libxml2-dev libxslt1-dev
    # Install JS runtime
    RUN apt-get install -y nodejs
    ENV APP_HOME /app
    RUN mkdir $APP_HOME
    ADD Gemfile* $APP_HOME/
    # Install api deps
    RUN bundle install --jobs 4

    Now in your docker-compose.yml (I use v1 version) you can try that:

      image: postgres
      POSTGRES_USER: my-user-name
      POSTGRES_DB: app-database-name
      build: .
      command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -b ''"
        PORT: 3000
        DATABASE_URL: 'postgres://postgres:@postgres:5432/postgres'
        - '3000:3000'
        - db
        - .:/app
    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
