I tried running these commands:
gem uninstall rake
rm Gemfile.lock
bundle install
gem install rake --version=12.3.3
I also tried adding rake 12.3.3 to the gemfile and running bundle install:
gem 'rake', '12.3.3'
This is my Dockerfile:
FROM ruby
RUN apt-get update -qq && apt-get install -y build-essential
# for postgres
RUN apt-get install -y libpq-dev
# for nokogiri
RUN apt-get install -y libxml2-dev libxslt1-dev
# for a JS runtime
RUN apt-get install -y nodejs
ENV APP_HOME /readpaths
WORKDIR $APP_HOME
ADD Gemfile* $APP_HOME/
RUN bundle install
ADD . $APP_HOME
I've just noticed something curios: No matter how often I run gem uninstall rake (I tried five times) I always get a message saying:
Successfully uninstalled rake-12.3.1
When I run gem install rake I get:
Successfully installed rake-12.3.3
Then, when I run gem uninstall rake again, I get again:
Successfully uninstalled rake-12.3.1
If you come to this error because of Heroku/Jekyll, this is how I fixed it:
Make sure you only have this buildpack: https://github.com/heroku/heroku-buildpack-ruby
Make sure your dyno is actually on
Your Procfile should have this: web: jekyll serve --no-watch --port $PORT --host 0.0.0.0
Make sure your have PORT configured in the config vars section of your settings
Try rebuilding the docker container.

I have a very old project I'm giving support. I'm using docker to make my builds and everything was working until this last one try.
This is my Dockerfile:
FROM ruby:2.1

CMD ["rails", "server", "-b", "0.0.0.0"]
When I try to run:
docker build . -t my_image
I'm getting:
Step 11 : RUN gem install bundler && bundle install
---> Running in 7f8e7442b423 ERROR: Error installing bundler:
bundler requires Ruby version >= 2.3.0.
I don't know how to fix this.
This is a result of a release of a new Bundler version 2.0.0 that happened on January 03, 2019. According to GitHub issue this is a desired behaviour.
As this is an old and not maintained anymore project the best option for you would be using older bundler.
You can modify the line from your Dockerfile:
RUN gem install bundler && bundle install
to the following:
RUN gem install bundler -v '$OLD_BUNDLER_VERSION' && bundle install
where $OLD_BUNDLER_VERSION should be set to last known working version, i.e. 1.16.1
Try a newer version of ruby image as your base. You are using 2.1 ( FROM ruby:2.1 ) but you need ruby version 2.3.0
My way is to use the correct bundler version and run it like this:
ENV BUNDLER_VERSION 2.2.26
RUN gem update --system \
&& gem install bundler -v $BUNDLER_VERSION \
&& bundle install -j 4
I use Docker for Windows which I use to run a Image for a Rails(v5) App.
When I do docker-compose build I get this error. I don't known where to look to debug and/or resolve this.
Here is my Dockerfile:

Need to have git installed since the base ubuntu image provides only a minimal set of installed packages (this is done to keep image size small).

This version should work. I just added git to the first apt-get install step.
I use ImageMagick on the Google Cloud Platform. I use rails and Google's App Engine Flexible Environment. So the problem is I want to upload an Image to process in more sizes. I use paperclip.
The error is:
Could not run the identify command. Please install ImageMagick.
So my question is how I can solve this issue? Uploading a Image without processing works 100%. But the issue is the processing I think. So paperclip needs ImageMagick to process the images.
The problem is I use App Engine Flexible Environment so I am not sure how to install it. I already tried it with apt-get install imageMagick
Okay really simple you need just a Dockerfile.
# This Dockerfile for a Ruby application was generated by gcloud.
# The base Dockerfile installs:
# * A number of packages needed by the Ruby runtime and by gems
# commonly used in Ruby web apps (such as libsqlite3)
# * A recent version of NodeJS
# * A recent version of the standard Ruby runtime to use by default
# * The bundler and foreman gems
FROM gcr.io/google_appengine/ruby
# Install ruby 2.3.0 if not already preinstalled by the base image
RUN cd /rbenv/plugins/ruby-build && \
git pull && \
rbenv install -s 2.3.0 && \
rbenv global 2.3.0 && \
gem install -q --no-rdoc --no-ri bundler --version 1.11.2 && \
gem install -q --no-rdoc --no-ri foreman --version 0.78.0
ENV RBENV_VERSION 2.3.0
# To install additional packages needed by your gems, uncomment
# the "RUN apt-get update" and "RUN apt-get install" lines below
# and specify your packages.
# RUN apt-get update
# RUN apt-get install imagemagick -y
RUN apt-get update && apt-get install imagemagick -y
# Install required gems.
COPY Gemfile Gemfile.lock /app/
RUN bundle install && rbenv rehash
# Start application on port 8080.
COPY . /app/
ENTRYPOINT bundle exec rackup -p 8080 -E production config.ru
After that just run gcloud preview app deploy and it will work for you.
Don't forget to change in your app.yaml runtime: ruby to runtime: custom
That's it happy coding 🎉
I am trying to use fig and docker to set up a local development environment for an existing rails app.
In the build process, I clearly see bundler installing the app's gems, but when I try to start the container with fig up or even reopen it with the /bin/bash command, the gems are not visible.
Here is the Dockerfile:
FROM ubuntu:14.04
# REPOS
RUN apt-get -qq update
RUN apt-get install -y software-properties-common
RUN add-apt-repository -y "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe"
RUN add-apt-repository -y ppa:chris-lea/node.js
RUN apt-get -y update
#INSTALL
RUN apt-get install -y -q build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison pkg-config libpq-dev make wget unzip git vim nano nodejs gawk libgdbm-dev libffi-dev
#RUBY
RUN mkdir -p /download
WORKDIR download
RUN wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.gz
RUN tar xvfz ruby-2.1.2.tar.gz
WORKDIR /download/ruby-2.1.2
RUN ./configure
RUN make
RUN make install
RUN gem update --system
RUN gem install bundler
RUN mkdir /rent
WORKDIR /rent
ADD Gemfile /rent/Gemfile
ADD Gemfile.lock /rent/Gemfile.lock
RUN bundle install --deployment
And here is the fig.yml file:
web:
build: .
command: bundle exec rails s -p 3000
volumes:
- .:/rent
ports:
- "3000:3000"
Running fig build clearly shows the app's gems being installed.
Running fig up fails with the message
bundler: command not found: rails
If I run fig run web /bin/bash and check the contents of
/local/lib/ruby/gems/2.1.0/gems
it only has bundler, rdoc, rake and a few others installed.
If I navigate to the app's directory and run the bundle command, it will install the app's gems and I can see that they are installed in the directory above. I can even start the app with rails server.
Why aren't the bundled gems being persisted in the image(container?).
I ran the rails tutuorial from the fig website and didn't have this problem.
Thanks
It seems that the problem was caused by using the --deployment flag with bundle install.
This flag's main effect is to deploy the gems to the vendor/bundle/ directory instead of the normal gem location. I checked and the gems were there, so I'm not sure why ruby couldn't find them.
Anyways, removing --deployment fixed the problem.
If you're using fig and mounted volumes, I found a solution which allows updates to the mounted files in development (like Gemfile.lock when you do fig run web bundle install) while still keeping container caching behavior.
See this for the full thing: https://gist.github.com/fotinakis/04077671bec4edf77c08
It's slightly convoluted, but basically you always install bundler and the gems as the non-root application user:
# Add 'web' user which will run the application.
RUN adduser web --home /home/web --shell /bin/bash --disabled-password --gecos ""
# Add directory where all application code will live and own it by the web user.
RUN mkdir /app
RUN chown -R web:web /app
# Install gems separately here to take advantage of container caching of `bundle install`.
# Also, ensure that gems are installed as the web user and not system-wide so that we can run
# `fig web bundle install` and the web user will have permissions to update the shared Gemfile.lock.
ADD Gemfile /app/
ADD Gemfile.lock /app/
RUN chown -R web:web /app
USER web
ENV HOME /home/web
ENV PATH $PATH:/home/web/.gem/ruby/2.1.0/bin
ENV GEM_HOME /home/web/.gem/ruby/2.1.0
ENV GEM_PATH $GEM_HOME
RUN gem install --user-install bundler
WORKDIR /app/
RUN bundle install
USER root
# Add the whole application source to the image and own it all by web:web.
# Note: this is overwritten in development because fig mounts a shared volume at /app.
ADD . /app/
RUN chown -R web:web /app
Running this will now work and update your local Gemfile.lock:
$ fig run web bundle install
