This image can be used as a base image for Dockerfiles that require both Ruby and Node. A Dockerfile building upon this image might look like this:
FROM noonat/ruby-node
COPY Gemfile /opt/src/Gemfile
COPY Gemfile.lock /opt/src/Gemfile.lock
COPY package.json /opt/src/package.json
WORKDIR /opt/src
RUN bundle install && \
npm installRuby 2.5.1 (and bundler) are installed via rbenv and ruby-build. I've also included the rbenv-gem-rehash plugin..
Node 8.11.2 is installed via nodenv and node-build. If you npm install -g,
be sure to RUN nodenv rehash to create shims for any scripts installed by NPM.
I wanted to have more control over what version of Ruby or Node are installed for different apps. Building from source seemed like an easier way to do that, instead of trying to track down apt packages for the correct versions.
If you require a different version of Ruby or Node, you may want to check out noonat/rbenv-nodenv.
