This image can be used as a base image for Dockerfiles that require both Ruby and Node. It sets up rbenv and nodenv, along with their build plugins and dependencies, but doesn't actually pre-install any version of Ruby or Node. A Dockerfile building upon this image might look like this:
FROM noonat/rbenv-nodenv
RUN rbenv install 2.2.0 && \
CONFIGURE_OPTS="--disable-install-doc" rbenv global 2.2.0 && \
gem install bundler && \
nodenv install 0.11.9 && \
nodenv global 0.11.9If you're using an older version of Ruby, you may run into an error about OpenSSL when installing:
The Ruby openssl extension was not compiled.
ERROR: Ruby install aborted due to missing extensions
Try running `apt-get install -y libssl-dev` to fetch missing dependencies.
Ruby versions < 2.4 aren't compatible with OpenSSL 1.1, so you'll need to install an older version of SSL for these older Ruby versions. You can do that in your Dockerfile with:
RUN apt-get install -y libssl1.0-dev
