symbols/minimal-ruby repository overview

https://github.com/gh2k/docker-minimal-ruby/⁠

This image installs RVM and Ruby in a single layer, cleaning up after itself. No dev tools are left on the image.

Historical Ruby versions are maintained back to 2.1.6. There are two sets of tags, built against Alpine 3.4 and Alpine 3.5.

• The :latest tag always points at the latest stable Ruby and the latest stable Alpine 3.5.
• Major/Minor tags point at the latest stable Ruby/Alpine for that minor number... e.g. 2.2 points at Ruby 2.2.6 and Alpine 3.5.
• For a specific version of Alpine, append _ to the tag. e.g. 2.3_3.4 uses Ruby 2.3.3 and Alpine 3.4.

Images are rebuilt when newer Alpine images are released for that branch.

Installing gems that require these (e.g. Nokogiri) will require reinstallation/removal of the tools.

Image size is ~32Mb compressed.
