ifpironimages/ruby-build repository overview

This Dockerfile builds a lightweight linux image based on Alpine Linux (5MB to start) with all the tools needed to build a Ruby project (i.e. compile/install gems).

It includes postgres support as a library (i.e. not the Postgres server, but just library code to compile against)

It is currently customized to projects I am working on, so it may not have all the necessary libraries.

It installs Ruby 2.3.7 and Bundler 1.17.3

NOTE: This is for building. For running a Ruby project in a docker image use: ifpironimages/ruby-run
