Full Description

Docker Alpine Ruby

A very small Docker image to bootstrap your Ruby code.

This Ruby Docker image is based on Alpine Linux, so it is quite small in terms of size. Sometimes, I want to have a quick run of a Ruby script and don't want to setup a complicated Ruby environment and packages, and I build this image. There are already official Ruby images, but its size is huge and it contains quite lots of unnecessary packages that I don't use often.

How to use?

puts "Hello Docker Ruby!"

$ docker-alpine-ruby docker run --rm -v $(pwd):/home -w /home petehouston/docker-alpine-ruby ruby code.rb
