Fullstaq Ruby Docker images

Fullstaq Ruby is a custom build of standard MRI Ruby interpreter with memory allocator replaced, security patches applied, and more goodies on the way.

These images are intended to be used while Fullstaq and Hongli Lai haven't build their own.

Usage

Pull it directly from the quay.io registry:

docker pull quay.io/evl.ms/fullstaq-ruby:3.0.1-jemalloc-slim

Or use as base image in your Dockerfile:

ARG RUBY_VERSION=3.0.1-jemalloc

FROM quay.io/evl.ms/fullstaq-ruby:${RUBY_VERSION}-slim

Flavors

Ruby 3.0.1, 2.7.3, and 2.6.7 with jemalloc and malloctrim are available. Images are built on top of both Debian 9 (stretch) and 10 (buster):

docker pull quay.io/evl.ms/fullstaq-ruby:3.0-jemalloc-slim   # Same as quay.io/evl.ms/fullstaq-ruby:3.0.1-jemalloc-buster-slim
docker pull quay.io/evl.ms/fullstaq-ruby:3.0-jemalloc        # Same as quay.io/evl.ms/fullstaq-ruby:3.0.1-jemalloc-buster
docker pull quay.io/evl.ms/fullstaq-ruby:3.0-malloctrim-slim # Same as quay.io/evl.ms/fullstaq-ruby:3.0.1-malloctrim-buster-slim
docker pull quay.io/evl.ms/fullstaq-ruby:3.0-malloctrim      # Same as quay.io/evl.ms/fullstaq-ruby:3.0.1-malloctrim-buster

Details

Ruby is installed from official APT package repository. Rbenv isn't used.

Caveats

Bash login shell bash -l -c 'command' resets $PATH to default. It is not clear why it happens there, because in official Ruby image it works and this image is based on the same debian:stretch-slim base image.

That may hurt you if you're using whenever gem which wraps every command in Bash login shell by default. To remove this wrapping place following to the top of your config/schedule.rb:

# config/schedule.rb
set :job_template, nil
