Overview

This is a selection of Docker containers preinstalled with the latest stable version of Ruby.

We use our rbenv containers as the base to keep the install simple and consistent.

Naming convention

Local containers

ruby-latest-<os>-<version> e.g. ruby-latest-debian-10

Published containers

wolfsoftwareltd/ruby-latest-<os>:<version> e.g. wolfsoftwareltd/ruby-latest-debian:10

Development

We do not include Dockerfiles with the repository as these are generated dynamically when required. We supply a helper script to do a lot of the heavy listing. The helper script is called manage-all.sh and can be from any level of the directory tree and is recursive.

If you are in the top level directory you will need to use manage.sh instead of manage-all.sh

Generate Dockerfiles

./manage-all.sh generate

Build Containers

./manage-all.sh build [clean]

Scan Containers

./manage-all.sh scan         

Publish Containers

./manage-all.sh publish

If you want to publish the containers you will need to update the utils.sh script and change the following line.

DOCKER_HUB_ORG='wolfsoftwareltd'
