Setup

To set up the project, run:

git clone https://github.com/bkuhlmann/docker-alpine-ruby.git
cd docker-alpine-ruby
git checkout 5.13.0

Usage

All versions of this image can be found on Docker Hub. The image can be pulled as follows:

docker pull bkuhlmann/alpine-ruby:latest  # <= Pull latest version.
docker pull bkuhlmann/alpine-ruby:5.13.0   # <= Pull specific version.

You can also build on top of this image via your Dockerfile:

FROM bkuhlmann/alpine-ruby:latest  # <= Latest version.
FROM bkuhlmann/alpine-ruby:5.13.0   # <= Specific version.

Development

To contribute, run:

git clone https://github.com/bkuhlmann/docker-alpine-ruby.git
cd docker-alpine-ruby

To build, run:

bin/build

To use the console, run:

bin/console

To deploy the latest version, run:

bin/deploy

To automatically calculate the next logical version and deploy it, run:

bin/deploy p

Versions are calculated and created via the Milestoner gem. Best practice is to deploy both the latest version and next version. Example:

bin/deploy
bin/deploy p

The above will ensure new images are created with the following tags:

latest: This is the most recent stable version which may or may not be ahead of the last version released.
<major>.<minor>.<patch>: This the next logical version as calculated and created by Milestoner.

Tests

To test, run:

bin/console
ruby --version
