thoom/summit repository overview

⁠Summit

This bunch of cool cats got together to form a little group called The Summit:

• Sinatra
• Docker
• MariaDB
• Git
• Alpine
• Thin

⁠Summary

Summit is a Docker container for a Sinatra-based web app running Ruby 2.3 on top of Thin. It downloads a Git repository and installs any bundled dependencies in a Gemfile.

It's built on top of Alpine linux so it's small. An equivalent Ubuntu build was over twice the size. The current version comes with MariaDB preinstalled. In a future revision, you'll be able to define a list of additional Alpine packages to install. At that point MariaDB may instead become an optional install.

⁠Usage

⁠Environment variables

Pass the following environment variables when instantiating the docker container:

⁠SSH_KEY

Base64 encoded SSH private key used to connect to your Git repository.

⁠GIT_REPO

The URL of the git repository.

⁠GIT_BRANCH

The branch to use (defaults to master if not passed).

⁠Git repository

Your repository must include a config.ru file in the root of the project. You may also include a Gemfile or Gemfile.lock to install any Ruby dependencies.
