DevEnvImage

An automated repository for building a skeletal Docker image to bootstrap Three Rings developers. The resulting image runs Debian and has RVM, a handful of gems including Passenger, and a retro copy of OpenSSL 1.1.1w pre-compiled in. This facilitates faster bootstrapping of dev/test environments for those that use Docker for this.

Unless you're actively working on developing Three Rings, this is useless to you.

Usage

1. Include image: ghcr.io/threeringscic/devenvimage:main in your compose.yml.
2. Set a working_dir: and entrypoint:. Your entrypoint script will probably want to run via bash -lc to ensure RVM (which expects a login shell) works.
3. Furthermore, your entrypoint should check for the .ruby-version you want and install it with rvm install if necessary.
