Rails Base Image Builder

This repository is the 'Stage 1' base image used in the builder stage on all of our rails applications.

• Stage 1 (rails-base-image-builder): Install packages to compile gems, and compile those gems.
• Stage 2 (rails-runtime-base-image): Install packages and configure OS for runtime environment.

Update gems

To update the gems in this core image, great care must be taken. Once the gemfile has been update, the lock file can be updated with a simple helper script. There are many ways of achieving this, but the recommended way is:

./gem-update.sh

Once both the Gemfile and Gemfile.lock files are both updated, a commit can be created to force a new update.
