Dockerfiles

This repository is used to automate building and stashing specific versions of dependencies that our applications rely on. This prevents sudden changes such as

• changes of the base image from bookworm to buster
• supply chain vulnerabilities

that create unexpected breakages in our applications.

rails-base

rails-base contains common dependencies that our applications use. You can use public.ecr.aws/degica/rails-base:<version> to build your rails application.
