If your goal is to "learn Docker", I have around 100+ free blog posts and ad-free YouTube videos at: https://nickjanetakis.com/blog/tag/docker-tips-tricks-and-tu...

https://github.com/nickjj/docker-node-example is an up to date Node example app[0] that's ready to go for development and production and sets up GitHub Actions. Its readme links to a DockerCon talk from about a year ago that covers most of the patterns used in that project and if not some of my more recent blog posts cover the rest.

None of my posts cover feature branch deployments tho. That's a pretty different set of topics mostly unrelated to learning Docker. Implementing this also greatly depends on how you plan to deploy Docker. For example, are you using Docker Compose or Kubernetes, etc..

[0]: You can replace "node" in the GitHub URL with flask, rails, django and phoenix for other example apps in other tech stacks.
