Developing in Docker

Episode #414 by Teacher's Avatar David Kimura

Summary

I use Docker every day and it has make my development workflow much simpler. I don't have to deal with conflicts or issues with macOS since everything is containerized. Before, I would fight my host operating system with mismatched dependencies and configuration problems, but using Docker during my development workflow has simplified things. In this episode, we'll run through how I use Docker on Rails applications and some of the tricks I use to solve the nuances of this approach.
