I will walk through the steps my team followed to set up a pretty nice Rails development environment using Docker and VS Code Dev ContainersI recently worked on rewriting a super old Rails app (Rails 2 Ruby 1.8.7).

Here, I’ll walk through the steps we followed to set up a pretty nice-to-work-with Rails development environment using Docker and VS Code Dev Containers.
