Ruby in Gitpod

It’s relatively easy to set up your Ruby project in Gitpod.

Ruby Versions

Gitpod comes with Ruby 2.5 and 2.6 pre-installed (2.6 is the default).

To change the default Ruby version, you can simply run rvm use 2.5 --default in Gitpod’s Terminal. You can also install other versions, e.g. by running rvm install 2.7.

Example Repositories

Here are a few Ruby example projects that are already automated with Gitpod:

Repository	Description	Try it
railssampleapp	Ruby on Rails tutorial sample application
Gitpod-Ruby-On-Rails	Minimal Ruby on Rails example
home-assistant.io	Open source home automation
dev.to	A platform where software developers write articles

VSCode Extensions

Here are a few useful extensions that you’ll likely want to install in your Ruby project.

Ruby Test Explorer

With the Ruby test explorer, you can run unit tests from within the Gitpod UI. To add this extension to your repository, simply add these lines to your .gitpod.yml configuration file:

vscode:
  extensions:
    - connorshea.vscode-ruby-test-adapter@0.6.1:HO9rpcRv7bmRIuo7Mty/zg==
    - hbenl.vscode-test-explorer@2.15.0:koqDUMWDPJzELp/hdS/lWw==
