Connect Jetbrains IDE (Intellj) to Github Codespace

I recently wanted to connect a Jetbrains IDE (in my case RubyMine) to my Github codespace.

Here’s how I did it:

Github CLI

Make sure you can access your codespace via SSH with the Github CLI:

Export SSH config

• Make sure that “~/.ssh/config contains something that looks like this:

• Copy the host name (cs.somethingjrgwf7g69.dev-container)

Jetbrains IDE connection

• Open your preferred Jetbrains IDE (Intellij, RubyMine, PyCharm, …)
