Clone private repository for Github Actions of another repository

Step 0: Terminology

For brevity let’s refer to the repository running the Github Actions as action_repo and the private repository that is a dependency as private_repo.

Step 1: Create private and public keys

1. ssh-keygen -t ed25519 -C “some@email.com” should do the trick
2. This creates 2 files — one with the name provided and one with the name provided and the extension .pub as can be seen in the image above.
