Testing the image

Create a fresh repository or fork the existing registry repository.
Create a new ssh-key:

ssh-keygen -t ed25519
```
Copy the public key into the deploy keys on GitHub: https://github.com/XXX/YYY/settings/keys. Don't forget to add write-access.
Create a known_hosts file:
```
ssh-keyscan github.com > known_hosts
```
Start docker if not already running sudo systemctl start docker
