1. Generate SSH keys on the target machine

$ ssh-keygen

2. Export public key to the authorized_keys to allow the usage of this keypair to login

$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

3. Add public key from ~/.ssh/id_rsa.pub to your repository's deployment keys via Settings / Deploy keys / Add
4. Encrypt your private key with a strong password. Please use these options, otherwise this action may not be able to decrypt your key.

$ openssl enc -aes-256-cbc -md sha512 -salt -in .ssh/id_rsa -out deploy_id_rsa_enc -k PASSWORD -a

5. Add deploy_id_rsa_enc file to your repository. Suggested path is config/deploy_id_rsa_enc
6. Save the password used in step 4 as a secret in repository settings via Settings / Secrets / Add
7. Create YAML configuration for your workflow (example below)
