1. Generate ssh key ssh-keygen -t rsa -b 4096 -C "{email}"

2. Rename keys

mv ~/.ssh/id_rsa ~/.ssh/project_x_id_rsa
mv ~/.ssh/id_rsa.pub ~/.ssh/project_x_id_rsa.pub

3. Add public key to "deploy keys"

• Add public key to "deploy keys" section in your github project https://github.com/user/project-x/settings/keys

4. Verify connection: sudo ssh -T git@github.com

5. Edit ssh config file:

• Edit ssh config file if you use multiple repos on server: sudo nano ~/.ssh/config and add these lines:

Host github.com-project-x
Hostname github.com
IdentityFile=~/.ssh/project_x_id_rsa

6. Clone the repo with custom host: git clone git@github.com-project-x:user/project-x

7. All good.
