• Save .pub file content to your local client for use later
• Move .pem key to ~/.ssh/ or suitable location
• Change key file permission: sudo chmod 400 repo-name.deploy.pem

4. Create ssh-config file

• Navigate to ~/.ssh and touch config set permission sudo chmod 644 config

Host gitreponame
Hostname github.com
IdentityFile ~/.ssh/repo-name.deploy.pem

5. Add the content from the public key file i.e. .pub to your github repository, settings > deploy keys > Add deploy keys

6. Set the remote git repository url on the server for the initalized git repo

• git remote add origin git@gitreponame:organization-name/repo-name.git or if already existing git remote set-url origin git@gitreponame:organization-name/repo-name.git
• test with: git remote -v

7. Add files to commit and push them to the master branch

• git add .
• git commit -m 'root commit'
