Create directory to hold ssh keys that will be generated during following steps. Such key pairs are used for automating logins, single sign-on, and for authenticating hosts (for example cloning project from your private repo on Github straight to your aws machine). It seems ideal to keep importing their public keys from github if possible. Test the SSH connection using the following code: ssh -T git@github.com . If instead, you get the output : cat: ~/.ssh/id_rsa.pub: No such file or directory, then you will need to create an SSH Key first.
