Before we take a look at the actual GitHub action we’re going to generate an SSH key:

Code Block

language	bash

ssh-keygen -m PEM -t rsa -b 4096 -C "you@your_mail.tld"

Our SSH key is required to be in PEM format, hence the -m PEM flag.

...

We’ll do so using ssh-copy-id:

Code Block

language	bash

ssh-copy-id -i /path/to/your/key youruser@yourhost

This will copy the public key of your key pair to the remote host and add it to its list of authorized_keys.

Or if you are already on on the server via terminal, you just append the new public key to the authorized_keys file.

Code Block

language	bash

ssh-copy-id -i /path/to/your/key youruser@yourhostcat <your_public_key_file> >> ~/.ssh/authorized_keys

Info
Note the double `>` without the double `>` the existing contents of authorized_keys will be over-written (nuked!) and that may not be desirable
