Hi,

We have an existing droplet and I created/generate a new ssh user. How can I add this to the existing droplet?

Thanks.

In order to add an SSH key to an existing user, all you need to do is append their public key to the file ~/.ssh/authorized_keys A quick one liner to do that is:

cat path/to/key/id_rsa.pub | ssh username@remote_host "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

On Ubuntu, you can also use the handy ssh-import-id if the user has a public key registered on GitHub or Launchpad. To automatically import the key, you can run:

ssh-import-id gh:username
