Add missing steps to the ssh instructions: - An ssh key needs to be generated locally and added to github before adding it to authorized_keys on the hub - The local ssh config needs IdentityFile pointing to the private key on the local machine

There was a problem hiding this comment.
Thanks for fixing this gap! One suggestions:
Keep GitHub out of the loop.
Pasting the public key directly into authorized_keys keeps the hub key single-purpose, such that it can't also authenticate to GitHub for git operations, and hub access no longer depends on your GitHub key
list:
# local machine
ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519_hub -C "veda-hub"# in a JupyterLab terminal on the hub
mkdir -p ~/.ssh && chmod 700 ~/.ssh
cat >> ~/.ssh/authorized_keys # paste contents of id_ed25519_hub.pub, Ctrl-D
chmod 600 ~/.ssh/authorized_keysI haven't manually tested this suggestions, and recommend checking that it works as expected before putting them in the doc.

While I was testing, I noticed that different instructions are also needed if you create a custom named server. All commands tested on my computer (Mac). |
