Rebuild command fails when passing an authorized_keys

[dkam]

Rebuilding a host fails with incorrect error message

$ linode-cli linodes rebuild 1234 --root_pass somepassword --authorized_keys ~/.ssh/id_ed25519.pub
Request failed: 400

The key used is ed25519 and is the same key in my Linode profile.

The command also fails if I pass in the key id retrieved from linode-cli sshkeys list

$ linode-cli linodes rebuild 123 --root_pass somepassword --authorized_keys 1234

Ohhh - you actually have to pass in the value of the key, but not the comment like
--authorized_keys ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAINabcde

Not:

--authorized_keys `cat ~/.ssh/id_ed25519.pub`

Maybe authorized_keys should test if the argument is a file? Alternatively, perhaps it should accept the comment in an ssh file?

I like the idea of looking for a file if the input looks like a path. What comment do you have in your public key that it isn't accepting?

[dkam]

Actually, it was a matter of quoting - this works:

--authorized_keys "`cat ~/.ssh/id_ed25519.pub`"

or

--authorized_keys "$(cat ~/.ssh/id_ed25519.pub)"
