Command add-ssh-key

Usage: juju add-ssh-key [options] <ssh key> ...

Summary:

Adds a public SSH key to a model.

Options:

-B, --no-browser-login (= false)

Do not use web browser for authentication

-m, --model (= "")

Model to operate in. Accepts [<controller name>:]<model name>

Details:

Juju maintains a per-model cache of public SSH keys which it copies to each unit (including units already deployed). By default this includes the key of the user who created the model (assuming it is stored in the default location ~/.ssh/). Additional keys may be added with this command, quoting the entire public key as an argument.

For ease of use it is possible to use shell substitution to pass the key to the command:

juju add-ssh-key "$(cat ~/mykey.pub)"
