Add an SSH key to balenaCloud.

Add an SSH key to the balenaCloud account of the logged in user.

If \`path\` is omitted, the command will attempt to read the SSH key from stdin.

About SSH keys
|
|
An "SSH key" actually consists of a public/private key pair. A typical name
|
|
for the private key file is "id_rsa", and a typical name for the public key
|
|
file is "id_rsa.pub". Both key files are saved to your computer (with the
|
|
private key optionally protected by a password), but only the public key is
|
|
saved to your balena account. This means that if you change computers or
|
|
otherwise lose the private key, you cannot recover the private key through
|
|
your balena account. You can however add new keys, and delete the old ones.
|
|
|
|
To generate a new SSH key pair, a nice guide can be found in GitHub's docs:
|
|
https://help.github.com/en/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent
|
|
Skip the step about adding the key to a GitHub account, and instead add it to
|
|
your balena account.
