How to Import SSH Public Key to OpenStack Horizon
If you already have an SSH key pair on your computer, you can import your public key to the Horizon dashboard. Then, you will be able to use that imported key when launching a new instance.
By importing it directly to Horizon, you will eliminate the need to use tools like ssh-copy-id or manually edit the authorized_keys file. Also, your key will be available in OpenStack CLI.
Warning
After uploading your public key, you will not be able to apply it to an already created virtual machine. If you need to add a key to an existing VM, please follow this article instead: How to add SSH key from Horizon web console.
Note
You can have multiple SSH keys uploaded to your Horizon dashboard. You can then use them for different tasks.
