Use of SSH keys allows you to secure SSH access to virtual machines. You can generate a key pair on a client from which you will connect to VMs via SSH. The private key will be stored on the client and you will be able to copy it to other nodes. The public key will need to be uploaded to Cloudpe and specified during VM creation. It will be injected into the VM by cloud-init and used for OpenSSH authentication. Keys injection is supported for both Linux and Windows virtual machines.
Limitations:
- You can specify an SSH key only if you deploy a VM from a template or boot volume (not an ISO image).
- If a key has been injected into one or more VMs, it will remain inside those VMs even if you delete it from the panel.
Adding Public Key
- Generate an SSH key pair on a client by using the ssh-keygen utility:# ssh-keygen -t rsa
- On the SSH keys screen, click Add key.
- In the Add SSH key window, specify a key name and copy the key value from the generated public key located in
/root/.ssh/id_rsa.pub. Optionally, you can add a key description.
Deleting Public Key
- On the SSH keys screen, select the SSH key you want to delete, and then click Delete.
- Click Delete in the confirmation window.
If this key has been injected into one or more virtual machines, it will remain inside those virtual machines.
