Managing SSH keys in LS Cloud

Managing SSH keys in LS Cloud, SSH keys allow 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 LS Cloud 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.

Prerequisites

• As instructed in Preparing templates, the cloud-init utility and OpenSSH Server are installed in a VM template or boot volume.

To add a public key

1. Generate an SSH key pair on a client by using the ssh-keygen utility:

   # ssh-keygen -t rsa
   

2. On the SSH keys screen, click Add key.
3. 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.
