SSH Key Credentials

Store or generate SSH keys in Ankra for server access on provisioned self-managed clusters.

SSH key credentials store public keys that are deployed to servers during cluster provisioning. You can either provide your own public key or let Ankra generate a keypair for you. They’re required for self-managed clusters on providers such as Hetzner, OVH, DigitalOcean, UpCloud, Proxmox, and Morpheus.

Creating an SSH Key Credential

1. Choose an approach

   • Bring your own key: provide an existing SSH public key
   • Generate a keypair: Ankra generates a new Ed25519 keypair and returns the private key for you to save
2. Add to Ankra (UI)

   Go to Credentials → Add → SSH Key, enter a name, and either paste your public key or choose Generate.

3. Or via CLI

   # Generate a new keypair (via Hetzner credentials)
   ankra credentials hetzner ssh-key create --name my-key --generate
   
   # Generate a new keypair (via OVH credentials)
   ankra credentials ovh ssh-key create --name my-key --generate
   
   # Or provide your own public key
   ankra credentials hetzner ssh-key create --name my-key \
     --public-key "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5..."
   

When generating a keypair, the private key is only returned once. Save it immediately to a secure location.
