Keypairs
Using Keypairs (SSH keys) allows you to secure SSH access to instances (VMs). You can generate a key pair on a client from which you will connect to instances via SSH. The private key will be stored on the client, and the public key will need to be uploaded and specified during instance creation. It will be injected into the instance by cloud-init and used for OpenSSH authentication.
Quickstart
Start by clicking the Wizard button in the Control Panel. Click Create Key Pair.
Name your Keypair.
Under Keypair, paste your public key in the empty field or upload a file by clicking on "or select file". The Keypair should have the following format:
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQClkRUh/9D7QmZSPvWqJc1NBqs07t77s8lAwrVzsZMgP/vFZJtXQCRJ2NTxQOoJk7q1QEPqJtidIIz/oau2QkvOWvWB/gorbI2iCDDkK1j9XBsnp+DVmu126lAcGUb/V0U/5J3PCHYE2K4gKNoiQShIQbp/7JTsNCxwLaz2oZ5/brG5X+it6triEhRG/lqh6QiVvGWiQPaJTp6mBSQQF6AAaEMXLXeQkBiVW+UrV6bSC+tV5A5aBMwNP8L90TXl/sBoqlpuDMnIXOPwPt8UFSos/AR7hMl1JueRohuG26PNwwZ2NDCH+Uk3ER4hXZmIWEup99QJA3pmFGhJADIFy/QhClick on Next. In the summary window, click on Finish to complete the process. The new Keypair can now be used when creating new instances.
Adding Keypairs to an existing instance
For security reasons, you can’t add or modify the Keypairs (SSH keys) on your instance using the control panel after you create it, but you have several options to add and modify them via the command line. If you currently have SSH access to the instance, you can upload keys:
From your local computer, using
ssh-copy-id, which is included in many Linux distribution's OpenSSH packages.From your local computer by piping the contents of the public key into the
~/.ssh/authorized_keysfile. This is a good choice if you don’t havessh-copy-id.By SSHing to your instance and adding the public key manually, which is necessary if you do not have password-based SSH access.
Regional Availability
Keypairs are available in all regions.
Limitations
Keypairs are only supported for Linux and Unix-based instances.
