Get started with SSH Key Management

Add your SSH key to TIR once, then choose it when you create an instance, a virtual machine, or a training cluster. All you need is a TIR project you can open and a computer with a terminal.

Add an SSH key

1. On your computer, run ssh-keygen -t ed25519 -C "<your comment>". <your comment> is a label such as your email address or machine name.
2. Print the public key with cat ~/.ssh/id_ed25519.pub and copy it.
3. In TIR, open the account menu at the top right and select SSH Keys. Open the Add Key menu and select Add new key.
4. Type a Key name, paste the public key into Public key, and select Add Key at the bottom of the form.

The key is now in your SSH Keys list, ready to choose under SSH Keys when you create an instance, a virtual machine, or a training cluster.

Connect with it

Once a resource with your key is running, connect from the same computer with the private key:

ssh -i ~/.ssh/id_ed25519 root@<ip-address>

<ip-address> is the IP address of the instance or cluster. The resource also needs a security group that opens port 22, such as the project’s Default-SSH-Security-Group.

What to do next

• Connect with an SSH key covers keys made in the browser and the user name each resource uses.
• To keep keys safe, see How SSH keys work.
• To sign API calls, see Personal Access Tokens.
