SSH to Client and Preparing for the Lightbits Volume

SSH and Set Ubuntu Client Instances in Lightbits VCP

SSH to the Client Instance By default, Lightbits IAM enables the instances in the Lightbits VPC to use the web-based SSM terminal. In order to SSH from your end, follow the steps below.

1. Go to EC2 in your AWS console, and find your client under the Running instances.

2. Click Connect on the right.

3. Hover on SSH client, and copy the Example you get. This is the exact string that can be used for SSH.

• Make sure to SSH from the same location where your SSH-key is located.
• Before running the command, run chmod 400 ssh-key-prod1.pem.

4. Paste the string you copied to the terminal prompt, and you will be connected to the client server.

• Run sudo apt-get update -y and update the OS.

5. Install the extra kernel modules for AWS (which contains nvme-tcp support):

• sudo apt install -y linux-modules-extra-aws

6. Click Enter when prompted.

7. Reboot the system to have the changes take effect: sudo reboot.
8. The SSH session will close, so SSH back into the system, as above.

• Load the nvme-tcp module: sudo modprobe nvme-tcp.
• Install the upstream nvme-cli tools: sudo apt install -y nvme-cli.

9. Verify that the nvme-tcp module is loaded: lsmod | grep nvme_tcp.
10. Verify that the latest nvme-cli is installed: nvme -version.

Now that the Ubuntu client is set, you can easily create a volume on the Lightbits target node, and provision the volume to the client with nvme-connect.
