A VirtualMachine deployed on the AWS Cloud.

CloudVirtualMachine

CloudVirtualMachine (CVM) serves to allow one to easily provision cheap, stateless working EC2 instances on the AWS cloud. Think of it as a Terminal.

How to use

Connect to Bastion host

Your instance is isolated and fronted by a Bastion. Therefore, to connect to your instance you need to jump via your Bastion. This is how to do it.

1. Send public SSH key to EC2.

EC2 Instance Connect works by uploading a one-time SSH public key to the Bastion host, which will grant you access via your SSH client of choice. After deployment, a pre-formatted CLI command with by outputted for you to paste into your console. It looks something like this:

aws ec2-instance-connect send-ssh-public-key --instance-id i-xxxxxxxxxxxx --instance-os-user ec2-user --ssh-public-key file://C:\Users\whoever\CloudVirtualMachine\temp_key.pub --availability-zone eu-west-1a

2. Connect via SSH

Once your public SSH key has been sent to EC2, you can now connect using the SSH client of your choice. Similarly, a sample command is generated for you. For example:

ssh -o "IdentitiesOnly=yes" -i C:\Users\whoever\CloudVirtualMachine\temp_key.pem [email protected]

Jump to worker Instance

From your Bastion host, you can now jump to your worker Instance.
