Where and how to install waagent (Linux VM Agent) via CLI?

Question

I am creating a VM from disk in azure from CLI. The VM gets created successfully, but in the properties, it shows VM agent unavailable. Because of which I am unable to ssh to the VM.
I am creating VM using the following command :

az vm create --resource-group RESOURCE-GRP-NAME --location eastus --name VM-NAME --os-type linux --attach-os-disk DISK-NAME

As I am using [--attach-os-disk] option, it does not allow me to give user name and password. So I have to install this waaagent.
But where exactly this agents needs to be installed and how? I am doing this from CLI, so answer via CLI would be better.

Solution

Depending upon operating system, the commands vary a little. Below is the link for the MSFT Documentation on how to install / update the Azure VM agent on Linux.

In fact, this is not possible. You need prepare your VHD in your local Hyper-V.
