Where are auto generated SSH keys stored in Windows using azure cli --generate-ssh-keys

I am trying to create linux VM with azure cli from local machine. I was able to create VM using following command but now when I want to ssh into the VM, I need to have public key on my local machine?

How can I get the required public key to connect to vm using ssh azureuser@publicIpAddress? Where are the ssh keys generated by --generate-ssh-keys and how to get it?

az vm create \
  --resource-group myResourceGroup \
  --name myVM \
  --image UbuntuLTS \
  --admin-username azureuser \
  --generate-ssh-keys

I used PowerShell 7.0 with elevated privileges to run the above command

Solved

From MSDN for --generate-ssh-keys:

Generate SSH public and private key files if missing. The keys will be stored in the ~/.ssh directory.

Which will by default create a private id_rsa and public id_rsa.pub SSH key pair in the ~/.ssh directory if they don't exist. If you already have existing SSH keys in that location, it will just use those and not overwrite them.

On Windows this is the C:\Users\username\.ssh directory.

Additionally, you could also pass in a specific SSH public key path with --ssh-key-values:

az vm create \
  --resource-group myResourceGroup \
  --name myVM \
  --image UbuntuLTS \
  --admin-username azureuser \
  --ssh-key-values /path/to/public/key

This is particularly useful if you have created SSH keys in another location with ssh-keygen.

As @Ash pointed out in the comments, you could have a look at Generate keys automatically during deployment for more information.

You can find it under

C:\Users\<<your-user-name>>\.ssh

When you create a VM for the first time you get the below message as well

SSH key files 'C:\Users\<<your-user-name>>\.ssh\id_rsa' and 'C:\Users\<<your-user-name>>\.ssh\id_rsa.pub' have been generated under ~/.ssh to allow SSH access to the VM. If using machines without permanent storage, back up your keys to a safe location.

For subsequent VM creations, the same key pair is used and you don't see the message again.

(I verfied using Windows OS, creating a linux VM with RedHat:RHEL:7-RAW:7.4.2018010506 image via Azure CLI)
