Custom config / cloud-init

acebmxer

So i am trying to learn how to use the Custom config / cloud-init for ubuntu.

If I add my ssh-key to my user account in Xen orchestra (XOA or XO-CE) I can select that during the vm creation and that works but the VM is stuck with the username ubuntu. I would to change that.

I am not sure if I am messing up the user creation or the ssh-key as i am not able to log in do to authentication error.

My config ---

#cloud-config
hostname: {name}
users:
  - newusername
ssh_authorized_keys:
      - ssh-rsa AAAAB3NzaC1.....XbZH6muQrfegKoTsuw== Generated By Termius

The above is not my actual key. In the key saved in user profile stops before the"==" and as stated that key works. So i assume if I correct the config to remove the "==" and after that key should work as well. So my assumption is the user name is the issue.

I would like to make the username to my desire but have the same permission as the user account ubuntu has when just inserting ssh-key.

Think I figured it out. first i was using the wrong key. A lot of going back and forth trying new keys forgot to swap back to original...

new config...

#cloud-config
hostname: {name}
users:
  - name: newusername
    gecos: New User
    sudo: ALL=(ALL) NOPASSWD:ALL
    groups: users, admin
    shell: /bin/bash
    ssh_authorized_keys:
      - ssh-ed25519 AAAAC3....18ZbA

Any suggestions should I not use something in the above config if the server was in production?
