Edge Computing: Adding VM Users

Edge Computing VM's are provisioned from images which are configured with a default user. No passwords are set on creation, so you will need to ensure you Generate SSH Keys and have added them to your workload during workload creation before attempting to connect to your instance.

Default Users

The default user is based on the Operating System image you have used. You can find the default user in the table below:

Operating System	Username
CentOS 7	centos
CentOS 7 - cPanel/WHM	centos
CentOS 8	centos
Debian 10 Buster	debian
Ubuntu 18.04 LTS	ubuntu
Ubuntu 19.04	ubuntu

The default users have sudo permissions enabled.

When connecting via SSH, you will need to use the username listed in the table above. For example:

ssh centos@[instance.ip]

ssh debian@[instance.ip]

ssh ubuntu@[instance.ip]

Adding Users

Once your instance has deployed, you can add users to your instance using the adduser command as you would on any standard Linux distribution.

1. For example, to add the user john:
   

   sudo adduser john

2. You can then set a password for the user:
   

   sudo passwd john

3. If desired, add the user to the sudo group:
   
   Debian:
   

   sudo usermod -a -G sudo john

   
   Redhat:
   

   sudo usermod -a -G wheel john

Since password logins are disabled, you will have to add a public SSH key for this new user. To enforce user permissions we will add the key to the new user's profile, and not the root user.

On the virtual machine:

sudo su - john

And edit the authorized keys file for the new user and append a public rsa key.

~/.ssh/authorized_keys

Or on a remote machine with root VM access:

ssh-copy-id john@vm_ip_address

Congratulations, you have now added an additional user to your VM and have the ability to modify permissions and access.
