.
This article goes hand in hand with the User Creation Article.
Typically, a dedicated group is required for read and write access to your private EO-Storage. We will provide you a group ID in our welcome e-mail. After creating a VM, you will need to create the group separtely on each VM. Afterwards all users that shall have access to your private EO-Storage must be added to the group.
Create a group#
To create a group, use the groupadd
command:
groupadd -g GROUP_ID group_name
Example using group ID 5000:
groupadd -g 5000 group_name
Add a user to the group#
Often used flags are -a
(append) and -G
(group).
This tells usermod
we are appending to the group name that follows the option.
ubuntu@eodc:~$ sudo usermod -aG sudo your_user
ubuntu@eodc:~$ sudo usermod -aG group2,group3,group4 your_user
You can check the user groups with the id
command
ubuntu@eodc:~$ id your_user
