Allow the existing users to do the configuration.
Step 1: add the group of the "sudo" and "docker" to the user.
admin@sonic:~$ sudo usermod -G sudo,docker newuser
Note:
-G: this option is for adding the secondary groups and allows add multiple groups.
The group of the "sudo" allows users could do the command with sudo.
The group of the "docker" allows users could login to the FRR to set the routing setting.
