Creating non-root user with docker permissiosn:

Adding a user with sudo permissions

First we need to create a user

useradd -G sudo -m placeholder-username -s /bin/bash

Breakdown of command:

• useradd is the command for creating a new user
• -G is tag for group, you are creating user to be put in the sudo group
• -m is for the username
• -s indicates the default shell, in this case it is /bin/bash

Next, you need to create a password for your user:

passwd placeholder-username

And That’s it! You’ve successfully created a non-root user!

To find the UID (User ID) and GID (Group ID) of that user, enter:

id placeholder-username

The output will display a number. Note down that number.

Adding docker permissions to the non-root user

Ensure docker group is created:

sudo groupadd docker

Change user to newly created user:

su placeholder-username

You will be prompted to enter your password. Enter it and continue:

Adding your non-root user to the docker group:

sudo usermod -aG docker $USER

To apply changes enter:

newgrp docker

Verify you can run docker commands without sudo:

docker run hello-world

If you see an output like the one shown below, then you have set everything up correctly!
