Docker run without root

When I run certain docker commands I get this in console, and it is because of lack of permissions.

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.40/containers/mydatabase/json: dial unix /var/run/docker.sock: connect: permission denied

To run docker as non rootuser we must do the following

Configure the docker group

sudo groupadd docker (1)
sudo usermod -aG docker $USER (2)
newgrp docker (3)
docker run hello-world (4)
1 Create the docker group, maybe the output says that the group is already created, it doesn’t matter.
2 Adding our user to the docker group.
3 Relogin in docker, be aware if it’s time to reboot, in case it doesn’t work.
4 Check if we can run without root the following command.
rubn ⲁƛ ▸ docker run hello-world

Hello from Docker! (1)
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
