Fix Got permission denied while trying to connect to the Docker

I hit so many times this issue that I’m nearly sure you too! Bookmark this page because in this article we are going to fix the Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock:

I have a freshly installed docker in Ubuntu 20.04 LTS and straight after the installation I run

$ sudo snap install docker
docker 20.10.14 from Canonical✓ installed
d3@my-local-k3s:~$ docker ps
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json": dial unix /var/run/docker.sock: connect: permission denied

So to fix got permission denied you just need to run these 2 commands

$ sudo groupadd docker
$ sudo usermod -aG docker ${USER}

Reboot your machine (newgrp will not work with ubuntu 20) and login again

$ docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

Job done!
