How to fix docker: Got permission denied issue on Ubuntu

With .NET Core cross platform and working on Linux as well as Windows and Macs, I've started to dabble again with Ubuntu and trying to see how I can use it for work with Docker and .NET Core.

After installing the latest version of Ubuntu 20.04 and getting it up and running I started to work on installing Docker.  After looking I found several ways to install the latest stable version of Docker.

If you want to run docker as non-root user then you need to add it to the docker group.

  1. Create the docker group if it does not exist
$ sudo groupadd docker
  1. Add your user to the docker group.
$ sudo usermod -aG docker $USER
  1. Run the following command or Logout and login again and run (that doesn't work you may need to reboot your machine first)
$ newgrp docker
  1. Check if docker can be run without root
$ docker run hello-world
Taken from the docker official documentation: manage-docker-as-a-non-root-user
