Permission Denied Error When First Running Docker On Ubuntu 20.04

18th August 2020 - 4 minutes read time

Whilst setting up docker on my local development machine the other day I encountered a permission problem. After installing docker I found that I had this permission problem that meant I couldn't run docker using my local user accounts. I was therefore forced to run docker as sudo, which I didn't want to do every time.

This is the error I was getting.

$ docker run hello-world
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: 
Post http://%2Fvar%2Frun%2Fdocker.sock/v1.40/containers/create: dial unix /var/run/docker.sock: connect: 
permission denied.
See 'docker run --help'.

It turns out that docker have a section on their website dedicated to sorting out this issue. The steps involved in correcting this problemĀ are as follows.
