Installing step should have docker user and group creation step as well

Hi @niharika1233, could you explain exactly what you mean. What command did you run? What error were you getting?

[niharika1233]

@spowelljr yes sir, let me just try to recreate the issue

[niharika1233]

Sir while running minikube, i found an error saying that i should not run docker as root, which required me to first add a group docker and then add a user to that docker group for the part of installation of minikube. We should either do two things 1> add a prerequisite to confirm user as docker and not root user 2> or the required steps for the docker

[spowelljr]

Adding a docker group and adding the user is part of the Docker install instructions: https://docs.docker.com/engine/install/linux-postinstall/#manage-docker-as-a-non-root-user

[niharika1233]

Please see above image, instead I am going to run it as root now.

Now to get rid of these errors i need to follow the steps for docker, now I believe at least we should tell people with a small link there and make docker user as prerequisite.

I'm not sure I understand what you're trying to suggest. Completely unrelated to minikube, when you install docker there are instructions to add your user to the docker group, as seen in https://docs.docker.com/engine/install/linux-postinstall/#manage-docker-as-a-non-root-user. It seems you accidentally missed that step, which is fine, and then when you try to start minikube we see that you forgot that step and output the following:

docker: Suggestion: Add your user to the 'docker' group: 'sudo usermod -aG docker $USER && newgrp docker' <https://docs.docker.com/engine/install/linux-postinstall/>

If you run the command we provided you it should resolve your issue, we don't support running minikube as root with the docker driver.

I believe at least we should tell people with a small link there and make docker user as prerequisite

That's what the suggestion is telling your to do already.

The suggestion that you are giving on command line thanks for that, i think you can also include as prerequisites steps in the installation webpage

Not sure if this PR #19925 can address the issue. @spowelljr PTAL
