But when i use sudo it says:

💡 If you are running minikube within a VM, consider using --driver=none:

Hi @aslambaba

I believe you need to be in the docker group in order for the docker command-line to work. Can you confirm that docker is broken if you type:

docker ps

If so, try this to join the docker group:

newgrp docker

Otherwise, please check these instructions: https://docs.docker.com/engine/install/linux-postinstall/

Please let me know what works for you, so that we can update this error message with clearer instructions. Thank you!

Minikube requires to be able to run docker without sudo, but that is not the default installation.

We noticed this with the generic driver, and there a step was added to give the user root-access.

commit https://github.com/kubernetes/minikube/pull/6873/commits/3117473837ca0b55f6ab20f442413f8285fc4627

Note that this is a security risk, when doing it on the host - as opposed to in a dedicated VM.

As in: https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface

But the error could be improved. (Also seen in #7534)

Now it looks like:

❗  'docker' driver reported an issue: "docker version --format {{.Server.Version}}" exit status 1: 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/version: dial unix /var/run/docker.sock: connect: permission denied
