为什么 docker ps 不显示我的 minikube 的 docker 容器？

Question

I am running minikube using the instructions at

https://kubernetes.io/docs/tutorials/hello-minikube/

I started minikube:

$ minikube start --vm-driver=hyperkit

and verified that it is successfully running.

I am running 'Docker Community Edition' version 18.06.1-ce-mac73.

$ minikube ssh

is working fine.

However when I do

$ docker ps

on my mac os host, it doesn't show any containers. However, when I do

$ docker ps 

after doing minikube ssh, I see about 20 containers.

So, where are the docker containers really running? Why does docker ps not show any containers on my mac?

Thank you.

Answer 1

You can use the following command to configure your Docker Host address:

eval $(minikube docker-env)

Then, when you run docker ps , you should see your containers. Read more here .

Answer 2

Docker containers are not running on your MAC host.

They are running on a VM where you can do minikube ssh to that VM.

The docker ps shows the containers in there inside that VM.

Answer 3

That's expected because you are using hyperkit driver to work as a hypervisor & launch lightweight virtual machines. Think of it as virtualbox launching VMs for you & complete k8s cluster is deployed into those VMs, all of them are well integrated.

Use below to get your virtual machine address or the server where these containers are actually running -

$ minikube ip

Answer 4

Since I can't add a comment:

To revert the change in your shell, use

eval $(minikube docker-env -u)
