I just did the Kubernetes minikube tutorial at https://github.com/kubernetes/minikube, and I cannot stop or remove these containers, they always get recreated.

$ kubectl get deployment
No resource found.

$ minikube status
minikube: Running  
cluster: Running  
kubectl: Correctly Configured: pointing to minikube-vm at 192.168.99.100

Output of kubectl get pods --all-namespaces

UPDATE:

I completely removed all packages called 'kube*', removed docker, remove virtualbox, removed /var/lib/docker, reinstalled docker. And the containers are back! How on earth do you get rid of them?

回答1:

What containers do you want to delete and why? The containers printed in your docker ps output are Kubernetes containers. You basically would destroy minikube by deleting these containers.

In general Kubernetes manages these containers for you. Kubernetes interprets a deleted container as a failure and restarts it. To delete a container you have to delete the pod (or the ReplicaSet, ReplicationController or Deployment depending on your deployed applications).

If these containers actually appear on your host system, then you maybe installed Kubernetes accidentally on your host system (with another tutorial). In this case you have to look for a process called kubelet which creates these containers.

For example if you use systemd:

systemctl status kublet   # see if its actually running
systemctl stop kubelet    # stop it
systemctl disable kubelet # make sure it doesn't start after next reboot

回答2:

If you don't want to run kubernetes then minikube isn't needed and you can stop it and delete it.

minikube stop
minikube delete

Or, if you wan't it running, for some reason, just remove the environment variable DOCKER_HOST that eval $(minikube docker-env) set up for you. It points the docker client to the docker engine in minikube instead of your local machine.
