Hi @fengyingbanbo,

Hi,
I recommend that you should see this post below some guide, for local testing K8s on a Minikube cluster.

How to deploy Tutor on Minikube (Demo/example)

Hello everyone, We just tried Tutor K8s on Minikube, and we would like to share it on this platform. May be that’s can be useful for someone Sincerely, Murat Tutor Kubernetes deployment Tutor deployment on local Minikube cluster: Kubernetes is advanced challenge, but it’s very handy tool and technology for Docker based platforms, such as Tutor. In this documentation we will be try to deploy Tutor/Open edX on local Kubernetes cluster, which is Minikube. Host machine is Linux…

Because it’s has been used several times and, it works. If you already configured your local cluster and tutor dependencies, you should try stop all running containers, and check the Docker, docker-compose permissions.

$ tutor local stop

To stop all running containers

$ docker stop $(docker ps -aq)

Running docker commands without SUDO (if it’s necessary)

$ sudo usermod -aG docker $USER

If you using Minikube, to enable Ingress, and in addition to Dashboard for GUI interface of Kubernetes.

$ minikube addons ingress
$ minikube addons dashboard
$ minikube addons list

$ tutor k8s quickstart

God luck !
