Setup Local Kubernetes on Mac

A tutorial about how to setup a local k8s cluster on MacOS for development.

Setting local k8s environment with docker-desktop

1. Install Docker on Mac with this instruction, latest version of docker embedded native support for Kubernetes.
2. Start docker, once started, you’ll see Docker is running and Kubernetes is running.
3. Ensure Kubernetes is started with docker-for-desktop option, select from docker -> Kubernetes-> docker-for-desktop.
4. Set kubectl’s context to docker-for-desktop

   kubectl config use-context docker-for-desktop
   

   otherwise, kubectl will not be able to connect to the local cluster.

5. Install k8s dashboard,

   kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml -v=8
   

6. Check pod status

   kubectl get pod --namespace=kube-system | grep dashboard
   kubernetes-dashboard-669f9bbd46-p4f7c        1/1       Running   1          1h
   

7. Access dashboard

   kubectl proxy
   # URL
   http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login
   

8. Login with ACL

   kubectl -n kube-system get secret
   kubectl -n kube-system describe secrets kubernetes-dashboard-token-tf6n8
   

Backup

1. Delete dashboard service

   kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml
