Procedure to setup a local Kubernetes cluster on Docker for Mac

July 14 2018

Enable Kubernetes in the Docker for Mac Preferences:

Verify the installation:

→ kubectl cluster-info
Kubernetes master is running at https://localhost:6443
KubeDNS is running at https://localhost:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

Install Kubernetes Dashboard:

→ kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

Setup the admin user:

    # admin-user.yml
    apiVersion: v1
    kind: ServiceAccount
    metadata:
      name: admin-user
      namespace: kube-system

→ kubectl create -f admin-user.yml

Create admin-user cluster role:

    # cluster-admin-role.yml
    apiVersion: rbac.authorization.k8s.io/v1beta1
    kind: ClusterRoleBinding
    metadata:
      name: admin-user
    roleRef:
      apiGroup: rbac.authorization.k8s.io
      kind: ClusterRole
      name: cluster-admin
    subjects:
    - kind: ServiceAccount
      name: admin-user
      namespace: kube-system

   → kubectl create -f cluster-admin-role.yml

Get an OAuth Bearer Token

→ kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')

output:

Name:         admin-user-token-q5rwv
Namespace:    kube-system
Labels:       <none>
Annotations:  kubernetes.io/service-account.name=admin-user
              kubernetes.io/service-account.uid=c6f56f5b-878f-11e8-9422-025000000001

Type:  kubernetes.io/service-account-token
