mac kubernetes 安装

安装docker

1.下载k8s

这个没啥好讲的直接下载就行了

2.开启k8s环境

3.验证下

• 查看集群信息

  kubectl cluster-info

• 或取节点

  luwei@luweideMacBook-Pro-2 ~ % kubectl get nodes
  NAME             STATUS   ROLES                  AGE     VERSION
  docker-desktop   Ready    control-plane,master   3d12h   v1.21.5
  luwei@luweideMacBook-Pro-2 ~ %

• 输出指定的一个/多个资源的详细信息

  kubectl describe node

  K8S部署 Dashboard UI

  1.以官方yaml部署Dashboard U

  luwei@luweideMacBook-Pro-2 ~ % kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml
  namespace/kubernetes-dashboard unchanged
  serviceaccount/kubernetes-dashboard unchanged
  service/kubernetes-dashboard configured
  secret/kubernetes-dashboard-certs unchanged
  secret/kubernetes-dashboard-csrf unchanged
  secret/kubernetes-dashboard-key-holder unchanged
  configmap/kubernetes-dashboard-settings unchanged
  role.rbac.authorization.k8s.io/kubernetes-dashboard unchanged
  clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard unchanged
  rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard unchanged
  clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard unchanged
  deployment.apps/kubernetes-dashboard configured
  service/dashboard-metrics-scraper unchanged
  kind: ServiceAccount
  deployment.apps/dashboard-metrics-scraper configured
  luwei@luweideMacBook-Pro-2 ~ %

  2.查看dashboard运行状态，以deployment方式部署，运行2个pod及2个service：

  luwei@luweideMacBook-Pro-2 ~ % kubectl -n kubernetes-dashboard get pods
  NAME                                         READY   STATUS              RESTARTS   AGE
  dashboard-metrics-scraper-5594697f48-w57fx   0/1     ContainerCreating   0          18s
  dashboard-metrics-scraper-c45b7869d-m46ld    1/1     Running             0          4h8m
  kubernetes-dashboard-57c9bfc8c8-45qmv        0/1     ContainerCreating   0          18s
  kubernetes-dashboard-79b5779bf4-6qr4z        1/1     Running             0          4h8m
  luwei@luweideMacBook-Pro-2 ~ %

  指定Dashboard公网暴露的端口

  luwei@luweideMacBook-Pro-2 ~ % kubectl  patch svc kubernetes-dashboard -n kubernetes-dashboard  -p '{"spec":{"type":"NodePort","ports":[{"port":443,"targetPort":8443,"nodePort":30443}]}}'
  service/kubernetes-dashboard patched
  luwei@luweideMacBook-Pro-2 ~ %

修改yaml文件

• vim recommended.yaml

---
kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
spec:
  type: NodePort
  ports:
    - port: 443
      targetPort: 8443
      nodePort: 30443
  selector:
    k8s-app: kubernetes-dashboard
---

执行

luwei@luweideMacBook-Pro-2 ~ % kubectl  apply -f recommended.yaml
service/kubernetes-dashboard configured
luwei@luweideMacBook-Pro-2 ~ %

设置Token登陆

1.vim dashboard-adminuser.yaml

kind: ServiceAccount
apiVersion: v1
metadata:
  name: admin-user
  namespace: kubernetes-dashboard

---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kubernetes-dashboard

执行

luwei@luweideMacBook-Pro-2 ~ % kubectl apply -f dashboard-adminuser.yaml
serviceaccount/admin-user created
clusterrolebinding.rbac.authorization.k8s.io/admin-user created
luwei@luweideMacBook-Pro-2 ~ %

查看token

luwei@luweideMacBook-Pro-2 ~ % kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep admin-user | awk '{print $1}')
Name:         admin-user-token-tkmh6
Namespace:    kubernetes-dashboard
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: admin-user
              kubernetes.io/service-account.uid: 7eec3f89-cfeb-4a2a-b312-fdb722523bdb
