安装kubernetes-dashboard管理k8s集群

首先我们知道k8s功能十分强大，但是我们要学习它很多命令其实还是不够友好，所以需要一个web ui控制台来管理。

安装仅需要两个yaml文件

安装前提是已经安装好k8s

编写文件a.yaml（10.104.241.122改成自己的k8s的ip）

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
# Keep the name in sync with image version and
# gce/coreos/kube-manifests/addons/dashboard counterparts
  name: kubernetes-dashboard-latest
  namespace: kube-system
spec:
  replicas: 1
  template:
    metadata:
      labels:
        k8s-app: kubernetes-dashboard
        version: latest
        kubernetes.io/cluster-service: "true"
    spec:
      containers:
      - name: kubernetes-dashboard
        image:  index.tenxcloud.com/google_containers/kubernetes-dashboard-amd64:v1.4.1
        resources:
          # keep request = limit to keep this container in guaranteed class
          limits:
            cpu: 100m
            memory: 50Mi
          requests:
            cpu: 100m
            memory: 50Mi
        ports:
        - containerPort: 9090
        args:
         -  --apiserver-host=http://10.104.241.122:8080
        livenessProbe:
          httpGet:
            path: /
            port: 9090
          initialDelaySeconds: 30
          timeoutSeconds: 30

编写文件b.yaml

apiVersion: v1
kind: Service
metadata:
  name: kubernetes-dashboard
  namespace: kube-system
  labels:
    k8s-app: kubernetes-dashboard
    kubernetes.io/cluster-service: "true"
spec:
  selector:
    k8s-app: kubernetes-dashboard
  ports:
  - port: 80
    targetPort: 9090

创建Deployment

kubectl create -f a.yaml --validate  
kubectl create -f b.yaml --validate
