大家可能都知道k8s默认有个ui界面,但是呢,一般都使用的是1版本的,今天给大家部署的是2版本页面

完整部署文件 Github 地址:https://github.com/my-dlq/blog-example/tree/master/kubernetes/kubernetes-dashboard2.0.0-deploy

接下来开始部署

部署一共分5个步骤:
1、创建RBAC
2、创建configmap和secret
3、创建dashboard
4、创建metrics-scraper
5、创建访问的serviceaccount

我吧文件直接都配好了放到了百度网盘,你们可以直接下载解压使用

完成之后就可以通过web页面访问了

这里使用的是kubeadmin部署的,如果是二进制,需要修改api-server的参数不然无法支持metrics-server服务的

1、创建 Dashboard RBAC 部署文件
cat > k8s-dashboard-rbac.yaml apiVersion: v1
kind: ServiceAccount
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kube-system

apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kube-system
rules:

  • apiGroups: [""]
    resources: ["secrets"]
    resourceNames: ["kubernetes-dashboard-key-holder", "kubernetes-dashboard-certs", "kubernetes-dashboard-csrf"]
    verbs: ["get", "update", "delete"]
  • apiGroups: [""]
    resources: ["configmaps"]
    resourceNames: ["kubernetes-dashboard-settings"]
    verbs: ["get", "update"]
  • apiGroups: [""]
    resources: ["services"]
    resourceNames: ["heapster", "dashboard-metrics-scraper"]
    verbs: ["proxy"]
  • apiGroups: [""]
    resources: ["services/proxy"]
    resourceNames: ["heapster", "http:heapster:", "https:heapster:", "dashboard-metrics-scraper", "http:dashboard-metrics-scraper"]
    verbs: ["get"]

    apiVersion: rbac.authorization.k8s.io/v1
    kind: ClusterRole
    metadata:
    labels:
    k8s-app: kubernetes-dashboard
    name: kubernetes-dashboard
    rules:

  • apiGroups: ["metrics.k8s.io"]
    resources: ["pods", "nodes"]
    verbs: ["get", "list", "watch"]

    apiVersion: rbac.authorization.k8s.io/v1
    kind: RoleBinding
    metadata:
    labels:
    k8s-app: kubernetes-dashboard
    name: kubernetes-dashboard
    namespace: kube-system
    roleRef:
    apiGroup: rbac.authorization.k8s.io
    kind: Role
    name: kubernetes-dashboard
    subjects:

  • kind: ServiceAccount
    name: kubernetes-dashboard
    namespace: kube-system

    apiVersion: rbac.authorization.k8s.io/v1
    kind: ClusterRoleBinding
    metadata:
    name: kubernetes-dashboard
    namespace: kube-system
    roleRef:
    apiGroup: rbac.authorization.k8s.io
    kind: ClusterRole
    name: kubernetes-dashboard
    subjects:

  • kind: ServiceAccount
    name: kubernetes-dashboard
    namespace: kube-system
    EOF

部署
kubectl apply -f k8s-dashboard-rbac.yaml

2、创建 ConfigMap、Secret
cat >k8s-dashboard-configmap-secret.yamlapiVersion: v1
kind: Secret
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard-certs
namespace: kube-system
type: Opaque

apiVersion: v1
kind: Secret
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard-csrf
namespace: kube-system
type: Opaque
data:
csrf: ""

apiVersion: v1
kind: Secret
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard-key-holder
namespace: kube-system
type: Opaque

kind: ConfigMap
apiVersion: v1
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard-settings
namespace: kube-system
EOF

3、部署 Dashboard Config & Secret
kubectl apply -f k8s-dashboard-configmap-secret.yaml

创建 Dashboard Deploy 部署文件
cat >k8s-dashboard-deploy.yamlkind: Service
apiVersion: v1
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
namespace: kube-system
spec:
type: NodePort
ports:

  • port: 443
    targetPort: 8443
    nodePort: 31001
    selector:
    k8s-app: kubernetes-dashboard

    kind: Deployment
    apiVersion: apps/v1
    metadata:
    labels:
    k8s-app: kubernetes-dashboard
    name: kubernetes-dashboard
    namespace: kube-system
    spec:
    replicas: 1
    revisionHistoryLimit: 10
    selector:
    matchLabels:
    k8s-app: kubernetes-dashboard
    template:
    metadata:
    labels:
    k8s-app: kubernetes-dashboard
    spec:
    containers:

    • name: kubernetes-dashboard
      image: kubernetesui/dashboard:v2.0.0-rc3
      ports:
      • containerPort: 8443
        protocol: TCP
        args:
      • --auto-generate-certificates
      • --namespace=kube-system #设置为当前namespace
        volumeMounts:
      • name: kubernetes-dashboard-certs
        mountPath: /certs
      • mountPath: /tmp
        name: tmp-volume
        livenessProbe:
        httpGet:
        scheme: HTTPS
        path: /
        port: 8443
        initialDelaySeconds: 30
        timeoutSeconds: 30
        volumes:
    • name: kubernetes-dashboard-certs
      secret:
      secretName: kubernetes-dashboard-certs
    • name: tmp-volume
      emptyDir: {}
      serviceAccountName: kubernetes-dashboard
      tolerations:

      effect: NoSchedule
      EOF

部署 Dashboard Deploy
kubectl apply -f k8s-dashboard-deploy.yaml

4、创建 Dashboard Metrics 部署文件

      ports:
      • containerPort: 8000
        protocol: TCP
        livenessProbe:
        httpGet:
        scheme: HTTP
        path: /
        port: 8000
        initialDelaySeconds: 30
        timeoutSeconds: 30
        volumeMounts:
        • mountPath: /tmp
          name: tmp-volume
          securityContext:
          allowPrivilegeEscalation: false
          readOnlyRootFilesystem: true
          runAsUser: 1001
          runAsGroup: 2001
          serviceAccountName: kubernetes-dashboard
          nodeSelector:
          "beta.kubernetes.io/os": linux
          tolerations:
    • key: node-role.kubernetes.io/master
      effect: NoSchedule
      volumes:
    • name: tmp-volume
      emptyDir: {}

EOF
部署 Dashboard Metrics
kubectl apply -f k8s-dashboard-metrics.yaml

5、创建 Dashboard ServiceAccount 部署文件

cat > k8s-dashboard-token.yamlkind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1

rbac.authorization.kubernetes.io/autoupdate: "true"
roleRef:
kind: ClusterRole
name: cluster-admin

部署访问的 ServiceAccount

kubectl apply -f k8s-dashboard-token.yaml
获取 Token
kubectl describe secret/$(kubectl get secret -n kube-system |grep admin|awk ‘{print $1}‘) -n kube-system
