Kubernetes（k8s）中dashboard的汉化

1、访问服务器的http://192.168.110.133:8080/ui地址，如下所示：

使用dashboard版本registry.cn-hangzhou.aliyuncs.com/google-containers/kubernetes-dashboard-amd64:v1.5.0。

可以使用命令拉取镜像：docker pull registry.cn-hangzhou.aliyuncs.com/google-containers/kubernetes-dashboard-amd64:v1.5.0

但是貌似此版本无法进行汉化，网上也没有找到好的案例，就升级dashboard版本，发现直接就是汉化过的了，如下所示：

使用docker拉取镜像，docker pull registry.cn-hangzhou.aliyuncs.com/google-containers/kubernetes-dashboard-amd64:v1.6.3

 

2、查看dashboard的deployment的配置，如下所示：

[root@master dashboard]# cat dashboard-deploy.yaml 
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: 192.168.110.133:5000/kubernetes-dashboard-amd64:v1.6.3
        resources:
          # keep request = limit to keep this container in guaranteed class
          limits:
            cpu: 100m
            memory: 50Mi
          requests:
            cpu: 100m
            memory: 50Mi
        ports:
        - containerPort: 9090
        env:
        - name: ACCEPT_LANGUAGE
          value: zh 
        args:
         -  --apiserver-host=http://192.168.110.133:8080
        livenessProbe:
          httpGet:
            path: /
            port: 9090
          initialDelaySeconds: 30
          timeoutSeconds: 30
[root@master dashboard]# 

查看Service的配置，如下所示：

[root@master dashboard]# cat dashboard-svc.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
[root@master dashboard]# 

k8s的deploy可以管理rs，rs可以管理pod，但是此时的pod无法被外界访问，需要Service使用选择器，选择Pod的标签进行关联。

外界通过Node访问Service，Service通过选择器，选择指定的标签，和Pod进行关联。
