Kubernetes（k8s）中dashboard的汉化

Posted 2021-06-30 Biexiansheng

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：

 1 [root@master dashboard]# cat dashboard-deploy.yaml 
 2 apiVersion: extensions/v1beta1
 3 kind: Deployment
 4 metadata:
 5 # Keep the name in sync with image version and
 6 # gce/coreos/kube-manifests/addons/dashboard counterparts
 7   name: kubernetes-dashboard-latest
 8   namespace: kube-system
 9 spec:
10   replicas: 1
11   template:
12     metadata:
13       labels:
14         k8s-app: kubernetes-dashboard
15         version: latest
16         kubernetes.io/cluster-service: "true"
17     spec:
18       containers:
19       - name: kubernetes-dashboard
20         image: 192.168.110.133:5000/kubernetes-dashboard-amd64:v1.6.3
21         resources:
22           # keep request = limit to keep this container in guaranteed class
23           limits:
24             cpu: 100m
25             memory: 50Mi
26           requests:
27             cpu: 100m
28             memory: 50Mi
29         ports:
30         - containerPort: 9090
31         env:
32         - name: ACCEPT_LANGUAGE
33           value: zh 
34         args:
35          -  --apiserver-host=http://192.168.110.133:8080
36         livenessProbe:
37           httpGet:
38             path: /
39             port: 9090
40           initialDelaySeconds: 30
41           timeoutSeconds: 30
42 [root@master dashboard]# 

查看Service的配置，如下所示：

 1 [root@master dashboard]# cat dashboard-svc.yaml 
 2 apiVersion: v1
 3 kind: Service
 4 metadata:
 5   name: kubernetes-dashboard
 6   namespace: kube-system
 7   labels:
 8     k8s-app: kubernetes-dashboard
 9     kubernetes.io/cluster-service: "true"
10 spec:
11   selector:
12     k8s-app: kubernetes-dashboard
13   ports:
14   - port: 80
15     targetPort: 9090
16 [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。
