修改Service端口
增加80端口，改成http访问
修改前:
|
1 2 3 4 5 6 |
spec: ports: - port: 443 targetPort: 8443 selector: k8s-app: kubernetes-dashboard |
修改后：
|
1 2 3 4 5 6 7 8 9 10 |
spec: ports: - port: 443 targetPort: 8443 name: https - port: 80 targetPort: 9090 name: http selector: k8s-app: kubernetes-dashboard |
如果想用 ip+端口 的方式访问，这里需要增加配置，改成 nodeport 的形式，nodePort 改成自己主机空闲的端口，取值范围在 apiserver 的 --service-node-port-range 参数里面可以看得到
最终修改如下:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
spec: ports: - port: 443 targetPort: 8443 name: https nodePort: 32001 - port: 80 targetPort: 9090 name: http nodePort: 32002 type: NodePort selector: k8s-app: kubernetes-dashboard |
修改 deployment 内容
修改探针检测
后面要修改 dashboard 的启动参数，这里不改的话，活性检测会失败，导致 pod 会不断重启
修改前:
|
1 2 3 4 5 |
livenessProbe: httpGet: scheme: HTTPS path: / port: 8443 |
修改后:
|
1 2 3 4 5 |
livenessProbe: httpGet: scheme: HTTP path: / port: 9090 |
修改镜像拉取策略
官方 yaml 里面默认配置的是 Always
|
1 |
sed -i 's/imagePullPolicy: Always/imagePullPolicy: IfNotPresent/g' recommended.yaml |
修改容器端口
修改前:
|
1 2 3 |
ports: - containerPort: 8443 protocol: TCP |
修改后:
|
1 2 3 4 5 |
ports: - containerPort: 8443 protocol: TCP - containerPort: 9090 protocol: TCP |
关闭 token 登录
注释掉 --auto-generate-certificates 参数
修改前:
|
1 2 3 4 5 6 7 |
args: - --auto-generate-certificates - --namespace=kubernetes-dashboard # Uncomment the following line to manually specify Kubernetes API server Host # If not specified, Dashboard will attempt to auto discover the API server and connect # to it. Uncomment only if the default does not work. # - --apiserver-host=http://my-address:port |
修改后:
|
1 2 3 4 5 6 7 |
args: # - --auto-generate-certificates - --namespace=kubernetes-dashboard # Uncomment the following line to manually specify Kubernetes API server Host # If not specified, Dashboard will attempt to auto discover the API server and connect # to it.
