【问题描述】：
我按照手册安装了 kubernetes 仪表板。
第 1 步：
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml
serviceaccount "kubernetes-dashboard" created
service "kubernetes-dashboard" created
secret "kubernetes-dashboard-certs" created
secret "kubernetes-dashboard-csrf" created
secret "kubernetes-dashboard-key-holder" created
configmap "kubernetes-dashboard-settings" created
role.rbac.authorization.k8s.io "kubernetes-dashboard" created
clusterrole.rbac.authorization.k8s.io "kubernetes-dashboard" created
rolebinding.rbac.authorization.k8s.io "kubernetes-dashboard" created
clusterrolebinding.rbac.authorization.k8s.io "kubernetes-dashboard" created
deployment.apps "kubernetes-dashboard" created
service "dashboard-metrics-scraper" created
The Deployment "dashboard-metrics-scraper" is invalid: spec.template.annotations.seccomp.security.alpha.kubernetes.io/pod: Invalid value: "runtime/default": must be a valid seccomp profile
第二步：
kubectl proxy --port=6001 & disown
输出是 -
Starting to serve on 127.0.0.1:6001
现在当我访问该网站时 -
http://localhost:6001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/
它给出了以下错误 -
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {
},
"status": "Failure",
"message": "no endpoints available for service \"kubernetes-dashboard\"",
"reason": "ServiceUnavailable",
"code": 503
}
同时检查 pod 不显示 kubernetes 仪表板
kubectl get pod --namespace=kube-system
表演
NAME READY STATUS RESTARTS AGE
etcd-docker-for-desktop 1/1 Running 0 13d
kube-apiserver-docker-for-desktop 1/1 Running 0 13d
kube-controller-manager-docker-for-desktop 1/1 Running 0 13d
kube-scheduler-docker-for-desktop 1/1 Running 0 13d.
.
kubectl get pod --namespace=kubernetes-dashboard
返回-
NAME READY STATUS RESTARTS AGE
kubernetes-dashboard-659f6797cf-8v45l 0/1 CrashLoopBackOff 15 1h
如何解决问题？
更新：以下链接 http://localhost:6001/api/v1/namespaces/kubernetes-dashboard/services 给出以下输出 -

【问题讨论】：
-
dashboard pod 部署在自己的命名空间
kubernetes-dashboard$ kubectl get pod --namespace=kubernetes-dashboard的输出是什么？豆荚都起来了吗？ -
还将以下命令的输出添加到问题
$ kubectl get deployments -A | grep -i dashboard和$ kubectl get service -A | grep -i dashboard -
@DT。更新的问题。要检查部署和服务，它会抛出未知的速记标志：'A' in -A
-
很明显dashboard pod已经申请安装
kubernetes-dashboard-659f6797cf-8v45l 0/1 CrashLoopBackOff你可以查看pod日志看看是什么故障原因！！ -
@DT。
kubectl get pods显示找不到资源
