Kubernetes edit svc vs edit service（是编辑同一个文件吗？）
Kubernetes edit svc vs edit service (is it editing the same file?)
我安装了 kubernetes，我觉得一切正常。
（请注意，这些是在下面编辑文件并更改为 NodePort 后的输出）

我正在按照教程安装 Kubernetes 仪表板。
https://k21academy.com/docker-kubernetes/kubernetes-dashboard/
此命令不会显示 Kubernetes 仪表板，它只会显示 kubernetes。
在他的示例中，它显示了 kubernetes Metrics scraper 和 kubernetes dashboard，当我这样做时它只显示 kubernetes。不知道为什么
sudo kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 44m
因此我只能使用以下命令编辑 kubernetes，但我不想编辑 kubernetes。我想改为编辑 service/kubernetes-dashboard。
有效但我认为不是正确的文件：
sudo kubectl edit service/kubernetes
无效：
sudo kubectl edit service/kubernetes-dashboard
所以改用这个命令来编辑 Kubernetes-dashboard
但我不确定它们是否是相同的文件：
sudo kubectl -n kubernetes-dashboard edit svc kubernetes-dashboard
第 1 题
为什么当我使用这个命令时没有显示 kubernetes 仪表板和指标抓取器？我该如何让它显示出来？
sudo kubectl get svc
第 2 题
这两个命令是在编辑同一个文件吗？
sudo kubectl edit service/kubernetes-dashboard
和
sudo kubectl -n kubernetes-dashboard edit svc kubernetes-dashboard
第 3 题
如果我编辑的文件是：
sudo kubectl -n kubernetes-dashboard 编辑 svc kubernetes-dashboard
与我使用此命令时正在编辑的文件不同：
sudo kubectl edit service/kubernetes-dashboard
如果我不确定它以前的样子，我该如何修复或恢复我用第一个命令所做的更改？
我可以以某种方式删除文件并在应用推荐后重新生成它吗？
我正在尝试安装仪表板，但没有获得外部 IP。
当您安装 dashboard 时，您使用了以下命令。
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml $ kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml
如果你打开 recommended.yaml 你会发现它使用 namespace 作为
kubernetes-dashboard。例如：
kind: Service
apiVersion: v1
metadata:
labels:
k8s-app: kubernetes-dashboard
name: kubernetes-dashboard
第 2 个答案： 不，您正在混合命名空间，因为您使用的命令很少 default 命名空间。但是，对于其他人，您使用了 kubernetes-dashboard 命名空间。
这两个命令是在编辑同一个文件吗？
sudo kubectl edit service/kubernetes-dashboard
和
sudo kubectl -n kubernetes-dashboard edit svc kubernetes-dashboard
答案 3：与答案 #2 相同。您需要使用一致的命名空间。
要还原：
您需要删除您在默认命名空间上创建的资源，并与命名空间保持一致。另外，要重新开始，您可以使用 kubectl delete -f <same path as used for installation> 清理这些东西。
kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml
kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml
例如：
kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml
