端口转发时 kubectl 连接失败

Question

尝试连接转发端口后出现以下错误

IPv4：拨打 tcp4 127.0.0.1:8000：连接：连接被拒绝 IPv6 拨打 tcp6：地址 localhost：找不到合适的地址 错误：与 Pod 失去连接

用于转发端口的命令：

kubectl port-forward --address 127.0.0.1 pods/pod-name 9000:8000 -n 命名空间

我正在尝试使用远程调试通过此端口从 Eclipse 进行连接。

我希望从 Eclipse 上连接到这个端口。

我有同样的问题，但它确实可以指向服务。

所以，这失败了：

➜ kubectl port-forward argocd-server-557c4c6dff-wgbb5 8888:80
Forwarding from 127.0.0.1:8888 -> 80
Forwarding from [::1]:8888 -> 80
Handling connection for 8888

但这有效：

➜ kubectl port-forward svc/argocd-server 8888:80
