反正有没有获得kubernetes集群的外部端口 [英] Is there anyway to get the external ports of the kubernetes cluster

问题描述

我已经在kubernetes的所有节点上的外部端口上公开了一项服务 群集来自:

I have exposed a service on an external port on all nodes in a kubernetes cluster from:

kubectl create -f nginx-service.yaml

您已经在服务中所有节点上的外部端口上公开了服务 簇.如果您想将此服务提供给外部互联网，则可以 需要为服务端口(tcp:30002)设置防火墙规则以提供流量.

You have exposed your service on an external port on all nodes in your cluster. If you want to expose this service to the external internet, you may need to set up firewall rules for the service port(s) (tcp:30002) to serve traffic.

请参见 http://releases.k8s.io /release-1.2/docs/user-guide/services-firewalls.md 了解更多详细信息. 服务"nginx-service"已创建.

See http://releases.k8s.io/release-1.2/docs/user-guide/services-firewalls.md for more details. service "nginx-service" created.`

反正还有kubernetes集群的外部端口吗?

Is there anyway to get the external ports of the kubernetes cluster?

推荐答案

kubectl get svc --all-namespaces -o go-template='{{range .items}}{{range.spec.ports}}{{if .nodePort}}{{.nodePort}}{{"\n"}}{{end}}{{end}}{{end}}'

这将获取所有名称空间中的所有服务，并且基本上会执行以下操作:对于每个服务，对于每个端口，如果定义了nodePort，则打印nodePort".

This gets all services in all namespaces, and does basically: "for each service, for each port, if nodePort is defined, print nodePort".
