在 minikube 中暴露端口 [英] Expose port in minikube

问题描述

在 minikube 中，如何使用 nodeport 公开服务?

In minikube, how to expose a service using nodeport ?

例如，我使用以下命令启动一个 kubernetes 集群，并创建和公开这样的端口:

For example, I start a kubernetes cluster using the following command and create and expose a port like this:

$ minikube start
$ kubectl run hello-minikube --image=gcr.io/google_containers/echoserver:1.4 --port=8080
$ kubectl expose deployment hello-minikube --type=NodePort
$ curl $(minikube service hello-minikube --url)
CLIENT VALUES:
client_address=192.168.99.1
command=GET
real path=/ ....

现在如何从主机访问暴露的服务?我想 minikube 节点也需要配置为公开这个端口.

Now how to access the exposed service from the host? I guess the minikube node needs to be configured to expose this port as well.

推荐答案

我不太确定您要问什么，因为您似乎已经了解 minikube 服务 --url 命令，它将为您提供一个可以访问该服务的网址.为了打开暴露的服务，可以使用minikube service 命令:

I am not exactly sure what you are asking as it seems you already know about the minikube service <SERVICE_NAME> --url command which will give you a url where you can access the service. In order to open the exposed service, the minikube service <SERVICE_NAME> command can be used:

$ kubectl run hello-minikube --image=gcr.io/google_containers/echoserver:1.4 --port=8080
deployment "hello-minikube" created
$ kubectl expose deployment hello-minikube --type=NodePort
service "hello-minikube" exposed
$ kubectl get svc
NAME             CLUSTER-IP   EXTERNAL-IP   PORT(S)    AGE
hello-minikube   10.0.0.102   <nodes>       8080/TCP   7s
kubernetes       10.0.0.1     <none>        443/TCP    13m

$ minikube service hello-minikube
Opening kubernetes service default/hello-minikube in default browser...

此命令将在您的默认浏览器中打开指定的服务.

This command will open the specified service in your default browser.

还有一个 --url 选项，用于打印在浏览器中打开的服务的 url:

There is also a --url option for printing the url of the service which is what gets opened in the browser:

$ minikube service hello-minikube --url
http://192.168.99.100:31167
