Mac 访问本地运行的kubernetes的pod容器由于使用本地docker desktop 安装的kubernete

前言

由于使用本地docker desktop 安装的kubernetes,所以启动pods后，无法在本地通过ip访问。

解决方案

将pods暴露位一个服务
kubectl expose pods podName -n namespaceName --type=NodePort --name diyName
kubectl get service -n namespaceName

» kubectl get po
NAME    READY   STATUS    RESTARTS   AGE
web-0   1/1     Running   0          155m
web-1   1/1     Running   0          155m

» kubectl expose pods web-0 --type=NodePort --name my-web-0
service/my-web-0 exposed

» kubectl get svc
NAME         TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
kubernetes   ClusterIP   10.96.0.1        <none>        443/TCP          28h
my-web-0     NodePort    10.105.106.72    <none>        80:32445/TCP     15s
nginx        ClusterIP   None             <none>        80/TCP           156m
nginx-svc    ClusterIP   10.100.224.240   <none>        80/TCP,443/TCP   136m

» curl 127.0.0.1:32445

查看该svc的yaml

其实就是将pod暴露成一个type为nodePort的service,这样就可以通过外部访问了
