[[email protected] ~]# kubectl explain pods.metadata.[.........]
[[email protected] ~]# kubectl explain pods.spec.[........]开放端口+ip地址访问：此处的一旦绑定，只能指定的ip或者端口访问
[[email protected] ~]# kubectl explain pods.spec.containers.ports
containerPort : 容器开放端口
hostIP： 绑定宿主机ip
hostPort：绑定宿主机端口
name： 必须是IANA_SVC_NAME,并且是pod唯一
protocol ：协议端口 必须是UDP TCP SCTP类型，默认TCP
语法：
spec:
containers:
- image: nginx
imagePullPolicy: IfNotPresent
name: nginx-1
ports:
- protocol: TCP
conainerPort: 80
name: http
hostPort: 8888
[[email protected] ~]# cat nginx_pods.yaml

kind: Pod

绑定宿主机hostIP
ports：
- protocol: TCP
containerPort: 80
hostPort: 8888
name: http-nginx
hostIP: 192.168.1.101
外部客户端访问 内部ip地址的方式
service->Nodeport
[[email protected] ~]# kubectl create service clusterip nginx-dep --tcp=80:80
根据开放节点数量，直接访问（所有node节点都可以访问）hostPort 上述实例 只能指定节点的ip+端口可以访问
hostNetwork 只能访问指定宿主机ip+端口访问
spec:
containers:
- image: nginx
imagePullPolicy: IfNotPresent
name: nginx-1
hostNetwork: true原文地址：https://blog.51cto.com/9025736/2397839
