### hostPort或hostNetwork
|
||
#### hostNetwork
|
||
和containers平级的hostNetwork: true,表示pod使用宿主机网络，配合nodeSelector，把pod实例化在固定节点
|
||
```
|
||
apiVersion: apps/v1
|
||
kind: Deployment
|

metadata:

|

hostNetwork: true # 使用node节点网络
|
||
containers:
|
||
- image: nginx
|
||
imagePullPolicy: IfNotPresent
|
||
name: nginx
|
||
ports:
|
||
```
|
||
#### hostPort
|
||
和hostNetwork相比多了映射能力，可以把容器端口映射为node节点不同端口，hostPort,当然也需要nodeSelector来固定节点，不然每次创建，节点不同，ip也会改变
|

### nodePort
|
||
访问方式：集群内任意节点ip加nodePort所配端口号
