外部网络访问K8S的POD服务端口简单实现
[[email protected] yml]# cat hostpath.yml
apiVersion: v1
kind: Pod
metadata:
name: test-pd
spec:
containers:
- image: nginx
name: test-container
ports:
- containerPort: 80
hostPort: 8081
volumeMounts:
- mountPath: /test-pd
name: test-volume
volumes:
- name: test-volume
hostPath:
path: /75shell/yml
[[email protected] yml]# kubectl create -f hostpath.yml
pod/test-pd created
[[email protected] yml]# kubectl get pods
NAME READY STATUS RESTARTS AGE
my-nginx-8lrhs 1/1 Running 0 32m

test-pd 0/1 ContainerCreating 0 5s
[[email protected] yml]# kubectl get pods

[[email protected] yml]# kubectl get po -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
my-nginx-8lrhs 1/1 Running 0 38m 172.30.94.2 v75 <none> <none>
redis-slave-w5qzn 0/1 Terminating 0 7d23h <none> v77 <none> <none>
test-pd 1/1 Running 0 6m17s 172.30.91.2 v76 <none> <none>
此时通过访问POD所在NODE的IP和映射的端口就能访问POD的服务了
