我正在尝试在没有云提供商的裸机上使用 kubernetes 入口资源。
我创建了一个入口资源:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: nginx
spec:
rules:
- host: foobar.com
http:
paths:
- path: /foo
backend:
serviceName: echoheaders-x
servicePort: 80
- path: /
backend:
serviceName: frontend
servicePort: 80
但是,当我查看入口时,我得到了这个 IP:
[root@kubemaster]# kubectl get ing
NAME HOSTS ADDRESS PORTS AGE
nginx foobar.com 172.17.0.1 80 12m
该 IP 地址似乎与我所有 kubelet 节点上的 docker0 IP 地址相对应。
有没有办法设置这个IP?我读过的所有教程似乎都有这个 IP 是可路由的。
这是我的 nginx 控制器 yaml:
---
apiVersion: v1
kind: ReplicationController
metadata:
name: nginx-ingress-controller
labels:
k8s-app: nginx-ingress-lb
spec:
replicas: 1
