OpenShift服务的外部IP分配

对openshift\u master\u external\u ip\u network\u CIDR有点困惑。当服务公开时，我仍然没有获得外部IP分配

显示服务：

[root@node237 origin]# oc get svc
NAME                    CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE
cakephp-mysql-example   10.100.127.43    <none>        8080/TCP   10m
mysql                   10.100.233.247   <none>        3306/TCP   10m

我的ansible hosts文件如下所示：

# Create an OSEv3 group that contains the master, nodes, etcd, and lb groups.
# The lb group lets Ansible configure HAProxy as the load balancing solution.
# Comment lb out if your load balancer is pre-configured.

有什么建议吗

您应该创建负载平衡器类型的服务。这是一个例子

apiVersion: v1
kind: Service
metadata:
  creationTimestamp: null
  labels:
    app: mysql-ephemeral
    template: mysql-ephemeral-template
  name: mysql-ext
spec:
  ports:
  - name: mysql
    nodePort: 3306
    port: 3306
    protocol: TCP
    targetPort: 3306
  selector:
    name: mysql
  sessionAffinity: None
  type: LoadBalancer

---

创建服务时，是否将LoadBalancer指定为类型？
