对于openshift_master_external_ip_network_cidrs有点困惑。当服务暴露时，我仍然没有获得EXTERNAL-IP分配。
展示服务：
[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
显示路线：
[root@node237 origin]# oc get routes
NAME HOST/PORT PATH SERVICES PORT TERMINATION
cakephp-mysql-example cakephp-mysql-example-test123.router.default.svc.cluster.local cakephp-mysql-example <all>
[root@node237 origin]#
现在，该服务已暴露，因为路由在那里。但是，没有分配EXTERNAL-IP，这实际上存在于我的ansible文件中：
openshift_master_external_ip_network_cidrs=['192.168.77.0/24']
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.

任何指针？

您应该创建Load Balancer类型服务。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
