OpenShiftサービスの外部IP割り当て

Question

openshift_master_external_ip_network_cidrsについて少し混乱します。サービスが公開されても、私はまだEXTERNAL-IPが割り当てられていません。

表示サービス：

[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 

ディスプレイ経路：経路があるため

[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]# 

次に、サービスは、露出しています。しかし、実際に私のansibleファイルに存在しない割り当てられた外部IPがされて次のように

openshift_master_external_ip_network_cidrs=['192.168.77.0/24'] 

マイansible hostsファイルには見えません：

Load Balancerタイプサービスを作成する必要があります。ここに例があります。

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
