kubectl apply -f https://github.com/radondb/radondb-mysql-kubernetes/releases/latest/download/mysql_v1alpha1_mysqlcluster.yaml

Error from server (InternalError): error when creating “https://github.com/radondb/radondb-mysql-kubernetes/releases/latest/download/mysql_v1alpha1_mysqlcluster.yaml”: Internal error occurred: failed calling webhook “vmysqlcluster.kb.io”: Post “https://radondb-mysql-webhook.mem-example.svc:443/validate-mysql-radondb-com-v1alpha1-mysqlcluster?timeout=10s”: dial tcp 10.103.66.0:443: connect: no route to host

从报错信息看是连接 10.103.66.0:443 失败

1、查看svc，Endpoints地址是 10.100.0.113:9443

[root@mysql-4 ~]# k describe svc radondb-mysql-webhook -n mem-example

Name: radondb-mysql-webhook

Namespace: mem-example

Labels: app.kubernetes.io/managed-by=Helm

Annotations: meta.helm.sh/release-name: demo

               meta.helm.sh/release-namespace: mem-example

Selector: app=mysql-operator

Type: ClusterIP

IP Family Policy: SingleStack

IP Families: IPv4

IP: 10.103.66.0

IPs: 10.103.66.0

Port: <unset> 443/TCP

TargetPort: 9443/TCP

Endpoints: 10.100.0.113:9443

Session Affinity: None

Events: <none>

2、启动一个busybox pod，

解析域名没有问题。

/ # ping radondb-mysql-webhook.mem-example.svc

PING radondb-mysql-webhook.mem-example.svc (10.103.66.0): 56 data bytes

再ping endpoint地址，也没有问题。

/ # ping 10.100.0.113

PING 10.100.0.113 (10.100.0.113): 56 data bytes

64 bytes from 10.100.0.113: seq=0 ttl=64 time=0.950 ms

64 bytes from 10.100.0.113: seq=1 ttl=64 time=0.243 ms

64 bytes from 10.100.0.113: seq=2 ttl=64 time=0.110 ms

--- 10.100.0.113 ping statistics —

3 packets transmitted, 3 packets received, 0% packet loss

round-trip min/avg/max = 0.110/0.434/0.950 ms

3、telnet endpoint port 不通

/ # telnet 10.100.0.113 9443

4、查看POD运行状态，也是running起来的状态

[root@mysql-4 ~]# k get pod -n mem-example
