k8s部署mysql,
BJ101856-1:/mnt/c$ k -n mcd-m8-infra get svc mariadb-galera
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
mariadb-galera ClusterIP 10.100.205.168 <none> 13306/TCP 5h43m
打开mariadb-galera 服务,mysql报很多Aborted connection 信息,看host都是10.244.0.0类似网段。关闭mariadb-galera服务,报警消失。 statefulset里的探针是有密码的。
请大神们帮分析一下。是什么原因。
