I deployed mysqlcluster percona helm charts pxc operator, I can not change config for mysql from config map: auto-mysqlcluster-pxc-db-pxc. After I changed, It was reseted.  
I tried to create config map named “mysqlcluster-pxc-db-pxc” but not affected.

@namvan  
I’ve just checked on my deployment.  
After you create config map “mysqlcluster-pxc-db-pxc” , you need to restart pods one by one, so after the restart a pod will pickup a new config

Thank you for your help.  
I did wrong restart by run (nothing restarted):  
kubectl rollout restart statefulset…  
I delete pods and config affected.
