How do I customize and initialize a database

[Heyz6]

If I need to execute init. SQL to initialize the database I need when the database is created, what should I do? In addition, why does the database refuse me to use root -h to log in to the sample-leader

1. Customized init.sql (wip)
2. Access to root user remotely is not safe. At present, root@% is for Operator only. If you need to use super users remotely, you can create an additional super user

Hello developers @runkecheng 1、https://github.com/radondb/radondb-mysql-kubernetes/releases/download/v2.2.0/mysql_v1alpha1_mysqlcluster_mysql8.yaml Whether this file supports database initialization? 2、Customized init.sql (wip) Could you give me some guidance? 3、persistence If I don't use PVC, I just want to use the local HostPath support

For 1,2: We are developing this feature, It is expected to be supported in the next version For hostpath: It is not conflicting to use both hostpath and PVC. You can use the local-hostpath storageclass of OpenEBS(refer https://openebs.io/docs/user-guides/localpv-hostpath)

Regarding the first and second points, I am looking forward to your support as soon as possible, which will be more flexible. For the third point, I will take your advice. Thank you very much. @runkecheng
