Received SHUTDOWN from user root. Shutting down mysqld

My MySQL error log received this command, but I did not issue it. The result is that even though I am mounted on a data volume in my host directory, the database I previously established is missing, but the error log does not have any other information
[MY-013172] [Server] Received SHUTDOWN from user root. Shutting down mysqld (Version: 8.0.32).

I removed your double post regarding the same topic.

If you want us to be able to help you, will need to see the compose file used to create the container, or the docker run command that was used to create the container. Furthermore, please attach a log output that allows to understand more about the situation.
