I notice mysql has multiple connections from rancher UI, is this normal? Also there a way to clear logs from mysql properly.
The UI is 100% client-side and interacts only with the API; it has no access to the database. So what do you mean by “connections”, and/or “MySQL”?
If you mean the
rancher/server container, and the built-in default database server (or an external one you configured), then yes, the server does connection pooling and maintains a bunch of open connections.
