It seems this line is not relevant to the context.

Let me check this separately since this code is same with the node-agent server.
If there is any problem, I will modify it for both here and the node-agent server in a separate PR.

After a preliminary check, this is basically OK.
zap.New(zap.UseDevMode(true))also initializes a logger tostderrwhich is the same withlogger logrus.FieldLoggerand the default log level isInfo. Merely, logger logrus.FieldLoggeris with more info about the log level and format, but zap.New(zap.UseDevMode(true))may not comply with them. We probably seldomly need the logs from controller-runtime to be indebug` level.

The same code in the node-agent server was introduced in this PR #2561. Since it is an old one, we don't know any other special reason for not using the provided logger.

Therefore, I suggest we keep it as is until we see problems, then we come back to change all the places the same as here.
