View logs with verbosity level set

[pohly]

How do I ensure these logs get printed, when I do want to view the logs at this verbosity level ?

That is determined by the Logger implementation that you are using. For example, klog has a -v parameter that sets the threshold.

we use the below to set the Logger

ctrl "sigs.k8s.io/controller-runtime"

opts := zap.Options{
	Development: true,
}

ctrl.SetLogger(zap.New(zap.UseFlagOptions(&opts)))

Then use that Logger.
reconciler := &controllers.GatewayConfigReconcilerLog{
Log: ctrl.Log.WithName("controllers").WithName("GatewayConfig"),
}

GatewayConfigReconcilerLog is using below,
type GatewayConfigReconcilerLog struct {
Log logr.Logger
}

Now, when I have the Development mode set to true as above in the Logger options, I would expect to see level 10 logs printed, but I dont. As per docs of this package debug is level 10.
l.Log.V(10).Info("req reconciled", "req", req.NamespacedName)

What is this zap package here?

You have to configure zap to enable log levels that are even lower (numerically) than Debug. See this code:

https://github.com/go-logr/zapr/blob/master/example/main.go#L42-L47 show a trivial example of setting the zapr level, too.
