Thank you! this is much better than using a regular informer and having to write a rest client for your custom resource.

Great video, as usual! The dynamic informer is interessting and I need to try it out on the next k8s controller I write!

Great content Alex 💯, mind if I ask which keyboard you using? Really digging the typing sound.

Hi, for the handlers defined, does it show the updates for all the custom resources of that type? What if I am interested in watching updates for one specific custom resource (ie. one instance of a CRD, where I could have several of them )
