How to filter events from fabric8 sharedIndexInformer by labels?
问题
我使用 fabric8 kubernetes client v6.8.0，并初始化一个用于 CRD 的 sharedIndexInformer，如下所示：
SharedIndexInformer<MyResource> informer =
sharedInformerFactory.sharedIndexInformerFor(MyResource.class, 30 * 1000L);
informer.addEventHandler(myEventHandler);
我只想接收具有特定标签的资源的事件。
在客户端的早期版本中，这似乎很简单，因为标签选择是sharedIndexInformerFor的一个参数之一。
SharedIndexInformer<MyResource> informer =
sharedInformerFactory.sharedIndexInformerFor(
MyResource.class,
myLabelSelector,
30 * 1000L);
如何在 v6.8.0+ 中实现这一点？

I am on fabric8 kubernetes client v6.8.0 and initializing a sharedIndexInformer for a CRD like this:
SharedIndexInformer<MyResource> informer =
sharedInformerFactory.sharedIndexInformerFor(MyResource.class, 30 * 1000L);
informer.addEventHandler(myEventHandler);
I only want to receive events from resources with certain labels.
This seemed straightforward in earlier version of the client, with label selection being one of the arguments in sharedIndexInformerFor.
SharedIndexInformer<MyResource> informer =
sharedInformerFactory.sharedIndexInformerFor(
MyResource.class,
myLabelSelector,
30 * 1000L);
How to achieve this in v6.8.0+?

要更精细地控制信息筛选，您可以使用Resource DSL上可用的inform()方法：
SharedIndexInformer<MyResource> informer = client.resources(MyResource.class)
.inNamespace("default")
.withLabel("app", "test-operator")
.inform(myEventHandler, 30 * 1000L);
英文:
For more fine grained control over informers filtering, you can use the inform() method available on Resource DSL:
SharedIndexInformer<MyResource> informer = client.resources(MyResource.class)
.inNamespace("default")
.withLabel("app", "test-operator")
.inform(myEventHandler, 30 * 1000L);
