kubernetes - 如何使用 Kubebuilder-v3/operator-sdk 发送事件

Question

Kubebuilder V3 documentation解释说它讨论了“如何将多个事件批处理到单个协调调用中”。但是，我在本文档中找不到任何有关事件管理的信息。

您能否提供有关如何使用 Kubebuilder-v3/operator-sdk 发送事件的信息/代码示例？

Answer 1

This part官方文档应该可以回答您的问题:

This business logic of the Controller is implemented in the Reconcile function. This function takes the Namespace and Name of a ContainerSet, allowing multiple Events to be batched together into a single Reconcile call. The function shown here creates or updates a Deployment using the replicas and image specified in ContainerSet.Spec. Note that it sets an OwnerReference for the Deployment to enable garbage collection on the Deployment once the ContainerSet is deleted.

1. Read the ContainerSet using the NamespacedName
2. If there is an error or it has been deleted, return
3. Create the new desired DeploymentSpec from the ContainerSetSpec
4. Read the Deployment and compare the Deployment.Spec to the ContainerSet.Spec
5. If the observed Deployment.Spec does not match the desired spec - Deployment was not found: create a new Deployment - Deployment was found and changes are needed: update the Deployment
