The implementation of kubernetes resource extension mechanism

Yesterday, we introduced the key components of resource plug-in mechanism in k8s. Today, we will continue to see how each component communicates and the key design behind event handling in k8s 1.PluginManager PluginManager is a top-level component, which contains the key components in the previous article, coordinates its internal data flow, an ...

Diagram of the core implementation of kubernetes container lookup mechanism

After a container is pulled up by kubelet in k8s, the user can specify the way of sniffing to check the health of the container. TCP, Http and command are currently supported. Today, the implementation of the whole sniffing module is introduced to understand the implementation of its periodic detection, counter, delay and other design. 1. Explo ...
