Take Thread-Dump or Heap-Dump of K8s Pod

How do we take thread-dump, heap-dump and Container capture in certain condition before pod die for debugging purpose for certain bugs or scenario in kubernetes ?
Might be we can utilize some event hooks while pod is getting killed.

No source files, tests, or entry points are mentioned. Start by examining the proposed Kubernetes event-hook approach for capturing thread dumps, heap dumps, and container state before pod termination; done would require a concrete, agreed implementation or documented procedure for the stated conditions.
