Getting the core of the process running inside the pod

Question

I want to know how folks are getting the core dump of the processes running inside a pod.

Came across this issue , but its not been actively worked on, i presume.

I am just starting on this, so havent tried myself.

Answer 1

You can use Core Dump Collector Agent which exist as a Daemon Pod/Sidecar container and collects data from the location where the core dumps are created and upload the same data o external storage. Each application running inside the pod will write the core dumps in a said location in its file structure. This location will be Mounted Persistent Volume within the Kubernetes cluster.

I is possible mount to an empty directory as well rather than Persistent Volume. The storage device can be anything: AWS Cloud Storage, Google Storage, Local File Storage, etc.

Here you can find great tutorial for that.
