How to automatically gather a coredump right after an OpenShift PLEG issue

Solution Verified - Updated -

Issue

  • PLEG health errors occur randomly and intermittently
  • When a dockerd or a containerd coredump is gathered, the issue was already gone, so it does not contain useful information.

Environment

  • OpenShift Container Platform

    • 3.11

  • Docker

    • 1.13
