Potential bug in KubernetesProvider.
We have observed pods not getting new topology from the KubernetesProvider.

This could potentially be any of the following issues:

  • Outdated Kubernetes client, the issue was seen in 0.17.0
  • Bug in KubernetesProvider, e.g. the watch for some reason hangs
  • Some form of deadlock in MemberList when processing topology changes
  • Other?

Actions.

  • More logging and added timeouts for KubernetesProvider watcher.
  • Make it possible to stream event stream data to the outside world for diagnostics.
