kubectl persistent logger

A side project to re-implement kubectl logs with an interface that is friendlier for development usage. Specifically, this implementation automatically updates to follow logs for new pods added to deployments, and does not terminate upon pod termination, even if the replica count falls to zero.

Usage

To follow logs for all pods that are targeted by a specific deployment's selector:

go install git.netflux.io/rob/kubectl-persistent-logger
kubectl-persistent-logger -deployment mydeploymentname

TODO

  • Implement for other relevant resource types (replica set, stateful set)
  • Pass other options back to logger backend (--container, etc)
  • Test coverage
  • Improve context handling
  • Remove/hide debug logging
