I don't know, at that point I think I'd rather use an actual log aggregation system like Loki or Kibana. That way I can search, including on pods that are now gone.

The niche between "easy to get but single-container and no search" on one side and "install with helm but search all containers including historical with full-text and metrics" on the other... seems like a tiny niche to me.

edit: oh you need to install Kubetail cluster-wide too. At least no DaemonSet I guess.
