How do I get logs from all pods of a Kubernetes replication controller?

Question

Running kubectl logs shows me the stderr/stdout of one Kubernetes container.

How can I get the aggregated stderr/stdout of a set of pods, preferably those

Answer 1

I've created a small bash script called kubetail that makes this possible. For example to tail all logs for pods named "app1" you can do:

kubetail app1

You can find the script here.
