Watching logs of several pods

One thing that always bothered me was that I couldn’t get logs of several pods at once with kubectl. A simple tail -f <path-to-logfile> isn’t possible. Certainly you can use kubectl logs -f <pod-id>, but it doesn’t help if you want to monitor more than one pod at a time.

This is something you really need a lot, at least if you run several instances of a pod behind a deployment and you don’t have setup a log viewer service like Kibana.

kubetail comes to the rescue, it is a small bash script that allows you to aggregate log files of several pods at the same time in a simple way. The script is called kubetail and is available at GitHub.
