Watching Logs of Several Pods

One thing that always bothered me was that I couldn't get the 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 deploymentand you don't have a log viewer service like Kibana set up.

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