2019-05-15 02:12:31 UTC - Jin Choi: Thanks, I'll look further into your option once I deploy it on k8s. Unfortunately, for the time being, I am stuck with my Openwhisk deployed on bare metal servers.
I learned `copytruncate` option from logrotate tool and it seems charming in a sense, but I am concerned with periodical I/O peaks due to the heavy copying of the log files.
You see, lots of open source solutions provide a way to reopen its log file descriptor so that we can simply move the file to another name after sending it a signal, say USR1. No doubt for better performance!.
So the question is, does `controller` on Openwhisk provide such signal handling for such a purpose? If not, do you agree that the only option left for handling the ever-growing log files is `copytruncate` from logrotate? Or do you know a beeter option for me?

2019-05-15 11:05:24 UTC - Carlos Santana: Before Kubernetes we used logstash, container output was redirected to a file on volume on the VM and then logstash would monitor the files process the new line and forward the logs (elasticsearch)
