Cleanup Logs

[vokary]

Hello,

I am currently running Deis v1.10.1 and the folder /var/lib/deis/store/logs contains about 100gb log data. Clearing one of the logfiles > app1.log will wipe the data from the file -> 0kb but when running deis logs -a app1 I get the following error.

panic: runtime error: index out of range
goroutine 1 [running]:

What is the safe way to cleanup this folder? My Problem is the our Deis cluster is running on DO and almost running out of diskspace

EDIT:
after scale web=0 and web=1 for app1 i can see some logs again, so is this the only way to get rid of big log files?

For a while, we toyed with the idea of adding a logrotate cron job or something of the sort to the logger.

Ultimately, we have decided against that and headed in a direction instead where Deis stores logs short term in-memory. If you want to keep your logs, you drain them to someplace else.

See #4280 for further details.
