I am running into a little problem with my Docker logs on a critical piece of infrastructure. Apparently we started the container without the --log-opt max-size
setting so the logs now grow at a pretty alarming rate. I would like to avoid having to restart the service but need to limit the amount of logfiles docker is writing to disk.
Is there a way to set the max log size without restarting the container?
We are running docker 1.10.3-0~trusty
on `Ubuntu 14.04

You can use logrotate. It is installed by default on Ubuntu servers and you can check
/etc/logrotate.d/
for existing logrotate policies.Following is an example policy to rotate log files daily. You can copy-paste this to
/etc/logrotate.d/docker-logs
