I am running docker on ubuntu 16.04 and would like to view the logs. However, I am unable to view logs after what I am guessing is some sort of rotation or the logs grow to a certain size.
I have not made any changes to my journald.conf, so I am using defaults there. There are containers running so the docker log outputs quite a lot of data.
Examples of what I am seeing:
systemctl docker status confirms service has been active:
since Thu 2016-10-13 18:56:28 UTC
However, when I run something like:
journalctl -u docker.service --since "2016-10-13 22:00"
The only output I get is:
-- Logs begin at Fri 2016-10-14 01:18:49 UTC, end at Fri 2016-10-14 16:18:25 UTC. --
I can view the logs in that range as expected.
My question is: why can I not view older logs with journalctl, and how can I fix this issue so I can view the logs?
