Do you have a detailed way to reproduce it?
I boot a ROS(v1.1.0) by docker-machine, try this issue, but cannot see these errors.

Checked the logrotate.conf, the file mode is 644.

[docker@v1 ~]$ ls -al /etc/logrotate.conf
-rw-r--r--   19 root     root           207 Jul 26 20:13 /etc/logrotate.conf

The system-cron kicks it off hourly, to trigger it, execute system-docker restart logrotate

It should be fixed in v1.1.1.
When you have a chance, can you confirm again in v1.1.1?

The root cause:
Run with os-logrotate:v1.1.0

system-docker run --rm -it --entrypoint /bin/bash rancher/os-logrotate:v1.1.0
bash-4.4# ls -al /etc/logrotate.conf
-rw-rw-r--    2 root     root            35 Jul 17 11:19 /etc/logrotate.conf

Run with os-logrotate:v1.1.1

system-docker run --rm -it --entrypoint /bin/bash rancher/os-logrotate:v1.1.1
bash-4.4# ls -al /etc/logrotate.conf
-rw-r--r--    2 root     root            35 Dec  8 03:32 /etc/logrotate.conf

The image os-logrotate:v1.1.0 has the wrong file mode.
