In non-containerized Cinder, logrotate compresses old log files. /etc/logrotate.d/openstack-cinder from the Cinder package provides the "compress" option to enable this. In containerized Cinder, /var/log/containers/cinder/ rotates logs but does not compress old logs. This can easily result in the disk being filled if debugging is enabled. This doesn't appear to be Cinder-specific -- no other services logs in /var/log/containers/ are compressed either, despite the same option being present in /etc/logrotate.d/
Any idea if this is a known generic problem?
Not sure. Logrotate rules are service specific i think
They are. And they contain the "compress" directive. It just doesn't seem to work anymore.
Yup you're right. We have our own tripleo log rotate for containers. https://github.com/openstack/puppet-tripleo/blob/master/templates/logrotate/containers_logrotate.conf.erb Bogdan can you take a look at this?
