How to force kolla-ansible to rotate logs with given interval [kolla-ansible]

18 Oct 2021


      Hi,
different services in kolla-ansible have different log rotation policies and I’d like to make the logs easier to maintain and search (tried central logging with Kibana, but somehow I don’t like this solution). So I tried to write common config file for all logs.
As I understand all logs should be rotated by cron container, inside of which there’s logrotate.conf file (and as I can see the logs are rotated according to this file). So I’ve copied this file, modified according to my needs and put it ina /etc/kolla/config with the name cron-logrotate-global.conf (as documentation says). And… nothing. I’ve checked permissions of this file  - everything seems to be ok, so what’s the problem? Below is my logrotate.conf file

Best regards,
Adam Tomas
