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

Hi Adam,
We don't currently support customising this file via /etc/kolla/config/cron-logrotate-global.conf. Where did you see it documented?
It would be possible to support it by adding a with_first_found loop to the cron task in ansible/roles/common/tasks/config.yml.

Hi Mark, thank you for the answer. I’ve changed ansible/roles/common/templates/cron-logrotate-global.conf.j2 (minsize 0M) and ansible/roles/common/defaults/main.yml (changing cron_logrotate_rotation_interval to „daily” and cron_logrotate_rotation_count to „31") and logrotate.conf inside cron container now has my settings, but… logs still rotates according to default rules (every 6 weeks and only if the log is > than 30M).

how exactly?
