If you are using ubuntu server 20.04+ logrotate should be installed out of the box. Crack open the configuration file:

sudo nano /etc/logrotate.conf

drop in the following configuration to rotate logs for rails:

/var/www/violet/current/log/*.log {
  daily
  missingok
  rotate 7
  compress
  delaycompress
  notifempty
  copytruncate
}

after editing the configuration, run the following for the change to take effect:

sudo /usr/sbin/logrotate -f /etc/logrotate.conf
