If T2129 takes care of PaaS Alkane web logs rotation, we could also do the same for nginx logs in PaaS docker role with logrotate.

There is already a file /etc/logrotate.d/nginx, but it handles /var/log/nginx/*.log.

To use the same 90 days rotation, we can use:

/var/log/www/*/*.log {
    daily
    rotate 90
}
