Access logs from the host where the container is running

[tonitonae]

Hi.

I was trying to setup fail2ban to block unsuccessful login attempts to my Wallabag instance running in Docker. However, I do not seem to find where logs are being stored and how to access them from outside the instance (is this even possible?).

Any clues on this?

Thanks

Found log in /var/www/wallabag/var/logs/prod.log which contains Authentication failure record. But if using reverse proxy will get wrong IP. (And I found /var/log/nginx/access.log is empty)
