Your installation is collecting. This part reads every panel on the dashboard — and starts with the thing that makes this product different: it tells you in plain sentences why it thinks a visit was a person or a machine, states how many readings each figure could actually be taken from, and says "not known" rather than guess.
Your dashboard currently answers on 127.0.0.1 and nowhere else, which is safe but unusable. This part gives it a real domain name and a free, automatically renewed HTTPS certificate using Caddy — six lines of configuration, no certbot, no cron job, and no renewal to forget.
Your firewall says Default: deny (incoming). Your database is answering the internet anyway. This part shows the port scan that proves it on a real server, explains the iptables chain order that causes it, and fixes it with a Compose override file — not by fighting the firewall.
Getting an app deployed is the easy half. This final part covers what you actually do with a running app: read its logs, understand how it scales, know what it costs — and take it all down again.
