kOlapsis/maintenant ? reverse-engineered prompt

Build me a self hosted monitoring app that runs as a single container and automatically discovers what is on my Docker host or Kubernetes cluster.

I want to open one web dashboard and instantly see my containers, their health, restarts, CPU, memory, network, disk use, live logs, uptime checks, TLS certificate expiry, cron or heartbeat status, and whether anything looks risky or exposed. If something breaks, it should raise an alert right away and let me send it to common places like Discord, email, Slack, Telegram, webhooks, and Teams. It should also have a simple status page for incidents and subscribers.

Please make it feel ready to drop into a homelab or small production setup, with no complicated agent setup or lots of manual config. If you need to look up current docs for Docker or Kubernetes integration, do that. Focus on a clean, easy to use interface and sensible defaults so I can just start it and have it monitor my stack immediately.
