self-hosting Uptime Kuma on a single VPS: 23 monitors, three red, and why How I set up Uptime Kuma for a one-box self-hosted stack, which endpoints I point it at, how alerts reach my phone, why three monitors went red without anything being down, and the DNS app I kept off the box.
self-hosting I wanted my phone to buzz without running a mail server, so I picked ntfy Why ntfy beat Gotify, Pushover, Telegram and e-mail on my single VPS, how its users and tokens live in a .env file, and how alerts still arrive when the VPS is dead.
self-hosting A command channel nobody on the internet can reach: Tailscale in a container in front of a private ntfy Why my ChatOps commands go through a second, private ntfy with no public port, published to my tailnet only by a Tailscale container with Funnel switched off, and how the setup script gets there without me typing a hostname.
self-hosting Why I run my VPS from a chat topic on my phone instead of SSH How a question about logging expenses from my phone became a ChatOps listener on a private ntfy server: rebuilt four times in a day, then broken in four instructive ways once it met the real server.
