Clear answers, no fluff.

A README lists 40-plus Docker Compose subcommands. In practice, running several stacks on one homelab host means using about eight of them daily, plus one gotcha: pull, logs, restart, and exec all scope to a single service if you name one.

Every Compose stack you copy from a README defaults to the same handful of ports. Here is how host vs container ports actually work, why multi-stack homelabs collide, and when to add a reverse proxy instead of publishing ports directly.

You ran docker-compose up -d on a box where that exact command has worked a dozen times before - or a Pi you just flashed, or a Synology you just rebooted - and the shell answers docker-compose: command not found. Docker itself is clearly installed; docker ps works fine. So what broke?

Bitdefender SecurePass, Kaspersky, and Norton all bundle a password manager into their antivirus suite — here is what each one actually includes, and skips, versus Bitwarden.

The real decision framework for outgrowing Docker Compose: numeric container and node thresholds, the K3s middle step most guides skip, and what migrating actually costs — grounded in a single-host homelab.

I migrated a real vault from Bitwarden to Proton Pass: what imported cleanly, what broke, and whether the bundle price beats paying separately.

Firefox saves and syncs your passwords for free with real encryption — but it's missing sharing, 2FA storage, and a true biometric vault unlock. Here's when that's fine, and when it isn't.

Docker Compose profiles let one compose.yml split services into groups (core, monitoring, backup, dev) that only start when requested, instead of every service always starting together.

100% and 110% Vollfinanzierung let you skip the deposit, but at a real cost: +0.70pp to +1.2pp on the rate. What that means in euros, what lenders require, and the expat-specific qualifying bar nobody's German-language guide covers.
