Automation

Two halves apt patches Debian. My homelab is not Debian — it’s about a dozen containers sitting on top of Debian. AdGuard, Authentik, Vaultwarden, Caddy, n8n, Greenbone, Homepage. apt will never once mention that Vaultwarden cut a release. So “keep the lab patched” is really two jobs: Debian packages — unattended-upgrades, already a solved problem, just needs scheduling and a report. Everything I actually run — nobody’s solved that for me. Containers only update when I decide to pull. This post is both halves. The first one taught me something uncomfortable about monitoring, so I’ll start there. ...

The problem I set out to solve My homelab takes a backup every night at 20:30. A cron job runs a script, the script dumps my Authentik database, snapshots the Vaultwarden vault, tars up the configs, encrypts a copy with age and drops it into OneDrive. It writes everything it does to /var/log/lab-backup.log. And nobody reads /var/log/lab-backup.log. That was the thing bothering me. If the backup silently stopped, I wouldn’t find out when it stopped — I’d find out the day I needed a restore, which is the worst possible day to learn anything. So the plan was simple: get n8n to check the backup actually happened, and buzz my phone if it didn’t. ...

The blog you’re reading was published by the pipeline this post describes. Why Hugo, and why self-hosted I needed somewhere to document real technical work — networking, security, mod projects — that I could point to from LinkedIn. Hosted platforms were out: no content ownership, paywall friction, someone else’s branding. Hugo won on attack surface. It’s a single Go binary — no Node, no node_modules, no npm dependency tree to patch and audit. For a security portfolio, the blog itself should be as defensible as the work it documents. It builds to plain static files, so serving is trivial; the trade-off is owning uptime and patching, which for this use case is a feature. ...
