* feat(youko): add Jellyfin media server
Jellyfin reads the existing Transmission download tree on the public HDD
(via the shared `fileshare` group) and transcodes with the AMD Barceló
iGPU through VA-API. Encoding settings are declared in Nix
(`forceEncodingConfig`), so the web UI cannot silently drift.
Replace the per-service public ACME certificates with a single
`*.writefor.fun` wildcard (plus the apex) shared by every public vhost,
so adding a service needs no new ACME entry; a wildcard also keeps
individual hostnames out of public CT logs.
Pin the jellyfin uid/gid to avoid the dynamic-id drift fixed for the
other services in #320.
* fix(youko): enable graphics for Jellyfin VA-API
VA-API needs Mesa's radeonsi VA driver under /run/opengl-driver, but
youko is headless so hardware.graphics was off. Without it Jellyfin's
ffmpeg fails with 'va_openDriver() returns -1'. Enable it so the iGPU
can be used for hardware transcoding.
* fix(youko): use VA-API hardware encoding for Jellyfin
Enabling hardware decoding alone left encoding on the CPU (libx264), which
pins ~3 cores per 720p stream. Set transcoding.enableHardwareEncoding so
the iGPU (Vega VCN) does the H.264 encode too.
* feat(youko): harden Jellyfin proxy trust, groups, and HEVC encode
Add jellyfin to the render/video groups for robust VA-API access (was
relying on the world-writable render node), enable HEVC hardware encoding
(Vega's VCN supports it; AV1 does not), and patch network.xml on start to
trust Caddy as KnownProxies and advertise the public URL.
* fix(youko): run Jellyfin network.xml patch every start; allow LAN discovery
The module's preStart exits early once encoding.xml matches, so the
mkAfter network.xml patch only ran when encoding settings changed. Run it
with mkBefore instead. Also allow Jellyfin app auto-discovery (UDP 7359 /
TCP 8096) from the home network only.
Service users/groups get a dynamically allocated uid/gid, which shifts when the user set changes: adding `immich` moved gitea 993:985 -> 996:993 and rustfs 987:977 -> 988:983. Files on the persistent volumes keep the old numeric owner, so gitea and rustfs lost access to their data and failed to start after a restart. Pin every dynamically allocated service id on youko to its current value. The ids are host-specific, so this is a host file.
timerConfig was set with lowercase onCalendar/randomizedDelaySec, which systemd treats as unknown directives. The generated timer had no schedule, so `systemctl list-timers` showed NEXT=- and no backup ever ran. Use the real keys OnCalendar/RandomizedDelaySec.
Add Immich via the native nixpkgs services.immich module on youko, reusing the host PostgreSQL 16 (pgvector + vectorchord) and a shared Valkey instance for Redis-compatible caching and BullMQ queues (Dragonfly rejected BullMQ's dynamic Lua keys). Media lives on the encrypted HDD at /data/apps/immich; Caddy publishes immich.writefor.fun with a publicly-trusted Let's Encrypt cert (security.acme + Cloudflare DNS-01) so the mobile app connects. OTEL metrics are scraped by VictoriaMetrics, and /var/cache is now preserved on the tmpfs-root hosts so the ML model cache survives reboots.
The s3-console Caddy vhost redirected every request to / to /rustfs/console/. The RustFS console frontend signs its own S3/STS requests to / (POST / for STS, GET /?x-id=ListBuckets), so the 302 broke the console session and login failed server-side with SignatureDoesNotMatch ("missing signed header: content-type"). Restrict the redirect to unsigned browser GET /; signed requests now reach RustFS unchanged.
Deploy RustFS in place of the retired MinIO and move the S3 consumers over.
- flake.nix / flake.lock / outputs/default.nix: add a nixpkgs-small
(nixos-unstable-small) input for the rustfs 1.0.0 package (with the web
console), instantiated as pkgs-small in genSpecialArgs alongside the other
nixpkgs instances; drop the rustfs flake input. The rest of the system stays
on the default nixpkgs.
- hosts/12kingdoms-youko/homelab-services/rustfs.nix: use nixpkgs' own
services.rustfs module, with package = pkgs-small.rustfs and
environmentFile = the agenix rustfs.env secret.
- caddy.nix: s3.writefor.fun (S3 API) and s3-console.writefor.fun (console,
redirects / to /rustfs/console/).
- secrets/nixos.nix: declare a single rustfs.env (dotenv) secret holding
RUSTFS_ACCESS_KEY / RUSTFS_SECRET_KEY, replacing the separate key files.
- infra/minio -> infra/rustfs: buckets are managed with the hashicorp/aws
provider against the RustFS S3 endpoint; IAM/ILM are applied with rc.
Crush hardcodes banned bash commands, blocking many operations. Drop the package, its AGENTS.md/CRUSH.md install target, env vars, and preservation entries.
Keep the six node configuration intact while removing the failing user activation from the three control-plane MicroVMs. Update the regression test and current K3s configuration notes.
0.156.1 still lacks the codex-chatgpt recursion_limit attribute, so keep the postPatch that adds it. The vendored Cargo.lock is unchanged, so the cargoHash stays the same.
cilium writes /etc/cni/net.d while istio-cni reads k3s's own dir, so on the new workers the chained plugin never found a network config. Add the symlinks the server module already has.
kubelet refuses to self-assign the reserved node-role.kubernetes.io/* labels, so the worker --node-label made the agent crash-loop. Drop it and rely on the masters' control-plane taint for placement; document that the taint only lands via registerWithTaints on first registration, so it was applied by hand here.
- run two autocutsel instances so the X PRIMARY/CLIPBOARD selections stay in
sync, making copy/paste work in the session and through VNC
- drop --disable-blink-features=AutomationControlled: nothing drives the
browser over CDP, so navigator.webdriver is already false and the flag only
marked the setup as automated
- document why the driver stays on real X11/AT-SPI input and is never granted
a CDP attach, and note the SSH-tunnel path for manual VNC access
- extend the computer-use eval test
Add worker-1 (4 vCPU / 16 GiB) on shoryu, and worker-2 (4 vCPU / 16 GiB) plus worker-3 (2 vCPU / 8 GiB) on shushou, as microVMs. They come with a genK3sAgentModule and the per-host/output/home-manager wiring, and are labelled node-role.kubernetes.io/worker=true. The masters keep their control-plane:NoSchedule taint, so workloads land on the workers.
The script pointed the macOS nix-daemon at the homelab v2ray HTTP proxy (192.168.5.101:7890), but that proxy was never running. Remove it together with the just darwin-set-proxy recipe and the README step that referenced it.
Reserve 192.168.5.192/27 as a dedicated kube-vip block, outside the router's DHCP pool (.2-.99): one /29 per cluster, k3s-test-1 gets .192/29 with the API VIP at .193.
Advertise only youko itself (.183/32) and that block over Tailscale, instead of the whole /24. The /24 route shadowed hosts that are already reachable directly, e.g. idols-ai at 192.168.5.100.
Deploy prerequisites (not in this repo): approve the new Tailscale routes; point kube-vip at the new VIP; move the *.writefor.fun wildcard from .101 to .183 and update scripts/darwin_set_proxy.py, since .101 is no longer advertised.
Give the idols-ruby and idols-kana VMs a headless computer-use
environment: Xvfb plus i3, driven by cua-driver (and computer-use-linux
as a fallback). Includes the system module (AT-SPI, fonts, Mesa, Clash
Verge proxy, proxy-region timezone), the home i3 module (Xvfb/i3/x11vnc
services, browser flags), host wiring and an eval test.
Package the prebuilt releases (computer-use-linux v0.7.1 and
cua-driver-rs v0.24.0) under pkgs/, injected through thin callPackage
overlays so they are easy to relocate to the NUR repository later.
Only three secrets are readable as the login user (nix-access-tokens,
ssh-key-romantic and the nushell one); everything else is root-only and
the filesystem already keeps agents out.
* feat(backup): notify on failure, and 404 unconfigured hostnames
A failed backup was silent. Post to alertmanager (which routes above-info
to telegram), and have caddy answer 404 instead of its empty 200 for
*.writefor.fun names that are not services.
* docs(backup): say 'cloud copy' rather than 'offsite'
Clearer for a reader who does not live in backup jargon; the requirement
(not in the homelab, immutable) is spelled out in the text.
* docs(secrets): state the recipient invariant
A recipient set must answer two questions: who may read it, and how it is
recovered once those hosts are gone. Dropping recovery_key while narrowing
a secret is easy and silent.
* docs(secrets): state that every secret must be decryptable by the desktops
The desktops hold the trusted admin keys and are where secrets are edited and
rekeyed from; narrowing a set to the servers alone breaks agenix -r and drops
the offline recovery key.
* docs(secrets): desktops and recovery_key have identical access
recovery_key is a member of desktop_keys, so every group written as
desktop_keys ++ ... covers both.
* feat(monitoring): scrape the restic rest-server
Expose /metrics on the loopback-bound server, scrape it with
victoriametrics, and block /metrics on the public vhost.
* docs(backup): record what the metrics actually expose
rest-server only ships the go/promhttp defaults, so repository growth is
charted from node-exporter's filesystem metrics instead.

A desktop holds both the plaintext and the repository password, so blocking
deletion on the server protects little while preventing the automatic
retention the client needs. Immutability belongs in the offsite copy.
