jakman85andClaude Opus 5 0fee584e3a feat(plex): opt into hardware.gpu: intel-quicksync, and write the runbook for the step GitOps cannot reach

Plex has been transcoding in software on hardware that can do it in the iGPU. This
opts its ServiceDefinition into the `hardware` capability from #27 and re-renders.

catalog/plex.yaml gains four lines of YAML and the comment that explains them:

    hardware:
      gpu: intel-quicksync

which renders exactly two things into apps/wave-0/plex.yaml and nothing else — a
`dri` hostPath volume (/dev/dri, type: DirectoryOrCreate) and a read-write /dev/dri
volumeMount on the app container. Whole-tree render diff: 6 added lines, one file.

The comment records what is not obvious from the four lines: the device exists on
ALL THREE prod nodes with i915 bound (so no nodeSelector is rendered and none is
wanted); why `supplementalGroups` would be INERT rather than a hardening (the
image's cont-init hook adds the plex user to the device's group inside the
container, and s6-setuidgid then REPLACES the process group list from /etc/group,
discarding anything Kubernetes supplied); and why `DirectoryOrCreate` is
load-bearing (apps-wave-0 is wait:true with apps-wave-1 depending on it, so a
failed mount would stall the whole app tier for a feature that is not).

THE FEATURE IS INERT UNTIL A HUMAN CLICKS A BOX, and that is the part this commit
is really about. Mounting the device does not enable hardware transcoding; Plex's
`HardwareAcceleratedCodecs` preference does, and it is ABSENT from Preferences.xml
— the toggle has never been on. It cannot be automated: a bounded grep across the
running image's entire init surface (/etc/cont-init.d, /etc/services.d,
/etc/fix-attrs.d, /plex-common.sh, /usr/local/bin) found ZERO PLEX_PREFERENCE*
support, and the six setPref keys the image does write are all unrelated. So
runbooks/plex-quicksync.md is the procedure, registered in the configMapGenerator
(a runbook in git with no generator entry is reviewed, merged, and still a 404) and
indexed in runbooks/README.md. It covers the GitOps/manual boundary, the toggle and
the real preference keys (including the widely-cited one that does not exist and
the upstream misspelling nobody should "fix"), verification via `Transcode (hw)` on
the Plex dashboard — stated plainly as the ONLY proof, because Plex renders no
ServiceMonitor and an alert could never fire — the device-cgroup failure to expect
first with its Intel-device-plugin fallback, and the floating-`:latest` caveat.

Stacked on #27 (feat/sd-hardware-capability), which is open and unmerged; that
branch's commit is in this range by design and this must merge after it.

NOT VERIFIED, and the handoff says so at length: hardware transcoding has not been
observed working. Whether containerd's device cgroup lets a non-privileged pod
open() a bind-mounted char device is an open question that only deploying settles,
and the Plex-side toggle was still unset at the time of writing. A green gate
proves the manifest renders; it proves nothing about transcoding.

Gate (pinned toolbox, worktree): rc 3 — UNDETERMINED, not green. Passed:
decisions-log, lint, l0, render-golden, l1, approval-policy. Skipped (the known
local ceiling): spec-immutability (no sibling spec repo), gitea-settings (no
SETTINGS_API_TOKEN), conformance (CLUSTER_AVAILABLE unset, so L2/L3 did not run).
No fourth skip, nothing failed.

refactor(apps): split monolithic apps Kustomization into dependency waves

2026-08-26 12:19:00 -05:00

README.md

apps

App-tier manifests, rendered from catalog/*.yaml ServiceDefinitions by catalog/render.py and split into dependency-ordered waves (wave-<N>/).

Each wave-<N>/ is reconciled by its own Flux Kustomization apps-wave-<N> (clusters/base/apps-wave-<N>.yaml), which dependsOn wave N-1 (wave 0 dependsOn platform-config) and health-gates (wait: true) ONLY that wave. A crashlooping workload in a later wave can no longer stall an earlier wave or block new revisions.
wave-<N>/kustomization.yaml and clusters/base/apps-wave-<N>.yaml are generated — run python3 catalog/render.py --emit-waves after onboarding a service; do not hand-edit them.
Wave assignment = longest dependency-path depth over the catalog dependencies: graph; a co-located CNPG database <svc>-db is a leaf and always lands strictly below its consumer.

See ../DESIGN-waves.md for the wave table, Flux topology, and the cutover runbook.
