Add Crafty Controller 4 (registry.gitlab.com/crafty-controller/crafty-4:4.10.8)
as a platform component: a web panel that runs Java + Bedrock Minecraft servers as
subprocesses in one pod + a 20Gi Longhorn PVC (mounted 5x by subPath).
Auth = Option B (per-app oauth2-proxy reverse-proxy sidecar), since Cilium 1.16.5
cannot do ext_authz on the shared Gateway:
- oauth2-proxy v7.8.1 sidecar (:4180) reverse-proxies to Crafty's self-signed HTTPS
UI (127.0.0.1:8443), gated to Keycloak homelab realm group platform-admins.
- Confidential `crafty` client provisioned live via kcadm + captured in the realm
import; client secret + cookie secret via SOPS/age (mirrored in realm-clients).
- Web UI: HTTPRoute crafty.home.keithjackson.dev -> Service :80 -> sidecar :4180.
- Game ports: Cilium L2 LoadBalancer on VIP 192.168.1.55 (next free after .53/.54),
starter set TCP 25565-25567 (Java) + UDP 19132-19134 (Bedrock), NOT auth-gated.
- fsGroup:0 / runAsGroup:0 / runAsUser:1000 for the image's crafty:root identity on
the root:root Longhorn PVC (the seerr fsGroup lesson).
- Own non-gating Flux tier clusters/base/crafty.yaml (dependsOn platform-config,
wait:false) + sops-decryption patch in clusters/dev — a leaf UI must never gate
the platform.
- Explicit default-deny NetworkPolicy + CiliumNetworkPolicies (platform namespace,
not app-namespace, so Kyverno does not auto-generate the baseline).
make -C ci gate green; kustomize build of platform/crafty, clusters/base,
clusters/dev clean.

Deploy Homepage (gethomepage) as the apex landing dashboard aggregating
links to cluster services, in its OWN non-gating post-platform Flux
Kustomization (clusters/base/homepage.yaml, dependsOn platform-config,
wait:false) — mirrors headlamp/oauth2-proxy so a leaf UI can never gate
the platform chain.
- platform/homepage/: plain manifests (ns, config ConfigMap, Deployment,
Service, default-deny+Cilium ingress NP, apex HTTPRoute). Non-root pod,
HOMEPAGE_ALLOWED_HOSTS, bundled mdi-* icons (DNS-only egress).
- gateway.yaml: add https-apex + http-apex-redirect listeners for the bare
apex (the *.home wildcard listener does NOT match it). Apex is already a
SAN on the wildcard cert — no new Certificate.
- Forward-auth annotated (auth-mode=forward-auth) but NOT enforced: the
Gateway ext-authz mechanism is an unbuilt Phase-6 WS-NET TODO (same status
as all other forward-auth apps). Flagged as PM follow-up.
Gate: lint/l0/render-golden(10/10)/l1 green; conformance skipped (no cluster).

Headlamp's HelmRelease sat in the wait:true `platform` Flux tier. Its pod
crashlooped (`flag provided but not defined: -session-ttl` — chart 0.40.1
renders a container arg the appVersion v0.40.1 backend lacks; upstream
kubernetes-sigs/headlamp#4883), and because it gated `platform`, the whole
chain stalled: platform Ready=Unknown -> platform-config, oauth2-proxy,
apps-wave-0/1/2 and apps-vms all Ready=False "dependency not ready".
Part A (unblock + durable lesson): a leaf UI must never gate the chain. Move
all Headlamp resources into a new non-gating Flux Kustomization
clusters/base/headlamp.yaml (dependsOn platform-config, wait:false, SOPS
decryption patched per-env in clusters/dev) — mirroring oauth2-proxy exactly.
The new Kustomization owns the whole platform/headlamp component; its HTTPRoute
moves from platform-config into platform/headlamp/kustomization.yaml. Removed
headlamp from platform/kustomization.yaml and its httproute from
platform-config/kustomization.yaml. Now a crashlooping Headlamp can never stall
platform/platform-config/apps.
Part B (make it start): pin the chart to 0.41.0 (`>=0.41.0 <0.42.0`). The
backend added `f.Int("session-ttl", …)` in v0.41.0 and chart 0.41.0 pins that
same image (appVersion == chart version), so chart+image realign; every arg the
chart renders for our values is supported. OIDC config + per-user RBAC
(clusterRoleBinding.create:false) unchanged.
Gate: `make -C ci gate` PASS.

oauth2-proxy is a leaf forward-auth service that depends on Keycloak +
trusted wildcard TLS + split-horizon DNS. It lived in the gating `platform`
Flux Kustomization (wait:true), so on a cold start it Failed until those
dependencies existed, keeping the whole `platform` tier not-Ready. That in
turn blocked `platform-config` — which brings up the very Keycloak instance,
wildcard Certificate and L2 VIP oauth2-proxy needs (and previously carried
oauth2-proxy's own httproute/servicemonitor) — from ever reconciling. A
self-gating cold-start deadlock, twice-proven (DECISIONS-LOG sessions 7 & 9).
Break the cycle by moving the whole oauth2-proxy component out of the
`platform` tier into its own non-gating post-platform Flux Kustomization:
- clusters/base/oauth2-proxy.yaml: new Kustomization -> ./platform/oauth2-proxy,
dependsOn platform-config, wait:false, substituteFrom cluster-vars.
- clusters/base/kustomization.yaml: reference the new Kustomization.
- platform/kustomization.yaml: drop the oauth2-proxy component (no longer in
the gating tier).
- platform/oauth2-proxy/kustomization.yaml: pull in httproute + servicemonitor
so the full component travels together.
- platform-config/kustomization.yaml: drop the in-place oauth2-proxy
httproute/servicemonitor refs (moved with the controller).
- clusters/dev/kustomization.yaml: add the SOPS decryption patch for the new
oauth2-proxy Kustomization (it now owns the encrypted credentials Secret that
the `platform` Kustomization used to decrypt).
Now `platform` reaches Ready without oauth2-proxy; platform-config brings up
Keycloak/TLS/DNS; then oauth2-proxy reconciles against dependencies that
already exist. wait:false guarantees its health can never gate anything above
it. No config of oauth2-proxy itself changed — only its reconciliation tier.

First KubeVirt VM app + first real CDI http import. UniFi OS Server (UOS) is
Ubiquiti's current self-host product (the .deb is deprecated); it bundles UniFi
OS + Network app + its own datastore, so no MongoDB companion.
- apps/vms/unifi: CDI DataVolume (Ubuntu 24.04 cloud image -> longhorn-vm
RWX/Block, live-migratable) + VirtualMachine (evictionStrategy: LiveMigrate)
with cloud-init that installs podman/slirp4netns/jq and runs the UOS installer
NON-INTERACTIVELY. The installer URL is resolved at boot from Ubiquiti's public
firmware API (fw-update.ui.com/api/firmware-latest) — always-latest, no pinned
URL to maintain (currently UOS v5.1.37).
- L4 exposure: two LoadBalancer Services (TCP+UDP) sharing a pinned, L2-announced
Cilium VIP 192.168.1.54 (device inform/adoption + STUN can't ride the L7
Gateway); external-dns publishes unifi.home.keithjackson.dev. UI on :11443.
- default-deny + additive CNPs (controller ingress, egress, and CDI-importer
egress for the image pull).
- clusters/base/apps-vms.yaml: NON-GATING Flux Kustomization (wait:false,
dependsOn platform-config) — VMs are a separate lifecycle from the app waves,
so a slow VM import/install can't stall the app tier.

Replaces the single `apps` Flux Kustomization with dependency-ordered waves
(apps-wave-0..2) so a crashlooping workload isolates to its wave + downstream
instead of stalling the entire app tier. Parallel within a wave, ordered across.
- catalog/render.py: compute waves by longest dependency-path depth over the
ServiceDefinition `dependencies:` edges (a `<svc>-db` is a leaf, so its
consumer lands strictly higher — the "DB below consumer" rule falls out of
longest-path, no special case). `--emit-waves` generates the per-wave
kustomizations + Flux CRs; `--wave-layout` places renders into the right dir.
wave 0: pihole gitea jackett plex qbittorrent nextcloud-db semaphore-db
wave 1: sonarr radarr nextcloud semaphore gitea-actions
wave 2: seerr
- apps/*.yaml -> apps/wave-{0,1,2}/ (byte-identical moves; SOPS files intact).
- clusters/base: apps.yaml removed; apps-wave-{0,1,2}.yaml added (dependsOn
chain: platform-config -> wave-0 -> wave-1 -> wave-2, prune+wait each).
- clusters/dev: one SOPS decryption patch per wave (load-bearing).
- DESIGN-waves.md: wave table, topology, cutover runbook.
Cutover: preceded by disabling prune on `apps` (1bfb0db) so removing that
object here does not GC its resources; the wave Kustomizations SSA-adopt the
byte-identical manifests in place (no restart, no PVC churn).

Un-suspend deadlocked: the single platform Kustomization applies HelmReleases
(which register CRDs) AND custom resources of those CRDs (ClusterIssuer,
Certificate, Kyverno ClusterPolicies) in ONE pass. Flux's server-side apply
fails atomically ('no matches for kind ClusterIssuer') → nothing installs, so
the CRD-registering HelmReleases never run either. Classic ordering deadlock.
Fix (flux2 controllers/configs pattern, applies to dev+prod equally — no
R-ENV-02 divergence): add a platform-config Flux Kustomization (dependsOn
platform, wait) carrying the CRs; platform keeps only the controllers.
- New clusters/base/platform-config.yaml (path ./platform-config, substituteFrom
cluster-vars, no decryption — no SOPS content); wired into base + apps now
dependsOn platform-config (transitively waits for platform).
- platform-config/ references the CR files IN PLACE via ../platform/... (Flux
builds LoadRestrictionsNone; Kyverno policies must stay under platform/kyverno/
for the CI L0 gate). CR resources dropped from the platform
component kustomizations (cert-manager, gateway, kyverno).
- Authored the missing Cilium L2 resources (were only a TODO): CiliumLoadBalancerIPPool
(dev NAT 10.73.0.240-.250) + CiliumL2AnnouncementPolicy (ens*), so Gateway
LoadBalancer listeners get a VIP. Prod range must be parameterized later.
Verified: platform build has zero CRs; platform-config build has 2 ClusterIssuers,
6 ClusterPolicies, Certificate, Gateway, both Cilium L2 CRs; dev/prod build; gate PASS.
