Finishes the sizing pass over every workload the deploy actually manages. Each
request is at or above the container's p95 over the last seven days, so nothing
is sized below what it is known to use, and each limit is between 1.6x and 5x
the observed max, which is the figure that decides whether a burst gets an
OOMKill.
Some of these go up, and that is the point. adguard was holding 975M against a
500Mi request and netbox 962M against 512Mi, so both sat permanently above
their own request and were standing eviction candidates on a node that has
about 300M of headroom. Raising a request costs scheduler room; leaving it low
costs the pod its place in the queue when the node gets tight.
Others come down. loki ran with a 2Gi limit on 224M, gitea 1.5Gi on 305M, the
authentik worker 1Gi on 305M, and a tail of single-purpose pods -- redis,
glance, the two homepages, cfddns, session-keeper, the netbird dashboard, the
loki gateway -- each reserved 4x to 16x more than they have ever touched.
prometheus gets the opposite treatment: 768Mi/2560Mi, above its p95, because it
compacts its TSDB in place and that is a burst worth budgeting for rather than
throttling.
Two of these limits are close enough to the observed max to be worth watching
rather than trusting: adguard at 1.5x, and its DNS cache grows monotonically, so
the ceiling is a date, not a margin. That was true before this change too; the
pod sizing does not fix it and the cache needs bounding.
CPU limits are untouched throughout. Leaving postgres alone as well: it sits in
an uncommitted file that belongs to other work in progress.
Verified: every request is at or above p95 and every limit above the observed
max across all 74 containers, and 16/16 local gates pass.
All prod IngressRoutes switch tls.certResolver to tls.secretName
backed by per-router Certificates (HTTP-01, letsencrypt-prod).
adguard-prod reuses the shared adguard-certs secret (also feeds
DoT :853); sync CronJob removed as redundant.
Traefik certificatesResolvers removed: its internal
acme-http@internal router hijacks HTTP-01 for every host while
enabled, blocking external solvers. Dormant files (kener,
downtify) converted for consistency but not applied; n8n
untouched per live-only rule.
Move the shared postgres service from 15.19 to 17.6 as the postgres17 StatefulSet with its own PVC, extend the initdb and ingress policy with the statuspage database, and drop the now-unused per-app postgres manifests for authentik, gitea and netronome.
Protect public Traefik routes with CrowdSec HTTP decisions and restore access logging for web traffic analysis.

services marked k8s/active are applied via kubectl; the rest via docker
compose. inactive services with k8s/ keep only routing manifests
(external Services, EndpointSlices, Ingresses) to reach docker backends.
headscale/nextcloud routing moved to k8s/routing/.
validations: compose config --quiet + kubectl apply --dry-run=client.
namespace manifests applied first. pull_policy:build stacks get
build+push before up so the registry image stays fresh.
