Two replicas with cache=ispn, clustered through Keycloak's default jdbc-ping stack: discovery runs over the PostgreSQL that is there anyway, so no headless Service and no JGroups wiring. Deployment rather than StatefulSet - Keycloak 26 keeps everything in the database, user sessions included. The chart's defining property is that it has TWO INIT CONTAINERS and needs both. db, health-enabled and metrics-enabled are Keycloak BUILD options (verified in the 26.8.0 option table), the published image is augmented with their defaults, and supplying different ones at runtime makes Keycloak rewrite /opt/keycloak/lib/quarkus at start - which readOnlyRootFilesystem: true forbids and which upstream describes as a start that "creates an image that is mutable". Not setting db is no way out: the probes alone force it, because health-enabled is a build option too. An empty emptyDir over that path fails as well, because QuarkusEntryPoint loads quarkus/quarkus-application.dat before it dispatches any command, `build` included. So one init container seeds the directory into a volume, the next runs `kc.sh build` into it, and the serving container runs `start --optimized` - every container keeping the full hardening baseline, with no documented deviation to carry. Build options therefore exist in exactly one place, and the asymmetry is enforced rather than trusted: the serving container passes no build option at all, and a build option's variable name in keycloak.env fails the render with a message naming it. Hostname handling is the security-relevant part. KC_HOSTNAME is derived from ingress.domain as a full URL (which upstream requires alongside hostname-admin), hostname-strict stays at its default true, and proxy-headers is set rather than optional. The admin hostname is NOT presented as an access control: upstream states that hostname-admin "does not prevent accessing the Administration REST API endpoints via the frontend URL specified by the hostname option", so the chart renders no /admin deny rule and values.yaml, NOTES.txt and the wiki all say in the same words that restricting that API is reverse-proxy work. The management port 9000 is a containerPort and a ClusterIP Service for in-cluster scraping, and is in no Ingress: it serves /health/* and optionally /metrics without authentication. Liveness uses /health/live and deliberately not /health or /health/ready - those include the database, and a liveness probe on them would restart the whole cluster for as long as the database is away. Also in this change: - First PodDisruptionBudget in this repository, which makes it a convention (README section 11): minAvailable as a value, and rendered only while the computed replica count is >= 2, because minAvailable: 1 with one replica blocks every node drain forever with a message that names the PDB rather than the replica count. - First quay.io image, so quay.io joins the trusted registries in ci/trivy/data/ksv0125.yaml - configured rather than suppressed, so AVD-KSV-0125 keeps being able to say something. - Renovate block with NO version constraint, which is the counter-case to garage and stalwart and is measured rather than assumed: docker versioning already excludes the -N rebuild tags, the floating minors and latest/nightly. Three dry-run fixtures are recorded at the block, and against the committed config 26.7.4 offers exactly 26.7.5 (patch) and 26.8.0 (minor). - No automerge exception, by decision (Gitea #83): the global automerge applies, and the minor-upgrade procedure plus `kc.sh update-compatibility` is documented in NOTES.txt instead. - Two upstream defaults deviated from, each with its reason at the value: db-pool-max-size 20 instead of 100 (two replicas at 100 ask a default PostgreSQL for twice its max_connections), and uid 1000 / gid 0 instead of this repo's 20000/1000, because the image declares keycloak:x:1000:0 and chowns its install tree to that pair.
