Add Headlamp (kubernetes-sigs/headlamp Helm chart) at headlamp.home.keithjackson.dev with native Keycloak OIDC login and PER-USER RBAC: Headlamp forwards each user's id_token to the k3s apiserver, so the existing oidc:* group bindings (platform-admins->cluster-admin, viewers->view) apply per user. The ServiceAccount is deliberately NOT bound to cluster-admin (clusterRoleBinding.create=false), since user requests ride the forwarded token. Key integration nuance: the apiserver is configured oidc-client-id=kubernetes, so it only accepts tokens whose aud contains `kubernetes`. The new `headlamp` Keycloak client carries an oidc-audience-mapper (included.client.audience= kubernetes) so tokens carry aud=[headlamp, kubernetes] -- accepted by both Headlamp's own verifier and the apiserver, leaving the apiserver config untouched. A groups mapper emits the `groups` claim the apiserver maps to RBAC. - platform/headlamp: namespace, HelmRepository/HelmRelease, SOPS OIDC secret (externalSecret envFrom), default-deny NetworkPolicy + Cilium ingress (gateway)/egress (apiserver+Keycloak) policies, README. Wired into platform/kustomization.yaml (platform tier). - platform/headlamp/httproute.yaml wired into platform-config (Gateway API CR, dependsOn platform), modeled on grafana-httproute. - keycloak-realm-import: add `headlamp` confidential client + groups/audience mappers + HEADLAMP_CLIENT_SECRET placeholder. Client also created LIVE via kcadm (realm import no-ops on the existing realm). - keycloak-realm-clients.sops: add headlamp-client-secret (mirrored into headlamp-oidc-credentials clientSecret). Both encrypted to the repo age key. Co-Authored-By: Claude Opus 4.8 <[email protected]>
