## Why The logviewer UI gives browser access to the ClickHouse log store (`logreader` user). It must only be reachable by authorized users, so it sits behind an Authentik-gated oauth2-proxy front at https://logviewer.unkin.net, mirroring the arrstack front-door and mediamover/pdbmux gateway patterns. ## Changes - Adds the logviewer Deployment (1 replica, `docker-internal/logviewer:v0.1.0`) reading ClickHouse at `clickhouse-logs` via the existing `clickhouse-logreader` Secret, `/healthz` probes, nonroot securityContext - Adds an oauth2-proxy (quay.io/oauth2-proxy/oauth2-proxy:v7.15.3) front with issuer `https://identity.unkin.net/application/o/logviewer/`, `ak_groups` claim, allowed group `akP-logviewer-admin`, internal-CA trust via the combine-certs initContainer - Syncs kv `kubernetes/namespace/logging/default/oauth-credentials` into the `logviewer-oauth-credentials` Secret via the existing `default` VaultAuth (kv path already seeded; no terraform-vault change needed) - Adds ClusterIP Services for the app and the oauth2-proxy front door - Adds internal Gateway + HTTPRoutes for `logviewer.unkin.net` (vault-issuer cert, external-dns -> 198.18.200.4, http->https redirect) - Registers `logviewer/` in the logging base kustomization ## Dependency Login requires the Authentik `logviewer` provider/application from terraform-authentik PR #21. This PR is safe to merge first: the VSO secret sync and the deployment come up regardless; OIDC login only works once #21 is applied. Validated with `kustomize build` (base + au-syd1 overlay) and kubeconform (49/49 valid).
