New stack:
- stacks/oauth2-proxy/ — per-app sidecars (mlflow, portainer, rabbitmq)
that gate vhosts via nginx auth_request against Keycloak's wbd realm.
Native OIDC wired into:
- grafana (generic_oauth, role-attribute-path → Admin/Editor/Viewer)
- jupyterhub (oauthenticator.GenericOAuthenticator)
- node-red (passport-openidconnect; in-memory state store + users()
resolver because adminAuth doesn't expose req.session)
- jenkins (oic-auth plugin via JCasC; matrix-auth for authz; setup
wizard suppressed; custom image with plugins.txt)
Infra fixes uncovered while bringing the above online:
- nginx-proxy: bump proxy_buffer_size to 16k so oauth2-proxy callbacks
don't 502 on the JWT-bearing Set-Cookie header.
- nginx-proxy: add `resolver 127.0.0.11 valid=30s` so service names
re-resolve after sidecar recreates (was cross-wiring oauth2-proxy
upstreams after restart).
- jupyterhub: pass --allow-root to the singleuser spawner (hub runs as
root inside its container; jupyter-server refused root without flag).
- jupyterhub Dockerfile: install jupyterlab + notebook so
SimpleLocalProcessSpawner has something to launch.
- node-red Dockerfile: install passport-openidconnect into the image
so settings.js can require() it.
- portainer: pre-seed local admin via --admin-password=<bcrypt-hash>
so the 5-minute "no admin → lockout" timer can never trigger.
- deploy.sh: restore executable bit (was 644 in repo).
Admin/viewer policy:
- Created realm role `app-admin` in keycloak wbd realm.
- Grafana maps app-admin → Admin (default Viewer).
- Jenkins matrix-auth grants r.de.ren Overall/Administer, authenticated
users get Overall/Read + Job/Read + View/Read.
- Node-RED: NODERED_ADMIN_USERS env list → permissions "*", others
["read"]. (TODO: switch to app-admin realm role.)
- JupyterHub: JUPYTERHUB_ADMIN_USERS env list. (Same TODO.)
- Gitea: r.de.ren pre-created as local admin; OIDC auto-links via email.
Docs:
- README, cloud/README, stacks/oauth2-proxy/README, and per-stack
READMEs updated to reflect the new state and remove resolved TODOs.
- cloud/.env.example gains all the new OIDC client + cookie-secret keys.
- cloud/README documents the full kcadm realm bootstrap, including the
hardcoded-audience mapper and post-logout redirect URIs that are
non-obvious gotchas.

grafana
Dashboard UI. Cloud-side = central observability. Edge-side = plant-local SCADA.
- Networks:
app(reachable from nginx-proxy) +data(queries influxdb) - Volume:
grafana-data(sqlite, plugins, sessions) - Config:
./config/provisioning(datasources + dashboards as code) — add once SQL/Influx are wired - Hostname:
dash.wbd-rd.nl
Auth
Keycloak OIDC via Grafana's generic_oauth provider. All env-driven (see cloud/.env.example):
| Env var | Purpose |
|---|---|
GRAFANA_OAUTH_CLIENT_ID / _SECRET |
Keycloak grafana client credentials |
GF_AUTH_GENERIC_OAUTH_* |
Provider URLs + claim mapping (set inline in compose.yml) |
Role mapping
GF_AUTH_GENERIC_OAUTH_ROLE_ATTRIBUTE_PATH interprets the Keycloak realm_access.roles claim:
| Keycloak realm role | Grafana org role |
|---|---|
app-admin or grafana-admin |
Admin |
grafana-editor |
Editor |
| (none of the above) | Viewer |
So a fresh teammate added to the wbd realm lands as a Viewer. Grant them app-admin (or grafana-editor) in Keycloak to promote.
GF_AUTH_GENERIC_OAUTH_ALLOW_SIGN_UP=true auto-creates the Grafana user on first OIDC login.
TODO
- Datasource provisioning (
./config/provisioning/datasources/— Influx, postgres) - Dashboard-as-code baseline (
./config/provisioning/dashboards/) - Plugin pin list
