dezky/infrastructure/production/fleet/authentik

fleet/authentik — identity provider (auth.dezky.eu)

Authentik, mirroring the dev docker-compose service but pointed at the in-cluster data tier. Deployed via the k3s Helm controller (helmchart.yaml, which mirrors values.yaml). Live at https://auth.dezky.eu (Let's Encrypt).

• External Postgres (postgres.dezky-data, db/user authentik) + Redis (redis.dezky-data) — chart's bundled subcharts disabled.
• Secrets via global.envFrom → the authentik-secret Secret (generated on-box; see secret.example.yaml). DB/Redis passwords match the dezky-data secrets.
• Ingress: Traefik + cert-manager letsencrypt-prod.
• error_reporting off, update-check off, bootstrap email admin@dezky.eu.

Deploy

# 1. secret (reads DB/Redis pw from dezky-data so they match; rest generated)
ADB=$(kubectl -n dezky-data get secret postgres-secret -o jsonpath='{.data.AUTHENTIK_DB_PASSWORD}' | base64 -d)
RDB=$(kubectl -n dezky-data get secret redis-secret    -o jsonpath='{.data.REDIS_PASSWORD}'        | base64 -d)
kubectl create namespace dezky-auth --dry-run=client -o yaml | kubectl apply -f -
kubectl -n dezky-auth create secret generic authentik-secret \
  --from-literal=AUTHENTIK_SECRET_KEY=$(openssl rand -hex 50) \
  --from-literal=AUTHENTIK_POSTGRESQL__PASSWORD="$ADB" \
  --from-literal=AUTHENTIK_REDIS__PASSWORD="$RDB" \
  --from-literal=AUTHENTIK_BOOTSTRAP_PASSWORD=$(openssl rand -hex 16) \
  --from-literal=AUTHENTIK_BOOTSTRAP_TOKEN=$(openssl rand -hex 32)
# 2. install
kubectl apply -f helmchart.yaml
kubectl -n dezky-auth rollout status deploy/authentik-server --timeout=300s

First login

# akadmin password (store in Bitwarden):
kubectl -n dezky-auth get secret authentik-secret -o jsonpath='{.data.AUTHENTIK_BOOTSTRAP_PASSWORD}' | base64 -d; echo

Log in at https://auth.dezky.eu as akadmin / that password.

TODO (mirror the rest of dev — not yet applied)

• OIDC app blueprints. Dev provisions the operator app + a dezky-platform-admins access policy via a blueprint (infrastructure/docker-compose/configs/authentik/blueprints/). For prod, mount the equivalent at /blueprints/custom with prod redirect URLs (operator.dezky.eu, app.dezky.eu) + the matching client IDs/secrets. The portal OIDC client (hand-made in dev) also needs creating.
• Rebrand ("Powered by authentik" → "Powered by Dezky"): dev runs rebrand-web.sh as a root lifecycle script. Replicating in k8s needs a root-capable initContainer/command override — cosmetic, deferred.
• Pin the chart version (currently latest → app 2026.5.2).
