T04 — Phase 3: Deploy privacyIDEA

Phase 3 of NK-WP-0001: deploys the MFA core (privacyIDEA) in the mfa namespace.

Hostnames (config points CP-NK-002 / CP-NK-003):

• pink.coulomb.social — main portal and API
• pink-account.coulomb.social — self-service token portal

Prerequisites:

• T02 complete: mfa namespace and NetworkPolicies applied, cert-manager running.
• T03 complete: PostgreSQL cluster net-kingdom-pg in databases namespace is Ready.
• T01 Phase 0a complete: gen-secrets.sh run, all secrets in KeePassXC.

Apply order

Step 1 — Create the config Secret

cd sso-mfa/k8s/privacyidea
chmod +x create-secrets.sh enckey-bootstrap.sh bootstrap-admin.sh
./create-secrets.sh

Creates privacyidea-config in the mfa namespace (PI_SECRET_KEY, PI_PEPPER, PI_SQLALCHEMY_DATABASE_URI).

---

Step 2 — Apply manifests

# From sso-mfa/k8s/privacyidea/
kubectl apply -f pvc.yaml
kubectl apply -f configmap.yaml
kubectl apply -f middleware.yaml
kubectl apply -f deployment.yaml
kubectl apply -f ingress.yaml

Wait for the pod to reach Running state (DB migrations run on first start — allow up to 3 minutes):

kubectl get pods -n mfa -w
# Expected: privacyidea-<hash>   1/1   Running

If the pod is stuck in Init or CrashLoopBackOff, check logs:

kubectl logs -n mfa -l app.kubernetes.io/name=privacyidea --previous

Common causes:

• privacyidea-config Secret missing → run create-secrets.sh
• PostgreSQL not reachable → verify T03, check NetworkPolicies
• Wrong DB password → re-run create-secrets.sh with corrected secrets

---

Step 3 — Extract key material and create DR Secrets

Run once after the pod reaches Running:

./enckey-bootstrap.sh

This generates RSA audit keys (if not already created), extracts the encryption key and audit keys from the pod, and creates two K8s Secrets as disaster-recovery copies:

• privacyidea-enckey
• privacyidea-auditkeys

Follow the printed instructions to store the key files in KeePassXC, then shred the local copies.

---

Step 4 — Bootstrap admin accounts

./bootstrap-admin.sh

Creates pi-admin (full admin) and trigger-admin (triggerchallenge only). Also creates the privacyidea-trigger-admin K8s Secret used by Keycloak in T05.

Immediately after the script completes:

1. Log in to https://pink.coulomb.social as pi-admin.
2. Navigate to Users → pi-admin → Enroll token and enroll a TOTP or hardware token.
3. Log out, log back in — the MFA challenge must appear.
4. Verify the trigger-admin-rights policy at Config → Policies.

---

Step 5 — Verify

cd sso-mfa/k8s
chmod +x verify-t04.sh
./verify-t04.sh

---

Container port note

The deployment uses containerPort: 8080. The official privacyidea/privacyidea image uses nginx internally; the default nginx port may be 80 depending on the image version.

If the pod starts but requests return "connection refused":

# Check what port the container actually listens on:
kubectl exec -n mfa <pod> -- ss -tlnp | grep LISTEN

If the container uses port 80, update:

1. deployment.yaml: containerPort: 80, Service targetPort: 80
2. sso-mfa/k8s/network-policies/netpol-mfa.yaml: port: 80 in privacyIDEA rules
3. Reapply both files.

---

NetworkPolicy design

privacyIDEA sits entirely behind the NetworkPolicies applied in T02 (netpol-mfa.yaml):

Source	Destination	Port	Purpose
Traefik (kube-system)	privacyIDEA (mfa)	8080	User-facing portal
Keycloak (sso)	privacyIDEA (mfa)	8080	Provider API (triggerchallenge)
privacyIDEA (mfa)	PostgreSQL (databases)	5432	Database

Outbound to anything other than PostgreSQL and kube-dns is denied.

---

Post-deploy steps (after verify-t04.sh passes)

Rate limiting adjustment

The default rate limit (20 req/min, burst 5) is conservative. If Keycloak's triggerchallenge calls trigger false positives (HTTP 429), raise the average in middleware.yaml and reapply. Alternatively, the Keycloak-to-PI path is cluster-internal and not subject to the Ingress middleware.

Admin WebUI IP restriction

Update middleware.yaml privacyidea-admin-allowlist.spec.ipAllowList.sourceRange to your actual VPN/office CIDRs and reapply:

kubectl apply -f middleware.yaml

Self-service portal

Enable the self-service portal policy in privacyIDEA: Config → Policies → New policy:

• Scope: user
• Action: enrollTOTP, enrollHOTP, or token types you want users to manage
• URL for self-service: https://pink-account.coulomb.social

---

Disaster recovery

If the privacyidea-data PVC is lost:

1. Create a new PVC with pvc.yaml.
2. Restore enckey and audit keys from KeePassXC:

   # Copy pi.enc and private/public.pem from KeePassXC into a temporary pod
   kubectl run restore-helper --image=busybox -n mfa --restart=Never -- sleep 3600
   kubectl cp ./pi.enc        mfa/restore-helper:/etc/privacyidea/enckey
   kubectl cp ./private.pem   mfa/restore-helper:/etc/privacyidea/private.pem
   kubectl cp ./public.pem    mfa/restore-helper:/etc/privacyidea/public.pem
   kubectl delete pod -n mfa restore-helper
   

   Or, if the K8s Secrets survived (created by enckey-bootstrap.sh):

   kubectl get secret privacyidea-enckey -n mfa -o jsonpath='{.data.enckey}' | base64 -d > pi.enc
   

3. Restart the privacyIDEA deployment — it will run DB migrations and use the restored key material.
