CTO Agent 56e598f66c fix(harbor): set updateStrategy=Recreate for RWO PVC rollouts 
Harbor's jobservice and registry Deployments have RWO PVCs (Hetzner
Cloud Volumes). The default RollingUpdate strategy deadlocks: the new
pod cannot attach the volume while the old pod still holds it on a
different node. This has left the harbor Argo CD Application in a
Degraded state since 2026-08-07.

The goharbor chart exposes a top-level updateStrategy specifically for
this case ("Set it as Recreate when RWM for volumes isn't supported").

Refs DEV-458.

Harbor Container Registry

Harbor is deployed at https://harbor.basicstack.de

Initial Access

The initial admin credentials are stored in the harbor-secrets sealed secret:

  • Username: admin
  • Password: Retrieved from secret key harborAdminPassword

OIDC Authentication Setup

Harbor requires OIDC to be configured via the web UI or API after initial deployment. The Helm chart does not support OIDC configuration at deployment time.

Steps to Configure Pocket ID OIDC

  1. Create OIDC Client in Pocket ID

    • Navigate to https://auth.basicstack.de
    • Create a new client with these settings:
      • Client ID: harbor
      • Redirect URIs: https://harbor.basicstack.de/c/oidc/callback
      • Scopes: openid, profile, email, groups
    • Save the client secret

  2. Configure OIDC in Harbor

    • Log in to Harbor as admin: https://harbor.basicstack.de
    • Navigate to: Administration → Configuration → Authentication
    • Select OIDC as the authentication mode
    • Fill in the following:
      • OIDC Provider Name: PocketID
      • OIDC Endpoint: https://auth.basicstack.de
      • OIDC Client ID: harbor
      • OIDC Client Secret: (paste the secret from Pocket ID)
      • Group Claim Name: groups
      • OIDC Admin Group: admins
      • OIDC Scope: openid,profile,email,groups
      • Verify Certificate: ✓ (enabled)
      • Automatic onboarding: ✓ (enabled)
      • Username Claim: email
    • Click Test OIDC Server to verify connectivity
    • Click Save to apply the configuration

  3. Test OIDC Login

    • Log out of Harbor
    • Return to the Harbor login page
    • You should now see a "Login via OIDC Provider" button
    • Click it to authenticate via Pocket ID

Reference Documentation

Storage

Harbor uses encrypted Hetzner Cloud volumes for persistence:

  • Registry data: 50Gi
  • PostgreSQL database: 10Gi
  • Redis cache: 5Gi
  • Trivy vulnerability database: 5Gi
  • Job service logs: 5Gi

All PVCs are configured with resourcePolicy: keep to prevent data loss during upgrades.

Architecture

  • Ingress: Traefik with Let's Encrypt TLS certificates
  • Database: Internal PostgreSQL
  • Cache: Internal Redis
  • Vulnerability Scanning: Trivy enabled
  • Authentication: OIDC via Pocket ID (after manual configuration)
