# Felhom Hub — Multi-customer dashboard
# Dashboard: https://hub.felhom.eu
# API: POST /api/v1/report (Bearer token auth)
#
# Receives health reports from customer controllers and displays
# a centralized overview dashboard for the operator (Viktor).
#
# Namespace: felhom-system (shared with healthchecks and other felhom infra)
#
# PREREQUISITES:
#   1. Build and push the hub image:
#        cd ~/build/felhom-hub && ./build.sh v0.2.0 --push
#
#   2. Generate a bcrypt password hash for dashboard login:
#        htpasswd -nbBC 10 "" "your-password" | cut -d: -f2
#      Update the ConfigMap password_hash field below.
#
#   3. Generate a report API key (shared secret for controllers):
#        openssl rand -hex 32
#      Update the ConfigMap report_api_key field below.
#      Then add the same key to each customer's controller.yaml:
#        hub:
#          enabled: true
#          url: "https://hub.felhom.eu"
#          api_key: "<same-key>"
#
#   4. Apply this manifest:
#        kubectl apply -f manifests/hub.yaml
#
#   5. Configure DNS:
#      Add hub.felhom.eu → k3s cluster IP in Cloudflare
#
# DEBUGGING:
#   kubectl logs -n felhom-system deploy/hub -f
#   kubectl exec -it -n felhom-system deploy/hub -- ls /data/
#   kubectl describe ingress -n felhom-system hub
