# UpSnap - Wake on LAN Web App
# ============================================
# https://github.com/seriousm4x/UpSnap
# Image: ghcr.io/seriousm4x/upsnap
#
# Access: https://upsnap.dooplex.hu (Authentik OIDC login)
#         https://upsnap.home (internal)
#
# IMPORTANT: UpSnap needs hostNetwork to send magic packets (WoL)
# on the local LAN. This means it binds directly to the host's
# network stack on port 8090.
#
# SSO Setup (Native OIDC via PocketBase):
# UpSnap uses PocketBase under the hood, which supports OIDC natively.
# After first deployment:
# 1. Open https://upsnap.dooplex.hu/_/#/settings/auth-providers
# 2. Select "OpenID Connect (oidc)" and fill in:
#    - Client ID: (from Authentik provider)
#    - Client Secret: (from Authentik provider)
#    - Auth URL: https://authentik.dooplex.hu/application/o/authorize/
#    - Token URL: https://authentik.dooplex.hu/application/o/token/
#    - User API URL: https://authentik.dooplex.hu/application/o/userinfo/
# 3. Create an OAuth2/OIDC Provider in Authentik:
#    - Name: UpSnap
#    - Authorization flow: default-provider-authorization-implicit-consent
#    - Redirect URI: https://upsnap.dooplex.hu/api/oauth2-redirect
#    - Scopes: openid email profile
# 4. Create an Application in Authentik:
#    - Name: UpSnap
#    - Slug: upsnap
#    - Provider: UpSnap
#
# CAUTION: Do not enable/disable auth methods in PocketBase settings
# (other than OIDC). This can cause DB migrations that conflict with updates.
#
# Post-deploy:
# 1. Visit https://upsnap.dooplex.hu and create admin account
# 2. Configure OIDC as above
# 3. Add workstation device (IP + MAC address)
# 4. Optionally configure shutdown command:
#    sshpass -p "$PASSWORD" ssh -o "StrictHostKeyChecking=no" user@IP "shutdown /s /t 0"
