# FileBrowser - Web-based file manager
# https://filebrowser.org/
#
# Features:
# - Web-based file browser and manager
# - File upload/download via web UI
# - File preview (images, text, markdown, video)
# - Built-in text editor
# - Share links for files
# - Very lightweight (~15MB RAM)
# - Authentik SSO integration (proxy auth)
#
# Authentication: Via Authentik (no double login!)
# FileBrowser trusts the X-authentik-username header from the proxy.
#
# Authentik Setup:
# 1. Create a Proxy Provider in Authentik:
#    - Name: FileBrowser
#    - Authorization flow: default-provider-authorization-implicit-consent
#    - Type: Forward auth (single application)
#    - External host: https://webadmin.dooplex.hu
#
# 2. Create an Application:
#    - Name: FileBrowser
#    - Slug: filebrowser
#    - Provider: FileBrowser (the one you just created)
#
# 3. Create an Outpost (or add to existing):
#    - Name: filebrowser-outpost
#    - Type: Proxy
#    - Integration: Kubernetes (auth-system namespace)
#    - Applications: FileBrowser
#
# 4. Authentik will auto-create:
#    - Deployment: ak-outpost-filebrowser-outpost in auth-system
#    - Service: ak-outpost-filebrowser-outpost in auth-system
#    - Ingress for /outpost.goauthentik.io path on webadmin.dooplex.hu
#
# Note: The outpost service name in auth-url must match!
#       If you name outpost differently, update the annotation:
#       http://ak-outpost-<your-outpost-name>.auth-system.svc.cluster.local:9000/...
#
# Access:
# - Admin UI: https://webadmin.dooplex.hu (Authentik login)
# - Public files: https://web.dooplex.hu (direct file access, no auth)
#
# Usage for static HTML hosting:
# 1. Login to webadmin.dooplex.hu (via Authentik)
# 2. Upload HTML files and assets to /public folder
# 3. Access directly via web.dooplex.hu/filename or web.dooplex.hu/folder
#
# Clean URL examples:
# - /public/fizetes.html       → web.dooplex.hu/fizetes
# - /public/fizetes/index.html → web.dooplex.hu/fizetes
# - /public/about/index.html   → web.dooplex.hu/about
#
# Note: First user to login via Authentik becomes admin in FileBrowser.
# Additional users logging in will be created automatically.
