# Radicale - Naptár és névjegyek (CalDAV / CardDAV szerver)
# Domain: ${SUBDOMAIN}.${DOMAIN}
# Database: None (file-based — every calendar and address book is a folder of .ics/.vcf files)
# RAM: ~40M (mem_limit: 128M) | Pi-compatible: Yes (amd64, arm64, arm/v7)
#
# Environment variables:
#   DOMAIN             - Your domain (e.g., demo-felhom.eu)
#   RADICALE_USER      - A bejelentkezési név (az űrlapon megadható, alapból "csalad")
#   RADICALE_PASSWORD  - A jelszó (telepítéskor generálva, az alkalmazás oldalán látható)
#
# The upstream image (ghcr.io/kozea/radicale, the Radicale project's own) ships NO config, and Radicale 3's
# default `auth type` is `denyall` — nobody can log in. So the start command writes the login file from the
# box's generated password (bcrypt, 0600, on the data volume) ON THE FIRST START ONLY, then starts Radicale with
# htpasswd auth. There is never a moment without a login (no install window, checklist 3.5). The password is
# read from the environment, never pasted into program code (checklist 3.8).
# FIRST START ONLY, measured 2026-10-01 on 9202: the box never puts a `type: password` value into a backup (an
# internet-reachable login; controller `PortableSecretEnvVars`) and makes a NEW one on a restore after a remove,
# expecting the app's own login to come back WITH ITS DATA. The first version rewrote the file at every start —
# a remove + restore then replaced the household's login with a value no page shows, and every phone lost its
# calendar. Written once, the login file lives on the data volume and comes back with the calendars.
