furtka/assets/Caddyfile

# Serves the Furtka landing page + live JSON on :80 (plain HTTP) and :443
# (HTTPS via Caddy's built-in `tls internal` — locally-issued certs signed
# by a root CA that Caddy generates on first start and stores under
# /var/lib/caddy/.local/share/caddy/pki/authorities/local/). Static pages
# are read from /opt/furtka/current/ — updates flip the symlink and
# everything picks up the new content without a Caddy restart (a
# `systemctl reload caddy` is still triggered post-swap to flush the
# file-server's handle cache). /apps and /api are reverse-proxied to the
# resource-manager API (furtka serve, bound to 127.0.0.1:7000).
#
# Force-HTTPS: /etc/caddy/furtka.d/*.caddyfile gets imported into the :80
# block. The /api/furtka/https/force endpoint creates or removes
# redirect.caddyfile there to toggle the HTTP→HTTPS redirect, then reloads
# Caddy. Glob imports silently no-op on an empty/missing directory, so the
# toggle-off state is "no file present" rather than "empty file".
