A free, open, self-hosted app platform (GNU AGPLv3): one-click app deploys,
Traefik reverse proxy with automatic SSL, rootless Docker support, gluetun
VPN routing, and a web dashboard to manage it all.

Free & open forever to self-host; optional paid hosted services fund it.

# Apps with `build: .` in their docker compose need their Dockerfile +
# source tree to live in the deployed container dir (where compose runs
# from), not just in the install template dir. dockerComposeSetupFile
# only copies the compose itself; this helper covers the rest.
#
# Auto-detect: if a Dockerfile exists in the install dir for the app,
# we copy every file/folder from install→deployed except docker-compose
# variants (already handled) and the .config (per-app config has its
# own copy lifecycle in dockerConfigSetupToContainer).
#
# Idempotent: re-running mirrors the latest install template. Safe to
# call on every install action.
