# Development: the same services as docker-compose.yml, with the repository mounted, automatic
# reload and the Vite dev server. It is an override, always used together with the main file;
# .env.dev.example sets COMPOSE_FILE=docker-compose.yml:docker-compose.dev.yml so that plain
# "docker compose ..." commands act on the development environment. See docs/development.md.
#
# Open http://localhost:${VHS_DEV_HTTP_PORT:-8081} (loopback only): Nginx forwards the API to
# Django (runserver) and everything else to Vite, and serves the protected media, as in
# production. Services reach each other by name inside the Docker network.
#
# Ports and volumes of an override ADD to those of docker-compose.yml, build/image/command
# replace them: "!override" below keeps only what development needs. Check the
# merged configuration with scripts/check-dev-config.sh.
