rezervovator/deploy/docker-compose.yml

# Shared infrastructure for running one Rezervovator container per customer:
# the reverse proxy and the PostgreSQL server. Customer containers are not listed
# here, they are created with ./rezervator.sh (see README.md in this directory).
#
# Both services are optional and selected by profiles: ./rezervator.sh init starts
# "traefik" unless REZERVATOR_PROXY=nginx, and "postgres" unless REZERVATOR_POSTGRES=host.
