# MediathekNext — Docker Compose
#
# Three deployment patterns:
#
#   1. Standalone (default, single-machine):
#        docker compose up standalone
#
#   2. Scaled-out (core + N workers):
#        docker compose up core worker
#        docker compose up core --scale worker=3
#
#   3. Full stack with observability:
#        docker compose --profile observability up core worker
