# Shared infrastructure: identity, storage, database, messaging and tracing
# for every project (Musify, Ping, docker-manager, ...).
#
# This file is the production shape: no published ports, no domains. Every
# service is reachable only on the `infra-net` network. Development reaches
# it through compose.dev.yml, which publishes the ports to the host instead
# of joining a network. See README.md for why.
#
#   dev   docker compose -f compose.yml -f compose.dev.yml up -d
#   prod  docker compose --env-file .env.prod -f compose.yml up -d
#
# A consuming project's own deploy stack does NOT get its own copy of any of
# these services. It only needs this stack to already be up, and its own
# one-shot bootstrap jobs (zitadel-init, seaweedfs-init) to create its own
# OIDC apps / bucket against the shared instances below.

# Docker's default json-file driver never rotates, so logs would grow until
# the disk fills up.
