# docker compose for the @logger/collector server.
#
# Builds the image from ./Dockerfile, which installs @logger/collector from the
# private Verdaccio registry and runs the HTTP ingest/query server on :4319.
#
#   docker compose up -d --build      # build + start
#   docker compose logs -f            # tail logs
#   docker compose ps                 # see health (image defines the probe)
#   docker compose restart            # restart without rebuild
#   docker compose down               # stop, keep the named data volume
#   docker compose down -v            # stop AND wipe stored logs
#
# All knobs default sensibly; override any of them from a .env file or the env:
#   COLLECTOR_VERSION=0.2.2 \
#   REGISTRY=http://host.docker.internal:4873 \
#   COLLECTOR_HOST_PORT=4319 \
#   docker compose up -d --build
#
# NOTE: COLLECTOR_VERSION must match a package actually published to Verdaccio
# (./scripts/publish.sh <version>). If 0.2.2 isn't published yet, publish first
# or point COLLECTOR_VERSION at whatever is on the registry.
