# Standalone observability stack: OpenObserve (storage/search/UI) + Fluent Bit (collector).
#
# Runs independently of ForkFolio so any number of apps on this Docker host can
# ship logs here. Fluent Bit tails every container's json-file log and routes
# containers that set a logging "tag" to a matching OpenObserve stream.
#
# Usage:
#   cp .env.example .env   # then set a strong password
#   docker compose up -d
#   open http://localhost:5080
