docker-compose.plugins.yml

# Plugin services overlay — OTEL collector/processor.
#
# NOTE: For local development, prefer docker-compose.plugin-stack.yml which is
# self-contained and includes Neo4j with a healthcheck.
#
# Usage (overlay on plugin-stack — recommended for adding to existing stack):
#   # Already included in docker-compose.plugin-stack.yml
#
# Usage (overlay on core template — requires neo4j profile active):
#   docker compose -f docker-compose.template.yml --profile neo4j -f docker-compose.plugins.yml up
#
# Prerequisites:
#   - neo4j service running with healthcheck (docker-compose.plugin-stack.yml provides this)
#   - NEO4J_URI, NEO4J_USERNAME, NEO4J_PASSWORD set in .env
#   - DOMAIN set to your ingress domain (e.g. localhost)
