opensearch.yml

# This docker-compose file launches a minimal opensearch stack:
# - opensearch engine
# - opensearch dashboards
# - logstash
#
# In addition it adds overlay configs to various of the merritt micro-service containers
# to add logging configuration options.  This sets up log indexing for these containers.
