# syntax=docker/dockerfile:1

# aquatic_ws
#
# WORK IN PROGRESS: currently has issues spawning worker threads, possibly
# related to https://github.com/DataDog/glommio/issues/547
#
# Customize by setting CONFIG_FILE_CONTENTS and
# ACCESS_LIST_CONTENTS environment variables.
#
# If no changes are made to configuration, aquatic_ws is run:
# - on port 3000
# - without TLS
# - with http health checks enabled
# - only allowing announces for hashes in access list, e.g., contained
#   in ACCESS_LIST_CONTENTS env var
#
# Run from root directory of aquatic repository with:
# $ DOCKER_BUILDKIT=1 docker build -t aquatic-ws -f docker/aquatic_ws.Dockerfile .
# $ docker run -it --ulimit memlock=65536:65536 -p 0.0.0.0:3000:3000 --name aquatic-ws aquatic-ws
#
# Pass --network="host" to run command for much better performance.
