# docker compose file for running a Citus cluster
# with 3-node etcd v3 cluster as the DCS and one haproxy node.
# The Citus cluster has a coordinator (3 nodes)
# and two worker clusters (2 nodes).
#
# Before starting it up you need to build the docker image:
# $ docker build -f Dockerfile.citus -t patroni-citus .
# The cluster could be started as:
# $ docker-compose -f docker-compose-citus.yml up -d
# You can read more about it in the:
# https://github.com/zalando/patroni/blob/master/docker/README.md#citus-cluster
