# This makefile is intended to aid on running soledad docker images for
# specific purposes, as running a server, a client or tests.
#
# In order to communicate the IP address of one container to another, we make
# use of a file containing the container id. You have to explicitelly pass the
# CONTAINER_ID_FILE variable when invoking some of the targets below.
#
# Example usage:
#
#   make run-server CONTAINER_ID_FILE=/tmp/container-id.txt
#   make run-client-perf CONTAINER_ID_FILE=/tmp/container-id.txt
