Two IPFS Clusters and IPFS daemons on docker-compose.yml

docker-compose.yml

version: '3.4'

# This is an example docker-compose file for IPFS Cluster
# It runs two Cluster peers (cluster0, cluster1) attached to two
# IPFS daemons (ipfs0, ipfs1).
#
# It expects a "compose" subfolder as follows where it will store configurations
# and states permanently:
#
# compose/
# |-- cluster0
# |-- cluster1
# |-- ipfs0
# |-- ipfs1
#
# 
# During the first start, default configurations are created for all peers.
