After multiple attempts to get the network running i created containers which i had to delete with the command docker ps -aq. Also i had to get the network down before that with the command ./byfn.sh -m down. Then i restarted everything by using byfn.sh -m generate -c mychannel and byfn.sh -m up -c mychannel -s couchdb Then everything worked as in the docs described.
