Instructions

Create Docker Swarm cluster

• Create one or more master hosts and other worker hosts
  • Open ports for Swarm. On ALL hosts, (eg, CentOS)

  # if run on local, no need
  firewall-cmd --permanent --zone=public --add-port=2377/tcp --add-port=7946/tcp --add-port=7946/udp --add-port=4789/udp
  firewall-cmd --reload

• I think opening swarm ports only is sufficient because all nodes communicates thru overlay network.

• on master host, If you can not run swarm mode, you must set --live-restore to false in /etc/docker/daemon.json
  For those who can’t find /etc/docker/daemon.json try /etc/sysconfig/docker live-restore option is there: OPTIONS=’–selinux-enabled --log-driver=journald --live-restore’

  docker swarm init

• You can see like below,

  Swarm initialized: current node (dxn1zf6l61qsb1josjja83ngz) is now a manager.

  To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-0q7mhbliu4lp7lehsavwzkv2di8214bvp7d29d33zxbbn6gm88-dz9bdw752l2296ni4ia2nsudk 192.168.65.3:2377

  To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

• Use last command to join worker host to Swarm cluster eg, on worker hosts,

    docker swarm join --token SWMTKN-1-0q7mhbliu4lp7lehsavwzkv2di8214bvp7d29d33zxbbn6gm88-dz9bdw752l2296ni4ia2nsudk 192.168.65.3:2377

Create overlay network

• Create overlay network which will be used as path between hyperledger nodes
  • on Master host,

    docker network create --attachable --driver overlay --subnet=10.200.1.0/24 hyperledger

Download Hyperledger Fabric v1.1 images and Bin:

    curl -sSL http://bit.ly/2ysbOFE | bash -s 1.1.0 1.1.0 0.4.10

• Generate artifacts

  ./generate.sh -c

Se generan todos los certificados de la organización. en carpeta config/ y /crypto-config. Recordar cambiar la ruta del certificado _sk en docker composer del CA. Ejemplo: - FABRIC_CA_SERVER_TLS_KEYFILE=/etc/hyperledger/fabric-ca-server-config/46b93201b21aa6d399adf542dc9f3d890f2c8288c258bb99ad3aaf1dc889146d_sk

• Attach to cli container

  docker exec -it $(docker ps --format "table {{.ID}}" -f "label=com.docker.stack.namespace=hyperledger-cli" | tail -1) bash

• Create a channel

  export CHANNEL_NAME=mychannel
  export ORG=agiletech.vn
  peer channel create -o orderer0.${ORG}:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/$ORG/orderers/orderer0.${ORG}/msp/tlscacerts/tlsca.${ORG}-cert.pem

• Join a channel

  peer channel join -b mychannel.block
  peer channel list

• Install & Initiate Chaincode

  peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/sacc
  peer chaincode instantiate -o orderer0.agiletech.vn:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/agiletech.vn/orderers/orderer0.agiletech.vn/msp/tlscacerts/tlsca.agiletech.vn-cert.pem -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["a", "100"]}'
