[区块链]Goland下使用chaincode-docker-devmode调试链码

介绍：该例程已经配置好docker，通过GoLand得docker工具启动容器后，通过CLI安装、实例化和调用链码。

1.克隆fabric-samples

git clone https://github.com/hyperledger/fabric-samples.git

2.使用GoLand打开chaincode-docker-devmode的docker-compose-simple.yaml

version: '2'

services:
  orderer:
    container_name: orderer
    image: hyperledger/fabric-orderer
    environment:
      - FABRIC_LOGGING_SPEC=debug
      - ORDERER_GENERAL_LISTENADDRESS=orderer
      - ORDERER_GENERAL_GENESISMETHOD=file
      - ORDERER_GENERAL_GENESISFILE=orderer.block
      - ORDERER_GENERAL_LOCALMSPID=DEFAULT
      - ORDERER_GENERAL_LOCALMSPDIR=/etc/hyperledger/msp
      - GRPC_TRACE=all=true,
      - GRPC_VERBOSITY=debug
    working_dir: /opt/gopath/src/github.com/hyperledger/fabric
    command: orderer
    volumes:
      - ./msp:/etc/hyperledger/msp
      - ./orderer.block:/etc/hyperledger/fabric/orderer.block
    ports:
      - 7052:7052
      
  peer:
    container_name: peer
    image: hyperledger/fabric-peer
    environment:
      - CORE_PEER_ID=peer
      - CORE_PEER_ADDRESS=peer:7051
      - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer:7051
      - CORE_PEER_LOCALMSPID=DEFAULT
      - CORE_PEER_ADDRESSAUTODETECT=true
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      - FABRIC_LOGGING_SPEC=DEBUG
      - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp
    volumes:
        - /var/run/:/host/var/run/
        - ./msp:/etc/hyperledger/msp
    working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer
    command: peer node start --peer-chaincodedev=true
    ports:
      - 7051:7051
      - 7053:7053
    depends_on:
      - orderer

  cli:
    container_name: cli
    image: hyperledger/fabric-tools
    tty: true
    environment:
      - GOPATH=/opt/gopath
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      - FABRIC_LOGGING_SPEC=DEBUG
      - CORE_PEER_ID=cli
      - CORE_PEER_ADDRESS=peer:7051
      - CORE_PEER_LOCALMSPID=DEFAULT
      - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp

    working_dir: /opt/gopath/src/chaincodedev
    command: /bin/bash -c './script.sh'
    volumes:
        - /var/run/:/host/var/run/
        - ./msp:/etc/hyperledger/msp
        - ./../chaincode:/opt/gopath/src/chaincodedev/chaincode
        - ./:/opt/gopath/src/chaincodedev/
    depends_on:
      - orderer
      - peer
##如果chaincode容器可以顺利开启，则配置正确，然后用用goland得本地运行代替chaincode容器
  chaincode:
    container_name: chaincode
    image: hyperledger/fabric-ccenv
    tty: true
    privileged: true
    environment:
      - GOPATH=/opt/gopath
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      - FABRIC_LOGGING_SPEC=DEBUG
      - CORE_PEER_ID=chaincode
      - CORE_CHAINCODE_ID_NAME=mycc:1
      - CORE_PEER_TLS_ENABLED=false
      - CORE_PEER_ADDRESS=peer:7051
      - CORE_PEER_LOCALMSPID=DEFAULT
      - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp
    working_dir: /opt/gopath/src/chaincode
    command: /bin/sh -c 'sleep 6000000'
    volumes:
        - /var/run/:/host/var/run/
        - ./msp:/etc/hyperledger/msp
        - ../chaincode:/opt/gopath/src/chaincode
    depends_on:
      - orderer
      - peer

3.启动Docker

4.进入CLI终端

##安装链码
peer chaincode install -p chaincode/sacc/  -n mycc -v 1
##如果安装失败就配置代理
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct
##实例化
peer chaincode instantiate -n mycc -v 1 -c '{"Args":["a","10"]}' -C myc

成功后生成链码的运行容器

5.配置链码Debug配置&&运行

以下地址peer容器的ip（进入终端 命令ifconfig查看）
#CORE_CHAINCODE_ID_NAME对应刚刚安装和实例化得链码名称：版本号
#Environment
CORE_PEER_ADDRESS =17*.18.0.*:7051;CORE_CHAINCODE_ID_NAME=mycc:0;CORE_PEER_TLS_ENABLED=false
#Program arguments 
-peer.address 17*.18.0.*:7052

6.设置断点&CLI调用链码

peer chaincode invoke -n mycc -c '{"Args":["set", "a", "30"]}' -C myc

触发断点

如果不行得话先把链码容器关掉
