fabric config文件

Fabric配置文件是一个YAML文件，它定义了Fabric网络中的各种配置参数。以下是一个Fabric配置文件的示例：

version: '2'

networks:
  mynetwork:
    external:
      name: mynetwork

services:
  orderer.example.com:
    image: hyperledger/fabric-orderer
    container_name: orderer.example.com
    command: orderer
    environment:
      - ORDERER_GENERAL_LOGLEVEL=debug
      - ORDERER_GENERAL_LISTENADDRESS=0.0.0.0
      - ORDERER_GENERAL_LISTENPORT=7050
      - ORDERER_GENERAL_GENESISMETHOD=file
      - ORDERER_GENERAL_GENESISFILE=/etc/hyperledger/configtx/genesis.block
      - ORDERER_GENERAL_LOCALMSPID=OrdererMSP
      - ORDERER_GENERAL_LOCALMSPDIR=/etc/hyperledger/msp/orderer/msp
    volumes:
      - ./config/:/etc/hyperledger/configtx
      - ./crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/:/etc/hyperledger/msp/orderer
    ports:
      - 7050:7050
    networks:
      - mynetwork

  peer0.org1.example.com:
    image: hyperledger/fabric-peer
    container_name: peer0.org1.example.com
    environment:
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      - CORE_LOGGING_LEVEL=debug
      - CORE_PEER_ID=peer0.org1.example.com
      - CORE_PEER_ADDRESSAUTODETECT=true
      - CORE_PEER_NETWORKID=mynetwork
      - CORE_PEER_LOCALMSPID=Org1MSP
      - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/peer/
      - CORE_PEER_ADDRESS=peer0.org1.example.com:7051
    volumes:
        - /var/run/:/host/var/run/
        - ./crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp:/etc/hyperledger/msp/peer
        - ./crypto-config/peerOrganizations/org1.example.com/users:/etc/hyperledger/msp/users
    ports:
      - 7051:7051
    depends_on:
      - orderer.example.com
    networks:
      - mynetwork

在上面的示例中，配置文件定义了一个Fabric网络，包括一个Orderer节点和一个Peer节点。Orderer节点使用`hyperledger/fabric-orderer`镜像，Peer节点使用`hyperledger/fabric-peer`镜像。配置文件还定义了节点的环境变量，卷和端口映射等。最后，节点被分配到mynetwork网络中。
