docker-compose-cli.yaml详解（进入cli容器后踩到深坑的我）（orderer容器未正常启动）

先说我踩得什么坑吧
（重新编辑此博客，以前写的太low）

• 配置文件详解
• cli容器中执行遇到的错误

docker-compose-cli.yaml详解：

version: '2'

volumes:   #声明挂载的卷
  orderer.example.com:
  peer0.org1.example.com:
  peer1.org1.example.com:
  peer0.org2.example.com:
  peer1.org2.example.com:

networks:   #声明一个名称为byfn的网络
  byfn:

services:

  orderer.example.com:   #定义一个名称为orderer.example.com的服务
    extends:    #扩展，代表需要加载的文件或服务  即使用了其中的配置信息
      file:   base/docker-compose-base.yaml      
      service: orderer.example.com   
    container_name: orderer.example.com   #当前容器名称
    networks:      #指定当前容器所加入的网络，如果需要加入多个网络，可以定义多个
      - byfn

    #以下同上

cli容器中遇到的错误：

1、InitCmd -> ERRO 001 Cannot run peer because cannot init crypto, specified path "/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp" does not exist or cannot be accessed: stat /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp: no such file or directory
还未解决。。。。

2、Error: failed to create deliver client for orderer: orderer client failed to connect to orderer.example.com:7050: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp: lookup orderer.example.com on 127.0.0.11:53: no such host"
原因：
（1）之前搭建的网络没有清除干净，退出cli容器：exit；清除网络：./byfn.sh -m down；重新启动网络进入cli容器
（2）调出orderer节点的容器日志：docker logs orderer.example.com

可以看出是kafka版本的设置问题（Kafka.Version unset, setting to 0.10.2.0），至于kafka版本，如果不设置的默认的就是0.10.2.0.为什么会出现这种情况，我也不是很清楚，大佬路过还请指教一二。。。。
解决方法就是去更改kafka的版本。kafka版本控制的文件是/fabric-samples/config/orderer.yaml
