351-fabric浅析docker-compose

fabric浅析docker-compose






我们要启动peer,orderer和客户端
先要配置docker-compose

那么我们先来看下官方的docker-compose
我们打开/fabric-samples/first-network

然后看下目录
abc@abc:~/workspace/fabric/sample/fabric-samples/first-network$ ls
base                     docker-compose-couch-org3.yaml    eyfn.sh
byfn.sh                  docker-compose-couch.yaml         org3-artifacts
channel-artifacts        docker-compose-e2e-template.yaml  README.md
configtx.yaml            docker-compose-etcdraft2.yaml     scripts
crypto-config.yaml       docker-compose-kafka.yaml
docker-compose-cli.yaml  docker-compose-org3.yaml




我们找到docker-compose-cli.yaml
我们把docker-compose-cli.yaml复制一下






然后我们来看一下
docker-compose-cli.yaml

我们发现有用到base文件夹
那么我们去first-network文件夹把base文件夹也拷贝过来

abc@abc:~/workspace/fabric$ ls
abc.yaml  channel.tx     crypto-config            genesis.block  template.yaml
base      configtx.yaml  docker-compose-cli.yaml  sample









我们来看一下docker-compose里面的cli

看下里面有什么
1.container_name 	容器名字
2.image				镜像
3.tty				true,有终端绑定
4.stdin_open		true,标准输入为打开状态
5.environment		环境变量
6.working_dir		工作目录
7.command			执行bash命令
8.volumes			数据卷挂载
9.depends_on		
10.networks			












我们来看下镜像
docker images

我们来看一下环境变量

leader节点
1.peer节点
2.代表组织和orderer节点通信
3.在一个组织中,leader节点只有一个
4.谁都有资格做leader节点
5.如何指定
	1.手动指定,如果指定leader挂了,就没有leader节点了
	2.自动选举,当前的leader节点挂了,还是会再选一个

- CORE_PEER_GOSSIP_USELEADERELECTION=true 	#是否自动选举
- CORE_PEER_GOSSIP_ORGLEADER=false			#是否指定当前节点为leader
