1.docker-compose网络服务配置文件

 Fabric使用了容器技术,所以需要一个简化的方式来集中化管理这些容器节点。我们使用docker-compose工具来实现一步到位的节点容器管理,而且只需要编写相应的docker-compose-cli.yaml配置文件即可。

可以从以上代码看出该配置文件指定了共计4个容器:一个Orderer,属于两个Org的两个Peer,1个Cli。 

2.fabric相关docker镜像

都在hyperleger路径下:

fabric-peer: peer节点镜像

fabric-orderer: orderer节点镜像

fabric-tools: 工具镜像,cryptogen等工具都在这里面

fabric-ca: ca模块镜像,可以用来生成账号

fabric-ccenv: go语言链码运行环境镜像

fabric-kafka: kafka镜像

fabric-zookeeper: zookeeper镜像

fabric-couchdb: couchdb数据库镜像
