docker-compose 中的volumes
docker-compose中有两种方式可以设置volumes，并且都是可持久化的。
1.使用具体路径直接挂载到本地，特点就是直观。
volumes:
- /var/run/:/host/var/run/
- ../chaincode/:/opt/gopath/src/github.com/chaincode
- ./crypto-config:/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/
- ./scripts:/opt/gopath/src/github.com/hyperledger/fabric/peer/scripts/
- ./channel-artifacts:/opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts
2.使用卷标的形式，特点就是简洁，但是不知道数据到底在本地的什么位置。需要通过卷标查看。
volumes:
orderer.example.com:
peer0.org1.example.com:
peer1.org1.example.com:
peer0.org2.example.com:
peer1.org2.example.com:
networks:
byfn:
以上均取自fabric-samples中的first-network中的docker-compose-cli.yaml,在执行byfn.sh up的时候会创建数据卷：
Creating network "net_byfn" with the default driver
Creating volume "net_peer0.org2.example.com" with default driver
Creating volume "net_peer1.org2.example.com" with default driver
Creating volume "net_peer1.org1.example.com" with default driver
Creating volume "net_peer0.org1.example.com" with default driver
Creating volume "net_orderer.example.com" with default driver
查看所有卷标：
wang@wang:~$ docker volume ls
DRIVER VOLUME NAME
local net_orderer.example.com
local net_peer0.org1.example.com
local net_peer0.org2.example.com
local net_peer1.org1.example.com
local net_peer1.org2.example.com
再查看卷对应的地址：
wang@wang:~$ docker volume inspect net_orderer.example.com

}
]
