docker镜像的导出和导入

搭建Fabric1.4网络，跑通End-2-End案例时，需要对所需要的docker镜像进行拉取，考虑到网络问题，可以将已经有完整环境的虚拟机上的docker镜像进行导出，然后拷贝到现有虚拟机进行导入，具体操作如下：

1.docker镜像的导出（根据镜像的Image ID保存到本虚拟机的/tmp/docker-images文件夹）

docker save 432c24764fbb> /tmp/docker-images/fabric-tools-1.4.1.tar
docker save d7433c4b2a1c> /tmp/docker-images/fabric-ccenv-1.4.1.tar
docker save ec4ca236d3d4> /tmp/docker-images/fabric-orderer-1.4.1.tar
docker save a1e3874f338b> /tmp/docker-images/fabric-peer-1.4.1.tar
docker save 3a1799cda5d7> /tmp/docker-images/fabric-ca-1.4.1.tar
docker save 20c6045930c8> /tmp/docker-images/fabric-zookeeper-0.4.15.tar
docker save b4ab82bbaf2f> /tmp/docker-images/fabric-kafka-0.4.15.tar
docker save 8de128a55539> /tmp/docker-images/fabric-couchdb-0.4.15.tar
docker save 9d6ec11c60ff> /tmp/docker-images/fabric-baseos-0.4.15.tar

2.docker镜像的导入（通过U盘等设备将已经备份好的镜像tar包拷贝到不能联网或网络连接有问题的虚拟机上进行导入，存放目录同为/tmp/docker-images，也可更改目录，看自己习惯）

docker load < /tmp/docker-images/fabric-tools-1.4.1.tar
docker load < /tmp/docker-images/fabric-ccenv-1.4.1.tar
docker load < /tmp/docker-images/fabric-orderer-1.4.1.tar
docker load < /tmp/docker-images/fabric-peer-1.4.1.tar
docker load < /tmp/docker-images/fabric-ca-1.4.1.tar
docker load < /tmp/docker-images/fabric-zookeeper-0.4.15.tar
docker load < /tmp/docker-images/fabric-kafka-0.4.15.tar
docker load < /tmp/docker-images/fabric-couchdb-0.4.15.tar
docker load < /tmp/docker-images/fabric-baseos-0.4.15.tar

3.导入后的镜像的TAG都为空，需要为镜像做TAG

docker tag 432c24764fbb docker.io/hyperledger/fabric-tools:latest
docker tag d7433c4b2a1c docker.io/hyperledger/fabric-ccenv:latest
docker tag ec4ca236d3d4 docker.io/hyperledger/fabric-orderer:latest
docker tag a1e3874f338b docker.io/hyperledger/fabric-peer:latest
docker tag 3a1799cda5d7 docker.io/hyperledger/fabric-ca:latest
docker tag 20c6045930c8 docker.io/hyperledger/fabric-zookeeper:latest
docker tag b4ab82bbaf2f docker.io/hyperledger/fabric-kafka:latest
docker tag 8de128a55539 docker.io/hyperledger/fabric-couchdb:latest
docker tag 9d6ec11c60ff docker.io/hyperledger/fabric-baseos:latest
