HyperLedger Fabric 1.0的Alpha版本已经于2017年3月中旬正式发布,其官方Docker镜像版本也已经发出。具体地址为[1]。
这样,我们就可以通过拉取镜像的方式,从官网直接拉取镜像进行部署。
我们可能用到的镜像包括:
- hyperledger/fabric-orderer:x86_64-1.0.0-alpha
- hyperledger/fabric-peer:x86_64-1.0.0-alpha
- hyperledger/fabric-javaenv:x86_64-1.0.0-alpha
- hyperledger/fabric-ccenv:x86_64-1.0.0-alpha
- hyperledger/fabric-couchdb:x86_64-1.0.0-alpha
- hyperledger/fabric-zookeeper:x86_64-1.0.0-alpha
- hyperledger/fabric-kafka:x86_64-1.0.0-alpha
- hyperledger/fabric-ca:x86_64-1.0.0-alpha
1. 镜像拉取#
对于每一个镜像,我们可以通过执行下面的指令进行拉取。
docker pull <image name>
像这种一下拉取很多镜像的情况,我们也可以写成一个脚本fabric-pull.sh
:
docker pull hyperledger/fabric-orderer:x86_64-1.0.0-alpha
docker pull hyperledger/fabric-peer:x86_64-1.0.0-alpha
docker pull hyperledger/fabric-javaenv:x86_64-1.0.0-alpha
docker pull hyperledger/fabric-ccenv:x86_64-1.0.0-alpha
docker pull hyperledger/fabric-couchdb:x86_64-1.0.0-alpha
docker pull hyperledger/fabric-zookeeper:x86_64-1.0.0-alpha
docker pull hyperledger/fabric-kafka:x86_64-1.0.0-alpha
docker pull hyperledger/fabric-ca:x86_64-1.0.0-alpha
由于网络不稳定的原因,可能在某个镜像拉取过程中会出现连接失败的情况。多执行几次脚本,问题可能就会解决。
拉取完成后,可以通过docker images
命令查看拉取结果:
可以看到所有的镜像TAG都是x86_64-1.0.0-alpha,至此,镜像拉取成功。
2. 编写Docker-Compose文件#
接下来,我们利用docker-compose来部署网络。这里我参照了杨博士的最小网络启动docker-compose文件[2]。
并相应针对当前版本修改了其中的一些内容,主要是将ca的启动部分做了一下修改,参考官方ca说明文档中的docker启动方法[3]。
docker-compose.yaml
# This compose file will start a Hyperledger Fabric 1.0 MVE, including
# * ca
# * orderer
# * peer
# * sdk for testing
version: '2.0'
services:
ca:
image: hyperledger/fabric-ca:x86_64-1.0.0-alpha
container_name: fabric-ca-server
ports:
- "7054:7054"
environment:
- FABRIC_CA_HOME=/etc/hyperledger/fabric-ca-server
volumes:
- "./fabric-ca-server:/etc/hyperledger/fabric-ca-server"
command: sh -c 'fabric-ca-server start -b admin:adminpw'
orderer:
image: hyperledger/fabric-orderer:x86_64-1.0.0-alpha
container_name: fabric-orderer
hostname: orderer
environment:
- ORDERER_GENERAL_LEDGERTYPE=ram
- ORDERER_GENERAL_BATCHTIMEOUT=10s
- ORDERER_GENERAL_MAXMESSAGECOUNT=10
- ORDERER_GENERAL_MAXWINDOWSIZE=1000
- ORDERER_GENERAL_LISTENADDRESS=0.0.0.0
- ORDERER_GENERAL_LISTENPORT=7050
- ORDERER_RAMLEDGER_HISTORY_SIZE=100
- CONFIGTX_ORDERER_ORDERERTYPE=solo
ports:
- "7050:7050"
command: orderer
peer0:
extends:
file: peer.yml
service: peer
container_name: fabric-peer0
hostname: peer0
environment:
- CORE_PEER_ID=peer0
- CORE_PEER_COMMITTER_LEDGER_ORDERER=orderer:7050
links:
- ca
- orderer
ports:
- 7051:7051
depends_on:
- ca
- orderer
peer.yaml
# Depends on the hyperledger/fabric-peer image.
version: '2'
services:
peer:

environment:

volumes: # docker.sock is mapped as the default CORE_VM_ENDPOINT
- /var/run/docker.sock:/var/run/docker.sock
#volumes:
# - /var/run/:/host/var/run/
command: peer node start
3. 执行部署#
最后,我们将这两个yaml文件放在一起,执行:
docker-compose up
当然,也可以在后台启动,不在前端显示log:
docker-compose up -d
然后通过docker ps
查看容器启动状态:
至此,HyperLedger Fabric 1.0 Alpha版单节点部署成功。
