注意：代码路径已更新，可以直接参考 https://github.com/yeasy/docker-compose-files/tree/master/hyperledger_fabric/。
Hyperledger Fabric 1.0 版本整体 重新设计了架构，预计将于今年 3 月份发布。目前已经进入了 alpha 阶段，可以进行功能性验证。
本文将介绍如何快速启动一个 Fabric 1.0 的网络，并部署和调用 chaincode 进行测试。
安装 Docker
Docker 支持 Linux 常见的发行版，如 Redhat/Centos/Ubuntu 等，推荐使用 1.12 或者更新的版本。
$ curl -fsSL https://get.docker.com/ | sh
以 Ubuntu 14.04 为例，安装成功后，修改 Docker 服务配置（/etc/default/docker 文件）。
DOCKER_OPTS="$DOCKER_OPTS -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --api-cors-header='*'"
重启 Docker 服务。
$ sudo service docker restart
Ubuntu 16.04 中默认采用了 systemd 管理启动服务，Docker 配置文件在/etc/systemd/system/docker.service.d/override.conf。
修改后，需要通过如下命令重启 Docker 服务。
$ sudo systemctl daemon-reload
$ sudo systemctl restart docker.service
安装 docker-compose
首先，安装 python-pip 软件包。
$ sudo aptitude install python-pip
安装 docker-compose（推荐为 1.8.0 及以上版本）。
$ sudo pip install docker-compose>=1.8.0
获取 Docker 镜像
Docker 镜像可以自行从源码编译，或从社区 DockerHub 仓库下载。这里也提供了调整（精简指令，基于 golang:1.7 基础镜像制作）后的镜像，与社区版本略有差异，但功能是一致的。
通过如下命令拉去相关镜像，并更新镜像别名。
$ docker pull yeasy/hyperledger-fabric-base:latest \
&& docker pull yeasy/hyperledger-fabric-peer:latest \
&& docker pull yeasy/hyperledger-fabric-orderer:latest \
&& docker pull yeasy/hyperledger-fabric-ca:latest \
&& docker pull yeasy/blockchain-explorer:latest \
&& docker tag yeasy/hyperledger-fabric-peer hyperledger/fabric-peer \
&& docker tag yeasy/hyperledger-fabric-orderer hyperledger/fabric-orderer \
&& docker tag yeasy/hyperledger-fabric-ca hyperledger/fabric-ca \
&& docker tag yeasy/hyperledger-fabric-base hyperledger/fabric-baseimage \
&& docker tag yeasy/hyperledger-fabric-base hyperledger/fabric-ccenv:x86_64-1.0.0-snapshot-preview
启动 fabric 1.0 网络
下载 Compose 模板文件。
$ git clone https://github.com/yeasy/docker-compose-files
进入 hyperledger/1.0 目录，查看包括若干模板文件，功能如下。
peers.yml: 包含 peer 节点的服务模板。docker-compose.yml: 启动 1 个 最小化的环境，包括 1 个 peer 节点、1 个 Orderer 节点、1 个 CA 节点。
通过如下命令快速启动。
$ docker-compose up
注意输出日志中无错误信息。
此时，系统中包括三个容器。
$ docker ps

测试 chaincode 操作
启动 fabric 网络后，可以进行 chaincode 操作，验证网络启动正常。
部署 chaincode
通过如下命令进入容器 peer0。
$ docker exec -it fabric-peer0 bash
在容器中执行部署命令，注意输出日志无错误提示，最终返回结果应该为 response:<status:200 message:"OK" payload:"100" >。

此时，系统中生成类似 dev-peer0-test_cc-0-305216ca522e84d0bf8c2b542b16bd3901dcb1879a970ae7c1eee3a74fbdee583eb8b74ad88edefc3d9647d47663f6b14574734c93a36b3968b077f3870d79cf 的 chaincode Docker 镜像，但并没有启动新的容器。
查询 chaincode
对部署成功的 chaincode 执行查询操作，查询 a 的余额。
同样的，在 peer0 容器中执行如下命令，注意输出无错误信息，最后的结果为 <status:200 message:"OK" payload:"100" >。
