启动docker
service docker start
启动docker实例
docker start 容器ID或容器名
1. 先查看已经暂停的容器实例信息
2. 通过docker start 59ec 启动容器
3. 通过docker ps 查看当前启动的容器
需要升级docker中的go版本
wget https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz
sudo rm -rf /opt/go
sudo tar -C /opt -xzvf go1.10.3.linux-amd64.tar.gz
export $GOPATH=/opt/gopath
export $GOROOT=/usr/local/go
byfn.sh -m up
byfn.sh -m restart
(之后)
进? docker 容器
docker exec -it cli bash
（之前必须docker-compose-cli.yaml中的cli command行改sleep
tail -f /dev/null
）
./scripts/script.sh mychannel
（开始）
往docker中传文件：
docker inspect -f '{ {.Id}}' cli

以下启动REST API的web服务
在 GOPATH 的 root 目录中创建 docker-compose.yml 文件。粘贴以下内容：

部署示例
Hyperledger Fabric 提供了一个用于与该结构交互的 REST Web 服务接口。与 fabric 的第一次交互是部署链代码。确保本地区块链网络正在运行，然后启动 SoapUI，单击 REST 按钮创建一个新的 REST 项目。您会看到一个类似图 3 的对话框，在其中输入用于所有 REST 请求的基础 URL：
图 3. SoapUI New REST Project 对话框
输入 http://localhost:7050 作为 URL，然后单击 OK。端口 7050 是 fabric 使用的默认 REST 端口，而且因为区块链网络是在本地计算机上运行的，所以将使用 localhost 作为主机名。
在 SoapUI 启动后，可以执行一次快速冒烟测试，以确保它能与本地区块链网络进行通信。展开刚创建的新的 REST 资源，直到看到 Request 1，然后在 Editor 窗口中打开它。使用 GET 方法，在 resource 下输入 /chain。确保单击了 output 选项卡上的 JSON 选项，然后运行请求（通过单击 arrow 图标）。执行此请求时，会在 Editor 窗口右侧的输出选项卡中返回当前区块的哈希值，如图 4 所示
2、关闭原有例子
3、第一终端进入chaincode-docker-devmode，启动网络
docker-compose -f docker-compose-simple.yaml up
4、第二终端进入docker
docker exec -it chaincode bash
5、第二终端进入chaincode文件夹
/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode
6、第二个终端启动chaincode
CORE_PEER_ADDRESS=peer:7051 CORE_CHAINCODE_ID_NAME=mycc:0 ./chaincode002
7、第三个终端
docker exec -it cli bash
安装链码
peer chaincode install -p chaincodedev/chaincode/chaincode002 -n mycc -v 0
实例化链码
peer chaincode instantiate -n mycc -v 0 -c '{"Args":["str","helloworld"]}' -C myc
# 查询链码
$ peer chaincode query -n mycc -c '{"Args":["get","str"]}' -C myc
# 调用链码
peer chaincode invoke -n mycc -c '{"Args":["set", "str", "helloworld111"]}'
-C myc
# 查询链码
$ peer chaincode query -n mycc -c '{"Args":["get","str"]}' -C myc
docker rm -f $(docker ps -aq)
