Fabric e2e_cli: Ordering Service is not available, Please try again …

1，安装基础环境与部署Fabric系统步骤

1. 安装Docker CE
2. 安装Docker-Compose
3. 安装与配置go语言环境
4. 下载Fabric源码并编译
5. 下载Fabric相关Docker镜像

2， 运行e2e_cli示例

• 运行e2e_cli步骤：
  a.基础环境安装并运行e2e_cli环境时，切换到示例目录中，如下所示。
  cd /opt/gopath/src/github.com/hyperledger/fabric/examples/e2e_cli/
  b.运行e2e_cli中的network_setup.sh脚本
  bash network_setup.sh up

运行成功后如图所示。

3， 遇到的问题及解决办法

问题1：在阿里云上部署Fabric，遇到如下问题

================== ERROR !!! FAILED to execute End-2-End Scenario ==================

解决办法一：
修改 /etc/resolv.conf 配置，如下所示。

原因分析参见【 阿里云环境部署Hyperledger Fabric之SIGSEGV 问题分析解解决经验分享 https://yq.aliyun.com/articles/238940 】

解决办法二：
在docker-compose-cli.yml，docker-compose-base.yaml， peer-base.yaml中cli增加

• GODEBUG=netdns=go
  在每个关键字段environment：下面都加入该条配置。
  

问题2：运行启动脚本，出现"network e2ecli_default not found"错误提示

2020-05-06 08:38:39.417 UTC [msp/identity] Sign -> DEBU 006 Sign: plaintext: 0ABF070A6708031A0C088FEFC9F50510...535010030A04657363630A0476736363

Error: Error endorsing chaincode: rpc error: code = Unknown desc = error starting container: API error (404): {"message":"network e2ecli_default not found"}

解决办法：目录切换到e2e_cli目录，运行下列命令
vim ./base/peer-base.yaml
修改peer-base.yaml中的
-CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=e2ecli_default 为
-CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=e2e_cli_default
