fabirc1.2 e2e_cli遇到的问题

昨天遇到了一个很奇怪的问题，新拉下来的Fabric代码，指定1.2版本后，启动e2e_cli demo，突然orderer不可用了！
并且在本机mac上做了测试，可用；最近的两台云主机都尚未运行过fabric,应该不是什么文件残留的问题；并且重装云服务器系统后，也还是改问题。

  • 具体报错如下,单独运行orderer容器，得到输出日志，看到是证书验证失败

!!!!!!!!!!!!!!! Ordering Service is not available, Please try again ... !!!!!!!!!!!!!!!!
================== ERROR !!! FAILED to execute End-2-End Scenario ==================

查找资料，发现有人遇到过是版本的问题；突然想到，我的mac之前是有残留镜像的，并且fabric使用的都是latest标签的镜像，这就把镜像版本问题掩藏了，好像看起来都没问题，尝试更换镜像，结果ok!

  • 更换fabric docker镜像
    如下命令会下载fabric-example,并拉取1.2.0的相关镜像;
    如果因为墙的问题，curl获取不到该脚本，可通过配置代理，或者复制文末脚本（chmod +x test.sh && ./test.sh 1.2.0）
curl -sSL http://bit.ly/2ysbOFE | bash -s 1.2.0
  • 再次启动e2e_cli
