docker - 在fabric first-network示例中，热修复错误：“传输：拨号时出错：拨号tcp：lookup peer0.org1.example.com：没有这样的主机”

问题描述

无法运行结构优先网络示例

这是我运行时的日志：./byfn up

我的环境：

Ubuntu 18.04
Docker version 18.06.1-ce, build e68fc7a
docker-compose version 1.24.0, build 0aa59064
go version go1.11.11 linux/amd64

echo $GOPATH results in /usr/local/go/bin

对等点应该能够加入频道

解决方案

尝试在peer-base.yaml- GODEBUG=netdns=go文件的 environment 部分添加，它可以在fabric-samples/first-newtork/base/中找到

这是一个众所周知的问题，简而言之，这是由于文件 resolv.conf 的更改导致的，Hyperledger Fabric 中的容器间域名解析从纯 Go 解析器切换到 cgo 解析器，由已知静态链接引起的 SIGSEGV 错误cgo 被触发，因此 Hyperledger Fabric 的部署失败。要了解更多信息，请点击此链接。
