docker - 在Fabric第一网络示例中，热修复错误: “transport: error while dialing: dial tcp: lookup peer0.org1.example.com: no such host”

Question

无法运行结构第一个网络示例

这是我运行时的日志:./byfn up

Error: error getting endorser client for channel: endorser client failed to connect to peer0.org1.example.com:7051: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp: lookup peer0.org1.example.com: no such host"
peer0.org1 failed to join the channel, Retry after 9 seconds

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

同行应该能够加入该 channel

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

这是一个众所周知的问题
简而言之，这是由于文件resolv.conf的更改引起的，Hyperledger Fabric中的容器间域名解析已从纯Go解析器切换到cgo解析器，由已知静态链接cgo引起的SIGSEGV错误被触发，因此Hyperledger Fabric部署失败。
