参考文章1：http://www.blockchainbrother.com/question/343

解决办法：编辑fabric-samples/basic-network/docker-compose.yml

在所有services的environment中添加一行“ - GODEBUG=netdns=go” 即可，问题解决。

例如：

environment:

      - GODEBUG=netdns=go

      - FABRIC_CA_HOME=/etc/hyperledger/fabric-ca-server

      - FABRIC_CA_SERVER_CA_NAME=ca.example.com

      - FABRIC_CA_SERVER_CA_CERTFILE=/etc/hyperledger/fabric-ca-server-config/ca.org1.example.com-cert.pem

      - FABRIC_CA_SERVER_CA_KEYFILE=/etc/hyperledger/fabric-ca-server-config/4239aa0dcd76daeeb8ba0cda701851d14504d31aad1b2ddddbac6a57365e497c_sk
