將容器中的連接埠暴漏給宿主主機。
ports: - "3000" - "80:80" - "22:22" - "127.0.0.1:8000:8000"
預設 "連接埠:連接埠" 將監聽 127.0.0.1 主機。如果需要將連接埠暴漏出去，格式是"IP:PORT:PORT"，IP地址是宿主主機的網絡適配器IP地址。
往/etc/hosts檔案中添加主機名，與Docker client的--add-host類似：
extra_hosts: - "orderer.example.com:10.130.116.8" - "peer0.org1.example.com:10.130.116.9" - "peer1.org1.example.com:10.130.116.10" - "peer0.org2.example.com:10.130.116.25" - "peer1.org2.example.com:10.130.116.27"
