如果在docker-compose文件中設(shè)置external為true嚼隘，那么使用docker-compose up -d來啟動(dòng)服務(wù)時(shí)秉版，首先docker引擎會(huì)查找external聲明的網(wǎng)絡(luò)，找到后進(jìn)行連接涤垫。否則會(huì)提示錯(cuò)誤：
ERROR: Network unifyca declared as external, but could not be found. Please create the network manually using docker network create unifyca and try again.
當(dāng)其值為false時(shí)姑尺，會(huì)自動(dòng)創(chuàng)建一個(gè)unifyca的網(wǎng)絡(luò)，如果沒有networks字段時(shí)蝠猬，會(huì)創(chuàng)建一個(gè)unifyca_default的網(wǎng)絡(luò)切蟋。
