原文鏈接地址：『高級(jí)篇』docker之DockerSwarm調(diào)整微服務(wù)及服務(wù)配置（29）

上次已經(jīng)搭建好了swarm的集群環(huán)境，server01，server02，server03三臺(tái)虛擬機(jī)，每一臺(tái)的manager節(jié)點(diǎn)也是work節(jié)點(diǎn)，首先我們考慮的問(wèn)題是服務(wù)的發(fā)現(xiàn)，從微服務(wù)的角度考慮，我們有得服務(wù)是為了其他服務(wù)使用的，如message service，user service，對(duì)于swarm上，有的需要暴露端口給其他服務(wù)使用，有的是直接通過(guò)服務(wù)的名稱(chēng)就可以訪問(wèn)的，改造模式，改造代碼，然后上傳到鏡像倉(cāng)庫(kù)。最后配置一個(gè)docker stack 把他們的關(guān)系編寫(xiě)出來(lái)，一條命令搞定了。源碼：https://github.com/limingios/msA-docker swarm分支

docker stack 創(chuàng)建，因?yàn)闄C(jī)器內(nèi)存太小，我還是使用的外網(wǎng)，下載鏡像有點(diǎn)慢。

docker stack deploy -c ms-service.yml ms
docker stack services ms 

PS：創(chuàng)建成功，下一步就是調(diào)試微服務(wù)。
