1 用docker compose部署服務(wù)

- 需求：假如現(xiàn)在我們手里有很多容器，每個(gè)容器對(duì)應(yīng)每個(gè)服務(wù)，有nginx容器，redis容器，mysql容器等?，F(xiàn)在我們需要批量化的去管理，批量啟動(dòng)，停止，重啟等操作！當(dāng)然你會(huì)說(shuō)用shell，可是如何不用shell來(lái)完成需求呢，那就需要用到接下來(lái)介紹的docker compose了。

- docker compose可以方便我們快捷高效地管理容器的啟動(dòng)、停止、重啟等操作，它類(lèi)似于linux下的shell腳本，基于yaml語(yǔ)法，在該文件里我們可以描述應(yīng)用的架構(gòu)，比如用什么鏡像、數(shù)據(jù)卷、網(wǎng)絡(luò)模式、監(jiān)聽(tīng)端口等信息。我們可以在一個(gè)compose文件中定義一個(gè)多容器的應(yīng)用（比如jumpserver），然后通過(guò)該compose來(lái)啟動(dòng)這個(gè)應(yīng)用。

- 安裝compose
