對(duì)于docker各個(gè)平臺(tái)的安裝和docker的好處就不說了斤儿。
了解docker最快的辦法當(dāng)然就是用它了??
docker架構(gòu)組織關(guān)系
先簡(jiǎn)單了解下docker的一個(gè)架構(gòu)
-
docker daemon我們也稱之為docker的守護(hù)進(jìn)程呛哟，叫做docker的server端 -
docker CLI提供給我們一個(gè)統(tǒng)一的操作界面，實(shí)現(xiàn)容器和鏡像的管理凳谦，也叫做docker的client端 - server端和client是通過REST API來進(jìn)行通信的，所以說server端和client是可以分開部署
- 我們不能直接與server進(jìn)行交互媒楼，但是可以通過容器這個(gè)橋梁來進(jìn)行交互
-
Image（鏡像）： 一個(gè)只讀的鏡像模板掀宋。可以自己創(chuàng)建一個(gè)鏡像也可以從網(wǎng)站上下載鏡像供自己使用盔性。鏡像包含了一個(gè)RFS（Root File System） -
Container（容器）：由client通過鏡像創(chuàng)建的實(shí)例霞丧，用戶在容器中運(yùn)行應(yīng)用，每個(gè)應(yīng)用運(yùn)行在隔離的容器中冕香，享有獨(dú)自的權(quán)限蛹尝、用戶、網(wǎng)絡(luò)悉尾。確保不會(huì)相互干擾突那。 -
Data Volumes（數(shù)據(jù)卷）：Volume可以將容器以及容器產(chǎn)生的數(shù)據(jù)分離開來，這樣构眯，當(dāng)你使用docker rm my_container刪除容器時(shí)愕难，不會(huì)影響相關(guān)的數(shù)據(jù)。
docker 相關(guān)命令
- docker version
docker是GO語言開發(fā)的惫霸，所以會(huì)包含GO的版本
