1.背景

類似于電腦,要在朋友的電腦上跑你寫的Java程序,就得檢查他電腦有沒有安裝Java環(huán)境.

類似的,要想在別的電腦上跑你寫的Python程序,又得檢查那臺電腦有沒有裝python.

如何讓自己寫的程序換到別的電腦上后,可以便捷的運行起來?

將程序和程序的環(huán)境打包遷移,是一種解決方案.

• 為啥不用虛擬機(jī)?

虛擬機(jī)安裝太麻煩,就好比一個完整的操作系統(tǒng),啟動起來很費時間.

所以,你可以簡單的理解為:Docker就是一個輕量級的虛擬機(jī)(只虛擬你需要的軟件運行環(huán)境,冗余的一點都不要).

• 網(wǎng)上看到的另一個Docker入門網(wǎng)站,還不錯.

4.Docker主要概念

類比win

鏡像: 程序安裝包

容器: 安裝好的程序

(鏡像的)倉庫: 放安裝包的倉庫.

4.1 倉庫喘沿、鏡像和容器

• 鏡像

  程序安裝包

  Docker鏡像里包含了已打包的應(yīng)用程序及其所依賴的環(huán)境。它包含應(yīng)用程序可用的文件系統(tǒng)和其他元數(shù)據(jù)竭贩，如鏡像運行時的可執(zhí)行文件路徑摹恨。

• 鏡像倉庫

  安裝包的倉庫

  Docker鏡像倉庫用于存放Docker鏡像，以及促進(jìn)不同人和不同電腦之間共享這些鏡像娶视。當(dāng)編譯鏡像時晒哄，要么可以在編譯它的電腦上運行，要么可以先上傳鏡像到一個鏡像倉庫肪获，然后下載到另外一臺電腦上并運行它寝凌。某些倉庫是公開的，允許所有人從中拉取鏡像孝赫，同時也有一些是私有的较木，僅部分人和機(jī)器可接入。

• 容器

  安裝好的軟件

  Docker容器通常是一個Linux容器青柄，它基于Docker鏡像被創(chuàng)建伐债。一個運行中的容器是一個運行在Docker主機(jī)上的進(jìn)程预侯，但它和主機(jī)，以及所有運行在主機(jī)上的其他進(jìn)程都是隔離的峰锁。這個進(jìn)程也是資源受限的萎馅，意味著它只能訪問和使用分配給它的資源（CPU、內(nèi)存等）虹蒋。

4.2 打包糜芳、分發(fā)和部署

• 打包

  制作鏡像

  把你軟件本身、所需要的依賴魄衅、三方庫等制作成一個"安裝包"

• 分發(fā)

  上傳鏡像倉庫

  將安裝包上傳到軟件倉庫,別人可以方便的下載和安裝

• 部署

  啟動鏡像,獲得運行著的容器.win開發(fā)好后.

  拿著下載好的安裝包,用命令行運行起來(安裝包中帶著運行環(huán)境)

4.3 一個簡單的流程

4.2.1 開發(fā)者在開發(fā)環(huán)境(本地機(jī)器)開發(fā)好應(yīng)用后,制作出鏡像峭竣。

Docker執(zhí)行命令，在本地機(jī)器構(gòu)建出鏡像并存儲晃虫。

4.2.2 開發(fā)者執(zhí)行上傳鏡像命令,上傳本地鏡像到鏡像倉庫.

Docker收到命令后皆撩，將本地鏡像上傳到鏡像倉庫。

4.2.3 開發(fā)者向生產(chǎn)環(huán)境(遠(yuǎn)端服務(wù)器)發(fā)送運行鏡像命令.

生產(chǎn)環(huán)境服務(wù)器收到命令后哲银，Docker會從鏡像倉庫拉取鏡像扛吞，然后基于鏡像運行容器。

run參數(shù)

• -rm

  在容器退出時自動清理容器內(nèi)部的文件系統(tǒng)

  在Docker容器退出時,默認(rèn)容器內(nèi)部的文件系統(tǒng)仍然被保留,以方便調(diào)試并保留用戶數(shù)據(jù).

  但是,對于前臺運行的容器,由于其只是在開發(fā)調(diào)試過程中短期運行,其用戶數(shù)據(jù)并無保留的必要.

  啟動時設(shè)置-rm選項蟆融，這樣在容器退出時就能夠自動清理容器內(nèi)部的文件系統(tǒng).

• -i

  保持容器運行

• -p

  端口映射

• -e

  傳遞環(huán)境變量

• -t

  為容器重新分配一個偽輸入終端

• -d

  以守護(hù)進(jìn)程模式運行容器草巡，退出后容器不會停止

• -it

  創(chuàng)建一個交互式容器，推出后容器容器停止運行

• -id

  創(chuàng)建一個守護(hù)容器型酥；退出后容器不停止運行

• –-name

  為創(chuàng)建的容器命名

eg: 拷貝eb67258c80d1中的/home/test.txt到宿主機(jī)的/home文件夾下

docker cp eb67258c80d1:/home/test.txt /home

容器停止了也可以拷貝,只要容器還在,容器里面的文件就也還在.</code-pre>

7.網(wǎng)絡(luò)相關(guān)

容器可以比擬做一個獨立的系統(tǒng)環(huán)境,能配置自己網(wǎng)絡(luò),所以說容器里的localhost不一定等于宿主機(jī)的localhost

網(wǎng)絡(luò)模式

• bridge：橋接docker（默認(rèn)創(chuàng)建時,不指定網(wǎng)絡(luò)驅(qū)動,將使用bridge模式）

• none：不配置網(wǎng)絡(luò)

• host：和宿主機(jī)共享網(wǎng)絡(luò)

  例如:當(dāng)你在容器上使用80端口訪問其他應(yīng)用,使用的是宿主機(jī)的80端口.

• container：容器網(wǎng)絡(luò)連通（用的少郁竟，局限很大）
