數據卷
數據卷就是在宿主中可以在容器之間進行共享和重用的一系列和文件和文件夾，通過docker run -v命令可以將數據卷掛載到對應的容器目錄空間，進行文件讀取，容器卷特性如下
-
數據卷可以在容器之間共享和重用，容器間傳遞數據將變得高效方便
-
對數據卷內數據的修改會立馬生效，無論是容器內操作還是本地操作
-
對數據卷的更新不會影響鏡像，解耦了應用和數據
-
卷會一直存在，直到沒有容器使用，可以安全地卸載它
數據卷用-v添加 以tomcat爲例
以下爲當前主機目錄和當前正在運行容器列表，可以看到沒有任何的容器正在運行

以-v啓動tomcat
格式：docker run -v [本機絕對路徑]:[容器中的路徑] [鏡像名[:TAG]或ID]
使用命令：docker run -it -p 8080:8080 -v /tomcatFile/www:/usr/local/tomcat/webapps/www c81106060722
將主機上的/tomcatFile/www目錄與容器中的/usr/local/tomcat/webapps/www綁定，此時綁定的路徑是tomcat中的webapps

在主機的/tomcatFile/www/文件夾中新建了一個index.html頁面，並在裏面寫了一段內容
[root@localhost lb]# cd /tomcatFile/www/
[root@localhost www]# touch index.html
[root@localhost www]# vi index.html
[root@localhost www]# cat index.html
<h1>HELLO DOCKER'S TOMCAT</h1>
[root@localhost www]#
如果和容器綁定成功，通過瀏覽器訪問tomcat中的www文件夾，就能顯示這個頁面內容。
綁定成功後，兩個文件夾中的內容保持同步，隨意修改其中任何文件夾中的內容，另一個文件夾都會同步修改，就算容器停止後，重啓以後依舊綁定並同步。
如果想要容器中的文件夾內容爲只讀，可以通過:ro命令來實現。
同樣的命令，加只讀後：
docker run -it -p 8080:8080 -v /tomcatFile/www:/usr/local/tomcat/webapps/www:ro c81106060722
用DockerFile的方式添加數據卷
1. 以centos:7爲例
在主機根目錄下添加一個文件夾，名稱隨意，我的名稱爲myDocker，並在裏面創建Dockerfile文件
[root@localhost /]# mkdir myDocker
[root@localhost /]# cd /myDocker/
[root@localhost myDocker]# touch Dockerfile
[root@localhost myDocker]# ll
總用量 0
-rw-r--r--. 1 root root 0 11月 24 15:47 Dockerfile
在Dockerfile文件中編寫如下內容
FROM centos:7
VOLUME ["/data1","/data2","/data3"]
CMD echo "create success!!!!"
CMD /bin/bash
執行build命令，構建一個新的鏡像
語法：docker build -f [自定義的Dockerfile絕對路徑] -t [鏡像名稱[:TAG]] . (命令末尾有個點，不要忽略)
測試命令：docker build -f /myDocker/Dockerfile -t lgz/centos:build01 .
[root@localhost myDocker]# docker build -f /myDocker/Dockerfile -t lgz/centos:build01 .
Sending build context to Docker daemon 2.048kB

可以看到我的鏡像列表中已經有了一個版本號爲build01的centos鏡像
運行新構建的鏡像，可以看到，容器中已經自帶剛纔定義的三個data數據卷

使用inspect命令，查看數據卷綁定的主機中的文件夾是哪些
[root@localhost myImage]# docker ps

[root@localhost myImage]# docker inspect 7686d359b88b
爲了驗證，在容器中data1數據卷綁定的本機文件夾中新建一個文件
[root@localhost myImage]# cd /var/lib/docker/volumes/13a36b79604c6842f3da5032457a198a64f568122b67fe063a9a68e8fe2e5d7f/_data

[root@localhost _data]# ll

-rw-r--r--. 1 root root 0 11月 24 16:12 firstFile.txt
而在容器中的data1中，文件已經順利同步過來了
[root@7686d359b88b /]# cd data1/
[root@7686d359b88b data1]# ll
total 0
-rw-r--r--. 1 root root 0 Nov 24 08:12 firstFile.txt
2. tomcat爲例
修改Dockerfile文件，或者新建文件一個都可以，內容如下
FROM tomcat:jdk8-openjdk
VOLUME ["/usr/local/tomcat/webapps/www","/usr/local/tomcat/webapps/myDoc"]
CMD echo "create success!!!!"
CMD /usr/local/tomcat/bin/catalina.sh run
最後一段目的是讓運行的時候tomcat自己運行起來
構建新的鏡像
測試命令：docker build -f /myDocker/Dockerfile -t lgz/tomcat:build01 .
[root@localhost myDocker]# docker build -f /myDocker/Dockerfile -t lgz/tomcat:build01 .
Sending build context to Docker daemon 2.048kB
