#### Docker 如何提交一个自己的镜像 ####

commit 镜像

docker commit 提交容器成为一个新的副本
    
    # 命令和git原理类似
    docker commit -m="提交的描述信息" -a="作者" 容器id 目标镜像名:[tag]

本地测试

# 1、启动一默认的tomcat
    [root@liulihui /]# docker images
    REPOSITORY            TAG       IMAGE ID       CREATED         SIZE
    tomcat                latest    fb5657adc892   11 months ago   680MB
    # 交互默认启动
    
    [root@liulihui /]# docker run -it -p 8080:8080 tomcat
    # 2、进入容器发现这个默认的tomcat 是没有webapps应用，镜像的原因，官方的镜像默认webapps 下面没有文件的
    
    [root@liulihui /]# docker ps -a
    CONTAINER ID   IMAGE                 COMMAND                  CREATED             STATUS                           PORTS                                       NAMES
    8a5d2b1df7a1   tomcat                "catalina.sh run"        4 minutes ago       Up 4 minutes                     0.0.0.0:8080->8080/tcp, :::8080->8080/tcp   serene_goldwasser
    
    # 进入容器
    [root@liulihui /]# docker exec -it 8a5d2b1df7a1 /bin/bash
    root@8a5d2b1df7a1:/usr/local/tomcat# ls
    BUILDING.txt  CONTRIBUTING.md  LICENSE	NOTICE	README.md  RELEASE-NOTES  RUNNING.txt  bin  conf  lib  logs  native-jni-lib  temp  webapps  webapps.dist  work
    root@8a5d2b1df7a1:/usr/local/tomcat# cd webapps
    # 查看基本文件
    root@8a5d2b1df7a1:/usr/local/tomcat/webapps# ls
    root@8a5d2b1df7a1:/usr/local/tomcat/webapps# 
    # 3、自己拷贝基本的文件
    
    root@8a5d2b1df7a1:/usr/local/tomcat/webapps# cd ..
    
    # 拷贝基本文件
    root@8a5d2b1df7a1:/usr/local/tomcat# cp -r webapps.dist/* webapps
    root@8a5d2b1df7a1:/usr/local/tomcat# cd webapps
    # 查看文件
    root@8a5d2b1df7a1:/usr/local/tomcat/webapps# ls
    ROOT  docs  examples  host-manager  manager
    root@8a5d2b1df7a1:/usr/local/tomcat/webapps# 
    
    # 4、将我们拷贝过的容器通过commit提交为一个镜像，以后就使用我们修改过的镜像即可，这就是我们自己的一个修改的镜像
    
    [root@liulihui /]# docker ps -a
    CONTAINER ID   IMAGE                 COMMAND                  CREATED             STATUS                           PORTS                                       NAMES
