一、docker 基于容器创建本地web容器化镜像
1、启动指定buysbox 镜像
docker run --name b1 -it busybox:latest
2、创建目录，并创建html
mkdir -p /data/html
vi index.html内容自定义例如：<h1>welcome to busybox<h1>
3、新增窗口，创建镜像
docker commit -a "user<6666@qq.com>" -c 'CMD ["/bin/httpd","-f","-h","/data/html/"]' -p b1 rep/user:v3.0命令解析：
[root@localhost ~]# docker commit --helpUsage: docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]Create a new image from a container's changesOptions:-a, --author string Author (e.g., "John Hannibal Smith <hannibal@a-team.com>")-c, --change list Apply Dockerfile instruction to the created image-m, --message string Commit message-p, --pause Pause container during commit (default true)-a 是设置作者的名字和邮箱
-c 是指定 dockerfile 的配置。例如上面是执行CMD里面的命令。让他启动容器时候就运行
/bin/httpd -f -h /data/html/ ，这样，启动容器化后就可以访问到html index.html 页面
-p 是新建容器，暂定容器
b1 是启动的容器化的命名
查看镜像
[root@localhost ~]# docker image ls

]4、启动镜像
[root@localhost ~]# docker run --name t6 rep/user:v3.05、查看启动容器ip

]6、curl 容器ip地址，可以看到配置生效
[root@localhost ~]# curl 172.17.0.2
<h1>welcome to busybox<h1>二、给容器打标签
[root@localhost ~]# docker tag --helpUsage: docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE1、用法 docker tag 源标签 新标签
如果没有标签，源标签用IMAGE ID如下图
2、通过image_id命令来打标签
docker tag 160a180ce384 rep/user1:v4.0
3. 通过标签，替换标签命令如下
docker tag rep/user1:v4.0 rep/user2:v5.0
