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 --help

Usage:  docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]

Create a new image from a container's changes

Options:
  -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

                    "GlobalIPv6PrefixLen": 0,
                    "MacAddress": "02:42:ac:11:00:02",
                    "DriverOpts": null
                }
            }
        }
    }
]

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 --help

Usage:  docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]

Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE

1、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
