第五章本地镜像发布到阿里云

1、本地镜像发布到阿里云流程

2、镜像的生成方法

上一讲已经介绍过基于当前容器创建一个新的镜像，新功能增强 docker commit [OPTIONS] 容器ID [REPOSITORY[:TAG]]

OPTIONS说明： -a :提交的镜像作者； -m :提交时的说明文字；

后面的DockerFile章节，第2种方法

3、将本地镜像推送到阿里云

1、本地镜像素材原型就是上次的test/myubuntu

[root@localhost ~]# docker images
REPOSITORY      TAG          IMAGE ID       CREATED         SIZE
test/myubuntu   1.3          8d4088598f0b   7 minutes ago   176MB

2、地址：

3、创建仓库镜像

3.1、选择控制台，进入容器镜像服务 3.2、选择个人实例 3.3、命名空间 3.3.1、继续 3.4、仓库名称 3.4.1、继续 3.5、进入管理界面获得脚本

4、将镜像推送到阿里云

将镜像推送到阿里云registry 管理界面脚本

脚本实例

$ docker login --username=用户名 registry.cn-hangzhou.aliyuncs.com
$ docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/testshanghai/myubuntu:[镜像版本号]
$ docker push registry.cn-hangzhou.aliyuncs.com/testshanghai/myubuntu:[镜像版本号]

4、将阿里云上的镜像下载到本地

为了验证我们先把我们本地的test/myubuntu 删除

[root@localhost ~]# docker images
REPOSITORY                                                TAG          IMAGE ID       CREATED             SIZE
