docker commit 提交本地修改的打镜像,只是为了演示，实际生产中不建议这种操作行为

  1. docker commit -m "说明" -a "修改人,提交人" <容器id>  目标镜像仓库/镜像名:版本号

-m:提交的描述信息
-a:指定镜像作者
0d736655a300：容器ID
baxiang/contos7:1.0.0:指定要创建的目标镜像名

docker tag

使用阿里云的镜像

  1. sudo docker tag [ImageId] registry.cn-beijing.aliyuncs.com/baxiang/centos7:[镜像版本号]

docker push

  1. docker image tag [imageName] [username]/[repository]:[tag]
  1. sudo docker push registry.cn-beijing.aliyuncs.com/baxiang/centos7:[镜像版本号]
