写在前面：以下内容是基于 阿里云服务器 | 系统centos7.6 为基础展开的！

目录

1. 官方Push镜像

2.阿里云 push 镜像

3.解决错误不是一蹴而就

---

1. 官方Push镜像

        1.首先登录自己DockerHub账号

[root@liustudy tomcat]# docker login -u liusirstudy
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

        2. 将要 push 的镜像名设置 tag

docker tag 【镜像名】用户名/自定义名称：【tag】

eg: docker  tag [镜像名] liusirstudy/tomcat:1.0

        3. 发布镜像 docker push liusirstudy/tomcat:1.0

==》push成功！

2.阿里云 push 镜像

        1.首先登录阿里云账号

[root@liustudy /]# docker login --username=羽鑫墨鑫轩 registry.cn-hangzhou.aliyuncs.com
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

        2.将要 push 的镜像名设置 tag

[root@liustudy /]# docker tag feb5d9fea6a5 registry.cn-hangzhou.aliyuncs.com/liustudy/study_test:1.0

命令组成：

docker tag 【镜像名】registry.cn-hangzhou.aliyuncs.com/命名空间/仓库名:【tag】

举例：push docker 的hello-world 到服务器

        3.push 镜像到服务器

docker push registry.cn-hangzhou.aliyuncs.com/liustudy/study_test:1.0

         4.查看效果

 

 3.解决错误不是一蹴而就

        在push 镜像到阿里服务器的过程中尝试了很多方法：

1.登录阿里云服务器后，不设置 registry.cn-hangzhou.aliyuncs.com

我以为登录后默认在这个里面了 ，结果不是，还是需要加上这个；

[root@liustudy /]# docker tag feb5d9fea6a5 liustudy/study_test:1.0
[root@liustudy /]# docker push liustudy/study_test:1.0
The push refers to repository [docker.io/liustudy/study_test]
e07ee1baac5f: Preparing
denied: requested access to the resource is denied

2.自定义名也不可以，阿里必须走 /命名空间/仓库，这里区别官方的，官方的是 用户名/自己命名：版本！

[root@liustudy /]# docker tag feb5d9fea6a5 liusir/hello:1.0
[root@liustudy /]# docker push liusir/hello:1.0
The push refers to repository [docker.io/liusir/hello]
e07ee1baac5f: Preparing 
denied: requested access to the resource is denied
