  19. Login Succeeded
  20. [root@--- ~]#

2、服务器上提交镜像

docker push [OPTIONS] NAME[:TAG]
docker push命令推送镜像的规范是：注册用户名/镜像名。

  1. 使用以下方法之一命名您的本地镜像：
  3. 当你构建它们时，使用 docker build -t <hub-user>/<repo-name>[:<tag>]
  4. 重命名现有的本地镜像 docker tag <existing-image> <hub-user>/<repo-name>[:<tag>]
  5. 通过docker commit <existing-container> <hub-user>/<repo-name>[:<tag>] 用于提交更改
  7. docker push <hub-user>/<repo-name>:<tag>
  1. docker push xiao/tomcat
  2. Using default tag: latest
  3. The push refers to repository [docker.io/xiao/tomcat]
  4. 69421fc728fb: Preparing 
  5. 1f6217f0c2bb: Preparing

  9. denied: requested access to the resource is denied # 拒绝
  11. #推送失败的原因: name必须是注册用户名
  12. #解决push失败问题
  13. #增加一个tag, 重命名镜像
  14. docker tag 24b3a476f143 xiaobluewhale/tomcat:1.0
  15. The push refers to repository [docker.io/xiaobluewhale/tomcat]
  17. docker images
  18. REPOSITORY            TAG       IMAGE ID       CREATED        SIZE

  23. #推送镜像
  24. docker push xiaobluewhale/tomcat:1.0

提交的时候也是按照镜像的层级提交的
在个人DockerHub上查看推送成功的镜像
