一、釋出映象到DcokerHub

1. 首先需要去https://hub.docker.com/網站註冊屬於自己的賬號；
2. 確定新註冊的賬號可以登陸；
3. 在我們的伺服器上提交自己製作的映象檔案。

[root@docker ~]# docker login --help

Usage:  docker login [OPTIONS] [SERVER]

Log in to a Docker registry.
If no server is specified, the default is defined by the daemon.

Options:
  -p, --password string   Password
      --password-stdin    Take the password from stdin
  -u, --username string   Username

[root@docker ~]# docker login -u jzyue  
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

[root@docker ~]# docker push jzyue/tomcat01:1.0  #提交自己的映象到dockerhub上
The push refers to repository [docker.io/jzyue/tomcat01]

常見報錯

在提交的時候提示沒有tag標籤
[root@docker ~]# docker  images
REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE
tomcat01              latest              66fd9bfabe82        13 hours ago        695MB

[root@docker ~]# docker push jzyue/diytomcat:1.0
The push refers to repository [docker.io/jzyue/diytomcat]
An image does not exist locally with the tag: jzyue/diytomcat

這裡需要對映象打一個標籤
[root@docker ~]# docker tag 66fd9bfabe82 jzyue/tomcat01:1.0
[root@docker ~]# docker images
REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE
jzyue/tomcat01        1.0                 66fd9bfabe82        13 hours ago        695MB

二、釋出映象到阿里雲映象倉庫

1.登陸到阿里雲(https://account.aliyun.com)；

2.找到容器映象服務；

3.建立名稱空間；

4.建立容器映象倉庫，倉庫型別：公開代表所有人都可以看到；私有隻有自己可以看到；

5.進入到倉庫，根據阿里雲的操作指南來實際操作一下。

[root@docker ~]# sudo docker login --username=jzyue2012@sina.cn registry.cn-beijing.aliyuncs.com #登陸到阿里雲
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
[root@docker ~]# docker images  #檢視映象
REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE
jzyue/tomcat01        1.0                 66fd9bfabe82        14 hours ago        695MB
[root@docker ~]# docker push jzyue/tomcat01:1.0  #推送映象到阿里雲倉庫
The push refers to repository [docker.io/jzyue/tomcat01]
cd2c8c332d4e: Pushed
097d8efb1a01: Pushed
fc617a256ca8: Pushed
4de30c3ac6c2: Pushing [============================================>      ]  340.6MB/384.5MB
