Docker 镜像发布（Dockerhub和阿里云）

一、Dockerhub镜像发布

1.首先在服务器上登录到Docker hub

[root@yang docker]# docker login -u xxx     # xxx为dockerhub的账号
Password: 　　　　# 输入dockerhub账号的密码
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 Succeede

以上显示Login Succeede，说明登录成功！

2.修改新增镜像的命名及标签

语法格式：

docker  tag 源镜像ID  DockerHub账号/修改后的镜像命名:tagname

现有镜像：

[root@yang docker]# docker images
REPOSITORY          TAG                   IMAGE ID            CREATED             SIZE
nginx               latest                f6d0b4767a6c        2 weeks ago         133MB

新增镜像：

[root@yang docker]# docker tag f6d0b4767a6c xiguajun/nginx3:2.0

[root@yang docker]# docker images
REPOSITORY          TAG                   IMAGE ID            CREATED             SIZE
nginx               latest                f6d0b4767a6c        2 weeks ago         133MB
xiguajun/nginx3     2.0                   f6d0b4767a6c        2 weeks ago         133M

解释：

f6d0b4767a6c         # 要修改的镜像ID
xiguajun/nginx3      # 新增的镜像命名
2.0                  # 自定义tag标签

3.上传（push）镜像到Docker Hub

[root@yang docker]# docker push xiguajun/nginx3:2.0
The push refers to repository [docker.io/xiguajun/nginx3]
85fcec7ef3ef: Pushed 
3e5288f7a70f: Pushed 
56bc37de0858: Pushed 
1c91bf69a08b: Pushed 
cb42413394c4: Pushed 
2.0: digest: sha256:0b159cd1ee1203dad901967ac55eee18c24da84ba3be384690304be93538bea8 size: 1362

以上则显示push成功！

4.DockerHub上查看

 二、阿里云镜像发布

1.登录阿里云，找到容器镜像服务，创建命名空间

 2.创建镜像仓库

 

3.查看创建后的镜像仓库

 4.在服务器上登录到阿里云

[root@yang ~]# sudo docker login --username=阿里云账号 registry.cn-hangzhou.aliyuncs.com
Password: 　　　　# 阿里云账号登录的密码
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

以上显示Login Succeeded，则代表登录成功

5.新增docker镜像

语法格式：

docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/docker2974/yang:[镜像版本号]

[root@yang ~]# docker tag f6d0b4767a6c registry.cn-hangzhou.aliyuncs.com/docker2974/yang:nginx1.0

[root@yang ~]# docker images
REPOSITORY                                          TAG                   IMAGE ID            CREATED             SIZE
nginx                                               latest                f6d0b4767a6c        2 weeks ago         133MB
xiguajun/nginx3                                     2.0                   f6d0b4767a6c        2 weeks ago         133MB
registry.cn-hangzhou.aliyuncs.com/docker2974/yang   nginx1.0              f6d0b4767a6c        2 weeks ago         133MB

6.上传（push）镜像到阿里云

语法格式：

docker push registry.cn-hangzhou.aliyuncs.com/docker2974/yang:[镜像版本号]

[root@yang ~]# docker push registry.cn-hangzhou.aliyuncs.com/docker2974/yang:nginx1.0
The push refers to repository [registry.cn-hangzhou.aliyuncs.com/docker2974/yang]
85fcec7ef3ef: Pushed 
3e5288f7a70f: Pushed 
56bc37de0858: Pushed
