1. 将自己创建的镜像发布到阿里云仓库：

1.1 在阿里云容器镜像服务中创建个人实例

1.2 进入个人实例，创建命名空间

1.3 创建镜像仓库，会产生一些阿里云为你生成的命令

操作指南：

1. 登录阿里云Docker Registry
$ docker login --username=messi9**** registry.cn-hangzhou.aliyuncs.com
用于登录的用户名为阿里云账号全名，密码为开通服务时设置的密码。

您可以在访问凭证页面修改凭证密码。

2. 从Registry中拉取镜像
$ docker pull registry.cn-hangzhou.aliyuncs.com/yhx94/yhx94:[镜像版本号]
3. 将镜像推送到Registry
$ docker login --username=messi9**** registry.cn-hangzhou.aliyuncs.com
$ docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/yhx94/yhx94:[镜像版本号]
$ docker push registry.cn-hangzhou.aliyuncs.com/yhx94/yhx94:[镜像版本号]
请根据实际镜像信息替换示例中的[ImageId]和[镜像版本号]参数。

4. 选择合适的镜像仓库地址
从ECS推送镜像时，可以选择使用镜像仓库内网地址。推送速度将得到提升并且将不会损耗您的公网流量。

如果您使用的机器位于VPC网络，请使用 registry-vpc.cn-hangzhou.aliyuncs.com 作为Registry的域名登录。

5. 示例
使用"docker tag"命令重命名镜像，并将它通过专有网络地址推送至Registry。

$ docker images
REPOSITORY                                                         TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
registry.aliyuncs.com/acs/agent                                    0.7-dfb6816         37bb9c63c8b2        7 days ago          37.89 MB
$ docker tag 37bb9c63c8b2 registry-vpc.cn-hangzhou.aliyuncs.com/acs/agent:0.7-dfb6816
使用 "docker push" 命令将该镜像推送至远程。

$ docker push registry-vpc.cn-hangzhou.aliyuncs.com/acs/agent:0.7-dfb6816

1.4 将之前commit的包含vim命令的ubuntu推送到阿里云镜像及从阿里云拉取：

在push的过程中，可以看到，我们push的with-vim镜像分为了2个文件：9a91045e4b63和9f54eef41275，而9f54eef41275文件大小是72.8MB，就是原来的ubuntu的镜像，更加证明了，镜像是基于分层文件系统的。

拉取不多演示

2. 将镜像上传到私服

2.1 下载docker registry

[root@yhx ~]# docker pull registry
Using default tag: latest
latest: Pulling from library/registry

with-vim/with-vim                               1.0       9b6363fb0c60   36 minutes ago   175MB

[root@yhx ~]# 

2.2 运行私有库，相当于本地有一个docker hub

默认情况，仓库被创建在容器的/var/lib/registry目录下，建议自行用容器卷映射，方便于宿主机联调

[root@yhx ~]# docker run -d -p 5000:5000 -v /zzyyuser/myregistry:/tmp/registry --privileged=true registry
c5953d191749db444c8bcb4f7b6335bd4fae6565e5a649d1be2f41f16c722aac
[root@yhx ~]# docker ps
CONTAINER ID   IMAGE      COMMAND                  CREATED          STATUS          PORTS                                       NAMES
c5953d191749   reg istry   "/entrypoint.sh /etc…"   12 seconds ago   Up 11 seconds   0.0.0.0:5000->5000/tcp, :::5000->5000/tcp   naughty_napier

2.3 查看私服是否上传过镜像：

[root@yhx ~]# curl -GET http://**.**.**.**:5000/v2/_catalog
{"repositories":[]}

2.4 修改镜像为符合规范的tag：

docker tag 镜像名:tag Host:Port/Repository:tag

[root@yhx ~]# docker tag with-vim/with-vim:1.0 **.**.**.**:5000/with-vim:1.0
[root@yhx ~]# docker images
REPOSITORY                                      TAG       IMAGE ID       CREATED          SIZE
**.**.**.**:5000/with-vim                    1.0       9b6363fb0c60   48 minutes ago   175MB
with-vim/with-vim                               1.0       9b6363fb0c60   48 minutes ago   175MB
registry.cn-hangzhou.aliyuncs.com/yhx94/yhx94   1.0       9b6363fb0c60   48 minutes ago   175MB

tomcat                                          latest    fb5657adc892   2 months ago     680MB
redis                                           latest    7614ae9453d1   2 months ago     113MB

ubuntu                                          latest    ba6acccedd29   5 months ago     72.8MB

[root@yhx ~]# 

2.5 修改配置文件使之支持http

cd /etc/docker/daemon.json

添加：“insecure-registries”:[172.16.162.115:5000]，注意加逗号

{
  "registry-mirrors": ["https://jdhg9s8z.mirror.aliyuncs.com"],
  "insecure-registries":[内网ip:5000]
}

2.6 推送镜像到私服

[root@yhx docker]# docker push 内网id:5000/with-vim:1.0
The push refers to repository [内网id:5000/with-vim]
9a91045e4b63: Pushed 
9f54eef41275: Pushed 
1.0: digest: sha256:6ab5e018896a24c1673c9a365ba0c2909c67d789993e905fbb971289b500dc71 size: 741
[root@yhx docker]# 

2.7 验证

[root@yhx docker]# curl -GET http://内网id:5000/v2/_catalog
{"repositories":["with-vim"]}
[root@yhx docker]# 

2.8 删除本地镜像并从私服拉取

删除本地镜像，不多展示

拉取：

[root@yhx docker]# docker pull 内网id:5000/with-vim:1.0
1.0: Pulling from with-vim
