添加新的标签：cakin24/hello-world
[root@localhost ~]# docker tag 48b5124b2768 cakin24/hello-world
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
test/while latest cf1473016855 25 hours ago 118.8 MB
docker.io/httpd 2.2 3624a4b77da8 2 weeks ago 169.9 MB
docker.io/ubuntu latest 0ef2e08ed3fa 2 weeks ago 130 MB
cakin24/hello-world latest 48b5124b2768 9 weeks ago 1.84 kB
docker.io/hello-world latest 48b5124b2768 9 weeks ago 1.84 kB

三 上传镜像cakin24/hello-world:latest
[root@localhost ~]# docker push cakin24/hello-world:latest
The push refers to a repository [docker.io/cakin24/hello-world]
98c944e98de8: Mounted from library/hello-world
latest: digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7 size: 524
四 查看镜像是否传送成功
在Docker Hub上也可以看到自己的推送的tag

五 阿里云镜像加速
1）注册个帐号
https://dev.aliyun.com/search.html
阿里云会自动为用户分配一个镜像加速器的地址，登录后进入"管理中心"-->"加速器"，里面有分配给你的镜像加速器的地址以及各个环境的使用说明。
镜像加速器地址：https://XXXXXX.mirror.aliyuncs.com
2）针对Docker客户端版本大于1.10的用户
您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器：
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://
XXXXXX
.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
3）下载镜像时正常pull即可，比如：docker pull centos，docker会使用阿里云镜像进行加速。
六 怎样将本地镜像推送到阿里云
参考：https://ninghao.net/video/3780
1、在Docker镜像仓库管理页中的Namespace管理中增加namespace，笔者新增namespace为cakin24
2、在镜像列表中心增一个仓库，笔者新增仓库为nodejs-demo
3、登录阿里云的docker
，登录信息可从镜像信息中获取
[root@localhost ~]# sudo docker login --username=chengqiuming24 registry.cn-qingdao.aliyuncs.com
Password:
Login Succeeded
4、从阿里云（
https://dev.aliyun.com/search.html
）中随便获取一个nodejs-demo镜像
[root@localhost ~]# docker pull registry.cn-hangzhou.aliyuncs.com/qinyujia-test/nodejs-demo
Using default tag: latest
Trying to pull repository registry.cn-hangzhou.aliyuncs.com/qinyujia-test/nodejs-demo ...
latest: Pulling from registry.cn-hangzhou.aliyuncs.com/qinyujia-test/nodejs-demo
fdd5d7827f33: Pull complete
a3ed95caeb02: Pull complete
0f35d0fe50cc: Pull complete

5、查看本地镜像
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
test/while latest cf1473016855 3 days ago 118.8 MB
docker.io/centos latest 98d35105a391 6 days ago 192.5 MB
docker.io/httpd 2.2 3624a4b77da8 3 weeks ago 169.9 MB
docker.io/ubuntu latest 0ef2e08ed3fa 3 weeks ago 130 MB
docker.io/hello-world latest 48b5124b2768 9 weeks ago 1.84 kB
registry.cn-hangzhou.aliyuncs.com/qinyujia-test/nodejs-demo latest 905bb442e985 3 months ago 231.6 MB
docker.io/ubuntu 15.10 9b9cb95443b5 8 months ago 137.2 MB
6、新增一个镜像，取名tag为v1
[root@localhost ~]# sudo docker tag 905bb442e985 registry.cn-qingdao.aliyuncs.com/cakin24/nodejs-demo:v1
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
test/while latest cf1473016855 3 days ago 118.8 MB
docker.io/centos latest 98d35105a391 6 days ago 192.5 MB
docker.io/httpd 2.2 3624a4b77da8 3 weeks ago 169.9 MB
docker.io/ubuntu latest 0ef2e08ed3fa 3 weeks ago 130 MB
docker.io/hello-world latest 48b5124b2768 9 weeks ago 1.84 kB
registry.cn-hangzhou.aliyuncs.com/qinyujia-test/nodejs-demo latest 905bb442e985 3 months ago 231.6 MB
registry.cn-qingdao.aliyuncs.com/cakin24/nodejs-demo v1 905bb442e985 3 months ago 231.6 MB
docker.io/ubuntu 15.10 9b9cb95443b5 8 months ago 137.2 MB
7、将本地镜像推送到阿里云仓库
[root@localhost ~]# docker push registry.cn-qingdao.aliyuncs.com/cakin24/nodejs-demo:v1
The push refers to a repository [registry.cn-qingdao.aliyuncs.com/cakin24/nodejs-demo]
9a761a5d9ce3: Pushed
5f70bf18a086: Pushed
66cb9cbd7dad: Pushed
fa4fdea31e29: Pushed

8、验证推送是否成功。
