1. 登录阿里云Docker Registry
sudo docker login --username=xx@qq.com registry.cn-hangzhou.aliyuncs.com
2.将镜像推送到Registry
$ sudo docker login --username=xx@qq.com registry.cn-hangzhou.aliyuncs.com
# 命令: sudo docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:[镜像版本号]
$ sudo docker tag f1eed31931c4 registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:1.0
# 命令: sudo docker push registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:[镜像版本号]
$ sudo docker push registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:1.0
3.拉取
验证已push的阿里云docker image-先删除已有的镜像-再拉取镜像-再创建容器
删除镜像:docker rmi f1eed31931c4
Error response from daemon: conflict: unable to delete f1eed31931c4 (must be forced) - image is referenced in multiple repositories
查看镜像:docker images

对于被删除的ImageID，这里存在多个REPOSITORY名字引用
-
即删除时指定名称，而不是IMAGE ID。
-
然后再删除IMAGE ID就可以了

拉取：sudo docker pull registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:1.0
[root@MiWiFi-R2100-srv ~]# sudo docker pull registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:1.0

4.创建容器
docker run --name ali-mywebapi -d -p 81:5000 f1eed31931c4
[root@MiWiFi-R2100-srv ~]# docker run --name ali-mywebapi -d -p 81:5000 registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi
Unable to find image 'registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:latest' locally
docker: Error response from daemon: manifest for registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:latest not found: manifest unknown: manifest unknown.
See 'docker run --help'.
[root@MiWiFi-R2100-srv ~]# docker rm -f ali-mywebapi
Error: No such container: ali-mywebapi
[root@MiWiFi-R2100-srv ~]# docker run --name ali-mywebapi -d -p 81:5000 registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi
Unable to find image 'registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:latest' locally
docker: Error response from daemon: manifest for registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:latest not found: manifest unknown: manifest unknown.
See 'docker run --help'.
[root@MiWiFi-R2100-srv ~]# docker run --name ali-mywebapi -d -p 81:5000 f1eed31931c4
7ac0461905065b32acbda35c72f88fc28dccb1760837282565846b8b0ef62b7b
[root@MiWiFi-R2100-srv ~]# docker ps

[root@MiWiFi-R2100-srv ~]#
综上，为什么docker run --name ali-mywebapi -d -p 81:5000 registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi，daemon，会提示，Unable to find image 'registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:latest' locally docker: Error response from daemon: manifest for registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:latest not found: manifest unknown: manifest unknown. See 'docker run --help'.原来是因为命令中没有指定tag，我们在push时，是有指定tag的。
docker run --name ali-mywebapi -d -p 81:5000 registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:1.0
5.想象
打开阿里云的仓库
镜像就80M，想象一下，如果我把发布的应用做成镜像，然后部署 docker pull,docker run，是不是很方便？
