1. 登錄阿里云Docker Registry

sudo docker login --username=xx@qq.com registry.cn-hangzhou.aliyuncs.com

2.將鏡像推送到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:[鏡像版本號(hào)]
$ 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:[鏡像版本號(hào)]
$ sudo docker push registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi:1.0

3.拉取

驗(yàn)證已push的阿里云docker image-先刪除已有的鏡像-再拉取鏡像-再創(chuàng)建容器

刪除鏡像:docker rmi f1eed31931c4

Error response from daemon: conflict: unable to delete f1eed31931c4 (must be forced) - image is referenced in multiple repositories

查看鏡像:docker images

對(duì)于被刪除的ImageID，這里存在多個(gè)REPOSITORY名字引用

即刪除時(shí)指定名稱，而不是IMAGE ID。

然后再刪除IMAGE ID就可以了

4.創(chuàng)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.

[root@MiWiFi-R2100-srv ~]# docker run --name ali-mywebapi -d -p 81:5000 f1eed31931c4
7ac0461905065b32acbda35c72f88fc28dccb1760837282565846b8b0ef62b7b

[root@MiWiFi-R2100-srv ~]# docker ps 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                  NAMES

[root@MiWiFi-R2100-srv ~]# 

綜上，為什么docker run --name ali-mywebapi -d -p 81:5000 registry.cn-hangzhou.aliyuncs.com/randyfield/mywebapi，daemon，會(huì)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'.原來是因?yàn)槊钪袥]有指定tag，我們?cè)趐ush時(shí)，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

打開阿里云的倉(cāng)庫(kù)

鏡像就80M，想象一下，如果我把發(fā)布的應(yīng)用做成鏡像，然后部署 docker pull,docker run，是不是很方便？
