删除docker私有仓库中的镜像

322321

docker私有仓库v2版本中的镜像，官方不建议删除，但是也提供了删除接口：

1 2 3

DELETE /v2/<name>/manifests/<reference> Host: <registry host> Authorization: <scheme> <token>

删除的原理就是把索引删掉，但磁盘上的数据是删不掉的。这是由于各个镜像之间的不同层共用的关系，可能导致删除一个镜像后其余的镜像也无法使用了。

  用python实现伪删除，代码如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

#-*- coding:utf-8 -*- #!/usr/bin/env python ''' Created on 2016.10.8 @desc: delete images from repo ''' import requests repo_ip = "172.16.4.254" repo_port = 5000 image_name = "oa" image_tag = "20161012" def deleteImagesFromRepo(repo_ip,repo_port,image_name,image_tag):     head = {'Accept': 'application/vnd.docker.distribution.manifest.v2+json'}     reg = "http://" + repo_ip + ":" + str(repo_port) + "/v2/"     res = requests.get(reg + image_name + "/manifests/" + image_tag,headers=head,verify=False)     manifest = res.headers['Docker-Content-Digest']     res2 = requests.delete(reg + image_name + "/manifests/"+manifest,verify=False)     if res2.status_code == 202:         print "delete %s success......"%(image_name+':'+image_tag)     else:         print "delete %s fail......"%(image_name+':'+image_tag) deleteImagesFromRepo(repo_ip,repo_port,image_name,image_tag)

运行结果如下：
