删除docker私有仓库中的镜像
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:
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:
#-*- 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:
