linux卸载docker离线_删除Docker私有仓库中的镜像

Docker私有仓库v2版本中的镜像&＃xff0c;官方不建议删除&＃xff0c;但是也提供了删除接口&＃xff1a;

DELETE /v2//manifests/

Host:

Authorization:

删除的原理就是把索引删掉&＃xff0c;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&＃xff0c;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&＃xff0c;代码如下&＃xff1a;

#-*- coding:utf-8 -*-

#!/usr/bin/env python

&＃39;&＃39;&＃39;

Created on 2016.10.8

&＃64;desc: delete images from repo

&＃39;&＃39;&＃39;

import requests

repo_ip &＃61; "172.16.4.254"

repo_port &＃61; 5000

image_name &＃61; "oa"

image_tag &＃61; "20161012"

def deleteImagesFromRepo(repo_ip,repo_port,image_name,image_tag):

head &＃61; {&＃39;Accept&＃39;: &＃39;application/vnd.docker.distribution.manifest.v2&＃43;json&＃39;}

reg &＃61; "http://" &＃43; repo_ip &＃43; ":" &＃43; str(repo_port) &＃43; "/v2/"

res &＃61; requests.get(reg &＃43; image_name &＃43; "/manifests/" &＃43; image_tag,headers&＃61;head,verify&＃61;False)

manifest &＃61; res.headers[&＃39;Docker-Content-Digest&＃39;]

res2 &＃61; requests.delete(reg &＃43; image_name &＃43; "/manifests/"&＃43;manifest,verify&＃61;False)

if res2.status_code &＃61;&＃61; 202:

print "delete %s success......"%(image_name&＃43;&＃39;:&＃39;&＃43;image_tag)

else:

print "delete %s fail......"%(image_name&＃43;&＃39;:&＃39;&＃43;image_tag)

deleteImagesFromRepo(repo_ip,repo_port,image_name,image_tag)

运行结果如下&＃xff1a;
