开启镜像删除配置

spec:
  containers:
  - name: registry
    image: registry:2
    imagePullPolicy: IfNotPresent
    env:
    - name: REGISTRY_STORAGE_DELETE_ENABLED
      value: "true"
    ports:

删除单个镜像

获取待删除镜像版本的digest

curl -v --silent -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X GET  docker-registry:5100/v2/{repo_name}/manifests/{tag_version} 2>&1 | grep Docker-Content-Digest | awk '{print ($3)}'

删除

curl -v --silent -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X DELETE docker-registry:5100/v2/{repo_name}/manifests/{digest}

批量删除镜像脚本

网上搜到的脚本无法指定删除某一版本之前的镜像，所以稍微修改了一下，
由于是删除指定版本号之前的镜像，所以暂时无法同时删除多仓库

import requests
 
#仓库地址(自行修改)
hub = 'http://docker-registry:5100'
#仓库名(自行修改)
repo = 'test'
#删除limit_tag之前的版本, 如需删除5.10.1版本前的镜像, limit_tag = [5,10,1] (自行修改，可扩展4位或者其它多位版本号)
limit_tag = [0,0,0]
 
try:
   tag_list_url = '%s/v2/%s/tags/list' % (hub, repo)
   r1 = requests.get(url=tag_list_url)
   tag_list = r1.json().get('tags')
   #sort_tag_list = tag_list.sort()
   print(tag_list)
 
    for tag in tag_list:
        tag_arr = tag.split(".")
        for i, j in enumerate(tag_arr):
            if int(j) < int(limit_tag[i]):
                print(tag)
                get_info_url = '{}/v2/{}/manifests/{}'.format(hub, repo, tag)
                header = {"Accept": "application/vnd.docker.distribution.manifest.v2+json"}
                r2 = requests.get(url=get_info_url, headers=header, timeout=10)
                digest = r2.headers.get('Docker-Content-Digest')
                delete_url = '{}/v2/{}/manifests/{}'.format(hub, repo, digest)
                print(delete_url)
                r3 = requests.delete(delete_url)
            else:
                continue
 
except Exception as e:
    print(str(e))

调用docker-registry垃圾回收

进入docker-registry容器内部，手动调用垃圾回收

registry garbage-collect /etc/docker/registry/config.yml
