查看单个镜像信息
http://ip:port/v2/image_name/tags/list
如
浏览器访问 http://xxx.xxx.xxx.xxx:5000/v2/nginx/tags/list {"name":"nginx","tags":["latest"]}
http://xxx.xxx.xxx.xxx:5000/v2/nginx/manifests/latest
docker run -d -v /app/registry:/var/lib/registry -p 5000:5000 -e REGISTRY_STORAGE_DELETE_ENABLED=true --restart=always --name registry registry:v1.0
删除
方案一：
用官方模块delete_docker_registry_image
1、添加 模块 delete_docker_registry_image
官方操作文档：https://github.com/burnettk/delete-docker-registry-image
2、删除之前需要先添加环境变量
[root@1a01vlb5970zzzz repositories]# cat /etc/profile|grep regis export REGISTRY_DATA_DIR=/app/registry/docker/registry/v2
注意：如果需要远程删除，就需要在远程用户的HOME目录的.bashrc中添加需要的环境变量
delete_docker_registry_image --image wurstmeister/kafka # 删除镜像之后如果不重启，重新上传会报层数据已存在，必须重启才能重新上传 systemctl restart docker
方案二：
# --header "Accept: application/vnd.docker.distribution.manifest.v2+json" 这个header 是必须要加的，不加的话Content-Type 是v1+prettyjws，获取的digest是错误的！！ headers = {‘Accept‘:‘application/vnd.docker.distribution.manifest.v2+json‘} url = "http://" + self.registry + "/v2/" + args[‘image_name‘] +‘/manifests/‘ + args[‘tag‘] print(url) getres =requests.get(url,headers=headers) digest = getres.headers[‘Docker-Content-Digest‘] deleteurl = "http://" + self.registry + "/v2/" + args[‘image_name‘] +‘/manifests/‘ + digest delres = requests.delete(deleteurl,headers=headers) print(delres.content) print(delres.headers) print(delres.status_code) ?
# 垃圾回收
docker exec -it da33dd273367 bin/registry garbage-collect /etc/docker/registry/config.yml &>/dev/null
问题：重新上传报错层存在，并且查询私有仓库镜像发现没上传成功
