创建registry私有仓库

docker container  run -itd --restart=always --name docker-registry -p 5000:5000 -v /data/docker-registry/config/config.yml:/etc/docker/registry/config.yml -v /data/docker-registry/registry/:/var/lib/registry registry:latest

config.yml里面的内容

version: 0.1
log:
  fields:
    service: registry
 storage:
  delete:  # 这是添加的
    enabled: true  # 这是添加的
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry
http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
    threshold: 3

**********************************************************

1. 查询registry的镜像

curl -s -XGET <protocol>://<私有仓库地址>/v2/_catalog
如：
curl -s -XGET http://192.168.192.250:5000/v2/_catalog
{"repositories":["centos7"]}

2. 查询具体镜像的tag

curl -s -XGET <protocol>://<私有仓库地址>/v2/<image_name>/tags/list
 如：
curl -s -XGET http://192.168.192.250:5000/v2/centos7/tags/list
{"name":"centos7","tags":["latest"]}

3. 查询具体镜像的digest,用于后面的删除镜像清单

curl  -I -s -XGET --header "Accept: application/vnd.docker.distribution.manifest.v2+json" <protocol>://<私有仓库地址>/v2/<image_name>/manifests/<tag>
如：
curl  -I -s -XGET --header "Accept: application/vnd.docker.distribution.manifest.v2+json" http://192.168.192.250:5000/v2/centos7/manifests/latest  | awk '/Docker-Content-Digest/{print $NF}'
sha256:285bc3161133ec01d8ca8680cd746eecbfdbc1faa6313bd863151c4b26d7e5a5

4. 根据具体镜像的digest删除清单

curl  -I -s -XDELETE --header "Accept: application/vnd.docker.distribution.manifest.v2+json" <protocol>://<私有仓库地址>/v2/<image_name>/manifests/<image_digest>
如:
curl  -I -s -XDELETE --header "Accept: application/vnd.docker.distribution.manifest.v2+json" http://192.168.192.250:5000/v2/centos7/manifests/sha256:285bc3161133ec01d8ca8680cd746eecbfdbc1faa6313bd863151c4b26d7e5a5

5. 删除文件系统内的镜像文件

docker container exec docker-registry /bin/registry garbage-collect /etc/docker/registry/config.yml
