docker register 删除镜像

开启删除功能

从registry容器里面将/etc/docker/registry/config.yml复制出来。

docker cp registry:/etc/docker/registry/config.yml .1

默认config.yml内容如下：

version: 0.1
log:
  fields:
    service: registry
storage:
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry
http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
    threshold: 3123456789101112131415161718

设置config.yml，在storage节点添加delete配置设置为true。

version: 0.1
log:
  fields:
    service: registry
storage:
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry
  delete:
    enabled: true
http:
  addr: :5000
  headers:
    X-Content-Type-Options: [nosniff]
health:
  storagedriver:
    enabled: true
    interval: 10s
    threshold: 31234567891011121314151617181920

将修改过的config.yml覆盖容器里面的。

docker cp config.yml registry:/etc/docker/registry/config.yml

重启仓库容器

docker restart registry

查看镜像名

curl -s -XGET 172.27.36.8:5000/v2/_catalog | python -mjson.tool

查看镜像tag

curl -s -XGET 172.27.36.8:5000/v2/test_his_platform_global_api_2022-02-18-02-46/tags/list|python -mjson.tool

{
    "name": "test_his_platform_global_api_2022-02-18-02-46",
    "tags": [
        "latest"
    ]
}

查看镜像reversion


ls /var/lib/docker/volumes/78c1937e0a8c810c8e4249d0245b4777ac4e66428519376712d99b811e559758/_data/docker/registry/v2/repositories/test_his_platform_global_api_2022-02-18-02-46/_manifests/revisions/sha256

703c4d81c860a7420749f6666aac348e1b62a07062865dfb91d4c30819483e70

## 或者通过API获取镜像digest值
curl -i -sS -H 'Accept: application/vnd.docker.distribution.manifest.v2+json' 'https://172.27.36.8:5000/v2/test_his_platform_global_api_2022-02-18-02-46/manifests/latest'

删除镜像：

curl -X DELETE 172.27.36.8:5000/v2/test_his_platform_global_api_2022-02-18-02-46/manifests/sha256:703c4d81c860a7420749f6666aac348e1b62a07062865dfb91d4c30819483e70

垃圾回收：

docker exec -it 9658cbb01b13 registry garbage-collect /etc/docker/registry/config.yml

清除目录：

rm -rf /var/lib/docker/volumes/78c1937e0a8c810c8e4249d0245b4777ac4e66428519376712d99b811e559758/_data/docker/registry/v2/repositories/test_his_platform_global_api_2022-02-18-02-46

web-ui管理registry：

docker hub 地址：https://hub.docker.com/r/hyper/docker-registry-web

docker pull hyper/docker-registry-web

无身份验证，带配置文件
创建配置文件config.yml

（此配置中的任何属性都可能被环境变量覆盖，例如属性registry.auth.enabled将变为REGISTRY_AUTH_ENABLED）

registry:
  # Docker registry url
  url: http://registry-srv:5000/v2
  # Docker registry fqdn
  name: localhost:5000
  # To allow image delete, should be false
  readonly: false
  auth:
    # Disable authentication
    enabled: false

使用 docker 运行

docker run -p 5000:5000 --name registry-srv -d registry:2
docker run -it -p 8083:8080 --name registry-web --link registry-srv -v $(pwd)/config.yml:/conf/config.yml:ro hyper/docker-registry-web

Web UI 将在http://localhost:8083
