docker?registry刪除遠(yuǎn)程倉庫鏡像實(shí)現(xiàn)方式

文章介紹如何清理Docker?Registry中堆積的鏡像,通過配置刪除功能、啟動(dòng)容器、查看鏡像信息并執(zhí)行刪除操作,同時(shí)提供基于web-ui的管理方案,優(yōu)化存儲(chǔ)空間使用

一、部署registry

1.1 開啟刪除功能

從registry容器里面將/etc/docker/registry/config.yml復(fù)制出來：

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

默認(rèn)config.yml內(nèi)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: 3

設(shè)置config.yml，在storage節(jié)點(diǎn)添加delete配置設(shè)置為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

1.2 啟動(dòng)registry容器

docker run -it -d --name registry -p 5000:5000 -v /opt/registry/:/var/lib/registry -v /etc/docker/registry/config.yml:/etc/docker/registry/config.yml --restart=always registry

1.3 查看鏡像名稱

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

1.4 查看鏡像tag

curl -s XGET localhost:5000/v2/test/tags/list|jq

1.5 查看鏡像reversion

ll /opt/registry/docker/registry/v2/repositories/test/_manifests/revisions/sha256/

#或者通過API獲取鏡像digest值
curl -i -sS -H 'Accept: application/vnd.docker.distribution.manifest.v2+json' 'http://localhost:5000/v2/test/manifests/latest'

1.6 刪除鏡像

curl -X DELETE localhost:5000/v2/test/manifests/sha256:703c4d81c860a7420749f6666aac348e1b62a07062865dfb91d4c30819483e70

1.7 垃圾回收

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

1.8 清除目錄

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

二、web-ui管理registry

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

2.1 部署docker-registry-web

docker pull hyper/docker-registry-web

（此配置中的任何屬性都可能被環(huán)境變量覆蓋，例如屬性registry.auth.enabled將變?yōu)镽EGISTRY_AUTH_ENABLED）

registry:
  # Docker registry url
  url: http://10.0.0.100:5000/v2
  # Docker registry fqdn
  name: localhost:5000
  # To allow image delete, should be false
  readonly: false
  auth:
    # Disable authentication
    enabled: false

使用 docker 運(yùn)行

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