阿新 • • 發佈：2020-08-18
操作步驟#
- 通過環境變數修改預設配置，允許刪除
- 獲取image的sha值
- 進入registry容器中，執行垃圾回收
- 刪除殘留目錄
#環境變數 REGISTRY_STORAGE_DELETE_ENABLED=true 用於覆蓋預設設定
docker run -d -v /opt/registry:/var/lib/registry -e REGISTRY_STORAGE_DELETE_ENABLED=true -p 5000:5000 --restart=always --name registry registry:2
#宣告要刪除的映象名稱
image=...
#獲取sha
sha=`ls /opt/registry/docker/registry/v2/repositories/$image/_manifests/revisions/sha256`
#刪除 需替換registryurl
curl -XDELETE http://<registryurl>/v2/$image/manifests/sha256:$sha
#垃圾回收
docker exec -it registry sh
registry garbage-collect /etc/docker/registry/config.yml
exit
#刪除殘留目錄
rm -rf /opt/registry/docker/registry/v2/repositories/$image
