Nexus 3 Compact blob 存储任务不会物理删除图像

Question

我们正在删除旧的 docker 图片，保留最后 10 张。我们尝试了 Compact blob store task 来物理删除它们，但是在 administration/Repository 设置中，Blob store 在删除图像后仍然显示相同的大小。

这是紧凑的 blob 存储日志：

Answer 1

Docker 图层可以在许多不同的图像之间共享，因此当您删除图像时，与图像关联的图层不会自动删除。首先运行一个 "docker - delete unused manifests and images" 任务，然后再次尝试运行压缩 blobstore。
