我在云端构建 Docker 镜像时遇到了一个奇怪的权限错误。我切换到另一台机器，安装了 Gcloud，做了 gcloud init，一切都恢复了。
但是，我注意到在构建图像时，它花费了更长的时间，因为我没有启用 kaniko 缓存（我从这篇文章中了解到：gcloud rebuilds complete container but Dockerfile is the same, only the script has changed）
启用此功能后，我尝试重建我的最后一个图像和 bam，同样的错误消息：

任何人都知道为什么在启用 Kaniko 缓存时会失败？我讨厌不使用它，因为当它仍然有效时，它确实减少了创建 docker 映像所需的时间。
