docker 拉: operation not permitted

Question

在拉取一些 docker 镜像(但不是全部)时出现此错误:

failed to register layer: Error processing tar file(exit status 1): operation not permitted

例如: docker pull nginx 有效，但 docker pull redis 无效。

无论我使用属于 docker 组的用户，使用 sudo 或以 root 身份运行命令，我都会得到相同的结果。

如果我在 Debug模式下运行 dockerd，我会在日志中看到:

如果我在拉取图像时运行 watch -n 0 "sudo ls -lt/var/lib/docker/overlay2/"，我可以看到新文件夹出现(并在失败后消失) 并且 /var/lib/docker/overlay2/ 的权限是 root:root:700 所以我不认为这完全是权限问题。

这里有一些关于环境的细节:

我有一个运行 LXC 容器的 proxmox，我遇到了问题。容器本身正在运行 Debian 8。以下是各种版本:

编辑:这将在 2017 年 12 月 18 日之后通过 this merge 发布的 Moby 的任何版本中修复。 .完全融入 Docker 后将再次更新。

如果您的容器没有特权，这似乎是 Docker 的 overlay2 存储驱动程序的问题。这似乎不是 overlay ( GitHub issue ) 的问题。所以要么utilize the overlay storage driver而不是 overlay2，或者让你的容器有特权。
