archlinux:base我正在Docker For Mac 中在完全空的 Mac 文件系统上构建图像（没有空格问题）。
df -h在构建时在 Dockerfile 的早期打印，显示如下：
#6 [ 3/34] RUN df -h

在下一个命令中，我执行 pacman -Syyu，它更新软件包。在此期间，我得到了这个：

#7 30.73 Errors occurred, no packages were upgraded.
#7 ERROR: executor failed running [/bin/sh -c pacman -Syyu sudo fish --noconfirm]: exit code: 1
但是，我没有看到任何空间问题。有可能与 相关吗tmpfs？
答案1
我实际上认为最后一个错误有点转移注意力
我认为这个问题是：https://github.com/moby/buildkit/issues/1267
