Docker build 与 Docker run 的行为不一样

转载作者：行者123 更新时间：2023-12-05 06:12:21

我尝试使用 Archlinux 基础构建 Docker 镜像。问题是我在构建 docker 镜像和手动执行命令时没有得到相同的结果。

$ cat Dockerfile

这失败了，我不明白为什么。

新容器中的相同命令:

$ docker run --rm archlinux/base pacman -Suy --noconfirm --noprogressbar

它们之间有什么区别？我怎样才能拥有一个有效的 Dockerfile？

谢谢

PS:这不是空间问题(df -h 没有向我显示接近满的“Use%”)

最佳答案

正如 larsks 所注意到的，这似乎与 buildkit 有关。 /etc/resolv.conf 和 /etc/hosts 在使用 buildkit 时以只读方式挂载。 pacman 似乎试图更新这些文件，导致您看到的错误。

作为解决方法，您可以设置 DOCKER_BUILDKIT environment variable从 1 到 0 禁用它。例如:

DOCKER_BUILDKIT=0 docker 构建。
