docker - Docker buildx - arm64 平台上没有这样的文件或目录

问题描述

我想通过使用buildx重建一个 docker 图像以添加对图像arranhs/duckerursim的支持 arm64v8 架构。

执行构建命令后

docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v8 -t my-user/my-repository:latest --push .

我收到此错误：

 => ERROR [linux/arm64 11/26] RUN mv /tmp/ursim* /tmp/ursim                                                                                                                                            0.0s

--------------------
  41 |     RUN rm /tmp/URSim-Linux.tar.gz
  42 |      # Rename the URSim folder to jus ursim
  43 | >>> RUN mv /tmp/ursim* /tmp/ursim
  44 |     
  45 |     RUN echo "**** Installing URSim ****"
--------------------
error: failed to solve: process "/bin/sh -c mv /tmp/ursim* /tmp/ursim" did not complete successfully: exit code: 1

前面步骤中的目录和文件好像没有创建？知道为什么吗？

我已经在 ubuntu 机器（我猜它使用 linux/amd64）上尝试了 docker 映像，该映像工作正常。但我想在一台与 Apple m1 芯片配合使用的 Macbook 上工作。

建造者

我这样创建了构建器：

# Init
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

# Create a builder
docker buildx create --name mybuilder --driver docker-container

# Switch to builder and checkout
docker buildx use mybuilder
docker buildx inspect --bootstrap

解决方案

RUN cd /tmp/ 不是在 dockerfile 中切换工作目录的正确方法，只会为当前命令切换它。你需要WORKDIR /tmp
