根因分析
容器镜像是为不同 CPU 架构(如 amd64)构建的,而宿主是 arm64,导致二进制文件的 ELF 格式不兼容。
English
The container image is built for a different CPU architecture (e.g., amd64) than the host (e.g., arm64), causing the binary's ELF format to be incompatible.
官方文档

-
拉取正确架构的镜像:'docker pull --platform linux/arm64 python:3.12-slim'。对于多架构构建,使用 'docker buildx build --platform linux/arm64 -t myapp .'
-
安装 QEMU 用户静态二进制文件以支持模拟:'docker run --privileged --rm tonistiigi/binfmt --install all'。然后使用 'docker run --platform linux/amd64 ...' 运行 amd64 镜像。
无效尝试
常见但无效的做法:
-
Reinstall Docker on the host
95% 失败
Reinstallation does not change the CPU architecture mismatch between image and host.
-
Add '--platform linux/amd64' to docker run
80% 失败
Forcing amd64 on an arm64 host without binfmt_misc or QEMU setup will still fail if the binary is not emulated.
-
Update Python inside the container via pip
90% 失败
The error is at the binary execution level, not Python version; pip cannot fix ELF format.
