Question

Ubuntu 18.04上的NVidia Jetson Nano完成了standard_init_linux.go:211: exec user process caused "exec format error"的docker运行，但是某些图像运行得很好。

Answer 1

看起来docker run命令可以很好地拉django映像，但是运行部分失败。

Django:latest泊坞镜映像是仅x86-64的映像。但是，当您使用Jetson Nano（手臂架构）时，应该找到（或构建）arm64兼容的docker映像，而不是x86-64。

您的示例中另外两个没有出现相同错误的命令仅在执行拉取部分。但是它们很可能仍然可以正常运行，因为它们都Arm64兼容。

您可以在dockerhub上的图像下方找到标签。
