Hi, ‘Exec format error’ might be related to processor architecture mismatch. Can you provide more detailed info on the environment that you utilise for building the image (host OS, VM OS, container OS) ?
Hi @benroberts23,
I recently hit this issue with my own application. After chatting with engineering this appears to be an issue with architecture as @Yannek mentioned.
App Platform is using gVisor for the execution of the applications under the hood. Looking at the gVisor docs, the following limitations would also apply to App Platform:
gVisor supports Linux ELF binaries.
Binaries run in gVisor should be built for the AMD64 or AArch64 CPU architectures.
In short, 32-bit binaries will fail to execute on App Platform. I would recommend looking for a 64-bit version of your executable if possible.
Hope this helps!
