frida_injector_inject_library_file_sync failed on Kubernetes POD PID

[janetat]

1. Question

1.1 frida_injector_inject_library_file_sync failed when injecting Kubernetes POD PID

frida-core-inject-example <POD PID on Host>:
Failed to inject: libelf.so.1: cannot open shared object file: No such file or directory

Why it relates to libelf.so.1?

1.2 Why frida -p <POD PID on Host> -l frida_inject.js loaded successfully?

2. frida-core-inject-example.c
