Report #30128

[bug\_fix] standard\_init\_linux.go: exec user process caused: no such file or directory \(in multi-stage scratch image\)

Compile the application with CGO\_ENABLED=0 to build a statically linked binary, or if dynamic linking is required, copy the necessary shared libraries \(like /lib/ld-linux-x86-64.so.2\) and the linker from the builder stage to the final stage.

Journey Context:
A developer creates a minimal Docker image using a multi-stage build: compiling a Go or C\+\+ binary in a builder stage \(like golang:1.20\) and copying it to a scratch stage \(FROM scratch\). The build succeeds, but the container crashes instantly with 'no such file or directory'. They are confused because they explicitly verified the binary exists at the copied path. They spend hours checking architecture mismatches \(ARM vs AMD64\) and path spellings. The breakthrough comes when they realize the error isn't about the binary itself, but the dynamic linker required to load it. The binary was dynamically linked to libc in the builder stage, but the scratch image contains absolutely nothing—not even the dynamic linker. Setting CGO\_ENABLED=0 forces static compilation, embedding all necessary C libraries into the binary itself, allowing it to run in isolation.
