[bug\_fix] standard\_init\_linux.go:228: exec user process caused: exec format error

Build the image for the target platform architecture using --platform=linux/amd64 in the FROM instruction or during docker build, or fix CRLF line endings in shell scripts.

Journey Context:
A developer builds a Docker image on their Apple Silicon \(ARM64\) Mac and pushes it to a Kubernetes cluster running on AMD64 nodes. The pod crashes with 'exec format error'. The developer spends hours checking base image versions and shell script syntax, assuming a corrupted build. They finally inspect the image locally using docker inspect and notice Architecture: arm64. The root cause is that Docker built the image natively for ARM. The fix is to explicitly specify the target architecture in the Dockerfile using FROM --platform=linux/amd64 node:16 or by running docker build --platform linux/amd64. This instructs BuildKit to pull the AMD64 variant of the base image and emulate or cross-compile the build, ensuring the resulting binary is compatible with the AMD64 deployment target.
