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

Build the image for the target platform architecture using docker build --platform linux/amd64 \(or arm64\), or fix CRLF line endings in entrypoint scripts to LF.

Journey Context:
A developer builds a Docker image on their new Apple Silicon \(M1/M2\) Mac and pushes it to a registry. When their Kubernetes cluster \(running on AMD64 nodes\) pulls and starts the pod, it immediately crashes with 'exec format error'. The developer suspects a corrupted image or a bug in the base image. They waste time rebuilding and pushing. Eventually, they realize that Docker on Apple Silicon defaults to building linux/arm64 images. The AMD64 node cannot execute the ARM64 binary. The fix is to explicitly specify the target architecture during the build using the --platform linux/amd64 flag, which utilizes QEMU emulation to cross-compile the image for the deployment target. Alternatively, if the base image is multi-arch, Docker will pull the correct one, but compiled binaries inside might still be ARM without the flag.
