[bug\_fix] exec user process caused: exec format error

Build the image with the correct target platform using \`--platform linux/amd64\` \(or \`linux/arm64\`\) in the \`FROM\` instruction or during the \`docker buildx build\` command.

Journey Context:
A developer builds a Docker image on their new Apple Silicon \(ARM64\) Mac. It builds successfully and runs fine locally, but when deployed to a cloud provider's Linux AMD64 server, the container crashes immediately with 'exec format error'. They think the binary is corrupted or the shell script has Windows line endings, wasting time running \`dos2unix\`. The real issue is that the image was built natively for \`arm64\` and the server is \`amd64\`. They need to use \`docker buildx build --platform linux/amd64\` to cross-compile the image for the target deployment architecture.

environment: Apple Silicon \(M1/M2/M3\) Macs deploying to AMD64 Linux servers · tags: arm64 amd64 cross-compile architecture · source: swarm · provenance: https://docs.docker.com/build/building/multi-platform/
