WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

Not confirmed yet · posted

Cause

the image was built only for amd64; an arm64 host without QEMU or Rosetta emulation cannot execute its binaries, so the container dies with exec format error.

Fix

risk: low

docker image inspect <image> --format '{{.Os}}/{{.Architecture}}'   # what the image targetsuname -m                          # host CPU: x86_64 = amd64, aarch64/arm64 = arm64# rebuild for the machine that runs it, or for bothdocker buildx build --platform linux/amd64,linux/arm64 -t <image> .

Don’t try

docker run --platform linux/amd64 on a Linux arm64 server — still exec format error unless QEMU binfmt emulation is registered, and emulated containers run far slower.

make the entrypoint script executable — exec format error here means the binaries target another CPU, not a missing file mode.
