Docker: standard_init_linux.go:211: exec user process caused "exec format error"

Question

I have created one docker multiarch image with buildx command.

sudo docker buildx build -f build/Dockerfile --platform linux/arm/v7,linux/arm64,linux/amd64 -t uditgaurav/chaos-operator:v3 . --push

build/Dockerfile:

FROM golang:1.13 

ENV GO111MODULE=on \
    CGO_ENABLED=1 

ENV OPERATOR=/usr/local/bin/chaos-operator \
    USER_UID=1001 \
    USER_NAME=chaos-operator

# install operator binary
COPY build/_output/bin/chaos-operator ${OPERATOR}

COPY build/bin /usr/local/bin

RUN  /usr/local/bin/user_setup

RUN export GOOS=$(echo ${TARGETPLATFORM} | cut -d / -f1) && \
    export GOARCH=$(echo ${TARGETPLATFORM} | cut -d / -f2) && \
    GOARM=$(echo ${TARGETPLATFORM} | cut -d / -f3 | cut -c2-)

ENTRYPOINT ["/usr/local/bin/entrypoint"]

USER ${USER_UID}

In dockerhub the images came with diff arch:

But when I ran it in arm clusters it is showing error:

standard_init_linux.go:211: exec user process caused "exec format error"

Docker multiarch build is not the problem. The problem is that /usr/local/bin/chaos-operator is an linux/amd64 binary and you're trying to run it on linux/arm64.

I'm also getting the same error while trying to build an image on ARM664. Could you please help me?

I'm guessing your somewhere during your build you're trying to run an executable not compiled for that architecture.

You won't get any help on SO by asking for it in a comment to an answer to another question, even if it is tangentially related. If you want assistance, ask a separate question and put your Dockerfile, description of the issue and any other relevant information in it.
