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

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"

Answer 1

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.
