linux - Docker:standard_init_linux.go:211:exec 用户进程导致 "exec format error"

Question

我使用 buildx 命令创建了一个 docker multiarch 镜像。

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

构建/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}

在 dockerhub图像带有差异 arch :
但是当我在 arm 集群中运行它时，它显示错误:

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

有人可以帮忙吗？

Docker multiarch 构建不是问题。问题是/usr/local/bin/chaos-operator是一个 linux/amd64 二进制文件，您正试图在 linux/arm64 上运行它。
