Question

我已经用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

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}

在dockerhub中，图像带有差异arch ：

但是当我在手臂群集中运行它时，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 build不是问题。问题是/usr/local/bin/chaos-operator是linux / amd64二进制文件，您正在尝试在linux / arm64上运行它。

Docker：standard_init_linux.go：211：exec用户进程导致“ exec格式错误”
