docker - Alpine Docker容器无法将UPX识别为可执行文件

Question

堆高车

我正在使用Docker容器化我的应用程序。在下面的stage中，我尝试使用UPX对其进行打包。

FROM alpine:3.8 AS compressor

# Version of upx to be used(without the 'v' prefix)
# For all releases, see https://github.com/upx/upx/releases
ARG UPX_VERSION=3.94

# Fetch upx, decompress it, make it executable.
ADD https://github.com/upx/upx/releases/download/v${UPX_VERSION}/upx-${UPX_VERSION}-amd64_linux.tar.xz /tmp/upx.tar.xy
RUN tar -xJOf /tmp/upx.tar.xy upx-${UPX_VERSION}-amd64_linux/upx > /usr/local/bin/upx \ 
 && chmod +x /usr/local/bin/upx

COPY --from=builder /usr/local/bin/ace /usr/local/bin/ace

RUN /usr/local/bin/upx --overlay=strip --best /usr/local/bin/ace

问题是当我生成图像时，出现以下错误:

The command '/bin/sh -c /usr/local/bin/upx --overlay=strip --best /usr/local/bin/ace' returned a non-zero code: 127

由于某些原因，容器无法将upx识别为可执行文件!谁能给我一些指导？

原来有一个UPX的apk软件包。更简单的安装方法是:

apk add upx
