在 Alpine Linux Docker 的路径中找不到已安装的 Go 二进制文件 [英] Installed Go binary not found in path on Alpine Linux Docker

问题描述

我有一个 Go 二进制文件，我想在 Alpine Docker 映像上运行.

I've got a Go binary I'm trying to run on the Alpine Docker image.

这适用于 Docker Go 二进制文件.

This works fine for the Docker Go binary.

docker run -it alpine:3.3 sh
apk add --no-cache curl

DOCKER_BUCKET=get.docker.com
DOCKER_VERSION=1.9.1
curl -fSL "https://${DOCKER_BUCKET}/builds/Linux/x86_64/docker-$DOCKER_VERSION" -o /usr/local/bin/docker
chmod +x /usr/local/bin/docker
docker help
Usage: docker [OPTIONS] COMMAND [arg...]
...

但是，对于我想要安装的 Go 二进制文件.

However, for the Go binary I want to install.

RACK_BUCKET=ec4a542dbf90c03b9f75-b342aba65414ad802720b41e8159cf45.ssl.cf5.rackcdn.com
RACK_VERSION=1.1.0-beta1
curl -fSL "https://${RACK_BUCKET}/${RACK_VERSION}/Linux/amd64/rack" -o /usr/local/bin/rack
chmod +x /usr/local/bin/rack

rack help
sh: rack: not found

/usr/local/bin/rack help
sh: /usr/local/bin/rack: not found

ls -al /usr/local/bin/
total 43375
drwxr-xr-x    2 root     root          1024 Jan 11 18:10 .
drwxr-xr-x    8 root     root          1024 Jan 11 18:09 ..
-rwxr-xr-x    1 root     root      30222575 Jan 11 18:09 docker
-rwxr-xr-x    1 root     root      14190576 Jan 11 18:10 rack

which rack
/usr/local/bin/rack

我认为它可能与这个答案有关，但我在运行时没有遇到同样的错误<代码>ldd.

I thought it might have something to do with this answer but I don't get the same error when running ldd.

ldd /usr/local/bin/rack
    /lib64/ld-linux-x86-64.so.2 (0x7fdd15cd0000)
    libpthread.so.0 => /lib64/ld-linux-x86-64.so.2 (0x7fdd15cd0000)
    libc.so.6 => /lib64/ld-linux-x86-64.so.2 (0x7fdd15cd0000)

在 Alpine Linux Docker 的路径中没有找到关于这个安装的 Go 二进制文件的任何想法?

Any idea with this installed Go binary is not found in path on Alpine Linux Docker?

推荐答案

RUN mkdir /lib64 && ln -s /lib/libc.musl-x86_64.so.1 /lib64/ld-linux-x86-64.so.2

由于 musl 和 glibc 是兼容的，您可以制作此符号链接，它将修复缺少的依赖项.

Since the musl and glibc so are compatible, you can make this symlink and it will fix the missing dependency.
