所以，我在GitHub上对一个开源项目HFS by rejetto进行了dockerizing。基本上你可以通过环境变量来配置它，使用HFS_=的形式（例如HFS_PORT=80）。
我想做的是在运行时通过Docker传递这些envs，但是奇怪的事情发生了：这个二进制文件只有在从容器内手动执行时才能获得envs，如果由docker在入口点自动运行，它会忽略它们，即使在同一个入口点脚本中，我可以看到它们被正确设置。
一点背景。

Dockerfile

# syntax=docker/dockerfile:1

ARG hfs_version=latest

FROM alpine AS build
WORKDIR src

ARG hfs_version
ENV HFS_VERSION=${hfs_version}

RUN apk --update --no-cache add \
  wget \
  zip

RUN wget https://github.com/rejetto/hfs/releases/download/${HFS_VERSION}/hfs-linux.zip \
  && unzip hfs-linux.zip

FROM node:20
WORKDIR hfs

COPY --from=build src/hfs ./hfs
COPY ./entrypoint.sh ./entrypoint.sh
RUN chmod +x ./hfs

ENTRYPOINT ["/bin/bash", "entrypoint.sh"]

字符串

入口点是jsut

#!/bin/bash

env | grep HFS
./hfs

型
当我构建并运行它时，使用：

• 第一个月
• docker run -it --rm -e HFS_PORT=3838 -p 0.0.0.0:80:3838 --name hfs gbrlfrc/hfs:1.0.0个

Docker在所有0.0.0.0上正确地暴露了端口80，内部绑定到3838，但二进制文件使用默认端口80启动，即使我在docker run中指定了HFS_PORT=3838作为env（输出如下）

# this is coming from my 'env | grep HFS' in the entrypoint
HFS_PORT=3838

现在，如果这是唯一的问题，我会认为是二进制文件没有正确读取env，但如果我在同一个运行容器中执行，并手动运行二进制文件：

~$ d exec -it hfs bash
root@be778aabb5c9:/hfs# ./hfs

# As you can see now the port is the correct one

我尝试在Dockerfile中直接运行二进制文件作为entrypoint或cmd，而不使用bash脚本，也遇到了同样的问题。像这样：

ENTRYPOINT ["./hfs"]

我也尝试在entrypoint脚本中源一个包含env的文件，但结果是一样的。有人有任何提示吗？这个问题让我抓狂。
