Docker：“未找到”对于现有文件 [英] Docker: "not found" for an existing file

问题描述

我正在尝试在Docker容器中运行现有的二进制文件。

I'm trying to run an existing binary file in a Docker container.

当前文件夹中的文件：

$ ls .
app  Dockerfile  run.sh

Dockerfile：

Dockerfile:

FROM alpine:latest
COPY . /app/
RUN chmod +x /app/run.sh && chmod +x /app/app
WORKDIR /app
ENTRYPOINT ["./run.sh"]

run.sh：

#!/bin/sh
./app
ls

（ ls 命令为用于检查 app 是否不存在）

(The ls command is used to check if the app not exists)

Build命令和输出：

Build command and outputs:

$ sudo docker build . -t app_test
Sending build context to Docker daemon  3.427MB

Removing intermediate container 24ebb7500202
 ---> adcd6e94a37f
Successfully built adcd6e94a37f
Successfully tagged app_test:latest

运行命令：

$ sudo docker run -it app_test
./run.sh: line 2: ./app: not found
Dockerfile  app         run.sh

来自 ls的输出命令，我们可以找到 app 存在，但似乎 sh 找不到它。

From the output of ls command, we can find app exists, but it seems sh cannot find it.

我也尝试直接运行 ./ app 或使用 [ sh， run.sh ] 而不是 ENTRYPOINT 或 CMD ，但这没有帮助。

I also tried run ./app directly or use ["sh", "run.sh"] instead in ENTRYPOINT or CMD, but it doesn't help.

编辑：此 app 是封闭源代码软件，仅分发已编译的可执行文件。抱歉，我无法提供更多信息。

This app is a closed source software and only a compiled executable is distributed. I'm sorry I cannot provide more information.

推荐答案

如果 app 是一个shell脚本，则错误指向该脚本的第一行，例如如果 / bin / bash 在本地不存在，则＃！/ bin / bash 。

If app is a shell script, then the error refers to the first line of that script, e.g. #!/bin/bash if /bin/bash doesn't exist locally. Can also be windows linefeeds breaking that line.

如果 app 是可执行文件，则错误来自链接库。使用 ldd应用程序查看该二进制文件所针对的内容。对于高山，问题通常是glibc。

If app is an executable, then the error is from linked libraries. Use ldd app to see what that binary is linked against. With alpine, the issue is often glibc.
