如何在 Dockerfile 中为 ENTRYPOINT 指定工作目录 [英] How to specify working directory for ENTRYPOINT in Dockerfile

问题描述

Docker 映像(基于 Windows)在 C:App 处包含一个应用程序目录.该目录内有几个子文件夹和文件，包括一个名为 process.bat 的批处理文件.Dockerfile(用于构建镜像)的结尾是这样的:

The Docker image (Windows-based) includes an application directory at C:App. Inside that directory reside several sub-folders and files, including a batch file called process.bat. The Dockerfile (used to build the image) ends like this:

ENTRYPOINT [ "C:\App\process.bat" ]

当我使用以下命令实例化此图像时:docker run company/app，批处理文件运行，但在 C:App 被引用.本质上，工作目录仍然是来自 Docker 容器入口点的 C:.

When I instantiate this image using the command: docker run company/app, the batch file runs, but it fails at the point where other files under C:App are referenced. Essentially, the working directory is still C: from the Docker container's entry-point.

有没有办法在 Dockerfile 中设置工作目录?确实存在一些替代方案:

Is there a way to set the working directory within the Dockerfile? Couple of alternatives do exist:

• 将 -w C:App 添加到 docker run
• 在批处理文件中，我可以在开头添加一行cd/D C:App

• Add -w C:App to the docker run
• In the batch file, I can add a line at the beginning cd /D C:App

但是有没有办法在 Dockerfile 中指定工作目录?

But is there a way to specify the working directory in the Dockerfile?

推荐答案

WORKDIR/App 是一个可以在 dockerfile 中用于更改工作目录的命令.

WORKDIR /App is a command you can use in your dockerfile to change the working directory.
