如何使Shell脚本指向.dll?(Docker ENTRYPOINT) [英] How can I have a shell script point to a .dll? (Docker ENTRYPOINT)

问题描述

我正在使用Docker部署.NET Core应用程序.默认情况下，应用程序的DockerFile中的 ENTRYPOINT 类似于:

I am using Docker to deploy a .NET Core application. By default, the ENTRYPOINT in the DockerFile for an application is something like:

ENTRYPOINT ["dotnet"，"applicationStartingPoint.dll"]

但是，在应用程序启动之前，我需要在容器中执行shell脚本.为此， CMD 名称不适用于我，因此我需要将shell脚本用作 ENTRYPOINT ，然后通过DLL启动该应用程序.

However, I need to have a shell script execute in the container before the application begins. The CMD designation is not working for me for this purpose, so I need to have a shell script as my ENTRYPOINT and then have that start the application by the DLL.

您可以提供的任何见解将大有裨益.

Any insight you could provide would be greatly beneficial.

推荐答案

您可以简单地创建一个名为 entrypoint.sh 的脚本.在此脚本中，您可以执行所需的任何操作，然后调用命令以启动应用程序.所以:

You can simply create a script called entrypoint.sh. Inside of this script you can do whatever you want, then call the command to start the application. So:

entrypoint.sh :

#!/usr/bin/env sh

... my crazy pre-script

dotnet applicationStartingPoint.dll

Dockerfile :

COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]

更新:我已向Dockerfile添加了如何在构建文件时将文件复制到容器并提供必要的权限.

UPDATE: I've added to the Dockerfile how you can copy the file to the container while building it and also give the necessary permissions.
