在dotnet SDK和Docker容器上(On dotnet SDK and Docker containers)

这个问题应该是非常直截了当的。

假设您正在尝试运行Asp.Net Core Web Api。该应用程序将在Linux的干净安装中的Docker容器内运行（味道并不重要）。容器位于Kubernetes集群中的POD内，该集群带有docker工具。

Dockerfile需要针对特定版本的aspnetcore，看起来像这样：

FROM microsoft/aspnetcore:1.1 COPY . /app WORKDIR /app EXPOSE 5000/tcp ENV ASPNETCORE_URLS http://*:5000 ENTRYPOINT ["dotnet", "run"]

测试一下，我运行一个Docker命令就是这样......

所以我难倒的是这个; 我假设ENTRYPOINT定义中的“dotnet”命令正在运行.Net Core SDK。

如果此Linux代理上的容器没有安装SDK，或者安装的SDK是您尝试使用的SDK的旧版本，那么您将如何获得此版本的docker？本质上，ENTRYPOINT中的“dotnet”命令指的是一个不存在的程序？

我是否应该将SDK与容器打包在一起？如果是这样，该行是否应该读取ENTRYPOINT [“./dotnet”，“run”]因为它在Linux上？如果是这样，我还需要执行哪些其他步骤才能打包SDK？

我的假设是SDK已经在microsoft / aspnetcore：1.1的容器中打包了？如果是这样，有没有办法在ENTRYPOINT定义中引用打包的可执行文件？

任何见解将不胜感激！

This question should hopefully be pretty straight forward.

Say you're trying to run an Asp.Net Core Web Api. The app will run inside of a Docker container inside a clean installation of Linux (flavor doesn't really matter). The container lives inside a POD in a Kubernetes cluster which comes with docker tools.

The Dockerfile needs to target a specific version of aspnetcore and looks something like this:

FROM microsoft/aspnetcore:1.1 COPY . /app WORKDIR /app EXPOSE 5000/tcp ENV ASPNETCORE_URLS http://*:5000 ENTRYPOINT ["dotnet", "run"]

Testing things out, I run a Docker command as so...

So what I'm stumped on is this; that "dotnet" command in the ENTRYPOINT definition I'm assuming is running the .Net Core SDK.

If the container on this Linux agent does not have the SDK installed, or the SDK that is installed is an older version that the SDK that you're trying to use, how exactly would you get this to docker build? Essentially that "dotnet" command in the ENTRYPOINT is referring to a program that doesn't exist?

Am I supposed to package the SDK with the container as well? If so, should that line read ENTRYPOINT ["./dotnet", "run"] because it's on Linux? Also if so, what other steps do I need to perform to package the SDK?

My assumption was that the SDK is packaged already in the container with microsoft/aspnetcore:1.1? If so, is there a way to reference the packged executable in the ENTRYPOINT definition?

Any insight would be greatly appreciated!
