VS 2017添加> Docker支持中断了构建-"CleanWorkspace"任务意外失败(控制台应用程序) [英] VS 2017 Add > Docker Support breaks build - "CleanWorkspace" task failed unexpectedly (console app)

问题描述

首先，我正在使用.NET 4.6.1.装有VS 2017的Docker不能与.NET Core一起使用吗?

First off I'm using .NET 4.6.1. Does Docker with VS 2017 not work with anything but .NET Core?

我从上下文菜单中使用了新功能Add > Docker Support，它创建了一堆文件.这是我的Dockerfile(因为它是自动创建的，所以没有碰过它):

I used the new feature Add > Docker Support from the context menu, and it created a bunch of files. Here's my Dockerfile (haven't touched it since it was auto-created):

FROM microsoft/windowsservercore
ARG source
WORKDIR /app
COPY ${source:-obj/Docker/publish} .
ENTRYPOINT ["C:\app\nameofmyapp.exe"]

构建时，出现以下错误:

When I build, I get the following error:

"CleanWorkspace"任务意外失败. Microsoft.DotNet.Docker.CommandLineClientException:撰写文件 '... \ docker-compose.yml' 无效，因为:services.pas.parsemicroservice.build.context 包含null，这是无效的类型，应为字符串.

The "CleanWorkspace" task failed unexpectedly. Microsoft.DotNet.Docker.CommandLineClientException: The Compose file '...\docker-compose.yml' is invalid because: services.pas.parsemicroservice.build.context contains null, which is an invalid type, it should be a string.

这是我的docker-compose.yml文件:

Here's my docker-compose.yml file:

version: '2.1'

services:
  pas.parsemicroservice:
    image: pas.parsemicroservice
    build:
      context: 
      dockerfile: Dockerfile

如果我在上下文中添加.(因为该错误暗示null存在问题)，则会收到另一个错误:

If I add a . to context (as the error implies the null there is the problem), I get a different error:

目标依存关系图中存在循环依存关系 涉及目标"DockerCleanServiceReferences".

There is a circular dependency in the target dependency graph involving target "DockerCleanServiceReferences".

全部是由于使用了错误的.NET框架导致的，还是我的文件设置有误? (可以肯定地说，我是Docker n00b.)

Is this all a result of using the wrong .NET framework, or are my files set up wrong? (I am a Docker n00b to be sure.)

推荐答案

更新:关于循环依赖问题，请确保您的SLN和CSPROJ文件不在同一文件夹中.这意味着，当您首次创建解决方案时，请确保选中为解决方案创建目录"框.

Update: Regarding your circular dependency issue, make sure your SLN and CSPROJ files are not in the same folder. Meaning that when you first create a solution, make sure to check the box that says "create directory for solution".

VS 2017绝对支持Docker对非.Net Core应用程序的支持，如该视频的9:15标记所示

Docker support for non .Net Core applications is definitely supported in VS 2017 as shown at the 9:15 mark of this video https://channel9.msdn.com/Events/Visual-Studio/Visual-Studio-2017-Launch/T111

您的context应指向Dockerfile所在的目录.此路径应相对于docker-compose.yml文件所在的位置.

Your context should point to the directory where your Dockerfile exists. This path should be relative to where your docker-compose.yml file is located.

撰写文件版本2参考: https://docs.docker.com/compose/compose-file/compose-file-v2/#context

Compose file version 2 Reference: https://docs.docker.com/compose/compose-file/compose-file-v2/#context
