asp.net - Dotnet Core 2 docker :找不到与命令 “dotnet-watch”匹配的可执行文件

Question

我正在尝试为dotnet core 2创建开发Dockerfile。到目前为止，我的工作是:

FROM microsoft/aspnetcore-build:2.0

VOLUME /app
WORKDIR /app
COPY . ./
ENV ASPNETCORE_SERVER.URLS http://*:5000
ENV ASPNETCORE_ENVIRONMENT Development
RUN dotnet restore
ENTRYPOINT dotnet watch run --configuration Debug

如果我运行:

dotnet restore
dotnet watch run

在同一个文件夹中，一切似乎都可以正常工作(观察程序启动)。当我改为在docker-compose环境中运行该docker文件时，它一直在喊:

No executable found matching command "dotnet-watch"

我的配置文件如下:

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <Folder Include="wwwroot\" />
  </ItemGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />
    <PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="2.0.0" />
    <PackageReference Include="Microsoft.AspNetCore.Cors" Version="2.0.0" />
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="2.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="2.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="2.0.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.0" />
    <PackageReference Include="Newtonsoft.Json" Version="10.0.3" />
    <PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="2.0.0" />
  </ItemGroup>
  <ItemGroup>
    <DotNetCliToolReference Include="Microsoft.DotNet.Watcher.Tools" Version="2.0.0" />
    <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.0" />
  </ItemGroup>
</Project>

如您所见，其中包含臭名昭著的内容:

<DotNetCliToolReference Include="Microsoft.DotNet.Watcher.Tools" Version="2.0.0" />

通常是导致问题的原因。

如何使 dotnet watch在docker上工作？

Answer 1

我只需要像这样在dotnet restore中添加ENTRYPOINT:

FROM microsoft/aspnetcore-build:2.0

VOLUME /app
WORKDIR /app
COPY . ./
ENV ASPNETCORE_SERVER.URLS http://*:5000
ENV ASPNETCORE_ENVIRONMENT Development
ENTRYPOINT dotnet restore && dotnet watch run --configuration Debug
