Question

我正在尝试为dotnet core 2创建一个开发Dockerfile。到目前为止我的内容如下：

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

如果我跑：

dotnet restore
dotnet watch run

从同一个文件夹中，一切似乎都运行得很好（观察者开始）。当我改为运行该docker文件（在docker-compose环境中）时，它一直在喊：

找不到匹配命令“dotnet-watch”
的可执行文件

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>

并且你可以看到包含臭名昭着的：

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

这通常是造成问题的原因。

如何让dotnet watch在docker上工作？

Answer 1

我只需dotnet restore ENTRYPOINT就像这样：

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
