Creating an ASP.NET Core 1.1 VS2017 Docker application

This blog shows how to setup a basic ASP.NET Core 1.1 application using Visual studio 2017 and Docker.

This article from Swaminathan Vetri demonstates how to setup everything for an ASP.NET Core 1.0 application.

Now the application needs to be updated to ASP.NET Core 1.1. Open the csproj file and update the PackageReference and also the TargetFramework to the 1.1 packages and target. At present, there is no help when updating the packages, like the project.json file had, so you need to know exactly what packages to use when updating directly.

<Project ToolsVersion="15.0" Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp1.1</TargetFramework>
    <PreserveCompilationContext>true</PreserveCompilationContext>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.0" />
    <PackageReference Include="Microsoft.AspNetCore.Routing" Version="1.1.0" />
    <PackageReference Include="Microsoft.AspNetCore.Server.IISIntegration" Version="1.1.0" />
    <PackageReference Include="Microsoft.AspNetCore.Server.Kestrel" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.EnvironmentVariables" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.FileExtensions" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Logging" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Console" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Options.ConfigurationExtensions" Version="1.1.0" />
  </ItemGroup>
</Project>

Then update the docker-compose.ci.build.yml file. You need to select the required image which can be found on Docker Hub. The microsoft/aspnetcore-build:1.1.0-msbuild image is used here.

version: '2'

services:
  ci-build:
    image: microsoft/aspnetcore-build:1.1.0-msbuild
    volumes:
      - .:/src
    working_dir: /src
    command: /bin/bash -c "dotnet restore && dotnet publish -c Release -o ./bin/Release/PublishOutput"

Now update the DockerFile to target the 1.1.0 version.

FROM microsoft/aspnetcore:1.1.0
ARG source
WORKDIR /app
EXPOSE 80
COPY ${source:-bin/Release/PublishOutput} .
ENTRYPOINT ["dotnet", "AspNetCoreVS2017Docker.dll"]

Start the application using Docker. You can debug the application which is running inside Docker, all in Visual Studio 2017. Very neat.

Notes:

When setting up Docker, you need to share the C drive in Docker.
