.NET 7 + Docker

My previous post was about .NET 6 and Docker. Let's move on to .NET 7 and learn together.

Preparation

1. Docker
2. .NET 7 SDK

Starter Project

You can try cloning from the net6.0 branch from this repository.

Our Changes from Previous Repository

1. Add package Microsoft.NET.Build.Containers. You can use this command: dotnet add DockerNetExample package Microsoft.NET.Build.Containers.

2. Update DockerNetExample/DockerNetExample.csproj. We update the TargetFramework to net7.0 and add ContainerImageName.
   

   <Project Sdk="Microsoft.NET.Sdk.Web">
   
     <PropertyGroup>
       +<TargetFramework>net7.0</TargetFramework>
       <Nullable>enable</Nullable>
       <ImplicitUsings>enable</ImplicitUsings>
       <ContainerImageName>docker-net-example</ContainerImageName>
     </PropertyGroup>
   
     <ItemGroup>
       <PackageReference Include="Microsoft.NET.Build.Containers" Version="0.2.7" />
       <PackageReference Include="Swashbuckle.AspNetCore" Version="6.4.0" />
     </ItemGroup>
   
   </Project>
   

3. That's it! Our project is ready to create a docker image using dotnet publish. You can use this command: dotnet publish --os linux --arch x64 /t:PublishContainer -c Release.

   

4. Use this command (docker image ls) to check the docker image.

   

5. Let's run our container. Using this command: docker run --name docker-net-example -p 8080:80 -d docker-net-example:1.0.0

   

6. Check our container. Using this command: docker ps.

   

7. Test our Web API. You can navigate to localhost:8080 using your favorite browser, for example, I use Firefox.
