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

2. UpdateDockerNetExample/DockerNetExample.csproj. We update theTargetFrameworktonet7.0and addContainerImageName.

   <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 usingdotnet 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 tolocalhost:8080using your favorite browser, for example, I use Firefox.
