If you want to follow this step-by-step. Please install some tools that will be required here.

  1. .NET 6: https://dotnet.microsoft.com/download/dotnet/6.0
  2. Docker: https://docs.docker.com/get-docker/

Project Preparation

  • Create the Web API from template.
dotnet new webapi -o DockerNetExample
Enter fullscreen mode Exit fullscreen mode
  • Create the solution to link the project and link the project.
dotnet new sln
Enter fullscreen mode Exit fullscreen mode

  • Create your Dockerfile at the root, similar place with the .sln file.
FROM mcr.microsoft.com/dotnet/sdk:6.0-alpine as build
WORKDIR /app
COPY . .
RUN dotnet restore
RUN dotnet publish -o /app/published-app

FROM mcr.microsoft.com/dotnet/aspnet:6.0-alpine as runtime

ENTRYPOINT [ "dotnet", "/app/DockerNetExample.dll" ]

  • Check your container. docker ps. You would see like this.

I have a suggestion so that the same does not happen to another:
This command: dotnet sln add DocketNetExample
Has an incorrect project name. It should be dotnet sln add DockerNetExample
It took me more than 5 minutes to realize haha

Thank you for the tutorial!
