Introduction to Docker for .NET Developers

Why Docker?

Docker eliminates the "works on my machine" problem by packaging your app with all dependencies.

Creating a Dockerfile

FROM mcr.microsoft.com/dotnet/aspnet:10.0
WORKDIR /app
COPY ./publish .
ENTRYPOINT ["dotnet", "MyApp.dll"]

Building and Running

docker build -t myapp .
docker run -p 8080:80 myapp

Docker Compose

Manage multi-container apps easily:

version: '3.8'
services:
  web:
    build: .
    ports:
      - "8080:80"

Conclusion

Docker is essential for modern deployments. Start containerizing today!
