Dockerize your .NET Core project

As one of the .NET developers, traditionally we build and publish our code then host our web applications on IIS. Now, there's an alternative - Docker.

What's Docker?

You can find the answer at https://en.wikipedia.org/wiki/Docker_(software)


This post is going to introduce how to use Docker to create an image of a .NET Core webapi project. And later on, we are going to push this image to Docker Hub.

If you don't want to read the content but just want to find some source code sample you can go straight to get it here https://github.com/sskset/dockerize-dotnet-core.

Prerequisites:

• .NET Core SDK - Code
• https://dotnet.microsoft.com/download
• Visual Studio Code or Visual Studio
• https://code.visualstudio.com/
• Docker Desktop - Build a docker image
• https://www.docker.com/products/docker-desktop
• Docker Hub - Host the docker image
• https://hub.docker.com/

Create a .NET Core 2.2 webapi project

Open it in Visual Studio Code

Start it up

Open Browser to test it

Publish

Add Dockerfile

Docker build image

docker run -t sskset/dockerize-dotnet-core .

Push image to Docker Hub

Open hub.docker.com to view your image

As it's public, you can also view it by searching image name - sskset/dockerize-dotnet-core

Done

That's pretty much it. I'll introduce how to use it in next post.
