The Dockerfile

We'll cover the following

In this lesson, we are going to discuss the Dockerfile that we uploaded in the previous lesson. This lesson will show you how to fulfill all the requirements and dependencies of your application if you will run it in a Docker container.

Dockerfile

So here goes the Dockerfile:

Press + to interact
FROM mcr.microsoft.com/dotnet/sdk

Base Image

Press + to interact
FROM mcr.microsoft.com/dotnet/sdk

This image is officially maintained by Microsoft which contains the .NET Core SDK which is comprised of three parts:

  • NET Core CLI
  • NET Core
  • ASP.NET Core

It provides everything you need to build and debug ASP.NET applications. This image is used for the development process (developing, building, and testing applications).

Copying Files into Docker environment

If our files are stored locally on our machine, we can copy them into the container using the COPY command. However, in our case, we will directly import the code into the SPA editor (more on this later). Hence, we can skip this step.

All other commands that are used to initialize and run the application need to be provided in Docker Job explained in the next lesson.
