Dockerizing a CSharp

So, A simple dockerfile would look something like this

FROM mcr.microsoft.com/dotnet/sdk:7.0

COPY . /app

WORKDIR /app

RUN \["dotnet", "restore"\]

RUN \["dotnet", "build"\]

ENTRYPOINT \["dotnet", "run"\]

Our base image is mcr.microsoft.com/dotnet/sdk:7.0 , which is the dotNet SDK.

Next we cope everything and put it into /app.

here's what the project folder structure looks like:

|-modulescmds

|-Program.cs

|-dockerfile

|-project.csproj

Afterward we set the work directory to /app (any command eg: the next line, will be run in this folder)

Next we run dotnet restore & dotnet run

Finally entrypoint is an alternative to the typical CMD, the differences are explained in this doc: https://www.docker.com/blog/docker-best-practices-choosing-between-run-cmd-and-entrypoint/

Finally we can build and run it like so

docker build -t imagename . 

docker run imagename
