• if you check the Dockerfile you see that it uses the image mcr.microsoft.com/dotnet/core/sdk:3.1 as building environment. You can use the dotnet CLI to create applications. See: https://dotnet.microsoft.com/learn/dotnet/hello-world-tutorial/install
• The example webapplication was made as follows:
  • dotnet new webApp -o myWebApp --no-https
  • cd myWebApp
  • dotnet watch build
  • dotnet run
• After that I created a Dockerfile inside the myWebApp folder. See example: https://docs.docker.com/engine/examples/dotnetcore/
  • Be sure all folder and .dll references to the folder named by your application (in my case 'myWebApp') !!
  • It uses a command to output the buildfiles to a folder using:
  • dotnet publish -c Release -o out
• I used an example Covid-19 registration form as an example to make it look better. Original source: https://111.nhs.uk/.
• I changed the pages:
  • ./Pages/index.cshtml
  • ./Pages/Shared/_Layout.cshtml
• And added some resources:
  • ./wwwroot/index_files/

git clone https://github.com/looking4ward/nhs-cac-docker-dotnetwebapp.git

cd nhs-cac-docker-dotnetwebapp/

docker build -t aspnetapp:latest .

• Build from current directory (.) and name it aspnetapp:latest

docker run -d -p 5000:80 --name myWebApp aspnetapp:latest

• Expose to http port to external port (default: 5000). Assign myWebApp as name. Use -d for detach mode (e.g background, instead of interactive mode -i)

http://localhost:5000

docker inspect myWebApp

docker exec myWebApp tail ../etc/os-release

• For example: tail [file]) in container
