Is it possible to upload blazor webassembly applications with . net core hosted on Herokuapp via Docker?

Question

When I go up a blazor server application, I use the following steps:

• I create a dockerfile file in the same folder where the project is so:

  FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base

  WORKDIR /app

  COPY . .

  CMD ASPNETCORE_URLS=http://*:$PORT dotnet NomeAplicativo.dll

I open cmd in the project folder and give the commands;

• dotnet publish -c release
• heroku container:login
• docker build -t {nome do aplicativo heroku} {caminho da pasta publish (com duas barras em vez de uma\\)}
• docker tag {nome do aplicativo heroku}
• docker tag {nome do aplicativo heroku} registry.heroku.com/{nome do aplicativo heroku}/web
• docker push registry.heroku.com/{nome do aplicativo heroku}/web
• heroku container:release web --app {nome do aplicativo heroku}

And that’s it! My app is running smoothly on Heroku. Just like this one http://selesgabriel.herokuapp.com

Before starting the steps, I copy the same Docker file to the folder where Publish is and only then start the Docker build

But when I try to do the same to blazor webassembly with . netcore hosted, does not work, by giving the command 'Docker run -p 8124:80 testeblazorapp' in cmd inside the Publish folder to see if the app is working normally, just like it happens on blazor server, it gives the following msg:

It was not possible to find any installed . NET Core Sdks Did you Mean to run . NET Core SDK Commands? Install a . NET Core SDK from: https://aka.ms/dotnet-download

I looked hard, but I couldn’t find anything. And when opening the Heroku app appears that msg as if it had no website on it, and when I run the command 'Docker run -p 8124:80 testeblazorapp', it gives the msg as in the msg I put below.
