.NET 5 Core Web Application in Docker container

  .net-5, docker

I’m trying to run a .NET 5 web application in a Docker container locally with Docker Desktop (Windows containers).
The container runs but it won’t run in my browser. http://localhost:8080 or https://localhost:8001 doesn’t load properly.
I followed https://devblogs.microsoft.com/premier-developer/running-a-net-core-web-application-in-docker-container-using-docker-desktop-for-windows/.

This is what the Docker file looks like:

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src
COPY ["WebApplication1/WebApplication1.csproj", "WebApplication1/"]
RUN dotnet restore "WebApplication1/WebApplication1.csproj"
COPY . .
WORKDIR "/src/WebApplication1"
RUN dotnet build "WebApplication1.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "WebApplication1.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "WebApplication1.dll"]

I ran the container with

docker container run -d -p 8080:80 -p 8001:443 -e ASPNETCORE_HTTPS_PORT=8001 web-app:v1

Docker container logs show:

info: Microsoft.Hosting.Lifetime[0]
      Now listening on: http://[::]:80
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Production
info: Microsoft.Hosting.Lifetime[0]
      Content root path: C:app

What’s wrong here?
