I've enabled External traffic but still not working, missing something?

It tell that it only work if in enviroment the property internal is set to false. But i can't find that property

Answer 1

I created a ASP.NET Core Web API VS template and Deployed to Container apps.

This is my project structure:

Default Dockerfile:

#See https://aka.ms/customizecontainer to learn how to customize your debug container and how Visual Studio uses this Dockerfile to build your images for faster debugging.

FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base
USER app
WORKDIR /app
EXPOSE 8080
EXPOSE 8081

FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
ARG BUILD_CONFIGURATION=Release
WORKDIR /src
COPY ["WebApplication1/WebApplication1.csproj", "WebApplication1/"]
RUN dotnet restore "./WebApplication1/WebApplication1.csproj"
COPY . .
WORKDIR "/src/WebApplication1"
RUN dotnet build "./WebApplication1.csproj" -c $BUILD_CONFIGURATION -o /app/build

FROM build AS publish
ARG BUILD_CONFIGURATION=Release
RUN dotnet publish "./WebApplication1.csproj" -c $BUILD_CONFIGURATION -o /app/publish /p:UseAppHost=false

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

This is my configuration of the Container App.

OUTPUT:

It is throwing 404 error on the Url because API is not hosted on the home('/') path.

API is hosted on path /weatherforecast.

EDIT: Adding swagger file

To add swagger you need to add these code in you Program.cs swagger.SwaggerEndpoint("/swagger/v1/swagger.json", "Web API 1"); it will generate a swagger file based on the router/contoller/model used in project to render the swagger UI when web API is build.

app.Environment.IsProduction() is added for production environment like Azure or any other cloud services.

if (app.Environment.IsDevelopment()|| app.Environment.IsProduction())
{
    app.UseSwagger();
    app.UseSwaggerUI(swagger =>
    {
        swagger.SwaggerEndpoint("/swagger/v1/swagger.json", "Web API 1");
    });
}

It is accessible at path /swagger/index.html
