I’m playing around with Docker and trying to learn it. My goal is to create a micro-service setup with multiple .net core API’s and an Angular frontend.

I’ve started with 1 API.
I made a dockerfile and a docker-compose file.

my 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 ["Api/Api.csproj", "Api/"]
RUN dotnet restore "./Api/./Api.csproj"
COPY . .
WORKDIR "/src/Api"
RUN dotnet build "./Api.csproj" -c $BUILD_CONFIGURATION -o /app/build

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

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

My docker-compose file:

version: '3.4'

services:
  todo.api:
    image: todoapi
    container_name: todo.api
    build:
      context: ./TestProject.Service.Todo
      dockerfile: Api/Dockerfile
    ports:
      - "5000:5000"
      - "5001:5001"

Whenever I start the docker-compose it runs and creates a container without issue but when I try to access the “WeatherForecast” api method that is added by default in the API project I can’t access it.

When I run Visual Studio with the Docker option it also creates the container without issue and I can access the “WeatherForecast” api method without issues.

I currently can’t see what is wrong with my current basic setup, could someone help me out with spotting the issue?

I googled the issue but didn’t seem to find a working solution to my issue.
