Two Api connection via docker-compose and docker registry - docker

Question

We have one API project with DockerFile
FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 43001
EXPOSE 43002
FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src
COPY Api.csproj Api/
RUN dotnet restore Api/Api.csproj
COPY . .
WORKDIR /src/Api
RUN dotnet build Api.csproj --no-restore -c Release -o /app
FROM build AS publish
WORKDIR /src/Api
RUN dotnet publish Api.csproj --no-restore --no-self-contained -c Release -o /app
FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "Api.dll"]
And with docker-compose
version: '3.5'
services:
Api:
image: Api
restart: always
environment:
- ASPNETCORE_URLS=https://+:443;http://+:80
- ASPNETCORE_ENVIRONMENT=Production
build:
context: .
dockerfile: Api/Dockerfile
ports:
- "43001:80"
- "43002:443"
This project pushed to private docker registry.
And we have second Prod project that should use and connect to Api project.
docker-compose Prod project:
version: '3.5'
services:
Prod:
image: Prod
restart: always
environment:
- ASPNETCORE_ENVIRONMENT=Production
- ASPNETCORE_URLS=http://+:80
build:
context: .
dockerfile: Prod/Dockerfile
depends_on:
- Api
networks:
- proxy-net
expose:
- "80"
Api:
image: {RegistryAddress}/Api
restart: always
networks:
- proxy-net
ports:
- "43002:443"
networks:
proxy-net:
external:
name: proxy-net
Issue - When I am connecting from Prod to Api I am getting Connection refused. Perhaps something with ports settings, but I tried a lot of changes and it didn`t help. I thought Api ports settings should be enough, but looks like we need to set something in Prod also.
