Added the small feature loginService
- How it works
  - Endpoints -> AuthService -> DatabaseQueries->DATABASE
  - DATABASE -> DatabaseQueries->AuthService->Endpoint->frontend
- This is done to separate the different layers.
  - Entrypoint receives requests
  - AuthService should apply all logic
  - DatabaseQueries should only fetch data
Tested on my own computer Fedora 43 using curl
get container ip using this command

docker inspect -f
'{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}'
container_name_or_id

possible to create a user using endpoint

curl -X POST http://172.18.0.3:8080/auth/SignUp \
  -H "Content-Type: application/json" \
  -d '{
    "Username": "jag orkar inte",
    "Firstname": "Eric",
    "Lastname": "Grandinger",
    "Email": "eric@example.com",
    "Password": "Let me in"
  }'

possible to sign in using endpoint

 curl -X POST http://172.18.0.10:8080/auth/login \
  -H "Content-Type: application/json" \
  -d '{"Username": "jag orkar inte", "Password": "Let me in"}'
  }'

WINDOWS 11

I've maybe done something wrong but I get this when trying to sign up an account:

The error suggest that the problem is related to trying to login to the database scram-sha-256 postgresql. The code i wrote fetches the login cridentials from the .env file

  static string DbUser = Environment.GetEnvironmentVariable("DATABASE_USER");
  static string DbPassword = Environment.GetEnvironmentVariable("DATABASE_PASSWORD");
  string ConnectionString = $"Host=PostgreSQL;Port=5432;Database=users;Username={DbUser};Password={DbPassword}";

My .env file has the following structure

DATABASE_USER=[USER]
DATABASE_PASSWORD=[PASSWORD]

The structure the you recive back .

errorMessage	IsSuccess
errorMessage	False

Suggests that your reach the endpoint put.

Did @c24elipe run on Windows? Otherwise it would be good to have one more person try on a windows machine to see if it's just me or not. I have correct .env file and all but I can't seem to get it to work for some reason although everything looks clean.

@b24hugst, I used Arch Linux. That may be where problems stem...

This is long sorry

Windows 11

Theres an issue with the windows rebuild where the path to the dockerfile is wrong. Accessing the service from curl on powershell doesn't work unless port forwarding. Even when port forwarding I only get a proper response in "localhost:5011/". /auth/login and /auth/SignUp respond with 400 Bad Request.

Also worth noting is that curl by default in powershell is an alias for Invoke-WebRequest. You can remove this alias by running

Remove-Item alias:curl

in powershell. curl will then use the windows variant which is also bad but works.
Anyways the way to access loginService will be through endpoint. When executing the commands listed by Erik in the initial PR inside the entryPoint container everything works well. In order to execute commands in a container you can run

docker exec -it entryPoint /bin/sh

And heres how the response looks from the container:

I noticed that when signing up the same user twice, the service returns an error from what looks like postgres:

It doesn't show any user data but it exposes a constraint in the users table. We should probably introduce some error handling to give an empty http 500 error

Summa summarum

I think if you change the WindowsRebuild to build properly, everything will be fine. It works!! It's just windows thats stupid
