Cant connect client to backend service through docker-compose `endpoints`

Help
1

Hi there,

I have a docker-compose.yml as follows with frontend and backend services.
I tried implementing the endpoints directive under the Docker compose docs.

version: '3.7'

services:
  backend:
    container_name: backend
    ...
    ports:
      - 4000
  postgres:
    image: postgis/postgis:14-3.3
    ...
    ports:
      - 5432:5432
    volumes:
      - pgdata:/var/lib/postgresql/data
  frontend:
    ...
    ports:
      - 3000
volumes:
  pgdata:
endpoints:
  - path: /
    service: frontend
    port: 3000
  - path: /api
    service: backend
    port: 4000

When deployed, 2 endpoints showed up (which was expected and correct)

  1. frontend - https://someurl.cloud.okteto.net
  2. backend - https://someurl.cloud.okteto.net/api

The issue was that the fetch request from the frontend using https://someurl.cloud.okteto.net/api coudn’t find the api endpoint. Resulting in the following error :
Failed to load resource: the server responded with a status of 404 (Not Found)

I suspect this is a k8s networking issue but Im not sure since I have almost zero experience with k8s (Thats why I love okteto ! :heart:)

Really appreciate any help/ advice on this !

Sincerely
Han
