Redis doesn't connect with other image in docker

[Adewambe Daniel]

Hello, so i'm trying to run redis side by side a NestJS API, dockerize it and run it in an AWS instance
I tested it locally with my redis and local system, it works fine
But whenever i run my docker-compose up, i get the ERRCONFUSED error 127.0.0.1:6379
But if i run the nestjs container outside docker, it connects to the dockerized redis
Here is my docker-compose file

version: '3.3'
services:
  redis: # Name of container
    image: redis:6.2-alpine
    command: ["redis-server", "--bind", "0.0.0.0", "--port", "6379"]
    container_name: redis
    restart: unless-stopped
    network_mode: nebula
    expose:
      - 6379
    ports:
      - 6379:6379
  prod:
    container_name: ad-promoter-api-new-d
    image: ad-promoter-redis-prod-new-d:1.0.0
    build:
      context: .
      dockerfile: ./Dockerfile
      target: prod
    command: npm run start:prod
    ports:
      - 80:80
    network_mode: nebula
    links:
      - redis
    volumes:
      - .:/usr/src/app
      - /usr/src/app/node_modules
    restart: unless-stopped

Any help at all is appreciated
