When I run docker compose up, the app instance is getting an error of

[ioredis] Unhandled error event: Error: connect ECONNREFUSED 127.0.0.1:6379

Here’s the docker-compose.yaml:

services:
  app:
    restart: always
    image: svelte-docker
    build:
      context: .
      dockerfile: Dockerfile
      target: run
    ports:
      - 5173:5173
    networks:
      - net-a
  cache:
    image: redis:alpine
    restart: always
    ports:
    - 6379:6379
    networks:
      - net-a
networks:
  net-a:
    driver: bridge

Within the app I’m using the generic protocol connector:

const redis = new Redis({
    url: 'redis://redis:6379'
});

If I run the app outside of docker, with a running redis instance inside docker, they talk to each other just fine. But when I try to put both inside a compose file, they can’t.

What am I doing wrong here?
