Fails to connect to redis, when running inside of docker container

Hey, the library works like a charm, thanks a lot. My application is a microservice, which connects to a redis database, which is running inside of docker. However, I can not connect to redis, when my application is running inside of container. I can still connect to redis remotely via cli on other host and it clearly works. I can also run my application outside of docker (directly on my host machine) and it would still connect. But when I build and run the image, it says:

[ioredis] Unhandled error event: Error: connect ECONNREFUSED 127.0.0.1:6379
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1085:14)

I also tried to provision my application to docker swarm with compose file on the same network as redis

version: "3"
services:
  myapp:
    image: user/app:latest
    deploy:
      restart_policy:
        condition: on-failure
    ports:
      - "5000:5000"
    networks:
      - webnet

  redis:
    image: redis
    ports:
      - "6379:6379"
    volumes:
      - "./data:/data"
    command: redis-server --appendonly yes
    networks:
      - webnet
      
networks:
  webnet:

But it still wouldn’t connect

Here is the code, I use in my application:

const redis = require('ioredis')
const appdb = new redis()

module.exports = { db }

Thank you in advance.

@MishUshakov Try delete the networks and replace redis section by:

redis:
    image: redis:latest
    command: ["redis-server", "--bind", "redis", "--port", "6379"]

That works for me.

Have you tried connecting to Redis via host “redis” (see https://docs.docker.com/compose/networking/)?

const redis = require('ioredis')
const appdb = new redis({host: 'redis'})

module.exports = { db }
