Fails to connect to redis, when running inside of docker container #763

mishushakov · 2018-12-12T17:26:14Z

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.

The text was updated successfully, but these errors were encountered:

luin · 2018-12-12T17:34:31Z

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 }

mishushakov · 2018-12-12T17:38:36Z

Hey, @luin thanks for quick reply, I will try it and comment back in the issue in a second. Thank you

mishushakov · 2018-12-12T17:53:45Z

Still fails, but now with this error:

[ioredis] Unhandled error event: Error: getaddrinfo ENOTFOUND redis redis:6379
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:57:26)

luin · 2018-12-12T17:59:49Z

Will, that is a network problem and it should not be related to ioredis.

mishushakov · 2018-12-12T18:00:34Z

Ok, then I will try to hack around on my docker machine. Thank you

hendrixroa · 2019-01-03T02:22:45Z

@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.

aiyogg · 2019-09-06T16:22:20Z

Same problem for me, it's still exist I've tried all suggestions above. Who can help me to resolve this, please.

aiyogg · 2019-09-06T17:33:40Z

Same problem for me, it's still exist I've tried all suggestions above. Who can help me to resolve this, please.

It's ok after I run docker-compose build then docker-compose up.

Hey! How about running redis without docker-compose? I mean, running only the image. I lift the redis container using docker run --name redis.server -d -p 6379:6379 redis:latest but I can't connect from Sails (Node.js) using redis.server as hostname; the response is ENOTFOUND. The docker container is the official: https://hub.docker.com/_/redis/

Unfortunately did not work for me.
I deleted the docker networks. do i need to delete any other network, if any , please guide me.
i still have the error: [ioredis] Unhandled error event: Error: connect ECONNREFUSED 127.0.0.1:6379

Below is my docker-compose.yml file
version: '3'
services:
redis:
image: 'redis'
command: ["redis-server", "--bind", "redis", "--port", "6379"]
ports:
- "6379:6379"
networks:
- app-tier
apiserver:
build: .
ports:
- "7001:7000"
networks:
- app-tier
depends_on:
- redis
networks:
app-tier:
driver: bridge

below is my app.js
const Redis = require('ioredis');
const redis = new Redis();
I changed the above to const redis = new Redis({host: 'redis'}); but i still get the error

package.json file references to ioredis,
"ioredis": "^4.0.2",

armenr · 2019-12-07T00:23:34Z

I'm having a similar issue, and I've tried it a few different ways as suggested here.

codebanesr · 2019-12-07T09:26:06Z

Try using something like this, i dont see you using the port no to connect
to redis.
redis: new Redis({ port: 6379, host: process.env.REDIS_HOST, password: process.env.REDIS_PASS, })

in place of host you can simply use 'redis'
dont forget to provide the port number

shamim-42 · 2020-05-20T18:16:14Z

After couple of days of stuck today my project is running in your way. Thanks !

const client = redis.createClient({

Then rebuild ur docker with => docker-compose up --build

DrPep · 2020-11-22T22:52:39Z

For those who still have an issue here, my docker compose setup is/was configured with a bridged network setup. Adding Redis to the bridged network was required to allow it's network peers to connect:

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

networks:
  mynetwork:
    driver: bridge

Then connecting from my docker-hosted Node app with:

import redis from "ioredis"
const appdb = new redis({ host: "redis", port: 6379 })

If you want to then bind from the host machine, add in the requisite docker-compose port binding to the redis config block:

ports:
  - 6379:6379

HTH!

You saved my life too, spent many days to fix this nodejs code, and it looks like it was caused by the docker used in my QNAP container station.

redis:
image: redis:latest
container_name: devredisjs
restart: unless-stopped
environment:
NODE_ENV: development
PORT: 32700
ports:
- "32700:6379"
volumes:
- /share/Smart-Web/cache/redis:/data
command: ["redis-server", "--bind", "redis", "--port", "6379"]

houstondapaz · 2021-02-09T17:48:29Z

I fix this issue changing the redis.conf, by default it use 127.0.0.1, changing to 0.0.0.0 works like a charm
Just create an redis.conf file with this content:

# bind 127.0.0.1
bind 0.0.0.0

and send this file to container, using compose just link this volume

volumes:
  - /path/to/redis.conf:/tmp/redis.conf

AA25 · 2021-04-27T08:01:07Z

For others whose issue wasn't fixed by the above, this stackoverflow answer worked for me https://stackoverflow.com/a/58891367

If you're trying to connect from an app running in a container e.g. node app to redis running in a docker container, then the host string you set in your node app will need to be the name of your redis service name.

Following seems related: StackExchange/StackExchange.Redis#1002

cindyloo · 2022-02-09T15:15:06Z

inside my docker-compose.yml:

    image: redis:6.2
    restart: always
   
    ports:
      - "6379:6379"

and inside my code:

const redisClient = createClient({
   legacyMode:true
  });

// not sure if I need this or what this should be if we are in legacy mode. use host and port ???
//url: "redis://default:xxx@redis-15574.c17961xxx"

redisClient.on("error", (err) => console.log("Redis Client Error", err));

redisClient.connect();
...
store: new RedisStore({ client: redisClient }),

now I get

2022-02-09T14:57:36.816625+00:00 app[web.1]: Redis Client Error Error: connect ECONNREFUSED 127.0.0.1:6379

kmaramr · 2022-06-10T15:30:56Z

@cindyloo Were you able to resolve the connection issue? I have been having the same.

renatoam · 2022-06-17T21:20:50Z

I don't know why, neither if I'm doing something wrong, but what worked for me was put the same name to REDIS_HOST and the container_name, in compose file.

docker-compose.yaml

cache:
    image: redis
    restart: always
    command: redis-server --requirepass ${REDIS_PASSWORD}
    container_name: ${REDIS_HOST} # getting name from .env file

redis.ts

export const redis = new Redis({
  port: Number(process.env.REDIS_PORT) || 6379,
  host: process.env.REDIS_HOST, // getting the same name from .env file
  password: process.env.REDIS_PASSWORD
});

I just could notice that after @luin comment, so thanks fot that!

sbk2k1 · 2023-07-26T16:03:30Z

Update: 26 July 2023

My docker-compose looks like this

redis:
    image: redis:latest
    restart: always
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
    networks:
      - my-network
    ports:
      - 6379:6379

Passing the REDIS url through the Backend like this

environment:
      - ACCESS_TOKEN_SECRET=${ACCESS_TOKEN_SECRET}
      - JWT_SECRET=${JWT_SECRET}
      - PORT=${PORT}
      - MONGO_DB_URL=${MONGO_DB_URL}
      - API_INTERVAL=${API_INTERVAL}
      - REDIS_URL=${REDIS_URL}

.env looks like this

REDIS_URL='redis://redis:6379'

and using it in Node

var client = redis.createClient({url: process.env.REDIS_URL});
