docker-compose redis connection issue - node.js

Question

I have been trying to dockerize an api . But redis crashes. Nodejs and mongodb work.
Docker-compose.yaml file
version: '3'
services:
mongo:
container_name: mongo
image: mongo
networks:
- webnet
ports:
- '27017:27017'
redis:
image: redis
container_name: redis
command: ["redis-server","--bind","redis","--port","6379"]
ports:
- '6379:6379'
hostname: redis
app:
container_name: password-manager-docker
restart: always
build: .
networks:
- webnet
ports:
- '80:5000'
links:
- mongo
- redis
environment:
MONGODB_URI: ${MONGODB_URI}
clientID: ${clientID}
clientSecret : ${clientSecret}
PORT: ${PORT}
NODE_ENV : ${NODE_ENV}
JWT_SECRET_KEY: ${JWT_SECRET_KEY}
JWT_EXPIRE: ${JWT_EXPIRE}
REFRESH_TOKEN: ${REFRESH_TOKEN}
JWT_REFRESH_SECRET_KEY: ${JWT_REFRESH_SECRET_KEY}
JWT_REFRESH_EXPIRE: ${JWT_REFRESH_EXPIRE}
JWT_COOKIE: ${JWT_COOKIE}
networks:
webnet:
Docker file
FROM node:latest
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 5000
CMD ["npm","start"]
The error is Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379.
How can I fix this ?

Answer 1

by default all containers in a compose file will join a default network where they can communicate with each other, but if you specify a network then you have to specify it for all. So you can either remove the network declaration from the app and mongo services or specify it on the redis service.
