RedisInsight on Docker and Redis on Docker: Could not connect: Error 99 connecting to localhost:6379. Cannot assign requested address

Question

Based on this tutorial https://www.youtube.com/watch?v=XrFeRwJjWHI , I tried running Redis in Docker.

File docker-compose.yml

version: "3.8"

services:
  redis:
    image: redis
    volumes:
      - ./data:/data
    ports:
      - 6379:6379

docker pull redis
docker-compose up
docker-compose up -d
docker container ls
telnet localhost 6379

Telnet, type PING then press Enter key (you will not see text), then see result: PONG. Type quit to exit.

(c) 2020 Microsoft Corporation. All rights reserved.

D:\docker>docker-compose stop redis
Stopping docker_redis_1 ... done

D:\docker>

See what is running

docker container ls

You will see, docker redis was stoped.

docker image prune -a
docker-compose up

Docker RedisInsight

docker run -v redisinsight:/db -p 8001:8001 redislabs/redisinsight:latest

Wait about 6 minutes (at internet speed at 22:30) for downloading, unzip, install, starting.

go to: http://localhost:8001/ (auto open web browser). Health check for RedisInsight http://localhost:8001/healthcheck/ is OK.

(I also noted at here https://donhuvy.github.io/redis/docker/2020/10/10/run-redis-on-docker.html )

How to connect RedisInsight with Redis without error?

Update: This is my host file, seemly have problem at here (IP 127.0.0.1 for Kubernetes, really I don't know about Kubernetes, I am learning it.), but I don't know how to fix.

Are these containers running in the same network? Try to list the networks and the containers to see if these are on the same network — Eitank, Oct 10 '20 at 16:56
you can do the following to list networks with docker: `docker network ls`. to check the network of your container you can do the following: `$ docker inspect c1 -f "{{json .NetworkSettings.Networks }}"` c1 == the name of the container. — Eitank, Oct 12 '20 at 13:46

Using this setup in docker-compose.yml

version: '3.7'

services:
  redis:
    image: 'redis:6.0.6'
    ports:
      - '127.0.0.1:6379:6379/tcp'
    volumes:
      - 'redis_data:/data:rw'
    healthcheck:
      test: redis-cli ping
      interval: 3s
      timeout: 5s
      retries: 5

  redisinsight:
    image: 'redislabs/redisinsight:latest'
    ports:
      - '127.0.0.1:8001:8001'

you can access redis via

RedisInsight are trying to connect to container's localhost. Try typing 127.0.0.1 into Host field.

If file host has been changed like the updated information in question, use 192.168.1.44 .

@DoNhuVy according to your hosts file the IP address you are looking for is: `192.168.1.44` – n0nvme Oct 10 '20 at 16:47

For your containers to access each other you should first connect them to same network.

docker network create redis
docker network connect redis elastic_diffie
docker network connect redis docker_redis_1

After that open RedisInsight UI and write docker_redis_1 to your Hostand keep the port same. You should be able to connect to your redis container.

Since you haven't mentioned any network for the containers, they are conneted to the default bridge network. learn more

To get container IP address

Type in your terminal

# Check container network IP address

docker container inspect -f "{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}" <container name>

Use the IP address in: http://localhost:8001/ (RedisInsight).

or

(Not Recommended) Type the IP address of your HOST machine will solve the problem

Use ipconfig or ifconfig based on your OS to get your IP

I'm a little late to this one, but you can just use the docker host loopback

host.docker.internal - this will resolve to the host ip
