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.

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.

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.

Answer 1

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 .

Answer 2

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

Answer 3

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.

Answer 4

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

Answer 5

you must put your Ip by ipconfig instead of localhost

Answer 6

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
