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

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.

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.

# Copyright (c) 1993-2009 Microsoft Corp.

# 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.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.

192.168.1.44 gateway.docker.internal
# To allow the same kube context to work on the host and the container:
127.0.0.1 kubernetes.docker.internal
# End of section
Solution

  • 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 .
