Redis Setup & Testing

What

Redis is an open-source, in-memory data structure store often used as a database, cache, and message broker.

It supports various data structures like strings, hashes, lists, sets, and sorted sets

Keys

Replication: Supports master-slave replication, making it suitable for high-availability setups.
Pub/Sub Messaging: Allows message publishing and subscribing, making it useful for real-time messaging applications.

Setup

Redis Cloud https://redis.io/try-free
Redis on machine https://redis.io/docs/latest/operate/oss_and_stack/install/install-stack/ ** Docker

Docker compose file

version: '3'

services:
  redis:
    image: redis:latest
    container_name: my_redis
    ports:
      - "6379:6379"
    volumes:
      - redis_data:/data
    restart: unless-stopped

volumes:
  redis_data:

Run docker compose file

docker-compose up -d

Check status

docker ps -a

Connect

With the redis-cli command line tool

connect to Redis using the Redis CLI

(Redis CLI is part of the Redis package, so installing Redis will also install the CLI)

(Redis CLI is a powerful tool for working with Redis directly from the terminal)

docker exec -it redis_container redis-cli

https://redis.io/docs/latest/develop/connect/cli/

Use Redis Insight as a graphical user interface

Install Redis Insight (using browser)

(As of RedisInsight version 2.x, the default internal port has changed to 5540 instead of 8001)

version: '3.8'

services:
  redisinsight:
    image: redis/redisinsight:latest
    container_name: redisinsight
    ports:
      - "8080:5540"   # Map host port 8080 to container port 5540
    volumes:
      - redisinsight_data:/data   # Attach the volume to /data in the container
    restart: unless-stopped

volumes:
  redisinsight_data:

Add a New Redis Database in RedisInsight

Host: Enter host.docker.internal if you’re using Docker Desktop (for macOS or Windows), or localhost if using Docker on Linux.

Port: Enter 6379, which is the default Redis port.
