​
Overview

Redis functions as a critical performance layer in Linqra’s architecture, significantly reducing latency and database load. It provides real-time data processing and caching capabilities essential for high-performance API operations.

​
Local Development Setup

​
Docker Configuration

The Redis instance for local development is configured using Docker Compose and a custom Dockerfile.

​
Docker Compose Configuration

services:
  redis-service:
    build:
      context: .
      dockerfile: ./.kube/redis/Dockerfile
    environment:
      REDIS_GATEWAY_URL: redis-service
    ports:
      - "6379:6379"
    volumes:
      - ./.kube/redis/data/:/var/lib/redis/data
      - ./.kube/redis/redis.conf:/usr/local/etc/redis/redis.conf
    command: ["redis-server", "/usr/local/etc/redis/redis.conf"]
    networks:
      - linqra-network

​
Dockerfile

FROM redis/redis-stack:latest

​
Redis Configuration (redis.conf)

bind 0.0.0.0
protected-mode no
port 6379
  • bind 0.0.0.0 allows connections from any IP address
  • protected-mode no disables the protected mode (suitable for development)
  • port 6379 sets the default Redis port

​
Directory Structure

.kube/
└── redis/
    ├── Dockerfile
    ├── redis.conf
    └── data/

​
Connection Configuration

Redis connection settings can be configured through environment variables:

# Redis Connection Settings
export REDIS_HOST="localhost"
export REDIS_PORT="6379"
export REDIS_PASSWORD="your_password"

Redis is configured for high availability with appropriate persistence settings to prevent data loss during restarts.
