Redis Cache Setup

Overview

Redis serves as a critical component for:

• Session management
• Real-time features
• Caching layer
• Performance optimization

Deployment Options

Managed Service (Recommended)

Cloud Provider Options

Redis Cloud

1. Create account at Redis Cloud
2. Create new subscription:
   • Fixed plan (minimum 1GB)
   • Choose region
   • Enable password protection
3. Create database with default settings

Digital Ocean Redis

1. Access Digital Ocean Console
2. Create Database > Redis
3. Configure:
   • Choose smallest plan
   • Select datacenter
   • Enable eviction policy

tip

Managed services provide:

• Automatic backups
• High availability
• Security patches
• Performance monitoring

Helm Chart

Bitnami Redis Chart

1. Add repository:

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update

2. Install Redis:

helm upgrade --install redis oci://registry-1.docker.io/bitnamicharts/redis \
  --namespace redis \
  --version 18.19.2 \
  --create-namespace \
  --set architecture=standalone \
  --set global.redis.password=your-secure-password

3. Wait for deployment:

kubectl -n redis get pods -w

caution

For production use:

• Configure proper resource limits
• Set up persistence
• Consider high availability setup

Requirements

Minimum Specifications

• Redis 6.0 or higher
• 1GB memory
• Network access from platform
• Password protection enabled

Recommended Features

• Persistence enabled
• Automatic backups
• Monitoring setup
• Eviction policies configured

Information Collection

Required Values for Platform Installation

• Redis hostname/endpoint
• Port number (default: 6379)
• Password
• TLS enabled/disabled

Example Configuration

redis:
  host: "your-redis-host"
  port: 6379
  password: "your-secure-password"
  tls: true  # Set to false for local development

Validation

Test your Redis connection:

# Using redis-cli
redis-cli -h your-redis-host -p 6379 -a your-password ping

# Expected response
PONG

Troubleshooting

Common issues and solutions:

1. Connection Failures

   • Verify credentials
   • Check network/firewall rules
   • Confirm TLS settings
   • Validate endpoint format

2. Performance Issues

   • Monitor memory usage
   • Check eviction policies
   • Review connection limits
   • Verify resource allocation

Next Steps

1. ✅ Set up Redis instance
2. ✅ Configure security settings
3. ➡️ Proceed to S3 Storage Setup
