Redis OTP Storage with Docker | Node.js + Redis + Docker + MySQL | VectorDB Backend – tutorial #3
Redis OTP Storage with Docker | Node.js + Redis + Docker + MySQL | VectorDB Backend – tutorial #3
In this 3rd backend episode of our full-stack RAG (Retrieval-Augmented Generation) Multi-Agent series, we’ll enhance our OTP-based authentication system by storing OTPs securely in Redis using Docker. This approach improves performance, adds expiry control, and keeps sensitive data out of your main database.

What is Redis?
Redis (Remote Dictionary Server) is an open-source, in-memory key-value data store used for caching, message brokering, session storage, and real-time data analytics.
What is Docker?
Docker is a platform that lets you package and run applications in containers — lightweight, portable, self-contained environments.
🐳 Install Redis Using Docker
Command:
docker run -d --name redis-stack -p 6379:6379 -p 8001:8001 redis/redis-stack:latest
💻 Redis CLI Commands
Access the Redis container shell
docker exec -it redis-otp bash
OR
docker exec -it redis-stack bash
Enter Redis CLI
redis-cli
Set OTP
set otp:9876543218 256158
Get OTP
get otp:9876543218
Set OTP with expiration (5 minutes)
set otp:9876543218 256158 EX 300
Check TTL (Time-To-Live)
ttl otp:9876543218
Delete Key
del otp:9876543218
List All Keys
keys *
Flush All Keys
flushall
