Setup Redis with Docker Compose

For small size team, it’s better to setup Redis on a EC2 instance instead of AWS Elasticache. This is the pricing of Elasticache:

cache.t3.medium price: 720 * 0.068$ = 50$. If you have Multi AZ the data will be available in different zone multiplied with the price. Personally I think it’s expensive. Let’s host on EC2 with dirt cheap price:

Pre-requisites: Ubuntu 20.0 AMI (latest), docker + docker engine, t5-large instance. This is a an example of docker compose with redis + redis-insights.

docker-compose.yml


version: '3.9'

services:
  redis-stack:
    image: redis/redis-stack:latest # production image use redis/redis-stack-server only without redis-insights
    container_name: redis-stack
    restart: unless-stopped
    ports:
      - "6379:6379"
      - "8001:8001" # redis insights port
    volumes:
      - ./local-data:/data # mount local data volume
    environment:
      REDIS_ARGS: '--appendonly yes' # for development can use appendonly args to write AOF file on disk, we want redis to replay all the command when server/daemon restart

Profit!
