Question

I want to create Redis cluster in my docker based environment, Any docker base image that supports replication and allow me to create cluster using docker-compose would be helpful.

Answer 1

Here is my working .yml file

version: '3.7'

services:
  fix-redis-volume-ownership: # This service is to authorise redis-master with ownership permissions
    image: 'bitnami/redis:latest'
    user: root
    command: chown -R 1001:1001 /bitnami
    volumes:
      - ./data/redis:/bitnami
      - ./data/redis/conf/redis.conf:/opt/bitnami/redis/conf/redis.conf

  redis-master: # Setting up master node
    image: 'bitnami/redis:latest'
    ports:
      - '6329:6379' # Port 6329 will be exposed to handle connections from outside server 
    environment:
      - REDIS_REPLICATION_MODE=master # Assigning the node as a master
      - ALLOW_EMPTY_PASSWORD=yes # No password authentication required/ provide password if needed
    volumes:
      - ./data/redis:/bitnami # Redis master data volume
      - ./data/redis/conf/redis.conf:/opt/bitnami/redis/conf/redis.conf # Redis master configuration volume


  redis-replica: # Setting up slave node
    image: 'bitnami/redis:latest'
    ports:
      - '6379' # No port is exposed 
    depends_on:
      - redis-master # will only start after the master has booted completely
    environment:
      - REDIS_REPLICATION_MODE=slave # Assigning the node as slave
      - REDIS_MASTER_HOST=redis-master # Host for the slave node is the redis-master node
      - REDIS_MASTER_PORT_NUMBER=6379 # Port number for local 
      - ALLOW_EMPTY_PASSWORD=yes # No password required to connect to node
