基于 Docker 搭建 Redis 集群

1. 创建 network

   docker network create --driver bridge --subnet 172.22.0.0/16 --gateway 172.22.0.1  op_net

2. 创建 redis.yml

   version: '3.6'
   
   services:
     redis-1:
       image: redis
       restart: always
       hostname: redis-1
       container_name: redis-1
       ports:
         - 6379:6379
       networks:
         default:
           ipv4_address: 172.22.0.26
   
     redis-2:
       image: redis
       restart: always
       hostname: redis-2
       container_name: redis-2
       ports:
         - 6380:6379
       command: redis-server --slaveof redis-1 6379
       networks:
         default:
           ipv4_address: 172.22.0.27
   
     redis-3:
       image: redis
       restart: always
       hostname: redis-3
       container_name: redis-3
       ports:
         - 6381:6379
       command: redis-server --slaveof redis-1 6379
       networks:
         default:
           ipv4_address: 172.22.0.28
         
   networks:
     default:
       external:
         name: op_net

3. 启动 Redis 集群

   docker-compose -f redis.yml up -d
