레디스 서버용

version: '3.7'
services:
    redis6001:
      image: redis:5.0.3
      container_name: redis6001
      hostname: redis6001
      labels:
        - "name=redis"
        - "mode=standalone"
      network_mode: host
      ports:
          - 6001:6001
      volumes:
          - /root/docker/redis-5.0.3/6001:/data
      command: redis-server /data/redis.conf

센티널용

    sentinel16001:
      image: redis:5.0.3
      container_name: sentinel16001
      hostname: sentinel16001
      labels:
        - "name=redis"
        - "mode=sentinel"
      network_mode: host
      ports:
        - 16001:16001
      volumes:
        - /root/docker/redis-5.0.3/16001:/data
      command: redis-sentinel /data/sentinel.conf

클러스터용

    redis7001:
      image: redis:5.0.3
      container_name: redis7001
      hostname: redis7001
      labels:
        - "name=redis"
        - "mode=cluster"
      network_mode: host
      ports:
        - 7001:7001
        - 17001:17001
      volumes:
        - /root/docker/redis-5.0.3/7001:/data
      command: redis-server /data/redis.conf

성능을 고려해서 network_mode: host를 선택했습니다.
Label을 지정하면 docker ps -f (filter) label=mode=standalone 처럼 standalone/sentinel/cluster 종류별로 조회할 수 있습니다.
컨테이너의 hostname을 지정했습니다. 이렇게 하면 쉘로 접속했을 때 hostname을 표시할 수 있습니다.

# docker exec -it redis6001 /bin/bash
[root@redis6001 data]# hostname
 redis6001

시작하기

# docker-compose up -d redis6001
# docker-compose up -d sentinel16001
# docker-compose up -d redis7001

종료하기

# docker-compose stop redis6001
# docker-compose stop sentinel16001
# docker-compose stop redis7001

클러스터 생성

클러스터 생성 등 사용법은 일반 레디스와 동일하다.
IP는 호스트 IP를 사용한다.

# redis-cli --cluster create 192.168.56.103:7001 ... 192.168.56.103:7006 --cluster-replicas 1
