Docker를 사용하여 Redis 클러스터(predixy)를 설정하는 구성하는 방법

구성도

r1

predixy, redis-cluster 컨테이너로 구성

git clone

git clone https://github.com/anti1346/predixy-redis-cluster.git

레디스 네트워크 생성

docker network create --gateway 172.24.0.1 --subnet 172.24.0.0/16 redis-net

docker-compose up

cd predixy-redis-cluster

docker-compose up -d

로그 출력

docker-compose logs -f
