Docker-compose로 Redis Cluster 자동 구성하기
이번 글에서는 docker-compose 로 redis-cluster를 구성해보겠습니다. 여기서 사용한 redis 이미지 및 redis / sentinel conf 파일 등 기본 환경은 제가 개인적으로 만든 것이기 때문에
이 글을 참고하시는 경우엔 본인의 환경에 맞게 설정이 필요합니다.
구성
* docker-compose.yml
* redis_cluster_1a
* Dockerfile
* docker-entrypoint.sh
* redis_cluster_2a
* redis_cluster_3a
* redis_cluster_1b
* redis_cluster_2b
* redis_cluster_3b
=> Master 3ea , Slave 3ea 생성
