[Redis] Docker에 Redis 설치하기

Redis는 In Memory Key, Value 데이터 구조의 데이터를 저장할 수 있는 비정형 데이터 베이스입니다.

메모리 DB 이기때문에 속도가 빠르고, 영속성 및 다양한 데이터 구조와 같은 부가적인 기능을 지원하고 있어서, Key-Value DB 중 가장 인기가 좋습니다.

? redis-net 이라는 Docker Network를 생성한다.
$>docker network create redis-net

? Docker Redis 컨테이너 생성
? -d : 백그라운드 실행
? -p : 포트 포딩 - 6379번 포트로 들어온 내용은 6379번 포트로 포딩을 해주겟다는 내용
? -v : host 와 연결할 폴더 지정
? --name Container 이름을 설정해줍니다. 
? docker exec -> run a command on an existing/running container
? docker run -> create a new container from an image, and run the command there
$>docker run --name redis_boot -p 6379:6379 --network redis-net -v redis_boot:/data -d redis redis-server --appendonly yes

? docker에 설치된 컨테이너 목록 조회
? -a, --all: 컨테이너 모두 보기: 멈춘 컨테이너도 보여줍니다.
$>docker ps -a
