Redis Sentinel

Quickly set up a Redis Sentinel using docker-compose for verification or testing environments.

mkdir /data/redis-sentinel
cd /data/redis-sentinel

vim docker-compose.yaml

docker compose up -d

Sentinel

config

Sentinel must use a configuration file when running, because the system will use this file to save the current state for reloading upon restart. If no configuration file is provided or the configuration file path is not writable, Sentinel will refuse to start.

mkdir config-2770{1,2,3}
