Cluster Docker Redis

Crie uma placa de rede

 docker network create netredis --subnet 172.38.0.0/16

Crie 6 configurações de redis por meio de scripts

Crie um cluster

Primeiro, basta inserir um contêiner redis e, em seguida, conduzir o cluster

docker exec -it redis-1  /bin/sh

 redis-cli --cluster create 172.38.0.11:6379  172.38.0.12:6379   172.38.0.13:6379   172.38.0.14:6379   172.38.0.15:6379   172.38.0.16:6379  --cluster-replicas 1
