docker-compose 搭建伪分布模式redis cluster集群

1、redis配置文件:redis.conf

port 6379
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes

2、创建文件和目录

for port in `seq 7001 7006`; do \
  mkdir -p ./${port}/conf \
  && PORT=${port} envsubst < ./redis-conf.tmpl > ./${port}/conf/redis.conf \
  && mkdir -p ./${port}/data; \
done

├── 7001
│   ├── conf
│   │   └── redis.conf
│   └── data
│       ├── appendonly.aof
│       ├── dump.rdb
│       └── nodes.conf ..........

3、docker-compose.yml文件
