redis6.09 集群安装(docker-compose)

1. docker-Compose构成

1.1 docker-redis-cluster文件夹准备明细

序号目录或文件作用

1./docker-redis-cluster总配置目录

2./docker-redis-cluster/docker-compose.yaml部署文件

3./docker-redis-cluster/redis/Dockerfile镜像配置文件

4./docker-redis-cluster/redis/redis.confredis配置文件

5./docker-redis-cluster/redis/start.shredis启动脚本

1.2 docker-compose.yaml

1.3 配套文件Dockerfile

FROMredis:6.0.9MAINTAINERLu Dongsheng RUN ln -sf /usr/share/zoneinfo/Asia/Tokyo /etc/localtimeRUNecho'Asia/Tokyo'>/etc/timezone# Dependent tool installationRUN apt-get updateRUN apt-get install -y gettext-base && apt-get install -y apt-utilsCOPY redis.conf /etc/redis/redis.conf.templateCOPY start.sh /start.shENTRYPOINT["/bin/bash","/start.sh"]复制代码

1.4 配套文件redis.conf

port $X_REDIS_PORTcluster-enabled yescluster-config-file nodes.confcluster-node-timeout 5000appendonly yes复制代码

1.5 配套文件start.sh

envsubst'$X_REDIS_PORT:$X_REDIS_PORT'< /etc/redis/redis.conf.template > /etc/redis/redis.confredis-server /etc/redis/redis.conf复制代码
