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

特别注意点：最后三个文件文件编码格式-UTF-8,换行编码-LF(UNIX)

1.2 docker-compose.yaml

networks:

  redisnet:
    driver: bridge
    ipam:
      config:

1.3 配套文件Dockerfile

FROM redis:6.0.9

MAINTAINER Lu Dongsheng <learning1567@hotmail.com>

RUN ln -sf /usr/share/zoneinfo/Asia/Tokyo /etc/localtime
RUN echo 'Asia/Tokyo' >/etc/timezone

# Dependent tool installation
RUN apt-get update
RUN apt-get install -y gettext-base && apt-get install -y apt-utils

COPY redis.conf /etc/redis/redis.conf.template
COPY start.sh /start.sh

ENTRYPOINT [ "/bin/bash", "/start.sh" ]

1.4 配套文件redis.conf

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

1.5 配套文件start.sh

envsubst '$X_REDIS_PORT:$X_REDIS_PORT' < /etc/redis/redis.conf.template > /etc/redis/redis.conf
redis-server /etc/redis/redis.conf

2. 部署

2.2 查看容器

$ docker ps

2.3 日志

为了更好地了解如何创建群集，请检查其中一个容器日志。

$ docker logs docker-redis-cluster_redis-1_1
$ docker logs docker-redis-cluster_redis-2_1
$ docker logs docker-redis-cluster_redis-3_1
$ docker logs docker-redis-cluster_redis-4_1
$ docker logs docker-redis-cluster_redis-5_1
$ docker logs docker-redis-cluster_redis-6_1

2.4 连接到Master其中之一
