docker下的redis哨兵集群环境搭建

1，redis的dockerfile编写

#redis专用dockerfile

FROM      centos:7.2.1511
MAINTAINER zzli

ENV REFRESHED_AT 2017-12-19

ENV REDIS_HOME /opt/redis/redis
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

ADD redis-3.2.9.tar.gz /opt/redis/
RUN ln -s /opt/redis/redis-3.2.9 $REDIS_HOME

RUN yum -y install gcc make
RUN mkdir -p /etc/redis/

WORKDIR $REDIS_HOME
RUN make && make install


EXPOSE 6379
EXPOSE 26379

ADD redis.sh /usr/local/bin/
RUN chmod +x /usr/local/bin/redis.sh
ENTRYPOINT ["/usr/local/bin/redis.sh"]

提交镜像
docker build . -t phj/redis:0.1

2,redis-sentinel的dockerfile编写

#redis专用dockerfile

FROM      centos:7.2.1511
MAINTAINER zzli

ENV REFRESHED_AT 2017-12-19

ENV REDIS_HOME /opt/redis/redis
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

ADD redis-3.2.9.tar.gz /opt/redis/
RUN ln -s /opt/redis/redis-3.2.9 $REDIS_HOME

RUN yum -y install gcc make
RUN mkdir -p /etc/redis/

WORKDIR $REDIS_HOME
RUN make && make install

EXPOSE 26379



ENTRYPOINT ["/usr/local/bin/redis-sentinel", "/etc/redis/sentinel.conf"]

提交镜像
docker build . -t phj/redis-sentinel:0.1

3，编写docker-compose启动redis集群

master1:
  image: phj/redis:0.2
  environment:
    HOSTNAME: redis-master
  container_name: redis1
  ports:
            - "6379:6379"
  volumes:
      - /redis/conf/master/:/etc/redis/
slave1:
  image: phj/redis:0.2
  environment:
    HOSTNAME: redis-slave
  ports:
            - "6380:6379"
  container_name: redis2
  volumes:
      - /redis/conf/slave/:/etc/redis/
  links:
      - master1:redis-master
sentinel1:
  image: phj/redis-sentinel:0.1
  expose:
        - 26379
  links:
    - master1:redis-master
    - slave1:redis-slave
  environment:
    HOSTNAME: redis-sentinel
  container_name: redis-sentinel
  volumes:
        - /redis/conf/sentinel/:/etc/redis/

** 4，启动docker-compose**

docker up -d

5，redis.sh脚本如下：

#!/bin/bash

/usr/local/bin/redis-server /etc/redis/redis.conf
/usr/local/bin/redis-sentinel /etc/redis/sentinel.conf
