Dockerfile编写redis-cluster镜像

1、编写Dockerfile文件

vim Dockerfile

FROM centos:7
RUN yum -y install gcc gcc-c++ wget make    #安装依赖
RUN wget -P /root http://download.redis.io/releases/redis-5.0.2.tar.gz    #下载redis源码包到指定目录，自己也>可以拉
RUN cd /root && tar zxf redis-5.0.2.tar.gz && cd redis-5.0.2 && make MALLOC=libc && make install   #编译redis
RUN cp /root/redis-5.0.2/redis.conf /etc/ && rm -rf /root/redis*       #移动redis配置
RUN sed -i 's/^bind 127.0.0.1/bind 0.0.0.0/' /etc/redis.conf      #修改redis配置
RUN sed -i 's/# cluster-enabled yes/cluster-enabled yes/' /etc/redis.conf && yum -y remove gcc gcc-c++ wget make && yum clean all
ENV REDIS_PORT 6379
RUN echo -e '#!/bin/bash\nsed -i "s/6379/$REDIS_PORT/g" /etc/redis.conf\nredis-server /etc/redis.conf'>/root/startup.sh
CMD sh /root/startup.sh

2、创建redis-cluster镜像

docker build -t redis-cluster .

3、查看镜像是否构建成功

docker images
