制作redis镜像

FROM nginx-web1:v1

ADD redis-4.0.14.tar.gz /usr/local/src
RUN ln -sv /usr/local/src/redis-4.0.14 /usr/local/redis && cd /usr/local/redis && make && cp src/redis-cli /usr/sbin/ && cp src/redis-server  /usr/sbin/ && mkdir -pv /data/redis-data
ADD redis.conf /usr/local/redis/redis.conf
ADD run_redis.sh /usr/local/redis/run_redis.sh

EXPOSE 6379

CMD ["/usr/local/redis/run_redis.sh"]

 查看启动脚本

/usr/sbin/redis-server /usr/local/redis/redis.conf

tail -f  /etc/hosts   //守护进程

 为了包装redis数据完整，rdb、aof、session等信息需要被持久化。
