序
本文讲述一下如何docker话360开源的持久化的redis，即pika
dockerfile
FROM centos:7
RUN yum -y update
ADD pika-linux-x86_64-v2.2.6.tar.bz2 /opt
RUN mv /opt/pika-linux-x86_64-v2.2.6 /opt/pika-v2.2.6
ENV PIKA /opt/pika-v2.2.6
ENV PATH ${PIKA}/bin:${PATH}
WORKDIR ${PIKA}由于官方的Dockerfile没有指定centos版本，直接用latest，导致build起来有些问题，不同版本的类库有的仓库里头没有，相对费劲，另外直接make出来的版本目测又2+G，没研究怎么去瘦身，于是干脆还是用二进制的版本了
运行
docker run --name "PIKA" --rm -v /pika-data/db:/opt/pika-v2.2.6/db -p 9221:9221 pika:v2.2.6 pika -c /opt/pika-v2.2.6/conf/pika.conf测试
redis-cli -h localhost -p 9221
