1. redis官网：https://redis.io
   redis docker官网：https://hub.docker.com/_/redis/
2. 编写Dockerfile文件

COPY redis.conf /data/redis.conf
RUN chown redis:redis -R /data

WORKDIR /data

EXPOSE 6379

ENTRYPOINT redis-server /data/redis.conf

1. 构建成镜像
   docker build -t menard/alpine-redis:4.0.14 .
   
2. 编写docker-compose.yml文件

version: '2'
services:
redis:
image: "menard/alpine-redis:4.0.14"
hostname: redis
container_name: redis
ports:

environment:
- TZ=Asia/Shanghai
restart: always
#command: "redis-server /data/redis.conf"

1. cd /workspace/redis/ ，vim redis.conf编辑文件后修改权限，chown 100:101 redis.conf

1. docker-compose up启动容器，发现启动后容器又关掉了，查看日志无报错。
   
2. 把配置文件redis.conf的daemonize yes注释掉，这个是开启守护进程的，容器不能用这个。
3. 重新启动后无报错。
