我看到这个问题首先想到的就是去docker hub搜官方的redis镜像.然后看了redis的Dockerfile。官方的方法是（对应楼上的1）
Additionally, If you want to use your own redis.conf ...
You can create your own Dockerfile that adds a redis.conf from the context into /data/, like so
FROM redis
COPY redis.conf /usr/local/etc/redis/redis.conf
CMD [ "redis-server", "/usr/local/etc/redis/redis.conf" ]
或者
$ docker run -v /myredis/conf/redis.conf:/usr/local/etc/redis/redis.conf --name myredis redis redis-server /usr/local/etc/redis/redis.conf
这个镜像启动的时候就默认运行redis-server了。无法通过docker run -it redis修改。试图docker run -it redis /bin/bash进去覆盖默认的启动命令然后添加自己的配置就好了。
希望能帮到你
