The redis image pulled directly has no configuration file. You need to download the configuration file yourself. The download address of the configuration file is:http://download.redis.io/redis-stable/redis.conf. Mount the modified configuration file to the container. Then specify the configuration file when starting redis service.

$ $ docker run -it --name aley_redis -v /home/aley/data/redis.conf:/data/redis.conf -p 6379:6379 redis:latest /bin/bash
$ redis-server /data/redis.conf
