Docker redis configuration file redis.conf failed to start

  docker, question

Use docker to build reids to specify the configuration file. If you use docker run to set it, the configuration file redis.conf is valid:

docker run -d -ti \
 -p 6379:6379 \
 -v /home/docker/redis/conf/redis.conf:/etc/redis/redis.conf \
 --restart always \
 --name pos_redis \
 redis:3.0.6 \
 redis-server /etc/redis/redis.conf

However, the configuration file will not take effect in the way of docker-compose and dockerfile, and the default configuration file will be used automatically:
docker-compose.yml

version: "3"
 services:
 redis:
 container_name: redis_service
 build:
 context: ./redis
 dockerfile: Dockerfile
 ports:
 - "6379:6379"
 volumes:
 - /home/docker/redis/conf/redis.conf:/etc/redis/redis.conf
 networks:
 - "net1"
 networks:
 net1:
 driver: bridge

dockerfile

FROM redis:3.0.6
 ENV TIME_ZONE Asia/Shanghai
 RUN usermod -u 1000 www-data \
 && apk add --no-cache tzdata \
 && echo "${TIME_ZONE}" > /etc/timezone \
 && ln -sf /usr/share/zoneinfo/${TIME_ZONE} /etc/localtime \
 && redis-server /etc/redis/redis.conf

What is the difference between the two ways of running commands?

Supplement, use
ENTRYPOINT redis-server /etc/redis/redis.conf
Nor will it be implemented

I think there is something wrong with your Dockerfile.
apkIt is a package management command under Alpine Linux, but not under AlpineusermodInstruction, so I guess you will report the error when your image is built, please check and put the error on it.
