Answer 1

It is an old question but I have a solution that seems elegant and I don't have to execute commands every time ;).

1 Create your dockerfile like this

#/bin/redis/Dockerfile
FROM redis
CMD ["redis-server", "--include /usr/local/etc/redis/redis.conf"]

What we are doing is telling the server to include that file in the Redis configuration. The settings you type there will override the default Redis have.

2 Create your docker-compose

redisall:
      build:
        context: ./bin/redis
      container_name: 'redisAll'
      restart: unless-stopped
      ports:
        - "6379:6379"
      volumes:
        - ./config/redis:/usr/local/etc/redis

3 Create your configuration file it has to be called the same as Dockerfile

//config/redis/redis.conf
requirepass some-long-password
appendonly yes

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only into
# the IPv4 loopback interface address (this means Redis will be able to
# accept connections only from clients running into the same computer it
# is running).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.*
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 127.0.0.1

 // and all configurations that can be specified
 // what you put here overwrites the default settings that have the
