[QUESTION] Docker - There's no dump.rdb in /var/lib/redis even after running redis-cli SAVE or BGSAVE

[Alya Gomaa]

I'm running an ubuntu image in docker and i installed redis as a service

Here's how i start redis in the Dockerfile:

CMD redis-server --daemonize yes && /bin/bash

now whenever i make changes to the database and run

redis-cli SAVE or redis-cli BGSAVE

 i expect to find a dump.rdb file generated in /var/lib/redis but that doesn't happen

these two lines are from my redis.conf in docker:

dbfilename dump.rdb

dir /var/lib/redis

 I don't want to mount my local dump.rdb file to the docker container.

How do i get redis to generate dump.rdb in docker?
