This is reported in https://github.com/docker-library/redis/issues/87

The code calls resetServerSaveParams() after parsing the arguments and before loading the config file. @antirez - is that the intended behavior?

Can it be related to my issue. I tried to create a populated docker image of Redis, but files are removed after container is start up. Any ideas how to resolve it? How can I create a docker pre-populated docker image of Redis?
