[Question] - Why have the --cap-add sys_resource and --privileged to run the cluster locally?

First I want to say thanks for releasing this. I had a couple questions around why the cap add and privileged is required to run the redis docker cluster?

docker exec -d --privileged $rp_container_name_prefix "/opt/redislabs/bin/rladmin" cluster create name $rp_fqdn username $rp_admin_account_name password $rp_admin_account_password flash_enabled

docker run -d --cap-add sys_resource --name rp -p 8443:8443 -p 12000:12000 redislabs/redis

1. Examining the test code:

https://github.com/RedisLabs/DockerHub/blob/master/utils/test_repo.sh#L42
https://github.com/RedisLabs/DockerHub/blob/master/utils/test_repo.sh#L76

2. Docker details:
   https://docs.docker.com/engine/reference/run/#runtime-privilege-and-linux-capabilities

When the operator executes docker run --privileged, Docker will enable to access to all devices on the host as well as set some configuration in AppArmor or SELinux to allow the container nearly all the same access to the host as processes running outside containers on the host. Additional information about running with --privileged is available on the Docker Blog.

SYS_RESOURCE - Override resource Limits.

3. Are there specific resources the cluster needs that can be used with a combination of these constraints that make it clear what resources are recommended/required?

Kubernetes

Official redis and redis-ha charts are based on third party images.
Could be useful if these could rely on official redis docker images.
