Redis with Sentinel
kube_redis_sentinel
This module deploys a highly-available set of Redis nodes.
This is deployed in a single master, many replica configuration. Failover is handled by Redis Sentinel which is also deployed by this module.
Extra Redis Configuration
You can add extra Redis configuration flags via the redis_flags module variable.
These flags are passed as commandline arguments to the redis servers. This ensures they will be of the highest precedence.
For more information about passing flags through the commandline and available options, see this documentation.
