Helm Chart for Redis in Cluster Mode

⚠️ WARNING: Here be dragons

This code is extremely early alpha. Use at your own peril.

This is a helm chart that spins up a redis cluster with the associated stateful sets with the right settings in redis.conf. It supports the creation of a cluster with just masters or with slaves as well and provides the command to configure the cluster using redis_trib.rb.

Eventually the goal is for it to provide several other potentially useful operations:

• Gracefully terminating and cleaning up associated resources (read, deleting the persistent volumes it created)
• Increase cluster size
• Reduce cluster size
• Reshard keys (in relation to increasing and reducing cluster size)

TODO

• Execute the redis_trib.rb command presented at the end of the Helm chart automatically (probably by using a custom docker with the relevant packages installed)
• Move the Redis cluster container base image out into a public repository
