RethinkDB on Kubernetes

Running a RethinkDB cluster on Kubernetes.

• Super simple - no configuration required
• Runs cluster as a StatefulSet which prevents data loss when the cluster unexpectedly shuts down
• Automatic peer discovery using the Kubernetes service

Quick Start

To create the RethinkDB cluster run this command:

kubectl create -f https://raw.githubusercontent.com/lucacasonato/rethinkdb-kubernetes/v2.4.0/cluster.yaml

This will set up all of the required Kubernetes resources. You can now use the command below to view if your node is ready:

kubectl get sts rethinkdb-nodes

Your cluster is now ready for operation!

Advanced usage

Scaling the cluster

To scale the cluster up and down run this command:

kubectl scale sts rethinkdb-nodes --replicas 3

Using the admin panel

To view the RethinkDB admin panel you need to forward the port it is listening on to your computer. You can do this from any of the running RethinkDB nodes in the stateful set.

kubectl port-forward rethinkdb-nodes-0 8080

You can now visit http://localhost:8080 to view the admin panel.
