Simplify your ops-life by using the Cassandra Kubernetes Operator to run your cluster!
In this scenario, we'll learn how to:
- Create a Kubernetes cluster
- Install the Cassandra Kubernetes operator
- Create a single node cluster
- Create a keyspace and table with data in the cluster
- Scale up the Cassandra cluster to two nodes using Kubernetes
With Kubernetes and this operator, your Cassandra life just got a lot easier!
This scenario is also available on our datastax.com/dev site, where you can find many more resources to help you succeed with Apache Cassandra™.

In this scenario, we learned how to:

- Scale up the Cassandra cluster to two nodes using Kubernetes
We've only scratched the surface or the Cassandra Kubernetes operator in this scenario. You can use the operator for so many other things.

Deploying and maintaining a Cassandra cluster never looked easier!

Steps
DataStax Kubernetes Operator for Apache Cassandra™
Create a Kubernetes Cluster
In this step we'll create a Kubernetes cluster consisting of the master node and some worker nodes.
We'll use KinD
to create the Kubernetes cluster named cassandra-kub-cluster.
What is KinD
?
KinD
is Kubernetes running inside a Docker container.
As you know, most people use Kubernetes to manage systems of Docker containers.
So, KinD
is a Docker container that runs Kubernetes to manage other Docker containers - it's a bit recursive.
We use
KinD
so we can create a many-node Kubernetes cluster on a single machine.
KinD
is great because it's relatively light-weight, easy to install and easy to use.
We've already installed
KinD
for you.
For your reference, here are the commands we used to install KinD
.
curl -Lo ./kind https://github.com/kubernetes-sigs/kind/releases/download/v0.7.0/kind-$(uname)-amd64
chmod +x ./kind
mv ./kind /usr/local/bin/kind
kind create cluster --name cassandra-kub-cluster --config kind-config.yaml
You can check out the KinD
yaml file we used to create the Kubernetes cluster:
kind-config.yaml
Let's verify we created the Kubernetes cluster.
kind get clusters
Notice that when reporting the clusters, KinD
reports the name we used to create the cluster.
But, when you reference the cluster from kubectl
, you need to prepended kind- to the front of our cluster name (e.g., kind-cassandra-kub-cluster).
Finally, let's connect kubectl
to our newly created Kubernetes cluster.
kubectl cluster-info --context kind-cassandra-kub-cluster
