Deploy CockroachDB in a DigitalOcean Kubernetes Cluster

For the DigitalOcean Kubernetes Challenge, I wanted to deploy a database to a managed Kubernetes cluster, and decided to go with CockroachDB Core.

The process to deploy on Kubernetes was simple. I just followed the instructions in CockroachDB official documentation, with just one change - In "Step 1. Start Kubernetes", instead of using hosted GKE or EKS (as mentioned in the docs), I used DigitalOcean's Managed Kubernetes service.

So my "Step 1. Start Kubernetes" was basically:

• How to Create Kubernetes Clusters Using the Control Panel from DigitalOcean. I created a 3 node cluster with s-4vcpu-8gb droplets. You should be able to do it with slightly smaller droplets too.

Rest of the steps were as mentioned in the doc:

• Step 2. Start CockroachDB
• Step 3. Use the built-in SQL client
• Step 4. Access the DB Console
• Step 5. Stop the cluster
