Doctl command syntax to create kubernetes cluster. Copyable examples, output expectations, and common mistakes.

Terminal

doctl k c c --count <3> --region <nyc1> --size <s-1vcpu-2gb> --version <latest> <cluster_name>

doctl k c c --count <3> --region <nyc1> --size <s-1vcpu-2gb> --version <latest> <cluster_name>

#!/bin/bash

# Create Kubernetes Cluster
doctl {{[k|kubernetes]}} {{[c|cluster]}} {{[c|create]}} --count {{3}} --region {{nyc1}} --size {{s-1vcpu-2gb}} --version {{latest}} {{cluster_name}}

import subprocess

# Create Kubernetes Cluster
# Make sure to replace <placeholders> with actual values
