DigitalOcean host provider released DigitalOcean Kubernetes which allows you to have a full k8s (Kubernetes) cluster in minutes with very few clicks.
The cool stuff here is that you’ll gonna pay only the worker nodes, not the masters. This means you can have a runnung cluster for $10/month with the smallest droplet they provide.
kubectl
kubectl is the command line tool to manage and use your k8s cluster.
You can install it on macOS using Homebrew :
1
$ brew install kubernetes-cli
Or by installing the Docker Desktop app.
DO K8s with kubectl
kubectl command line tool uses a config file in order to access the Kubernetes cluster.
This config file could be easily downloaded from the DigitalOcean UI.
Fetch the kubectl config file
Connect to the DO website and from the Kubernetes menu download the configuration file :
Install the config file
kubectl is reading the config from the ~/.kube/config file so just do the following :
1
2
$ mkdir ~/.kube
$ mv ~/Downloads/<cluster name>-kubeconfig.yaml ~/.kube/config
Check all is working fine
Now you want to check that all works fine so you try to get pods from your cluster :

$ kubectl get pods --all-namespaces=true

Now you need to go through the Kubernetes documentation in order to understand all the concepts and how to deploy and manage apps in Kubernetes.
For people, like me, wanting to preserve their eyes while reading the documentation, I did a dark theme for the Kubernetes webiste 😇.
