# Kubernetes on DigitalOcean
IMO, the easiest Kubernetes cloud provider to experiment with is [DigitalOcean](https://m.do.co/c/e33b78ad621b) (_this is a referral link_). I've included instructions below to start a basic cluster.

## Ingredients
1. [DigitalOcean](https://m.do.co/c/e33b78ad621b) (_yes, this is a referral link, making me some 💰_) account, either linked to a credit card or (_my preference for a trial_) topped up with $5 credit from PayPal.
## Preparation
### Create DigitalOcean Account
Create a project, and then from your project page, click **Manage** -> **Kubernetes (LTD)** in the left-hand panel:

Until DigitalOcean considers their Kubernetes offering to be "production ready", you'll need the additional step of clicking on **Enable Limited Access**:

The _Enable Limited Access_ button changes to read _Create a Kubernetes Cluster_ . Cleeeek it:

When prompted, choose some defaults for your first node pool (_your pool of "compute" resources for your cluster_), and give it a name. In more complex deployments, you can use this concept of "node pools" to run certain applications (_like an inconsequential nightly batch job_) on a particular class of compute instance (_such as cheap, preemptible instances_)

That's it! Have a sip of your 🍷, a bite of your :cheese:, and wait for your cluster to build. While you wait, follow the instructions to setup kubectl (if you don't already have it)
![Kubernetes on Digital Ocean Screenshot #5](/images/kubernetes-on-digitalocean-screenshot-5.png)
DigitalOcean will provide you with a "kubeconfig" file to use to access your cluster. It's at the bottom of the page (_illustrated below_), and easy to miss (_in my experience_).

## Release the kubectl!
Save your kubeconfig file somewhere, and test it our by running ```kubectl --kubeconfig=<PATH TO KUBECONFIG> get nodes```
Example output:
```
[davidy:~/Downloads] 130 % kubectl --kubeconfig=penguins-are-the-sexiest-geeks-kubeconfig.yaml get nodes
NAME STATUS ROLES AGE VERSION
festive-merkle-8n9e Ready <none> 20s v1.13.1
[davidy:~/Downloads] %
```
In the example above, my nodes were being deployed. Repeat the command to see your nodes spring into existence:
```
[davidy:~/Downloads] % kubectl --kubeconfig=penguins-are-the-sexiest-geeks-kubeconfig.yaml get nodes
NAME STATUS ROLES AGE VERSION
festive-merkle-8n96 Ready <none> 6s v1.13.1
festive-merkle-8n9e Ready <none> 34s v1.13.1
[davidy:~/Downloads] %
[davidy:~/Downloads] % kubectl --kubeconfig=penguins-are-the-sexiest-geeks-kubeconfig.yaml get nodes
NAME STATUS ROLES AGE VERSION
festive-merkle-8n96 Ready <none> 30s v1.13.1
festive-merkle-8n9a Ready <none> 17s v1.13.1
festive-merkle-8n9e Ready <none> 58s v1.13.1
[davidy:~/Downloads] %
```
