# Kluster

A example Kubernetes operator to create Kubernetes cluster on DigitalOcean.

Once the operator is running, and we create a Kluster K8S resource in a cluster, a DigitalOcean Kubernetes

cluster would be created with provided configuration.

This operator was written as part of one of my [YouTube playlist](https://www.youtube.com/watch?v=89PdRvRUcPU&list=PLh4KH3LtJvRTtFWz1WGlyDa7cKjj2Sns0).

Here is an example of the Kluster resource

```

apiVersion: viveksingh.dev/v1alpha1

kind: Kluster

metadata:

  name: kluster-0

spec:

  name: kluster-0

  region: "nyc1"

  version: "1.21.3-do.0"

  tokenSecret: "default/dosecret" # secret that has DigitalOcean token

  nodePools:

    - count: 3

      name: "dummy-nodepool"

      size: "s-2vcpu-2gb"

```

# Deploy on a Kubernetes cluster

Execute below command, from root of the repo

Create Kluster CRD

```

kubectl create -f manifests/viveksingh.dev_klusters.yaml

```

Create RBAC resources and deployment

```

kubectl create -f manifests/install/

```

# Create a secret with DigitalOcean token

To call DigitalOcean APIs we will have to create a secret with DigitalOcean token that

will be used in the Kluster CR that we create.

```

kubectl create secret generic dosecret --from-literal token=

```

# Create a kluster CR

Create the kluster resource to create a k8s cluster in DigitalOcean

```

kubectl create -f manifests/klusterone.yaml

```
