DigitalOcean

This guide will show you how to provision a Digitalocean Database Cluster using Kubeform.

Examples used in this guide can be found here.

Look at the Terraform configuration below:

provider "digitalocean" {
    token = "DigitalOcean Token"
}

resource "digitalocean_database_cluster" "test1" {
    engine = "pg"

    name = "example-cluster"

    node_count" = 1

    region = "nyc1"

    size = "db-s-1vcpu-1gb"

    version = "11"
}⏎

This config creates a Digitalocean Database Cluster. We’ll create the exact configuration using Kubeform. The steps are given below:

1. Create CRD:

At first, create the CRD of Digitalocean Database Cluster using the following kubectl command:

$ kubectl apply -f https://github.com/kubeform/kubeform/raw/master/api/crds/digitalocean.kubeform.com_databaseclusters.yaml

2. Create DigitalOcean Provider Secret

Then create the secret which is necessary for provisioning the Database Cluster in Digitalocean.

apiVersion: v1
kind: Secret
metadata:
  name: do
type: "kubeform.com/digitalocean"
data:
  token: '<base64 encoded secret key>'

Here we can see that, the data of the secret is same as the field of the provider part in the terraform config file. Save it in a file (eg. secret.yaml) then apply it using kubectl.

$ kubectl apply -f secret.yaml

Note: here, data key (eg. token) must be in snake case format (same as the tf configuration file)

3. Create Digitalocean Database Cluster

Now, we’ll create the Digitalocean Database Cluster CRD. The yaml is given below:

apiVersion: digitalocean.kubeform.com/v1alpha1
kind: DatabaseCluster
metadata:
  name: test1
spec:
  name: example-cluster
  engine: pg
  version: "11"
  size: db-s-1vcpu-1gb
  region: nyc1
  nodeCount: 1
  providerRef:
    name: do

Here, we can see that the provider secret is referenced using a field called providerRef.

Save it in a file (eg. db_cluster.yaml) then apply it using kubectl.

$ kubectl apply -f db_cluster.yaml

After that, an Digitalocean Database Cluster will be created!

Delete Digitalocean Database Cluster

To delete the Digitalocean Database Cluster just run:

kubectl delete -f db_cluster.yaml
