Deploy the cloudbeaver helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

Deploying a Helm chart to a Digital Ocean Kubernetes Service involves several steps. We'll approach it with Pulumi in TypeScript, which allows you to declare your infrastructure as code.

To set the stage, you'll need to start by creating a Kubernetes cluster in Digital Ocean. Once the cluster is ready, you'll need to configure Pulumi to deploy resources to this cluster. Lastly, you'll install the CloudBeaver Helm chart on this cluster.

We'll use two main resources from the Pulumi Registry:
1. `digitalocean.KubernetesCluster` - This resource will create a Kubernetes cluster in your DigitalOcean account. [Documentation](https://www.pulumi.com/registry/packages/digitalocean/api-docs/kubernetescluster/)
2. `kubernetes.helm.v3.Chart` - This resource from the Kubernetes provider will allow you to deploy Helm charts to the cluster. [Documentation](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/)

Here is the program that will accomplish your goal:

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as digitalocean from '@pulumi/digitalocean';
import * as k8s from '@pulumi/kubernetes';

// Create a Digital Ocean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster('do-cluster', {
    region: 'nyc1', // Choose the appropriate region for you
    version: 'latest', // Specify the version or use 'latest'
    nodePool: {
        name: 'default',
        size: 's-2vcpu-2gb', // This is the smallest size, select according to your needs
        nodeCount: 2, // Change this for more nodes
    },
});

// Create a provider for the created cluster
const kubeConfig = cluster.kubeConfigs[0].rawConfig;
const k8sProvider = new k8s.Provider('do-k8s', {
    kubeconfig: kubeConfig,
});

// Deploy the CloudBeaver Helm chart
const cloudBeaverChart = new k8s.helm.v3.Chart('cloudbeaver', {
    chart: 'cloudbeaver',
    version: '0.1.0', // Use the Helm chart version that you want to install
    fetchOpts: {
        repo: "http://helm-repo-url/", // Specify the Helm chart repository URL
    },
}, { provider: k8sProvider });

// Export the K8s cluster name and CloudBeaver endpoint
export const kubeClusterName = cluster.name;
export const cloudBeaverEndpoint = cloudBeaverChart.getResourceProperty('v1/Service', 'cloudbeaver', 'status').apply(status => status.loadBalancer.ingress[0].ip);
```

This program begins by importing the necessary Pulumi libraries for DigitalOcean (`@pulumi/digitalocean`) and Kubernetes (`@pulumi/kubernetes`).

### Creating the Kubernetes Cluster
- We create a `digitalocean.KubernetesCluster` instance with the desired configuration, such as region, Kubernetes version, and the size and number of nodes for the node pool.

### Provisioning Kubernetes Provider
- We extract the kubeconfig required to interact with the Kubernetes cluster, provided by DigitalOcean once the cluster is provisioned.
- The kubeconfig is passed to the Kubernetes provider (`k8s.Provider`), which will allow Pulumi to perform actions on the Kubernetes cluster.

### Deploying the CloudBeaver Helm Chart
- A `k8s.helm.v3.Chart` resource is declared with the name 'cloudbeaver', and the Helm chart version and repository URL are specified. This resource instructs Pulumi to deploy the CloudBeaver Helm chart to the cluster.
- It’s important to note that the `provider: k8sProvider` argument ensures this Helm chart is deployed on the DigitalOcean Kubernetes cluster that we've created.

### Outputs
- Finally, we've declared some export statements to output the name of the Kubernetes cluster and the endpoint for the deployed CloudBeaver service. This endpoint can be used to access your CloudBeaver instance once it's deployed.

Please replace placeholder values such as the Helm chart version and repository URL with the actual values based on the CloudBeaver Helm chart you intend to deploy. Also, make sure that you have the DigitalOcean provider and access token configured properly in your Pulumi setup.

Once you've set your configurations, you can run this program via the Pulumi CLI, which will execute the deployment as per the code. After running `pulumi up`, Pulumi will print the exported values which include the cluster name and the CloudBeaver service endpoint.
