Deploy the vmware-rest-proxy helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the `vmware-rest-proxy` Helm chart on Digital Ocean Kubernetes Service (DOKS), we'll proceed as follows:

1. Create a Kubernetes cluster on DigitalOcean using the [`digitalocean.KubernetesCluster`](https://www.pulumi.com/registry/packages/digitalocean/api-docs/kubernetescluster/) resource.
2. Once the cluster is available, configure the Pulumi `kubernetes` provider to connect to the newly created cluster.
3. Use the [`kubernetes.helm.v3.Chart`](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/) resource to deploy the `vmware-rest-proxy` Helm chart to the cluster.

Here's a step-by-step Pulumi TypeScript program that accomplishes this. You'll need the Helm chart's repository URL and, if the Helm chart requires, specific configuration values.

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

// Step 1: Create a Kubernetes cluster on DigitalOcean.
const cluster = new digitalocean.KubernetesCluster('do-cluster', {
    region: digitalocean.Regions.NYC3, // Select the region that is appropriate for you
    version: 'latest', // Specify the desired Kubernetes version or use 'latest'
    nodePool: {
        name: 'default-pool',
        size: digitalocean.DropletSlugs.DOS2vCPU8GB, // Choose the appropriate droplet size
        nodeCount: 2, // Specify the desired number of nodes in the node pool
    },
});

// Step 2: Export the kubeconfig to connect to the cluster.
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Step 3 (Optional): Configure the Pulumi Kubernetes provider to connect to the created cluster.
const provider = new kubernetes.Provider('k8s-provider', {
    kubeconfig: kubeconfig,
});

// Step 4: Deploy the vmware-rest-proxy Helm chart.
const helmChart = new kubernetes.helm.v3.Chart('vmware-rest-proxy-chart', {
    chart: 'vmware-rest-proxy', // Name of the Helm chart. Replace if it's different
    version: '1.0.0', // Specify the chart version if necessary
    fetchOpts: {
        repo: 'http://your-helm-chart-repository.com', // The URL of the Helm chart repository
    },
    // Set any required Helm values here
    values: {
        // service: {
        //     type: 'LoadBalancer',
        // },
        // Add other configuration values as needed
    },
}, { provider: provider });

// Step 5: Export the status of the Helm deployment.
export const helmChartStatus = helmChart.status;
```

This program uses Pulumi with the DigitalOcean provider to create a Kubernetes cluster. Then, it sets up a Kubernetes provider to deploy a Helm chart to that cluster. We export the `kubeconfig` and the Helm chart status so you can use the `kubeconfig` to connect to the cluster using `kubectl` and other Kubernetes tools.

The `values` property in the Helm chart resource is a placeholder for any configurations required by the `vmware-rest-proxy` chart. You would need to replace these with actual values based on the chart's requirements.

To deploy this Pulumi program:

1. Ensure you have Pulumi CLI installed and have authenticated with DigitalOcean within Pulumi.
2. Save this code to a file named `index.ts`.
3. Run `pulumi up` in the command line from the directory containing your `index.ts` to deploy the resources.

The `pulumi up` command will show you a preview of the resources that Pulumi will create. If everything looks correct, you can proceed with the deployment by selecting `yes` when prompted.

Please note that you might incur costs on DigitalOcean by running this program, as it will provision actual resources.
