Deploy the kiali-operator helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the Kiali operator as a Helm chart on a Digital Ocean Kubernetes cluster using Pulumi, you'll need to accomplish a few steps:

1. Provision a Digital Ocean Kubernetes cluster, if you don't have one already.
2. Install the Helm Chart for the Kiali operator on your Kubernetes cluster.

First, you need to set up the Digital Ocean Kubernetes cluster, which you can do using Pulumi's Digital Ocean provider. Afterwards, you can deploy the Kiali operator with the Pulumi Kubernetes provider by specifying the Helm chart's repository and chart name.

Here's a Pulumi program in TypeScript that demonstrates how to do both steps:

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

// Step 1: Provision a Digital Ocean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster('do-cluster', {
    region: 'nyc1', // Choose the appropriate region for your cluster
    version: 'latest', // Specify the Kubernetes version
    nodePool: {
      name: 'default',
      size: 's-1vcpu-2gb', // Select the appropriate node size
      nodeCount: 2, // Specify the number of nodes in the node pool
    },
});

// Step 2: Install Kiali Operator Helm chart on the cluster
const kialiOperatorChart = new k8s.helm.v3.Chart('kiali-operator', {
    chart: 'kiali-operator',
    version: '1.29.0', // Specify the version of Kiali operator you want to install
    fetchOpts: {
        repo: 'https://kiali.org/helm-charts',
    },
}, { provider: new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig }) });

// Export the cluster details to access them later
export const clusterName = cluster.name;
export const clusterKubeconfig = cluster.kubeConfigs[0].rawConfig;

```

This program includes two main parts:

1. `digitalocean.KubernetesCluster`: This resource sets up a Kubernetes cluster on Digital Ocean. You need to select the region where you want the cluster to be deployed (`region`), choose the Kubernetes version (`version`), and specify the details for the node pool, including name, size, and node count.

2. `k8s.helm.v3.Chart`: This resource installs the Kiali operator from the Helm repository. You must specify the chart name (`chart`), the chart version (`version`), and the repository URL where the chart can be found (`fetchOpts.repo`). The `provider` argument is used to pass the kubeconfig of the created cluster to the Helm chart resource.

Remember to replace placeholder values such as `region`, `version`, and `size` with the appropriate values for your setup.

After creating this program:

1. Run `pulumi up` in your terminal to provision the resources.
2. Confirm the details, and if everything is as expected, select `yes` to proceed with the deployment.
3. After deployment, you will see the exported cluster name and kubeconfig printed in the console.

Please note that managing Kubernetes clusters and Helm charts involves costs, so make sure to review Digital Ocean's pricing for the resources you are provisioning and Kiali's Helm Chart documentation for any specific configuration you might need.
