Deploy the prom2teams helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the `prom2teams` Helm chart on Digital Ocean Kubernetes Service using Pulumi, you would first need to set up a Kubernetes cluster on Digital Ocean. Then you can use the Helm chart resource to deploy `prom2teams` to the cluster.

We'll go through the following steps:
1. **Set up a Digital Ocean Kubernetes Cluster:** We'll create a Kubernetes cluster on Digital Ocean.
2. **Deploy the `prom2teams` Helm chart:** We'll then deploy the Helm chart to the Kubernetes cluster.

Below is the TypeScript program that performs these steps using Pulumi:

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

// Step 1: Create a Digital Ocean Kubernetes cluster
// The digitalocean.KubernetesCluster resource creates a cluster in the specified region with a given node count and size.
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc1",  // Replace with the region you prefer
    version: "latest", // Specify the version of Kubernetes
    nodePool: {
        name: "default",
        size: "s-1vcpu-2gb", // Replace with the node size you prefer
        nodeCount: 2, // Specify the desired amount of nodes
    },
});

// Step 2: Deploy the prom2teams Helm chart
// Once the cluster is created, we can use the k8s.helm.v3.Chart resource to deploy the prom2teams chart.

// Initialize a new k8s Provider pointing to the kubeconfig of our Digital Ocean cluster
const k8sProvider = new k8s.Provider("do-k8s", {
    kubeconfig: cluster.kubeConfigs[0].rawConfig,
});

// Deploy the prom2teams Helm chart to the cluster using the k8s.helm.v3.Chart resource
const prom2teamsChart = new k8s.helm.v3.Chart("prom2teams", {
    chart: "prom2teams",
    version: "3.2.2", // Replace with the version of the Helm chart you need
    fetchOpts: {
        repo: "https://prometheus-community.github.io/helm-charts", // Helm chart repository
    },
}, { provider: k8sProvider });

// Export the cluster's kubeconfig and the Helm chart deployment status
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
export const chartStatus = prom2teamsChart.status;

```

### Explanation:

1. We import the necessary Pulumi packages including Digital Ocean (`@pulumi/digitalocean`) and Kubernetes (`@pulumi/kubernetes`).

2. We create a Kubernetes cluster in Digital Ocean with the `digitalocean.KubernetesCluster` resource. You will need to specify the region, the Kubernetes version, the node size, and the number of nodes according to your requirements.

3. With our Kubernetes cluster set up, we initialize a `Provider` resource. It points to the newly created cluster by using its kubeconfig.

4. We then deploy the `prom2teams` Helm chart using the `k8s.helm.v3.Chart` resource. We specify the chart's version and the repository URL from where to fetch the chart.

5. Lastly, we export the kubeconfig of our new Kubernetes cluster, which can be used to interact with the cluster using `kubectl` or other tools. We also export the status of the Helm chart deployment to confirm if the deployment is successful.

Please replace the placeholder values like `region`, `size`, and `version` with the appropriate values for your requirements. You need to have the Digital Ocean and Kubernetes providers set up and configured in your Pulumi project. Once the providers are configured, you can use the Pulumi CLI to deploy this program.
