Deploy the aws-api-gateway-operator helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the `aws-api-gateway-operator` Helm chart on the DigitalOcean Kubernetes Service using Pulumi, you'll need to follow these steps:

1. Set up a Kubernetes cluster on DigitalOcean using Pulumi.
2. Install the Helm chart on the Kubernetes cluster.

Firstly, you will create the Kubernetes cluster on DigitalOcean using the `digitalocean.KubernetesCluster` resource. This will set up a Kubernetes cluster with the specified node size, region, and version.

After the cluster is provisioned, you'll configure Pulumi to use the Kubernetes cluster by setting up the KubeConfig.

Next, you'll utilize the `kubernetes.helm.v3.Chart` resource from Pulumi's Kubernetes provider to install the `aws-api-gateway-operator` Helm chart into your Kubernetes cluster. The Helm chart is not specified in the Pulumi Registry Results, so you'll need to know the Helm chart's repository URL or have it available locally.

Here's a Pulumi TypeScript program that deploys a Kubernetes cluster on DigitalOcean and installs a Helm chart. Replace `CHART_REPO_URL` with the repository URL where the `aws-api-gateway-operator` Helm chart is located, and `CHART_VERSION` with the version of the chart you wish to install.

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

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc1",
    version: "1.21.5-do.0",
    nodePool: {
        name: "default",
        size: "s-2vcpu-2gb",
        nodeCount: 2,
    },
});

// Export the DigitalOcean Kubeconfig
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Set up a Kubeconfig for the Kubernetes provider to use
const provider = new k8s.Provider("do-k8s-provider", {
    kubeconfig: kubeconfig,
});

// Deploy the aws-api-gateway-operator Helm chart
const chart = new k8s.helm.v3.Chart("aws-api-gateway-operator-chart", {
    chart: "aws-api-gateway-operator",
    version: "CHART_VERSION", // replace with the actual chart version
    fetchOpts: {
        repo: "CHART_REPO_URL", // replace with the actual chart repository URL
    },
}, { provider });

// Export the Helm chart name
export const chartName = chart.metadata.apply(meta => meta.name);
```

In this program, you're creating a Kubernetes cluster with two nodes using the DigitalOcean cloud provider with `@pulumi/digitalocean`. After creating the cluster, you're setting up a Kubernetes provider to interact with the cluster using `@pulumi/kubernetes`. Finally, you're deploying the `aws-api-gateway-operator` Helm chart to the cluster.

You will need to replace `CHART_REPO_URL` and `CHART_VERSION` with the actual URL of the Helm chart repository and the version of the Helm chart you want to use.

Please have Pulumi CLI installed and configure it to communicate with Digital Ocean cloud and your Kubernetes cluster. Once this is set up, run the following commands to deploy your cluster and chart:

```bash
pulumi up
```

This command will execute your Pulumi program, provision the necessary resources on DigitalOcean, and deploy the Helm chart onto your Kubernetes cluster. The output of the command will provide you with important information about the resources being created or updated.
