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

Question

Pulumi · Accepted Answer

To deploy the Tyk Operator Helm chart on Digital Ocean Kubernetes Service using Pulumi, you'll first need to create a Kubernetes cluster on Digital Ocean. Once your cluster is up and running, you can then use Pulumi with the Helm package to deploy the Tyk Operator.

Below is a step-by-step Pulumi program written in TypeScript that demonstrates how to do this. I've included comments within the code to help you understand what each section is doing.

### Explanation

1. Import necessary packages: To interact with Digital Ocean and Kubernetes resources, you need to import the respective Pulumi packages.
2. Create a Digital Ocean Kubernetes cluster: Define a Kubernetes cluster resource provided by Digital Ocean.
3. Deploy the Tyk Operator Helm chart: Once the cluster is provisioned, use the Helm Chart resource from the Kubernetes package to deploy the Tyk Operator.

Let's go ahead and write the Pulumi program.

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

// Step 1: Create a Digital Ocean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc3",
    version: "1.21.5-do.0",
    nodePool: {
        name: "worker-pool",
        size: "s-2vcpu-2gb",
        nodeCount: 2,
    },
});

// Step 2: Setup a Kubernetes provider instance using the kubeconfig from the newly created Digital Ocean cluster.
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeConfigs[0].rawConfig,
});

// Step 3: Deploy the Tyk Operator using the Helm chart.
const tykOperatorChart = new k8s.helm.v3.Chart("tyk-operator", {
    chart: "tyk-operator",
    version: "0.9.0", // Specify the version of the chart you wish to deploy
    fetchOpts: {
        repo: "https://helm.tyk.io/public/helm/charts/",
    },
    // You can add custom values or use default ones
    values: {
        // If you have any custom values for your Tyk deployment, specify them here.
    },
}, { provider: k8sProvider });

// Export the kubeconfig and the Kubernetes cluster's id
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
export const clusterId = cluster.id;
```

### How to run this program

1. Install the Pulumi CLI and setup your Digital Ocean access token.
2. Create a new directory and initialize a new Pulumi project inside that directory using `pulumi new`.
3. Replace the contents of `index.ts` with the code provided above.
4. Install the required packages using npm or yarn:

```
   npm install @pulumi/digitalocean @pulumi/kubernetes @pulumi/pulumi
   ```

5. Preview the changes by running the `pulumi up` command, which will show you what resources will be created.
6. If everything looks good, confirm the preview to start provisioning the resources.

Please replace the Digital Ocean region, Kubernetes version, size, node count, and Helm chart version with the desired values for your deployment. Additionally, if the Tyk Operator requires specific configuration values, you can specify them in the `values` object.

Remember that this is a real program that will provision resources on your behalf and possibly incur costs, so ensure you're aware of what you're provisioning and its associated costs on Digital Ocean.
