Deploy the tyk-operator helm chart on Oracle Kubernetes Engine (OKE)

Question

Pulumi · Accepted Answer

To deploy the Tyk Operator using the Helm chart on Oracle Kubernetes Engine (OKE), you’ll first need to ensure you have an OKE cluster up and running. The Tyk Operator leverages Kubernetes Custom Resource Definitions (CRDs) to control and manage the Tyk API Gateway. Here's how you can accomplish this using Pulumi with TypeScript:

1. **Set up Oracle Kubernetes Cluster**: Before deploying the Tyk Operator, you need to have a Kubernetes cluster on Oracle Cloud. You can create one using Pulumi’s OCI (Oracle Cloud Infrastructure) package. For simplicity, I am assuming you already have a cluster provisioned and your `kubeconfig` file is configured correctly to connect to your Oracle Kubernetes cluster.

2. **Install the Tyk Operator Helm Chart**: After setting up your Kubernetes cluster, you will install the Tyk Operator Helm chart. You can use Pulumi’s Kubernetes package to deploy resources using Helm charts.

Here is the detailed TypeScript program for Pulumi:

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

// The following program assumes that you have an existing Kubernetes cluster in OKE.

// Create a Helm Chart resource that installs the Tyk Operator.
// Replace `REPO_URL` with the URL of the Tyk Operator Helm repository.
// Replace `VERSION` with the version of the Tyk Operator Helm chart that you wish to use.
const tykOperatorChart = new k8s.helm.v3.Chart("tyk-operator", {
    chart: "tyk-operator",  // The name of the chart to deploy
    fetchOpts: {
        repo: "REPO_URL",  // Helm repository URL for the Tyk Operator
    },
    version: "VERSION",  // Helm chart version
    // Set any Helm values here that you would like to override.
    values: {
        // Custom values to override defaults of the chart.
        // Refer to the Tyk Operator Helm chart documentation for available options.
        // For example:
        // gateway: {
        //     enabled: true,
        // },
        // dash: {
        //     enabled: false,
        // }
    },
});

// Export the Helm chart resources' status
export const tykOperatorStatus = tykOperatorChart.status;

```

This program declares the use of the Tyk Operator Helm chart and assumes that you're substituting `REPO_URL` with the actual repository URL and `VERSION` with the chart's version you want to deploy. The `values` field within the chart allows you to specify any configurations you want to override in the Helm chart. Be sure to check the Tyk Operator Helm Chart [documentation](https://artifacthub.io/packages/helm/tyk-helm/tyk-operator) for all configurable options.

You can then run this program with `pulumi up`, and the Tyk Operator will be deployed to your OKE cluster. It's critical that your Pulumi stack is configured correctly for your Kubernetes environment. Pulumi will automatically use your kubeconfig file when connecting to your Kubernetes cluster; consequently, you should ensure that your kubeconfig is configured for the correct context.

Keep in mind that in terms of Oracle-specific setup, you'll want to refer closely to the [Oracle Cloud Infrastructure - Pulumi](https://www.pulumi.com/registry/packages/oci/) documentation for specifics on setting up and configuring your OKE cluster if you haven't done so already.
