Deploy the tyk-pump helm chart on Rancher

Question

Pulumi · Accepted Answer

Deploying a Helm chart on a Rancher-managed Kubernetes cluster using Pulumi involves a few steps. The process consists of defining the cluster (if not already existing), adding a catalog if needed, and then deploying the chart with its configurations. As your goal is to deploy the Tyk Pump Helm chart on Rancher, we'll focus on the deployment part, assuming that you've already set up a Rancher cluster and have helm configured.

Below is a Pulumi TypeScript program that demonstrates how to deploy the Tyk Pump Helm chart on a Rancher Kubernetes cluster:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as rancher2 from "@pulumi/rancher2";
import * as k8s from "@pulumi/kubernetes";

// Create a new Pulumi stack project.
const projectName = "tyk-pump-deployment";

// Assuming a Rancher2 Kubernetes cluster is already configured and targeted
// We will deploy a Helm chart for Tyk Pump into this cluster.

// Instantiate the Rancher2 provider.
const rancher2Provider = new rancher2.Provider("rancher", {
    apiUrl: "https://your-rancher-api-url", // Replace with your Rancher API URL.
    accessKey: "your-access-key",           // Replace with your Rancher Access Key.
    secretKey: "your-secret-key",           // Replace with your Rancher Secret Key.
});

// Instantiate the Kubernetes provider using the Rancher2 provider credentials.
const k8sProvider = new k8s.Provider("k8s", {
    kubeconfig: rancher2Provider.kubeconfig.apply(JSON.stringify),
});

// Deploy the Tyk Pump Helm chart.
const tykPumpChart = new k8s.helm.v3.Chart("tyk-pump", {
    chart: "tyk-pump",
    version: "0.0.1", // Specify the chart version you wish to deploy.
    fetchOpts:{
        repo: "https://helm.tyk.io/public/helm/charts/", // Tyk Pump Helm repository URL.
    },
    // Define the values for the Helm chart configuration.
    // This is where you can customize your Tyk Pump deployment.
    values: {
        mongodb: {
            enabled: true, // Enable embedded MongoDB.
        },
        // Add more Tyk Pump configuration values here as needed.
    },
}, { provider: k8sProvider });

// Export the status URL of the deployed Helm chart.
export const statusUrl = tykPumpChart.status.apply(status => status.url);
```

This program sets up a new stack for deploying the Tyk Pump Helm chart to an existing Rancher-managed Kubernetes cluster. It uses the Pulumi Rancher2 and Kubernetes providers to perform this action.

Key points of the code:
1. A `rancher2.Provider` is created to interact with the Rancher API, utilizing the API URL and your authentication keys.
2. A `k8s.Provider` is instantiated to manage resources in the Kubernetes cluster. It uses the `kubeconfig` provided by the Rancher2 provider.
3. The `k8s.helm.v3.Chart` resource is used to deploy the Tyk Pump Helm chart from the specified Helm repository to the cluster managed by Rancher.
4. The `values` object allows you to customize the Helm chart configuration as per your requirements (e.g., enabling embedded MongoDB).
5. The Helm chart status URL is exported so that it can be easily accessed after the chart is deployed.

Before you can run this program, you must have Pulumi installed, be authenticated to Pulumi, and have access to the cluster via Rancher.

Please replace `https://your-rancher-api-url`, `your-access-key`, and `your-secret-key` with your own Rancher API URL and credentials.

You’ll need to execute `pulumi up` to deploy this configuration. After deployment, Pulumi will provide you with the output of the `statusUrl` if specified in the chart.

Remember to check [Pulumi Rancher2 documentation](https://www.pulumi.com/registry/packages/rancher2/) and [Pulumi Kubernetes documentation](https://www.pulumi.com/registry/packages/kubernetes/) for more details on provider configuration and resource options.
