Deploy the universal-crossplane helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the universal-crossplane Helm chart on Linode Kubernetes Engine using Pulumi, we are going to use the `kubernetes.helm.v3.Chart` resource from Pulumi's Kubernetes package. This allows us to specify a Helm chart and its settings as part of our Pulumi infrastructure as code.

Here's a step-by-step guide on how to use this resource:

1. First, we will create a new file named `index.ts` where our TypeScript code will reside.
2. We'll need to import the necessary Pulumi packages for this operation.
3. Next, we must ensure we have access to a Linode Kubernetes Engine cluster. For this example, we'll assume that the kubeconfig file necessary to connect to the Linode cluster is already set up on the machine where Pulumi is running.
4. We'll deploy the universal-crossplane Helm chart using the `Chart` resource.

The following program accomplishes these steps:

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

// Create a new Helm Chart resource for the universal-crossplane chart.
// Make sure to replace `LINODE_CLUSTER_NAME` with your actual cluster name,
// and provide the appropriate namespace where you want the helm chart to be deployed.
const universalCrossplane = new k8s.helm.v3.Chart("universal-crossplane", {
    chart: "universal-crossplane",
    version: "1.7.1", // Specify the version of the chart you want to deploy.
    fetchOpts: {
        repo: "https://charts.crossplane.io/stable/", // The repository where the Helm chart is hosted.
    },
    // You can specify additional configuration parameters for the chart if necessary:
    values: {
        // Configuration values for the chart, for example:
        // replicaCount: 2,
    },
    // Optionally, specify the namespace where the chart should be installed.
    namespace: "crossplane-system",
});

// Export the endpoint - for this example, we'll just output the name of the chart.
export const chartName = universalCrossplane.metadata.name;
```

In this code, we instantiate a `Chart` resource, which represents a Helm chart, in our case, the `universal-crossplane` chart. The `fetchOpts` property is used to tell Pulumi where to find the chart, and `values` can be used to configure the chart according to your needs. The namespace is specified where the Universal Crossplane will be deployed; please make sure that this namespace exists or is created during the deployment.

Make sure that you have Pulumi installed and configured for use with your Linode account. You will also need `kubectl` configured with access to your Linode Kubernetes cluster. After you place the code into `index.ts`, you can deploy it by running:

```bash
pulumi up
```

This command will prompt you to confirm the deployment after showing you the proposed changes. If everything looks good, confirm the operation, and Pulumi will handle the deployment for you.

Remember to review the chart's configuration options to ensure all necessary values align with your requirements. The example above deploys the latest stable version available at the time of writing this guide, but you should specify the version that you need for your use case.
