Deploy the exoscale-cloud-controller-manager helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy a Helm chart on Kubernetes using Pulumi, you would first need to set up a Kubernetes cluster where the Helm chart will be deployed. For this example, I'll assume you already have a Kubernetes cluster running and configured to work with Pulumi. Below, I'll provide you with a Pulumi program written in TypeScript that will deploy the `exoscale-cloud-controller-manager` Helm chart on your Kubernetes cluster.

Pulumi provides a way to work with Helm charts through its Kubernetes provider. You can use the `kubernetes.helm.v3.Chart` class from the Pulumi Kubernetes provider to deploy Helm charts.

Here's the program that accomplishes this:

```typescript
import * as kubernetes from '@pulumi/kubernetes';

const exoscaleCcmChart = new kubernetes.helm.v3.Chart('exoscale-ccm', {
    chart: 'exoscale-cloud-controller-manager',
    // You can specify the repository that hosts the Helm chart if it's not in the default repo.
    // For this example, I'm using a placeholder URL; you need to replace it with the actual repository URL.
    // repo: 'https://charts.exoscale.com/',
    // version: '1.0.0', // specify the chart version you'd like to deploy
    values: {
        // Here you'd add any custom values you want to pass to your Helm chart. For instance:
        // image: {
        //     repository: 'exoscale/ccm',
        //     tag: 'latest'
        // },
        // You'll need to provide actual values that are appropriate for the exoscale-cloud-controller-manager chart.
    },
}, {
    provider: clusterProvider, // Assuming 'clusterProvider' is the reference to your cluster's K8s provider.
});

// You can export the status of the deployment or other relevant information you might need.
export const exoscaleCcmChartStatus = exoscaleCcmChart.status;
```

Let's go through the program:

- We're importing the `@pulumi/kubernetes` package, which contains the necessary classes to interact with Kubernetes resources using Pulumi.
- We're creating a new instance of `kubernetes.helm.v3.Chart` which Pulumi will recognize as a Helm chart deployment. You'll need to name your deployment and configure it with specifics related to the `exoscale-cloud-controller-manager`.
- In the `chart` field, you specify the name of the chart.
- The `repo` field should point to the Helm repository that contains your chart. This URL will depend on where the `exoscale-cloud-controller-manager` Helm chart is hosted. If it's hosted at a Helm repository, you'll need to find the exact URL for that repository and use it here.
- The `version` field allows you to specify which version of the Helm chart to deploy. If omitted, it will deploy the latest version by default.
- The `values` field is where you would override default values set by the Helm chart. These can be any configurable options that the chart provides.
- The `provider` field attaches this Helm chart to a specific Kubernetes provider, which represents the cluster where you're deploying the chart. Replace `clusterProvider` with your Kubernetes provider instance.

To run this Pulumi program:

1. Ensure you have Pulumi installed and configured for use with your Kubernetes cluster.
2. Ensure the K8s cluster kubeconfig is set up correctly for Pulumi to access your cluster.
3. Save the above code to a file with a `.ts` extension, for example, `deploy-exoscale-ccm.ts`.
4. Run `pulumi up` from the command line in the same directory where your `.ts` file is located.

This will instruct Pulumi to carry out the deployment according to the specified configuration. If you need to configure the Helm chart with specific values for `exoscale-cloud-controller-manager`, replace the placeholders in the `values` field with real configurations needed for your use case.

Please replace placeholder values like the Helm repository URL (`repo`) and configurations inside the `values` object with actual values that apply to `exoscale-cloud-controller-manager`. You can find these details in the chart's documentation or by contacting Exoscale for the required Helm chart information.

Remember, Pulumi manages state and resources for you, so it's good practice to keep track of the resources it manages by saving and committing the generated Pulumi project files.
