Deploy the local-static-provisioner helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `local-static-provisioner` Helm chart on a Kubernetes cluster using Pulumi, we will utilize the `kubernetes.helm.v3.Chart` resource. This is a high-level Pulumi resource used to deploy Helm charts. Helm is a package manager for Kubernetes which allows you to define, install, and upgrade complex Kubernetes applications.

The `local-static-provisioner` is a Helm chart that manages the creation of persistent volumes from local storage on a cluster. It is used in situations where you might have local storage on your cluster nodes that you want to make available to your pods.

To use the `Chart` resource, we need to provide it with a chart name and the repository where the chart is located. The chart name and repository URL are specific to each Helm chart. For `local-static-provisioner`, let's suppose the chart is found in the `local-helm-repo` repository at `https://helm.example.com/`. You will need to replace the URL with the actual URL of the repository that contains your `local-static-provisioner` chart.

Below is a Pulumi program in TypeScript that demonstrates how to deploy this Helm chart to your Kubernetes cluster:

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

const namespace = "default"; // The namespace where the chart will be installed.

// Create a Helm Chart resource for the local-static-provisioner
const localStaticProvisionerChart = new k8s.helm.v3.Chart("local-static-provisioner", {
    // Provide the chart name and the repository where it is located.
    chart: "local-static-provisioner",
    version: "2.4.0",  // Specify the chart's version, be sure to change it to the version you want to deploy.
    repositoryOpts: {
        repo: "https://helm.example.com/",
    },
    namespace: namespace, // Specify the namespace where this chart will be installed.
    // Here, you can also configure other chart values, like custom configurations for your provisioner.
}, { dependsOn: [ /* Dependencies like a Namespace or RBAC resources if needed */ ] });

// Export the Chart's status which includes the rendered manifest.
export const chartStatus = localStaticProvisionerChart.status;
```

Make sure that you have the Helm repository added to your Helm CLI and that the chart exists at the provided URL. Also, update the `chart` and `repositoryOpts.repo` fields with the correct chart name and repository URL. The `version` field should match the version of the chart that you want to deploy.

This Pulumi program will instruct Pulumi to reach out to the repository, pull the specified chart and version, and deploy it on the cluster which your `kubeconfig` file points to. The `dependsOn` option can be used if you need to set up dependencies for your chart (not used in this code but provided as a placeholder).

Once this TypeScript program is run with `pulumi up`, it will perform a Helm deployment of `local-static-provisioner` on your Kubernetes cluster. The actual state of the deployment will be reflected in the Pulumi stack outputs and, assuming the Helm chart contains Kubernetes resources like Deployments, StatefulSets, or DaemonSets, these will be created on your cluster.

Remember to set up your Kubernetes cluster and authenticate with it through `kubeconfig` before attempting to deploy the chart.
