Deploy the localpathprovisioner helm chart on Oracle Kubernetes Engine (OKE)

Question

Pulumi · Accepted Answer

To deploy the `localpathprovisioner` Helm chart on an Oracle Kubernetes Engine (OKE) cluster, we are going to perform the following steps:

1. Import the necessary Pulumi packages.
2. Ensure we have access to the OKE cluster.
3. Deploy the Helm chart to the cluster.

We will primarily focus on the Pulumi Kubernetes package, which allows us to interact with Kubernetes resources, including deploying Helm charts. The `localpathprovisioner` is a Helm chart, so we will use the `kubernetes.helm.v3.Chart` resource to manage the deployment.

The `kubernetes.helm.v3.Chart` resource is a high-level abstraction that deploys a Helm chart from a repository. We will provide it with the chart name, any custom values needed by the chart (if any), and the namespace where we want the chart to be deployed. If you don't already have a specific namespace where you want to deploy your `localpathprovisioner`, it's best practice to create one.

Here is the TypeScript program to deploy the `localpathprovisioner` Helm chart on an OKE cluster with Pulumi:

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

// You need to configure Pulumi to use your Kubernetes cluster. This configuration is
// typically done through the Pulumi config and will not be covered here. You should
// ensure that your current kubeconfig file is pointing to your OKE cluster.

// Using the Kubernetes package, we create a Helm Chart resource.
// This code assumes that you have already set up and connected to your OKE cluster and that
// Pulumi is configured to use the correct context.

// Deploy the `localpathprovisioner` Helm chart
const localpathProvisionerChart = new k8s.helm.v3.Chart('localpathprovisioner', {
    // The repository where the Helm chart is located
    repo: 'rancher',
    chart: 'local-path-provisioner',
    // Optionally, you can specify the version of the chart to be deployed
    version: '0.0.19', // Use the version required for your deployment
    // Specify which namespace the chart should be deployed into
    namespace: 'default', // Replace with your desired namespace or create one if needed
    // Optionally, you can override the default values in the Helm chart with custom values
    values: {
        // Provide any custom values that you need to pass to the chart
        // For example: storageClass: { ... }
    },
}, { provider: okeProvider }); // Replace `okeProvider` with your OKE cluster's provider if needed

// Export the resources' names and status
export const chartName = localpathProvisionerChart.name;
export const chartStatus = localpathProvisionerChart.status;
```

In this program, replace `'rancher'` with the correct Helm repository where the `localpathprovisioner` chart is hosted if it is different. The `version` field should correspond to the specific version of the `localpathprovisioner` Helm chart you want to deploy.

Notice that we are assuming that the Pulumi project is configured with an OKE provider (`okeProvider`). You may need to instantiate the OKE provider or configure it depending on your setup. If your kubeconfig is set up to point to the OKE cluster and it is the default context, you may not need to specify the provider explicitly, and Pulumi will use the default provider configuration.
 
After you've set up your Pulumi program, you would run `pulumi up` in your command-line environment to deploy the `localpathprovisioner` to your OKE cluster. This command will initiate the deployment process managed by Pulumi, and you will be able to see the progress and any errors in your terminal.

Keep in mind that managing Kubernetes resources through Pulumi requires you to understand Kubernetes concepts and the structure of Helm charts. You need to ensure that the values provided in the `values` object correctly configure the Helm chart according to your needs.
