Deploy the base-openstack helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy a Helm chart on Kubernetes using Pulumi, you will need to use the `Chart` resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts in a similar way to `helm install` or `helm upgrade`.

### Step-by-Step Guide

1. **Set up your Kubernetes Cluster**: Make sure you have a Kubernetes cluster running and that your `kubectl` is configured to connect to it. Pulumi will use the same configuration as `kubectl` to communicate with your cluster.

2. **Choose Your Helm Chart**: For deploying the base-openstack Helm chart, you would need to know the repository where the chart is hosted and the version of the chart you want to install.

3. **Write Your Pulumi Program**: In your TypeScript program, use the `kubernetes.helm.v3.Chart` class to deploy your Helm chart to the Kubernetes cluster.

4. **Deploy with Pulumi**: After writing the program, deploy it using the Pulumi CLI with the commands `pulumi up`. This will prompt you to review the changes and then perform the deployment to your Kubernetes cluster.

Here's a TypeScript program that demonstrates how to deploy the base-openstack Helm chart:

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

// Replace the placeholders with the actual repository URL and version of your base-openstack Helm chart.
const repoUrl = "https://charts.your-repository.com";
const chartVersion = "0.1.0";  // The version of the Helm chart you want to deploy.

// Define the Helm chart resource.
const baseOpenstackChart = new kubernetes.helm.v3.Chart("base-openstack", {
    // Assuming the chart is available in a reachable Helm repository.
    chart: "base-openstack",
    version: chartVersion,
    fetchOpts: {
        repo: repoUrl,
    },
    // You can specify the values for the Helm chart like so:
    // values: {
    //   key1: value1,
    //   key2: value2,
    // },
});

// When using Pulumi, you don't need to manually run `helm` commands. Pulumi will handle the deployment and management of the resources defined in the Helm chart.
```

When you run this program with Pulumi, it will deploy the base-openstack Helm chart into your Kubernetes cluster. You can define the `values` property in the `Chart` resource to customize the installation of the Helm chart, just like you would with a `values.yaml` file in Helm.

Remember to install the Pulumi CLI and configure Kubernetes and Pulumi correctly to manage your cluster resources. If you need to create or manage the Kubernetes cluster itself, you can also use Pulumi to do so using the relevant cloud provider's resources.
