1. Deploy the provider-openstack helm chart on Kubernetes


    Deploying a Helm chart on a Kubernetes cluster using Pulumi is straightforward. We'll use the @pulumi/kubernetes package, which allows us to manage Kubernetes resources, including deploying Helm charts. In this case, we need to deploy a Helm chart for OpenStack.

    To use the provided code, you need to have Pulumi installed and configured with access to a Kubernetes cluster. Ensure the Helm chart you want to deploy is available in a Helm repository or local directory.

    Let's go through the process step by step:

    1. First, we will import the necessary packages from @pulumi/kubernetes.
    2. Then, we will instantiate the Helm chart using the Chart class from @pulumi/kubernetes/helm/v3.

    Here's the full TypeScript code to deploy the provider-openstack Helm chart on Kubernetes:

    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the Helm Chart for provider-openstack. // Assume that the chart is available in a Helm repository. const openstackChart = new k8s.helm.v3.Chart("openstack", { chart: "provider-openstack", // Specify the repository where your Helm chart is located. // Replace `repo_url` with the actual URL of the Helm repository. fetchOpts: { repo: "https://helm-repository-replace-with-actual-url.com", }, // You can customize the Helm chart values by specifying the `values` property. // The following is just an example; you should replace with actual values required. values: { // Example of setting a value: // someValue: "some-setting", }, // Namespace where the chart should be deployed; default is `default`. // Replace it with the name of the namespace where you want to deploy the Helm chart. namespace: "openstack-namespace", // If your chart needs specific version, you can specify it here. // version: "1.2.3", }); // Export the base URL of the OpenStack services, which can be used to interact with the deployed OpenStack instance. export const openstackBaseUrl = openstackChart.getResourceProperty("v1/Service", "base-url", "status.loadBalancer.ingress[0].hostname");

    In the above program:

    • We import the @pulumi/kubernetes package to use Kubernetes-related resources in our Pulumi program.
    • We create a new Helm chart resource using k8s.helm.v3.Chart class. This resource uses several parameters:
      • chart: Specifies the name of the Helm chart to be deployed.
      • fetchOpts.repo: Specifies the URL of the Helm repository; you need to replace this with the actual URL of your OpenStack Helm chart repo.
      • values: An object that specifies any custom values you want to pass to the Helm chart, for configuring OpenStack parameters.
      • namespace: The Kubernetes namespace where you want to deploy your Helm chart. You need to specify the namespace according to your environment or use the default one.
      • version: If you want to deploy a specific version of the helm chart, you can uncomment the line and add a version number. Omit this option if you want to deploy the latest version.

    The exported openstackBaseUrl lets you access the base URL for OpenStack services once the stack is successfully deployed and should be tailored to match the actual service name and values of the deployed OpenStack instance. This export line is an example and might need to be adjusted to match the specifics of the OpenStack Helm chart you are deploying.

    After writing this Pulumi program, you save it to a file, for example, index.ts, and run it via Pulumi CLI using the following commands:

    pulumi up # To preview and deploy the changes

    Make sure you check the output of pulumi up for any errors or messages indicating that you need to make adjustments to the program based on your Kubernetes cluster configuration and the OpenStack Helm chart requirements.
