1. Deploy the openstack helm chart on Rancher

    TypeScript

    To deploy an OpenStack helm chart on Rancher using Pulumi, you would typically perform the following steps:

    1. Set up Rancher in your environment and have access to it.
    2. Create a Rancher cluster where you can deploy workloads.
    3. Add a catalog containing the OpenStack helm chart to Rancher.
    4. Deploy the helm chart from the catalog into your Rancher cluster.

    In this guide, I will write a Pulumi program in TypeScript that assumes you already have a Rancher setup and appropriate access credentials to interact with it. The purpose of the program is to automatically perform steps 2 to 4.

    Here's a walk-through of the program we are about to write:

    • We'll use the rancher2 Pulumi package to interact with your Rancher instance.
    • We'll create a new Kubernetes cluster in Rancher using the rancher2.Cluster resource.
    • Next, we'll add a catalog that contains the OpenStack helm chart to our Rancher setup, which is possible with the rancher2.CatalogV2 resource.
    • Finally, we'll deploy the OpenStack helm chart onto our newly created cluster using the rancher2.AppV2 resource (this is not explicitly listed in the registry results, but it's commonly used along with CatalogV2 for helm chart deployments).

    Let's start with the TypeScript program:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; // Create a new Rancher v2 Cluster const cluster = new rancher2.Cluster("openstack-cluster", { // You may need provider specific configuration here // depending on where you want to deploy your Kubernetes cluster. }); // Add a Catalog that contains the Openstack helm chart const openstackCatalog = new rancher2.CatalogV2("openstack-catalog", { clusterId: cluster.id, url: "https://github.com/openstack/openstack-helm", // Replace with the correct URL to the helm chart repository if needed gitBranch: "main", }); // Deploy the OpenStack helm chart onto the cluster. // Note: The AppV2 resource may need to be configured with specific details for the OpenStack chart. // This will include setting values for required chart values, which can be defined in the `valuesYaml` property. // As of my knowledge cut-off in 2023, the `rancher2.AppV2` resource is typically used for deploying helm charts, // but since Pulumi's registry results do not list it explicitly and might have changed by 2024, // please verify against the latest Pulumi Rancher2 provider documentation for accurate resource and property names. const app = new rancher2.AppV2("openstack-app", { clusterId: cluster.id, namespace: "openstack", // Replace with the namespace you wish to install OpenStack into repoName: openstackCatalog.name, chartName: "openstack-chart-name", // Replace with the actual chart name from the catalog chartVersion: "openstack-chart-version", // Replace with the desired version of the OpenStack chart // valuesYaml is where you specify configuration values for the OpenStack Helm Chart valuesYaml: `key1: value1 key2: value2`, // Replace or extend with actual values required by the OpenStack Helm chart }); // Export relevant data to access the cluster export const clusterName = cluster.name; export const openstackAppName = app.name;

    Before running the above program, you'll need to:

    • Install Node.js and Pulumi.
    • Set up the Pulumi CLI and log in.
    • Configure your environment with access to your Rancher instance, which likely includes setting up a kubeconfig file or obtaining Rancher API tokens.
    • Identify the correct URL for the OpenStack helm chart repository to be used in the openstackCatalog resource.
    • Replace placeholders for the chart name and version in the rancher2.AppV2 resource with actual values corresponding to the OpenStack Helm chart you want to deploy.

    To deploy this stack to your Rancher using Pulumi, simply run pulumi up. The command will display the planned actions and prompt for confirmation before proceeding.

    This program is a basic starting point. The specific deployment of OpenStack via a helm chart can vary widely based on the actual chart and your intended configuration. You will need to adjust valuesYaml with the correct configuration values for the OpenStack Helm chart you're using. Consult the chart's documentation for what values are available and required.
