1. Deploy the openunison-k8s-cluster-management helm chart on Kubernetes


    To deploy the openunison-k8s-cluster-management helm chart on a Kubernetes cluster using Pulumi, you will be using the kubernetes.helm.v3.Chart resource from the Kubernetes provider. This resource allows you to deploy Helm charts into your Kubernetes cluster in a declarative manner.

    Here's a detailed explanation of the Pulumi program and how it works:

    • First, you need to import the @pulumi/kubernetes package, as it contains the necessary modules to interact with Kubernetes resources within Pulumi.
    • The kubernetes.helm.v3.Chart resource is then used to define the Helm chart installation. The name of the resource is typically set to the name of the Helm release that will be created in the cluster.
    • The chart argument specifies the name of the chart, in this case, openunison-k8s-cluster-management.
    • Since it's not one of the stable charts available, you should specify the repo argument where the chart is located. If, for example, it's located in a Helm repository with the URL https://nexus.openunison.org/repository/helm-hosted/, then you will supply it here.
    • The namespace argument is optional and specifies the Kubernetes namespace into which the chart should be deployed. If omitted, it will be deployed into the default namespace.
    • The values argument represents a set of values you want to pass into your Helm chart. This operates like the values.yaml file that you might use with Helm directly. The values could be the configurations necessary for the chart, such as domain settings, authentication options, or any other configurable parameter.
    • version is another optional property where you can specify which version of the chart you wish to install. If omitted, the latest version will be installed.

    Below is the Pulumi TypeScript program that would deploy the openunison-k8s-cluster-management helm chart to your Kubernetes cluster. Make sure you have Pulumi and the required packages installed and set up correctly, and have access to your Kubernetes cluster.

    import * as kubernetes from "@pulumi/kubernetes"; // Deploy the openunison-k8s-cluster-management helm chart using the kubernetes.helm.v3.Chart resource. const openUnisonChart = new kubernetes.helm.v3.Chart("openunison-k8s-cluster-management", { // Specify the Helm repository URL where the chart is located. repo: "openunison", // Specify the name of the chart. chart: "openunison-k8s-cluster-management", // Define any values required for this particular chart. // Replace these values with your configurations as needed. values: { // For instance, you might configure the domain, email, or other properties: // domain: "example.com", // email: "admin@example.com" }, // Optionally, specify the namespace where the chart should be installed. // If not specified, it uses the default Kubernetes namespace. namespace: "default", // If you wish to install a specific version of the chart, otherwise remove this line. version: "1.0.0", }, { // It's recommended to provide additional options to control the behavior of your deployments. // For example, to skip the await logic which waits for all resources to become ready. skipAwait: true, // You can also specify transformations, dependency updates, etc. }); // Export any output properties you wish to view from this deployment, // e.g., the public URL if your chart creates a LoadBalancer service. export const openUnisonUrl = openUnisonChart.getResourceProperty("v1/Service", "openunison-orchestra", "status") .apply(status => status.loadBalancer?.ingress?.[0]?.hostname || status.loadBalancer?.ingress?.[0]?.ip);

    In this program, we are creating an instance of kubernetes.helm.v3.Chart named openunison-k8s-cluster-management that will install the specified Helm chart onto your Kubernetes cluster. The values property is very important, as it allows you to configure your Helm chart to fit your needs; this should be updated with the actual configuration you intend to use.

    After applying this code with Pulumi (via the pulumi up command), you should see the Helm chart being installed on your cluster. Also, if your chart exposes any services, we have provided a way to extract and export the URL (openUnisonUrl) of the deployed service, which can be accessed if an ingress or LoadBalancer is configured by your Helm chart.

    Remember to replace placeholders and actual values for your Helm chart configurations in the values object, and ensure the chart name, version, and repository URL are correct for your usage.
