1. Deploy the Data on Kuberenetes K8ssandra Chart helm chart on Rancher


    To deploy the K8ssandra Chart on Kubernetes through Rancher, you'll need to perform several steps using Pulumi. The K8ssandra Chart is a Helm chart that provides a production-ready platform for running Apache Cassandra on Kubernetes. Rancher, on the other hand, is a Kubernetes management platform that simplifies Kubernetes cluster operation.

    Here are steps we will follow in the Pulumi TypeScript program:

    1. Setup Rancher Kubernetes Cluster: To manage Kubernetes clusters using Rancher, you first need a cluster where Rancher itself is running. We will define a Kubernetes cluster managed by Rancher using the rancher2.Cluster resource.

    2. Install Catalog: Before installing a Helm Chart, you may need to add a catalog to Rancher where K8ssandra is located, or ensure that it's available in Rancher. This can be achieved using the rancher2.CatalogV2 resource.

    3. Deploy Helm Chart: Finally, we will use Pulumi's Helm Chart resource to deploy K8ssandra on the Rancher-managed Kubernetes cluster.

    Here's a detailed program performing the above steps:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; // Create a new Rancher2 cluster const cluster = new rancher2.Cluster("my-k8ssandra-cluster", { // Specify the necessary properties for your cluster, // such as the driver (the cloud service like EKS, GKE, AKS, etc.), node pools, and network settings. // Due to the diverse configuration options across cloud providers, // refer to the Rancher documentation for specific instructions regarding your setup: // https://www.pulumi.com/registry/packages/rancher2/api-docs/cluster/ }); // Register the K8ssandra repository as a Catalog within Rancher const catalog = new rancher2.CatalogV2("k8ssandra-catalog", { // Point this to the URL where the K8ssandra Helm chart can be found, // for example, the GitHub URL if K8ssandra is hosted there. url: "https://k8ssandra.github.io/k8ssandra/", // Replace with real URL if it's different. clusterId: cluster.id, }); // Assuming the K8ssandra helm chart is available in the Rancher Catalog, // we can deploy it using Pulumi's k8s.helm.v3.Chart resource. const k8ssandraChart = new k8s.helm.v3.Chart("k8ssandra", { // The repository where the chart is located should be the specified Catalog name. repo: "k8ssandra-catalog", chart: "k8ssandra", // Specify the version of the Helm chart you wish to deploy. version: "1.0.0", // Replace with the actual version you want to deploy. // Values to pass to the Helm chart, which would configure K8ssandra. // These values will differ based on your needs. // Check the K8ssandra chart's `values.yaml` file for configuration options. values: { monitoring: { grafana: { enabled: true, }, }, // Include any other custom values you require. }, }, { provider: cluster }); // Export relevant endpoints or other important informational properties export const k8ssandraEndpoint = k8ssandraChart.getResourceProperty("v1/Service", "k8ssandra", "status").apply(status => status.loadBalancer.ingress[0].ip);

    In this program, a Rancher cluster is created via the rancher2.Cluster resource. We have mentioned placeholders for setting the different properties of the cluster, which you need to fill out as per your cloud provider specifics.

    Then, we add a new Catalog source from which to install the K8ssandra Helm chart. Replace the url with the actual repository URL of the K8ssandra chart.

    Lastly, we use the Helm Chart resource from Pulumi's Kubernetes package to deploy the K8ssandra chart. This part also includes placeholders for version and values that must be specified as per the actual version you want to deploy and the configuration you want to establish for your K8ssandra deployment.

    The defined k8ssandraEndpoint export will give you the IP address(es) of the K8ssandra services following the deployment, which you can use to access K8ssandra.

    Make sure to replace the placeholders and configurations with the actual values that are relevant to your environment before running the program with Pulumi.
