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


    To deploy a Helm chart on Kubernetes with Pulumi, you'd typically use the kubernetes.helm.v3.Chart resource. The kubernetes.helm.v3.Chart resource allows you to deploy Helm charts into a Kubernetes cluster. Helm is a package manager for Kubernetes, which enables you to package, configure, and deploy applications and services onto Kubernetes clusters.

    To use the kubernetes.helm.v3.Chart resource, you must have a Kubernetes cluster already set up and configured to interact with your Pulumi code. Pulumi will use the active context in your kubeconfig file unless you configure it otherwise.

    The K8ssandra Helm chart is provided by the maintainers of K8ssandra and is used to deploy K8ssandra, a production-ready platform for running Apache Cassandra on Kubernetes.

    Here is a step by step TypeScript program that shows how to deploy K8ssandra into an existing Kubernetes cluster with Pulumi:

    1. First, ensure that you have Pulumi and Kubernetes set up. Install any Pulumi dependencies via npm or yarn.

    2. Then, in your Pulumi project, you would write the following TypeScript code. The code initializes a new Pulumi project, imports the necessary Pulumi Kubernetes package, and then deploys the K8ssandra Helm chart into the cluster.

    import * as k8s from '@pulumi/kubernetes'; // This Pulumi program deploys the K8ssandra Helm chart on a Kubernetes cluster. // // The Helm chart is deployed by using Pulumi's Kubernetes provider and Helm support. // You must specify the chart name and the repository where the chart can be found. // You can also specify custom values to configure K8ssandra via the `values` field. // Create an instance of the Helm chart. Make sure to provide the correct repository and chart name. const k8ssandraChart = new k8s.helm.v3.Chart('k8ssandra', { chart: 'k8ssandra', fetchOpts: { repo: 'https://helm.k8ssandra.io/' }, // Specify chart values as needed to configure K8ssandra. // For example, to limit the Cassandra cluster to 3 nodes: values: { cassandra: { clusterSize: 3 } } }); // When the program is executed, it uses the active Kubernetes context to deploy the chart. // Ensure you're connected to the intended cluster context when running Pulumi up. // Export any needed resources. // For example, this could export the URL to access services deployed by K8ssandra. export const k8ssandraClusterUrl = k8ssandraChart.getResourceProperty('v1/Service', 'k8ssandra-kube-prom-cassandra', 'status');

    This program creates a new Helm chart instance. It points to the k8ssandra chart in the official k8ssandra Helm chart repository. We set the clusterSize to 3 for the Cassandra cluster as an example configuration, but you can customize the values field to suit your specific configuration needs.

    When you run this Pulumi program with the command pulumi up, Pulumi will reach out to the Helm repository for K8ssandra, download the chart, install it to your cluster, and then output any exported endpoints.


    • The context should point to your intended Kubernetes cluster.
    • The Helm chart and version should be available in the repository provided.
    • The values should be set according to the K8ssandra chart documentation and your requirements.
