1. Deploy the datastore helm chart on Kubernetes


    To deploy a Helm chart on a Kubernetes cluster using Pulumi, we can utilize the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes Provider. This resource allows us to specify the details of the Helm chart we want to deploy, such as the chart name, version, repository, and any custom values that need to be applied.

    Here's what we'll do in the following Pulumi program written in TypeScript:

    1. Import the necessary Pulumi Kubernetes package.
    2. Instantiate a new Helm chart resource with the required parameters, such as chart, version, and fetchOpts if you are fetching from a remote repository, or path if you have the chart locally.
    3. Optionally, you can specify the values property to customize the Helm chart with your desired configurations.

    Below is the Pulumi program that deploys a datastore Helm chart on Kubernetes:

    import * as k8s from '@pulumi/kubernetes'; // Create a new Kubernetes Helm Chart resource. const datastoreChart = new k8s.helm.v3.Chart('datastore-chart', { // Replace 'datastore' with the name of your chart chart: 'datastore', // Specify the version of the chart to be deployed version: '1.0.0', // Specify the chart version // Add the repository details if chart is not in the default stable repository fetchOpts: { // Replace with the URL of your chart's repository repo: 'https://charts.example.com/', }, // Include any custom values to override chart values // Values can be specified inline or by providing a file values: { // For example, if the chart has a setting for replicaCount replicaCount: 3, // Other values that your chart supports can be added here }, }); // Optional: export the chart name export const chartName = datastoreChart.metadata.name;

    Here's a breakdown of the Pulumi program above:

    • We import the Kubernetes package provided by Pulumi, which gives us access to resources needed to interact with Kubernetes.
    • We instantiate a Chart resource provided by the Helm package within the Kubernetes provider. This allows us to deploy Helm charts as part of our Pulumi stack.
    • In the Chart resource configuration, we specify details such as the Helm chart to deploy (chart), the version of the chart (version), and the repository from where the chart will be fetched (fetchOpts). Replace 'datastore' with the actual name of your Helm chart and set the repo value to the URL of your Helm chart's repository.
    • We use the values property to provide any custom configurations necessary for the Helm chart. These values will override defaults set in the chart itself.
    • Optionally, we export the name of the chart, which allows this value to be displayed on the Pulumi Console or used by other resources in the same Pulumi program.

    Please replace 'datastore', version, and the repo URL with the appropriate values for your Helm chart. The values property should be modified to include any specific configurations required by your datastore Helm chart.

    Keep in mind that this program assumes that you have a Kubernetes cluster already configured and available to Pulumi, which could be done via Pulumi kubeconfig settings or the default context in your local Kubernetes configuration file (typically located at ~/.kube/config).
