1. Deploy the clickhouse-cluster helm chart on Kubernetes

    TypeScript

    To deploy a Helm chart for ClickHouse on Kubernetes using Pulumi, you can use the kubernetes.helm.v3.Chart resource from the @pulumi/kubernetes package. This resource allows you to deploy Helm charts from various sources, such as a repository or a local path. In this case, you'll typically want to deploy from an existing Helm repository that hosts the ClickHouse chart.

    In the following program, I'm assuming you have a Kubernetes cluster already running and accessible via your kubeconfig file. Pulumi will use this configuration to deploy resources to your cluster. If you haven't already set up a cluster or connected it to Pulumi, you'll need to do that first.

    Here's a program that deploys the ClickHouse Helm chart into a Kubernetes cluster:

    import * as k8s from '@pulumi/kubernetes'; // Create a new ClickHouse Helm Chart. // Note: There are many configurable values that you can provide to customize your ClickHouse deployment. // These values can be provided through the `values` property. For this example, we are using only default values. const clickhouseChart = new k8s.helm.v3.Chart('clickhouse-cluster', { chart: 'clickhouse', version: 'latest', // Specify the exact chart version you want to deploy fetchOpts: { repo: 'https://path/to/clickhouse/helm/repo', // Replace with the correct repository URL }, }, { provider: k8sProvider }); // Exports export const chartName = clickhouseChart.Chart.metadata.name;

    Make sure you have:

    • Installed Pulumi and set up your cloud provider.
    • Installed Node.js and set up your Kubernetes context so Pulumi can communicate with your Kubernetes cluster.

    In the code:

    1. We import the @pulumi/kubernetes package to access the Kubernetes resources.
    2. We create a new instance of kubernetes.helm.v3.Chart to represent our ClickHouse Helm chart.
    3. In the Chart constructor, we pass an object with the chart and fetchOpts.repo properties set:
      • chart: The name of the chart to deploy. If you're using a chart from the official ClickHouse repository, it might simply be clickhouse. Otherwise, you'll need to find the exact name in the repository you're using.
      • version: The version of the chart to deploy.
      • fetchOpts.repo: The URL of the Helm repository where the ClickHouse chart is hosted.

    After running pulumi up, Pulumi will deploy the ClickHouse Helm chart based on the default values. If you need to customize the deployment, like setting a specific version or providing custom values, you can do so by expanding the values or version fields as necessary.
