1. Deploy the postgres-2-s3 helm chart on Kubernetes


    To deploy a Helm chart on Kubernetes using Pulumi, you can use the Chart resource from the @pulumi/kubernetes package. This allows you to deploy Helm charts as if you were using the Helm CLI. The Chart resource can be set with various properties such as chart, version, repo, and values, which correspond to the usual Helm parameters.

    In this example, I'm assuming you want to deploy a postgres-2-s3 Helm chart. The name suggests this chart might deploy a PostgreSQL database with S3 integration. Since the exact chart isn't listed in the official Helm repository, you may need to provide the specific repo URL where the chart is hosted, along with any configurations the chart expects in the values object.

    The following program demonstrates how you could deploy such a Helm chart on a Kubernetes cluster using Pulumi with TypeScript:

    import * as k8s from "@pulumi/kubernetes"; const namespace = "default"; // Or any other namespace where you want to deploy the chart const postgres2S3Chart = new k8s.helm.v3.Chart("postgres-2-s3", { namespace: namespace, chart: "postgres-2-s3", // Replace with the actual chart name if different version: "1.0.0", // Use the specific version of the chart you want to deploy repo: "https://charts.example.com/", // Replace with actual Helm repository URL values: { // Customize these values based on the configurations provided by the chart postgres: { user: "admin", password: "password", // Be sure to use secrets for sensitive information in production }, s3: { bucket: "my-s3-bucket-name", // Add additional S3 related configurations here }, // Add any other necessary values the chart requires }, }); export const chartName = postgres2S3Chart.metadata.name;

    Let's break down the code:

    • We import the @pulumi/kubernetes package, which provides us with the classes and functions necessary to interact with Kubernetes resources.

    • We define a namespace variable (in this case, default), which is the namespace where our Helm chart will be deployed in the cluster. The namespace should already exist in the Kubernetes cluster, or you can create it separately with Pulumi if needed.

    • We then create a new Chart resource with the name "postgres-2-s3". The chart property should match the name of the Helm chart you want to deploy. The version property is where you specify the version of the Helm chart. The repo property is the URL of the Helm repository hosting your chart.

    • The values property is an object that contains the configuration options provided by the Helm chart. You can set all the necessary parameters here, such as usernames, passwords, and S3 bucket names.

    • Finally, we export the name of the chart as a Pulumi stack output, which can be helpful for debugging or referencing the deployed chart within Pulumi.

    To run this program:

    1. Make sure you have Pulumi installed on your machine.
    2. Ensure you have a Kubernetes cluster and your kubeconfig is properly set up.
    3. Create a new Pulumi TypeScript project or navigate to an existing one.
    4. Place the above code in your project's index.ts file.
    5. Install the necessary npm package by running npm install @pulumi/kubernetes.
    6. Run pulumi up to execute the program and deploy the chart to your cluster.

    Please replace the placeholders (like https://charts.example.com/, postgres-2-s3, and the configurations inside the values object) with the actual values appropriate for your Helm chart. If you're handling sensitive data, use Pulumi's secrets management to keep things like passwords secure.
