1. Deploy the airports-postgres helm chart on Kubernetes


    To deploy a Helm chart on Kubernetes using Pulumi, we'll be using the kubernetes.helm.v3.Chart resource from the Kubernetes provider. This resource is used to create and manage Helm chart resources in a Kubernetes cluster.

    The Chart resource requires a chart name and, optionally, chart values, repository, and namespace among other settings. If your Helm chart has dependencies on other packages in a chart repository, you may need to add a repository URL. For the airports-postgres Helm chart, you would need to specify the chart's repository and any configuration parameters you wish to customize through chart values.

    Below is a TypeScript program that deploys the airports-postgres Helm chart on Kubernetes. The program assumes you have a Kubernetes cluster up and running and that Pulumi is configured to communicate with your cluster.

    import * as k8s from '@pulumi/kubernetes'; // Create a new Helm Chart for the airports-postgres deployment const airportsPostgresChart = new k8s.helm.v3.Chart('airports-postgres', { // Replace with the actual repository if it's different repo: 'my-helm-charts', chart: 'airports-postgres', // Specify the namespace where the chart should be deployed. namespace: 'default', // Values to provide to the Helm chart values: { // You might have specific configuration like usernames, passwords, etc. // These should be replaced with your actual chart values. // // For example, if the airports-postgres Helm chart allows you to specify // a username and password for the Postgres database, you might have: // postgresql: { // username: 'my-username', // password: 'my-password' // } }, // If your Helm chart needs specific versioning, you can specify the version as well. // version: '1.2.3', }); // Export the Chart name export const chartName = airportsPostgresChart.metadata.name;

    In this program:

    • We first import the @pulumi/kubernetes package which contains helpers to interact with Kubernetes resources.
    • We create a new Helm chart instance using the k8s.helm.v3.Chart class. The first parameter of the constructor is a name for the Pulumi resource (airports-postgres).
    • We specify the Helm chart details in the second parameter. This includes the repository's name where the Helm chart is located (replace my-helm-charts with the actual repository name), the chart name airports-postgres, and the Kubernetes namespace where the Helm chart will be deployed (default is used here). You should update these to match your actual Helm chart details.
    • We provide an empty values object, where you can put all the necessary configurations for your Helm chart. For every Helm chart, the set of configurable values might differ. You should refer to the airports-postgres Helm chart's values.yaml file for the exact set of values you can configure.
