1. Deploy the postgres-with-operator helm chart on Digital Ocean Kubernetes Service


    Deploying a Helm chart to a Kubernetes cluster in DigitalOcean involves several steps:

    1. Setting up a DigitalOcean Kubernetes cluster using Pulumi's DigitalOcean provider.
    2. Installing the Helm chart onto the cluster using Pulumi's Kubernetes provider.

    Here's a detailed walkthrough:

    Step 1: Define the DigitalOcean Kubernetes Cluster

    First, we need to create a Kubernetes cluster in DigitalOcean. To do this with Pulumi, you'll use the digitalocean.KubernetesCluster resource. You will define the cluster's name, region, version, node pool, etc.

    Step 2: Install the Helm Chart

    After the DigitalOcean Kubernetes cluster is provisioned, we can deploy the postgres-with-operator Helm chart. Pulumi's kubernetes.helm.v3.Chart resource will help us deploy the chart onto our cluster.

    Step 3: Export the Necessary Information

    Finally, it’s good practice to export any endpoints, such as the Kubernetes cluster endpoint, or other relevant data, like the Kubernetes configuration file, which could be used to connect to the cluster using kubectl.

    Let's put it all together in a Pulumi TypeScript program:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", // Example region, change based on your needs version: "1.20.2-do.0", // Specify a valid version nodePool: { size: "s-2vcpu-2gb", // Example size, change based on your needs name: "default", nodeCount: 3, // Set the number of nodes }, }); // Step 2: Use the Pulumi Kubernetes provider to deploy Helm chart const postgresWithOperatorChart = new kubernetes.helm.v3.Chart("postgres-operator", { chart: "postgres-operator", version: "1.0.0", // Specify the chart version you want to deploy fetchOpts: { repo: "https://charts.your-repo.com/", // Replace with the Helm chart repository URL }, }, { provider: new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Step 3: Export the cluster endpoint and kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterEndpoint = cluster.endpoint;


    • We import the necessary Pulumi libraries for DigitalOcean and Kubernetes.
    • We create a new DigitalOcean Kubernetes cluster with digitalocean.KubernetesCluster. You'll need to specify your region, Kubernetes version, and node pool settings.
    • We create a Kubernetes provider (kubernetes.Provider) that uses the kubeconfig we have from the cluster we created in the previous step.
    • We deploy the Helm chart using kubernetes.helm.v3.Chart. You'll need to specify the chart's name and version and provide the repository URL where the Helm Chart is located.
    • We export the kubeconfig and the cluster.endpoint for future use, such as connecting to the cluster via kubectl or integrating with CI/CD pipelines.

    Please make sure that the chart string points to the correct Helm chart name for deploying Postgres with an operator, and that the version matches the chart version you intend to use. The repository URL should also be updated to point to the actual Helm repository that hosts your desired chart.

    Remember to install the Pulumi CLI, configure it with your DigitalOcean access token and have Node.js with NPM in your development environment. Execute pulumi up within your project directory to create these resources in your DigitalOcean account.
