1. Deploy the postgresql-persistent helm chart on Digital Ocean Kubernetes Service


    To deploy the postgresql-persistent Helm chart on the Digital Ocean Kubernetes Service using Pulumi, you will need to follow these steps:

    1. Set up the Digital Ocean Kubernetes Cluster: Use Pulumi's Digital Ocean provider to create a Kubernetes cluster in your desired region.

    2. Deploy the Helm Chart to the Cluster: With the Kubernetes cluster in place, you can use Pulumi's Kubernetes provider to deploy the postgresql-persistent Helm chart to your cluster.

    Below is a detailed program written in TypeScript that outlines these steps:

    import * as digitalocean from "@pulumi/digitalocean"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a Digital Ocean Kubernetes cluster. const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", // Choose the region that best suits your needs version: "1.23.5-do.0", // Specify the Kubernetes version nodePool: { name: "default", size: "s-1vcpu-2gb", // You can select a different size based on your needs nodeCount: 2, // Number of nodes you desire in the node pool }, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Step 2: Deploy the `postgresql-persistent` Helm chart using the new cluster's kubeconfig. const postgresChart = new k8s.helm.v3.Chart("postgresql-persistent", { chart: "postgresql", version: "10.3.11", // You will have to specify the chart version you want to deploy fetchOpts: { repo: "https://charts.bitnami.com/bitnami", // This is the repository where the Helm chart is located }, values: { // Here you can put the values you want to override - for example: persistence: { size: "10Gi", // Size of the persistent volume }, // Define more custom values for your postgresql deployment if needed }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }), }); // Export the endpoint to access your Postgres instance export const postgresEndpoint = postgresChart.getResourceProperty("v1/Service", "postgresql-persistent-postgresql", "status").apply(status => status.loadBalancer.ingress[0].ip);


    • The digitalocean.KubernetesCluster is the Pulumi resource used to create a cluster in Digital Ocean. We define the region, Kubernetes version, number of nodes, and droplet size in the cluster configuration.

    • The new k8s.Provider creates an instance that allows Pulumi to interact with the Kubernetes cluster. We pass the kubeconfig of the newly created Digital Ocean Kubernetes cluster to this provider, which is what allows the subsequent resources to be deployed to that cluster.

    • The new k8s.helm.v3.Chart resource deploys the PostgreSQL Helm chart from the specified Helm repository with the version and configuration values you require.

    • We export two values at the end of the program: The kubeconfig, which you can use to interact with your Kubernetes cluster using kubectl or other Kubernetes tools, and the postgresEndpoint, which is the IP address you can use to access your PostgreSQL service from outside the Kubernetes cluster.

    You can run the above program using Pulumi by saving it to a file (for example, index.ts). Ensure you have Pulumi installed and configured to access Digital Ocean with your token. Then execute pulumi up to create the resources. Pulumi will provide you with a detailed preview of the resources that will
