1. Deploy the plausible-analytics helm chart on Digital Ocean Kubernetes Service


    To deploy the plausible-analytics Helm chart on the Digital Ocean Kubernetes Service using Pulumi, you will go through a few main steps:

    1. Provision a DigitalOcean Kubernetes (DOKS) cluster.
    2. Configure Pulumi to use the DigitalOcean provider.
    3. Deploy the plausible-analytics Helm chart to the DOKS cluster.

    I will guide you through writing a Pulumi program in TypeScript to accomplish this.

    Firstly, you will need to install the necessary Pulumi packages for DigitalOcean and Kubernetes. These packages include the class KubernetesCluster from the DigitalOcean Pulumi provider to create the cluster and the Chart class from the Pulumi Kubernetes provider to deploy the Helm chart.

    Here's a Pulumi program that outlines these steps:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Provision a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { // Specify the region for your cluster region: "nyc3", // Define the Kubernetes version (use a version supported by digitalocean) version: "1.21.5-do.0", // Define the node pool for your cluster nodePool: { name: "default", size: "s-2vcpu-2gb", nodeCount: 2 }, }); // Export the cluster's kubeconfig, which will be used to configure the Kubernetes provider export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Step 2: Create a provider instance using the above kubeconfig const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Step 3: Deploy the 'plausible-analytics' helm chart const plausibleAnalyticsChart = new kubernetes.helm.v3.Chart("plausible-analytics", { chart: "plausible-analytics", // Add the repository where the chart is located fetchOpts: { repo: "https://helm_repo_url_here", // Please replace with the actual repo URL for plausible-analytics }, // You can customize your Helm chart values by providing the 'values' parameter. // values: { // key: "value", // // Additional custom values // }, }, { provider: k8sProvider }); // Optionally, you can export outputs you might want to use later. // For example, if your Helm chart creates a LoadBalancer service, you might want to export the endpoint export const plausibleAnalyticsEndpoint = plausibleAnalyticsChart.getResourceProperty("v1/Service", "plausible-analytics", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Ensure that you have the Pulumi CLI installed and have access to both Pulumi and DigitalOcean accounts. Set up the required access tokens and other credentials as environment variables or use the Pulumi configuration system to provide these values securely.

    Replace "https://helm_repo_url_here" with the actual repository URL where the plausible-analytics Helm chart is located.

    In this program:

    • We declare a new DOKS cluster by instantiating digitalocean.KubernetesCluster. We specify the region, the Kubernetes version, and details of the node pool (like node size and count).
    • After the cluster is provisioned, we export the kubeconfig, which is needed to communicate with the Kubernetes cluster.
    • Then, we create an instance of kubernetes.Provider which is configured using the kubeconfig of the DOKS cluster. This allows Pulumi to perform deployments on the cluster.
    • We deploy the plausible-analytics Helm chart by creating a new instance of Chart, passing the chart name and repository to the fetchOpts. The chart is linked to the provider we defined, which means it will be deployed to the DOKS cluster.

    The plausibleAnalyticsEndpoint export assumes your Helm chart includes a LoadBalancer service and exports its public IP address. If this is not the case, you will need to modify this export to match the resources created by your Helm chart.

    To run this Pulumi program:

    • Create a new directory for your Pulumi project and navigate into it.
    • Run pulumi new typescript to create a new Pulumi TypeScript project.
    • Replace the contents of index.ts with the code from above.
    • Run npm install to install all dependencies.
    • Run pulumi up to execute the Pulumi program and provision the resources.

    After running pulumi up, you should see the output indicating that the Kubernetes cluster is being created, followed by the deployment of the Helm chart. If there are any issues with the deployment, Pulumi will provide detailed error messages to help diagnose the problem.

    Remember to replace the placeholder URL for the Helm repo with the actual URL. If you don't have the Helm chart repository URL, you will need to obtain it from the maintainer of the plausible-analytics Helm chart or the Helm Chart repository it is hosted on.
