1. Deploy the chromium-render helm chart on Digital Ocean Kubernetes Service


    To deploy the chromium-render Helm chart on Digital Ocean Kubernetes Service (DOKS), you will need to follow these steps:

    1. Create a Kubernetes cluster in Digital Ocean.
    2. Configure kubectl to connect to your Kubernetes cluster.
    3. Add the Helm repository that contains the chromium-render chart.
    4. Install the chromium-render chart on your cluster using Helm.

    Below is a Pulumi TypeScript program that performs these steps. First, the program creates a Kubernetes cluster on Digital Ocean. Then, it uses the kubernetes package to deploy the chromium-render Helm chart.

    Before running this code, you should have Pulumi installed and set up with your Digital Ocean token. If you don't have a token or your Pulumi CLI configured for Digital Ocean yet, you will need to create a token in your Digital Ocean dashboard and then configure Pulumi to use it.

    Detailed Program Explanation

    Kubernetes Cluster on Digital Ocean

    The first step is to create a Kubernetes cluster on Digital Ocean using the digitalocean.KubernetesCluster resource. You will need to specify the region, the version of Kubernetes you want to use, and the details of the node pool (size and number of nodes).

    Helm Chart Deployment

    After the cluster is created, you'll configure Pulumi to use the Kubernetes cluster by setting up a provider instance. Then, you'll deploy the chromium-render Helm chart using the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider, which allows you to manage Helm chart deployments in a declarative way.

    The Helm chart is not installed directly from a repository URL here because the specific repository might require adding to the local Helm configuration first (helm repo add). In a typical Pulumi program, you would need to ensure the repository is added to your local Helm config, but the example assumes that the chart is either already available in your configured Helm repositories or bundled in your local filesystem.

    Let's proceed with the actual Pulumi TypeScript program:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a Kubernetes cluster on Digital Ocean. const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", version: "1.21.5-do.0", nodePool: { name: "default", size: "s-2vcpu-2gb", nodeCount: 2 // Adjust the node count as per your requirements } }); // Once the cluster is created, we create a Kubeconfig file that Pulumi can use to communicate with the cluster. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Step 2: Install the chromium-render Helm chart on the cluster. // Use the cluster's kubeconfig for the Helm chart deployment. // Define the k8s provider using the cluster's kubeconfig const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: kubeconfig }); // Install the chromium-render helm chart const chart = new kubernetes.helm.v3.Chart("chromium-render-chart", { chart: "chromium-render", // Use the appropriate repository and chart version that includes the 'chromium-render' chart. // If the chart is hosted on a custom Helm repository, provide the 'repo' field. // Example: repo: "https://example.com/helm-charts" version: "1.0.0", // Use the correct version of the Helm chart. // You can override default values here using the 'values' property values: { // For example, to change service type to LoadBalancer // service: { type: "LoadBalancer" } }, }, { provider: k8sProvider }); // Export the public endpoint of the chromium-render service export const chromiumRenderEndpoint = chart.getResourceProperty("v1/Service", "chromium-render", "status").apply(status => status.loadBalancer.ingress[0].ip);

    In the above program, replace the version value with the actual version of chromium-render you want to deploy. Also, if chromium-render is hosted on a custom Helm repository, you must specify the repo field with the repository URL.

    After you run pulumi up with this program, Pulumi will perform the deployment, and if everything is configured correctly, the chromium-render Helm chart will be deployed to your Digital Ocean Kubernetes cluster. The endpoint of the service will be exported so you can easily access it.
