1. Deploy the variant-cron helm chart on Digital Ocean Kubernetes Service


    To deploy the variant-cron Helm chart on Digital Ocean Kubernetes Service (DOKS), you'll need to follow a few steps. I'll guide you through setting up the necessary infrastructure using Pulumi and TypeScript.

    What You'll Do:

    1. Set Up a DOKS Cluster: First, you will create a Kubernetes cluster on DigitalOcean Cloud Services. This provides the environment where your Helm chart will be deployed.
    2. Install the Helm Chart: Once the cluster is ready, you'll deploy the variant-cron Helm chart to the cluster. Helm charts are packages of pre-configured Kubernetes resources.


    Make sure you have the following before you start:

    • Pulumi CLI installed and configured for TypeScript.
    • Access to your DigitalOcean account with the necessary permissions to create resources.
    • helm CLI tool installed (though Pulumi abstracts its usage, it's good practice to have it).

    Step 1: Define Your Pulumi Program

    First, you'll establish your Pulumi program. This will include setting up the DigitalOcean Kubernetes Cluster and then deploying the variant-cron Helm chart to it.

    The digitalocean.KubernetesCluster resource will be used to create your Kubernetes cluster. After the cluster is provisioned, you'll use the kubernetes.helm.v3.Chart resource to deploy the Helm chart.

    Here is the TypeScript program you'll execute to deploy your infrastructure:

    import * as pulumi from '@pulumi/pulumi'; 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', { // You can choose the region that is closest to you. region: 'nyc3', // Select the version of Kubernetes to use. version: 'latest', // Define the node pool for the Kubernetes cluster. nodePool: { name: 'default', size: 's-2vcpu-2gb', nodeCount: 2, // Optionally, you can tag your nodes for organizational purposes. // tags: ['your', 'optional', 'tags'], }, }); // Step 2: Deploy the 'variant-cron' Helm chart to the cluster. // First, obtain the provider configuration from the DigitalOcean cluster resource. const k8sProvider = new kubernetes.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Now, use the Helm Chart resource to deploy 'variant-cron'. const helmChart = new kubernetes.helm.v3.Chart('variant-cron-chart', { chart: 'variant-cron', // Specify the repository containing the 'variant-cron' Helm chart. // If the Helm chart is part of the official Helm repository, you may omit the `repo` attribute. // Otherwise, provide the full URL to the chart repository. // Example: repo: 'https://charts.example.com/', version: '1.0.0', // The version of the Helm chart you want to deploy. namespace: 'default', // The Kubernetes namespace to deploy into. You might need to create it if it's not `default`. }, { provider: k8sProvider }); // Export the DigitalOcean Kubernetes cluster endpoint to access it externally. export const clusterEndpoint = cluster.endpoint; // Export the Kubernetes cluster name, useful for managing the cluster with 'kubectl'. export const clusterName = cluster.name;

    Understanding What This Program Does:

    • It creates a DigitalOcean Kubernetes cluster (KubernetesCluster) in the specified region with the mentioned configuration, including the size and count of nodes.
    • It provisions a Kubernetes provider using the created cluster's kubeconfig. This allows Pulumi to communicate with the new cluster.
    • It uses the Chart resource to deploy the variant-cron Helm chart, which must be hosted on a Helm chart repository. If needed, you can specify additional values and configurations for the Helm chart not covered in this example.

    After Deployment:

    After you've run this Pulumi program, your Digital Ocean Kubernetes Service cluster will be running, and it will have the variant-cron Helm chart deployed. You can manage further operations on this infrastructure using Pulumi updates or kubectl commands against the cluster.
