1. Deploy the calico-crds helm chart on Digital Ocean Kubernetes Service


    To deploy the calico-crds Helm chart on a DigitalOcean Kubernetes Service (DOKS), we will perform the following steps with Pulumi:

    1. Provision a new DOKS cluster using digitalocean.KubernetesCluster.
    2. Use the kubernetes.helm.v3.Chart resource to deploy the calico-crds Helm chart to the DOKS cluster.

    Let's break down the steps in code using Pulumi's TypeScript SDK:

    Firstly, you'll need to install Pulumi and set up your DigitalOcean token. Pulumi's documentation provides a thorough guide for setup.

    Then, install required npm packages for Pulumi DigitalOcean and Kubernetes provider support:

    npm install @pulumi/digitalocean @pulumi/kubernetes

    Now, I'll walk you through a Pulumi program that performs the deployment:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create a new DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster('doks-cluster', { region: digitalocean.Regions.NYC1, version: 'latest', // Specify the desired Kubernetes version nodePool: { name: 'default-pool', size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // You can adjust droplet size as needed nodeCount: 2, // Specify number of nodes }, }); // Step 2: Deploy the calico-crds Helm chart const calicoChart = new k8s.helm.v3.Chart('calico-crds', { chart: 'calico-crds', fetchOpts:{ repo: 'https://docs.projectcalico.org/charts', // This is the official calico Helm chart repository }, // You may need to specify the chart version and additional values based on your requirements }, { provider: new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

    What's happening in the code:

    1. With the digitalocean.KubernetesCluster class, we create a DigitalOcean Kubernetes cluster. You can specify your desired region, droplet size, the number of nodes, and the Kubernetes version.
    2. We create a new instance of k8s.helm.v3.Chart. This resource represents a Helm chart, which in our case will be the calico-crds chart from the official Calico Helm chart repository.
    3. A new instance of k8s.Provider is created to interact with our newly created cluster. We pass the kubeconfig of our DOKS cluster to this provider to ensure that the Helm chart is deployed to the right cluster.
    4. We export the kubeconfig to enable interaction with the cluster using kubectl or any Kubernetes-compatible tool.

    To understand more about each resource's properties and configurations, refer to Pulumi's documentation:

    After writing this code to a TypeScript file like index.ts, you would typically run pulumi up to provision the resources as per the Pulumi program. Once the deployment is complete, Pulumi will output the kubeconfig, which you can use to interact with your DOKS cluster.
