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


    To deploy the calico-aws Helm chart on a DigitalOcean Kubernetes Service using Pulumi, you will need to perform the following steps:

    1. Create a DigitalOcean Kubernetes cluster.
    2. Deploy the Helm chart for Calico on the newly created Kubernetes cluster.

    Below is a Pulumi program written in TypeScript that accomplishes these tasks. In this example, I'm using the DigitalOcean provider to create the cluster and the Kubernetes provider to deploy the Helm chart. The calico-aws Helm chart doesn't specifically exist, but I will demonstrate deploying a generic Helm chart that you can modify to specify the right parameters for Calico or another suitable network plugin that is compatible with DigitalOcean Kubernetes service.

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", // Choose the region that is appropriate for you version: "latest", // Specify the version for your Kubernetes cluster nodePool: { name: "default-pool", size: "s-2vcpu-2gb", // Choose the appropriate size for your workload nodeCount: 1, // Specify the number of nodes }, }); // Export the kubeconfig to access the cluster export const kubeConfig = cluster.kubeConfigs[0].rawConfig; // Create a provider resource to interact with your cluster using the kubeconfig const clusterProvider = new kubernetes.Provider("do-cluster-provider", { kubeconfig: kubeConfig, }); // Deploy the "calico-aws" helm chart on the DigitalOcean Kubernetes cluster const calicoChart = new kubernetes.helm.v3.Chart("calico-aws", { chart: "calico", // The chart name, make sure to use the correct chart name for Calico version: "0.1.0", // Specify the chart version you want to deploy namespace: "kube-system", // Typically network plugins are installed in the kube-system namespace // Values in here will override the default values from the Helm chart values: { // Specify necessary values based on the chart documentation }, }, { provider: clusterProvider }); // Export the cluster's name and kubeconfig export const clusterName = cluster.name; export const k8sProvider = clusterProvider;

    This Pulumi program does the following:

    • It defines a DigitalOcean Kubernetes cluster with a specified region, version, and node pool configuration.
    • Outputs the kubeconfig which can be used to interact with the Kubernetes API of the newly created cluster.
    • Sets up a Kubernetes provider instance to deploy resources to this cluster.
    • Uses a Chart resource from the Pulumi Kubernetes provider to deploy the Calico Helm chart to the cluster. Note that calico and 0.1.0 are placeholders, and should be replaced with the correct values for the actual Calico chart you want to deploy.

    To run this Pulumi program, you would need to:

    1. Install Pulumi and set up the DigitalOcean access token.
    2. Write this code in a file (e.g., index.ts if creating a new Pulumi project).
    3. Run pulumi up to create the resources. Pulumi will show you a preview of the resources that will be created and prompt you to confirm the deployment.

    Make sure to replace the placeholder values with actual values that are suitable for your specific use case. For the most accurate chart and version names, check the official Calico documentation or Helm repository where the Calico chart is hosted.
