1. Deploy the istio-fortio helm chart on Digital Ocean Kubernetes Service

    TypeScript

    To deploy an istio-fortio Helm chart on Digital Ocean's managed Kubernetes service (DOKS), you'll follow these general steps using Pulumi and TypeScript:

    1. Set up a Kubernetes cluster on Digital Ocean: Firstly, you'll create a new managed Kubernetes cluster on Digital Ocean using Pulumi's digitalocean.KubernetesCluster resource.

    2. Deploy the Helm chart: Once you have a cluster, you'll use Pulumi's kubernetes.helm.v3.Chart resource to deploy the istio-fortio Helm chart onto your DOKS cluster. Helm charts are a convenient way to package and deploy applications on Kubernetes.

    Here's a Pulumi program in TypeScript that will set up the DOKS cluster and deploy the istio-fortio Helm chart onto it:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Create a new DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: digitalocean.Regions.NYC3, version: "1.21.5-do.0", nodePool: { name: "default", size: digitalocean.DropletSlugs.DropletS2VCPU2GB, nodeCount: 2, }, }); // Step 2: Use the Kubernetes provider to connect to the new cluster const provider = new kubernetes.Provider("do-k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }, { dependsOn: cluster }); // Step 3: Deploy the istio-fortio Helm chart on the cluster const chart = new kubernetes.helm.v3.Chart("istio-fortio", { chart: "fortio", // Assuming the chart's name in the Helm repository is "fortio" // Replace `repo` with the URL of the Helm repository where the istio-fortio chart is located repo: "https://furiousgeorge.github.io/helm-charts/", // Make sure to specify the correct repository namespace: "default", // Specify the namespace if it's other than `default` values: { // Specify any custom configuration values here }, }, { provider }); // Export the cluster's kubeconfig and the service endpoint of the Helm chart export const kubeConfig = cluster.kubeConfigs[0].rawConfig; export const serviceEndpoint = chart.getResourceProperty("v1/Service", "default/istio-fortio", "status");

    Let's break down what each part of this program does:

    • Cluster Creation: The digitalocean.KubernetesCluster resource creates a new Kubernetes cluster in the specified region with the specified version and node pool configuration. You can adjust the region, version, and nodePool settings to match your requirements.

    • Provider Configuration: We instantiate a kubernetes.Provider, which uses the kubeconfig of the newly created cluster. This enables Pulumi to deploy resources onto the cluster. The dependsOn: cluster argument ensures the provider waits for the cluster to be available before deploying anything.

    • Helm Chart Deployment: The kubernetes.helm.v3.Chart is used to deploy the istio-fortio Helm chart onto the DOKS cluster that we just created. You should replace the chart, repo, and values fields with the appropriate information for the istio-fortio chart.

    Please note that in the absence of the specific Helm chart for istio-fortio, I have used a placeholder for the chart field and an example repository URL. You should replace these with the actual chart name and repository URL for istio-fortio.

    Finally, metadata information is exported: kubeConfig provides access to the cluster for use with kubectl or other tools, while serviceEndpoint can potentially provide the network endpoint to access the deployed istio-fortio service.

    To run this Pulumi program, place the code in a new Pulumi project directory, and then run pulumi up to create the resources. Make sure you have already set up your Digital Ocean access token with Pulumi CLI using pulumi config set digitalocean:token <YOUR_TOKEN>.

    Remember, you'll also need the @pulumi/digitalocean and @pulumi/kubernetes npm packages installed, which you can add with npm install @pulumi/digitalocean @pulumi/kubernetes.
