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


    To deploy the servicemesh-istio-resource Helm chart on a DigitalOcean Kubernetes Service (DOKS) cluster using Pulumi with TypeScript, we'll go through several steps:

    1. Set up the DOKS cluster: We will define a KubernetesCluster resource from the digitalocean provider. This represents the Kubernetes cluster itself.

    2. Configure k8s provider to use DOKS kubeconfig: We'll set up a Kubernetes provider that uses the kubeconfig from the created DOKS cluster to ensure that subsequent resources are deployed to that cluster.

    3. Deploy Helm chart using the k8s provider: We will create a Helm Chart resource from the kubernetes provider, pointing it to the servicemesh-istio-resource. We'll assume this chart is publicly available; if it's not, additional configuration might be needed for the chart repository credentials.

    Let's look at how this translates into a Pulumi program:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { // Provide the region where the cluster will be located region: digitalocean.Regions.NYC1, // Specify the version of Kubernetes to deploy version: "latest", // Configure the node pool for the cluster nodePool: { size: digitalocean.DropletSlugs.DropletS2VCPU2GB, name: "default-pool", nodeCount: 2, }, }); // Step 2: Configure a Kubernetes provider const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the Helm chart to the DOKS cluster const istio = new kubernetes.helm.v3.Chart("istio", { // Assuming 'servicemesh-istio-resource' is the name of the Helm chart chart: "servicemesh-istio-resource", // Specify the Helm repo URL if it's not in the default Helm repo fetchOpts: { repo: "https://your-helm-chart-repo.com" }, // If you have custom values, provide them here values: { // Custom values for the Helm chart }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the service endpoint export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const istioEndpoint = istio.getResource("v1/Service", "istio-ingressgateway").status.loadBalancer.ingress[0].ip;

    Here is what we're doing in the code above:

    • We start by importing the necessary modules from Pulumi's digitalocean and kubernetes packages. These will help us define and manage resources on DigitalOcean and Kubernetes.

    • We then create a new DigitalOcean Kubernetes cluster by invoking digitalocean.KubernetesCluster. This takes several parameters, such as the desired region for the cluster, the Kubernetes version, and the configuration of the node pool, which includes the size and count of nodes.

    • Once the cluster is created, we set up a Kubernetes provider configured with the kubeconfig from the DOKS cluster. This provider will be used to interact with the cluster and deploy applications to it.

    • Finally, we deploy the servicemesh-istio-resource Helm chart by creating an instance of kubernetes.helm.v3.Chart. We're assuming that the Helm chart name and repository URL are known. The values object is where you can pass any custom configuration required for the Istio Service Mesh installation.

    • The kubeconfig is exported so you can access it outside of Pulumi, for instance, to use kubectl to interact with the cluster. We also make an educated guess that the Istio Service Mesh exposes an ingress service named istio-ingressgateway and export its IP address.

    Please make sure to replace the chart name and repository URL with accurate information for Istio or the specific service mesh Helm chart you are using. If your Helm chart needs specific versions or setup, make sure to specify that in the version argument and values property.

    Save the file with a .ts extension and deploy with the pulumi up command. Pulumi will perform these operations, providing a detailed preview and summary of the resources created. If this is what you expect, you can proceed with the actual deployment by confirming the prompt.
