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


    To deploy the stateless-istio Helm chart onto a DigitalOcean Kubernetes cluster using Pulumi, you will need to follow these steps:

    1. Create a DigitalOcean Kubernetes Cluster: This will serve as the foundation where your applications will run. You will use the digitalocean.KubernetesCluster resource for this.

    2. Install the stateless-istio Helm chart: After setting up the Kubernetes cluster, you will deploy your Helm chart onto it. For this, you will use the kubernetes.helm.sh/v3.Chart resource. Please note that stateless-istio should be an available chart or you may need to use the proper chart name according to your specific requirements.

    Below is a TypeScript program illustrating how this can be done. This program assumes that you have already set up Pulumi with the necessary cloud provider configuration and the Pulumi CLI is installed on your system.

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Create a DigitalOcean Kubernetes cluster. const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: digitalocean.Regions.NYC3, version: "latest", // Specify your desired Kubernetes version nodePool: { name: "default", size: digitalocean.DropletSlugs.DOS2VCPU8GB, // Choose the desired size for your worker nodes nodeCount: 2, }, }); // Get the kubeconfig from the cluster const kubeconfig = pulumi.secret(cluster.kubeConfigs[0].rawConfig); // Create a provider to use the kubeconfig and then deploy the chart. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the `stateless-istio` Helm chart. const chart = new k8s.helm.v3.Chart("stateless-istio", { chart: "stateless-istio", // You may need to confirm the exact chart name and provide repository details if the chart is not in the default Helm repo. // You would also specify any custom `values` here if required. }, { provider: k8sProvider }); // Export the cluster's kubeconfig. export const kubeconfigOut = kubeconfig;

    Here's what each part of the code is doing:

    • The digitalocean.KubernetesCluster resource creates a new Kubernetes cluster on DigitalOcean. We're specifying the region, the Kubernetes version, and details about the node pool, such as the size of the droplets and the number of nodes.

    • The Kubernetes provider is then created using the kubeconfig obtained from the cluster, allowing Pulumi to communicate with your new Kubernetes cluster.

    • With the Kubernetes provider configured, we create a Chart resource, which tells Pulumi to deploy the specified Helm chart. If the stateless-istio chart requires specific values or is stored in a custom Helm repository, those details would need to be provided here.

    • Lastly, we export the kubeconfig for the cluster so that it can be used to interact with the Kubernetes cluster using kubectl or any other Kubernetes management tool.

    To run this Pulumi program, save it to a file called index.ts, and then execute pulumi up to create the resources. This will provision a new DigitalOcean Kubernetes cluster and deploy the stateless-istio Helm chart to it. Always remember to review the plan provided by pulumi up before confirming the changes, ensuring that all the actions taken by Pulumi are intended.
