1. Deploy the trusted-issuers-registry helm chart on Digital Ocean Kubernetes Service

    TypeScript

    To deploy the trusted-issuers-registry Helm chart on DigitalOcean Kubernetes Service using Pulumi, you'll need to create a few resources:

    1. DigitalOcean Kubernetes Cluster: This is the managed Kubernetes cluster provided by DigitalOcean. You'll deploy your Helm chart onto this cluster.

    2. Helm Chart: Helm is a package manager for Kubernetes, allowing you to define, install, and upgrade complex Kubernetes applications. Helm packages are called charts.

    In the following Pulumi program, we will create a DigitalOcean Kubernetes cluster, and then deploy the trusted-issuers-registry Helm chart into this cluster.

    Step-by-step Pulumi TypeScript Program

    Here is a Pulumi program written in TypeScript that will set up the infrastructure and deploy the Helm chart:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; // Import Pulumi's DigitalOcean package import * as kubernetes from '@pulumi/kubernetes'; // Import Pulumi's Kubernetes package // Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster('trusted-issuers-cluster', { region: digitalocean.Regions.NYC1, // Choose a region for the cluster version: 'latest', // Specify the version of Kubernetes nodePool: { name: 'default-pool', size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // Choose the size of the droplets nodeCount: 3, // Specify the number of nodes in the node pool }, }); // Create a Kubernetes provider using the kubeconfig from the newly created cluster const k8sProvider = new kubernetes.Provider('trusted-issuers-k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig, // The raw kubeconfig from the cluster }); // Deploy the trusted-issuers-registry Helm chart const helmChart = new kubernetes.helm.v3.Chart('trusted-issuers-registry', { chart: 'trusted-issuers-registry', // The name of the chart fetchOpts: { repo: 'http://charts.example.com/', // Replace with the correct Helm repository URL }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // After running `pulumi up`, you can use the exported kubeconfig to interact with your cluster using kubectl

    Explanation

    • First, we import the necessary Pulumi packages for DigitalOcean and Kubernetes.
    • We then create a DigitalOcean Kubernetes cluster using the KubernetesCluster resource. Here you can customize the region, Kubernetes version, droplet size, and the node count.
    • With the cluster created, we use its kubeconfig to create a Pulumi Kubernetes provider. This provider is used to communicate with Kubernetes for deploying resources.
    • We define a Helm chart resource, trusted-issuers-registry, which should be replaced with the name of your actual chart, and specify the repository where the Helm chart is located.
    • Lastly, we export the kubeconfig, which you can use with kubectl to manage your Kubernetes cluster outside of Pulumi.

    After writing your Pulumi program, you will need to run pulumi up to create the resources and deploy your Helm chart to the newly created DigitalOcean Kubernetes cluster. Make sure to have the Pulumi CLI installed, and you are logged in to your Pulumi account.

    Remember that you will need to replace 'http://charts.example.com/' in the fetchOpts block with the actual URL of the Helm repository where your trusted-issuers-registry chart is hosted.

    By exporting kubeconfig you're making it possible to interact with the Kubernetes API using the kubectl tool, which is one way to verify that the Helm chart has been deployed successfully.
