1. Deploy the unauthenticated-ingress helm chart on Digital Ocean Kubernetes Service


    To deploy the unauthenticated-ingress Helm chart on Digital Ocean Kubernetes Service using Pulumi, you will need to perform the following steps:

    1. Create a new Digital Ocean Kubernetes cluster or use an existing one.
    2. Configure Pulumi to use your Digital Ocean access token.
    3. Use the Pulumi Kubernetes provider to deploy the Helm chart to the Kubernetes cluster.

    Firstly, we will need a Digital Ocean Kubernetes cluster. The Pulumi DigitalOcean package allows you to create a cluster. If you already have one, you can skip this step and configure Pulumi to use your existing cluster.

    Here is the TypeScript program that performs these steps:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Set up a Digital Ocean Kubernetes cluster. const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", version: "latest", // Specify your desired Kubernetes version nodePool: { name: "default", size: "s-2vcpu-2gb", // Size of the nodes (this is the smallest size) nodeCount: 2, // Number of nodes in the node pool }, }); // Export the cluster's kubeconfig. export const kubeConfig = cluster.kubeConfigs[0].rawConfig; // Set up a provider to use the exported kubeconfig. const k8sProvider = new kubernetes.Provider("do-k8s-provider", { kubeconfig: kubeConfig, }); // Deploy the Helm chart for unauthenticated-ingress using the Pulumi Kubernetes provider. // Make sure to use the correct repository URL and chart name. const ingressChart = new kubernetes.helm.v3.Chart("unauthenticated-ingress", { chart: "unauthenticated-ingress", version: "0.1.0", // Use the correct chart version namespace: "default", // Deploy to the default namespace, or specify another one }, { provider: k8sProvider }); // Export the ingress endpoint once it is ready. export const ingressEndpoint = ingressChart.getResourceProperty( "v1/Service", "unauthenticated-ingress", "status" ).apply(status => status.loadBalancer.ingress[0].ip);

    Let's walk through what each part of this script is doing:

    • We import the relevant Pulumi packages for Digital Ocean and Kubernetes.
    • We define a new Digital Ocean Kubernetes cluster with specific configurations such as region, Kubernetes version, and node details.
    • We export the kubeconfig of the cluster which will be used by kubectl and the Pulumi Kubernetes provider to interact with the cluster.
    • We set up a Pulumi Kubernetes provider and point it to our Digital Ocean cluster by providing the kubeconfig.
    • We then define a Helm chart resource which represents the unauthenticated-ingress chart. You will have to provide the correct repository URL if it's a custom Helm chart.
    • Finally, we export the ingress endpoint, which will become available once the Helm chart is successfully deployed and the ingress service is allocated an external IP by Digital Ocean.

    To use this script, save it as index.ts in a new Pulumi project directory. You must have Pulumi CLI installed and configured with access to your Digital Ocean account (you can use pulumi config set digitalocean:token YOUR_TOKEN_HERE to configure access).

    Please adapt the chart and version names based on the actual Helm chart you intend to deploy. After setting up, run pulumi up to create the resources. Make sure you have set up your Pulumi stack with the correct Digital Ocean region and token.

    The output ingressEndpoint will give you the external IP address you can use to access your ingress once it is deployed.
