1. Deploy the alb-controller helm chart on Digital Ocean Kubernetes Service


    To deploy the alb-controller Helm chart on Digital Ocean Kubernetes Service, you will need to follow these steps:

    1. Create a Kubernetes cluster on Digital Ocean: You will use the digitalocean.KubernetesCluster resource to provision a new Kubernetes cluster. You need to define the region, version, size, name, and other necessary configurations for your cluster.

    2. Install the Helm chart: After setting up the cluster, you use the kubernetes.helm.sh/v3.Chart resource to deploy the alb-controller Helm chart to your cluster. Helm charts are packages that contain pre-configured Kubernetes resources, which allow you to deploy applications or services to a Kubernetes cluster more easily.

    Below is the TypeScript program for Pulumi which does both steps:

    • Starts by importing necessary packages.
    • Declares a Digital Ocean Kubernetes cluster.
    • Deploys the alb-controller using the Helm chart resource.

    Make sure you have Pulumi installed, are logged in (pulumi login), and have the Digital Ocean provider configured with your access token.

    Here is the code with detailed comments explaining each part:

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as k8s from '@pulumi/kubernetes'; // Create a Digital Ocean Kubernetes cluster. const cluster = new digitalocean.KubernetesCluster('do-cluster', { // Specify the region where the cluster will be created region: digitalocean.Regions.NYC1, // Specify the version of Kubernetes to use for the cluster // You can get a list of available versions using `doctl kubernetes options versions` version: 'latest_do_kubernetes', // Define the node pool for the cluster nodePool: { name: 'default', size: digitalocean.DropletSlugs.DropletS2VCPU2GB, nodeCount: 2, // Specify the desired number of nodes in the node pool }, }); // Deploy the alb-controller Helm chart to the cluster. const albControllerChart = new k8s.helm.v3.Chart('alb-controller-chart', { chart: 'alb-controller', // You might need to specify the Helm repository here, for example: // repo: "https://helm-repository-url/", // Specify the version of the chart you want to deploy, or omit for the latest // version: "1.2.3", values: { // Specify any values that you want to override from the default Helm chart values // e.g., enable/disable certain features, configure resources, etc. }, }, { provider: new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Export the cluster properties export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterName = cluster.name; export const clusterEndpoint = cluster.endpoint; // After running `pulumi up`, this code will provision a Digital Ocean Kubernetes cluster // and deploy the alb-controller Helm chart onto it. You can use the exported kubeconfig // to interact with the cluster using `kubectl`.

    To run this code, you will save it to a file index.ts for example, and then run pulumi up. Pulumi will then perform the deployment on Digital Ocean, creating the Kubernetes cluster and configuring the alb-controller Helm chart.

    Remember that the alb-controller Helm chart may require specific configuration values to work as intended. You will need to consult the chart's documentation for the necessary details and modify the values object in the chart resource accordingly.
