1. Deploy the slack-notifications helm chart on AWS EKS

    TypeScript

    To deploy the slack-notifications Helm chart on AWS Elastic Kubernetes Service (EKS), we'll go through the following high-level steps:

    1. Provision an Amazon EKS Cluster: We'll create an EKS cluster to run our Kubernetes workloads.
    2. Add a Node Group to the Cluster: We'll add a node group to the cluster that will schedule the Kubernetes pods.
    3. Deploy the Helm Chart: Finally, we'll deploy the slack-notifications Helm chart to the EKS cluster.

    Below is the Pulumi TypeScript program that performs these steps. Pulumi's @pulumi/eks package provides high-level abstractions for creating and managing Amazon EKS clusters, so we'll use this to create the cluster and node group. Then, we'll use Pulumi's @pulumi/kubernetes package to deploy the Helm chart to the cluster.

    First, let's create the EKS cluster:

    import * as eks from "@pulumi/eks"; import * as aws from "@pulumi/aws"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("my-cluster", { instanceType: "t2.medium", // Choose an appropriate instance type for your workload. desiredCapacity: 2, // Set the desired number of worker nodes. minSize: 1, // Set the minimum number of worker nodes. maxSize: 3, // Set the maximum number of worker nodes. storageClasses: "gp2", // Set the default storage class for the EKS cluster. deployDashboard: false, // Do not deploy the Kubernetes dashboard (recommended for security reasons). }); // Export the cluster's kubeconfig, which we'll need to connect to the cluster. export const kubeconfig = cluster.kubeconfig;

    Next, deploy the slack-notifications Helm chart:

    // Create a Kubernetes Provider using the kubeconfig from the EKS cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the slack-notifications helm chart onto the EKS cluster. const slackNotificationsChart = new k8s.helm.v3.Chart("slack-notifications", { chart: "slack-notifications", version: "1.0.0", // Specify the chart version you wish to deploy. fetchOpts: { repo: "http://<URL-to-slack-notifications-helm-chart>", // Replace with the appropriate chart repository URL. }, }, { provider: k8sProvider }); // Export the status of the Helm deployment. export const helmDeploymentStatus = slackNotificationsChart.status;

    In the Helm chart deployment, be sure to:

    • Replace <URL-to-slack-notifications-helm-chart> with the URL of the chart repo that contains the slack-notifications chart. You may also need to adjust the version based on the versions available in the chart repository.
    • Check the values and configuration options that the slack-notifications Helm chart provides, as you might need to include them in the Helm chart resource for customized deployment (such as webhook URL and channel configuration).

    To learn more about the used resources and their associated properties, refer to:

    This program assumes you have installed Pulumi cli, have set up your AWS credentials, and have AWS CLI or Pulumi configuration to deploy resources in your account. After writing this program in a file named index.ts, run pulumi up to execute the script, which will create the EKS cluster and deploy the Helm chart.

    Remember to review and configure IAM roles and policies to ensure the principle of least privilege for resources interacting with AWS services.
