1. Deploy the teleport-plugin-mattermost helm chart on AWS EKS

    TypeScript

    To achieve the deployment of the teleport-plugin-mattermost Helm chart on an AWS EKS cluster, we need to perform the following steps:

    1. Provision an AWS EKS Cluster: We'll create a managed Kubernetes EKS Cluster, which forms the backbone of our Kubernetes-based applications. This cluster will provide us with a Kubernetes control plane managed by AWS.

    2. Deploy the Helm Chart to EKS: Once we have our EKS cluster up and running, we can then deploy the Helm chart for the Mattermost plugin for Teleport.

    Below is the Pulumi program in TypeScript that walks through this process. This includes setting up the EKS cluster and deploying the Helm chart. The program makes use of the @pulumi/eks and @pulumi/kubernetes packages to create the EKS cluster and deploy the Helm chart, respectively.

    import * as pulumi from "@pulumi/pulumi"; import * as aws from "@pulumi/aws"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Provision an AWS EKS Cluster. // We use the high-level pulumi/eks package which simplifies EKS cluster provisioning. const cluster = new eks.Cluster("teleport-mattermost-eks", { // Define the size and scaling behavior of the node group. desiredCapacity: 2, minSize: 1, maxSize: 3, instanceType: "t2.medium", // Choose an instance type appropriate for your workload. }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Step 2: Deploy the teleport-plugin-mattermost helm chart to the EKS cluster. // We'll create a new Helm Chart resource that points to the Mattermost plugin for Teleport. const teleportMattermostChart = new k8s.helm.v3.Chart("teleport-plugin-mattermost", { chart: "teleport-plugin-mattermost", version: "0.0.1", // Replace with the desired version of the chart. fetchOpts: { repo: "https://charts.releases.teleport.dev" // The Helm repository where the chart is hosted. }, }, { provider: cluster.provider }); // It's important to pass the EKS cluster provider to ensure that Helm installs // the chart in the right Kubernetes Cluster.

    Here's a detailed explanation of what the Pulumi program is doing:

    • The eks.Cluster class from the @pulumi/eks package is used to create a new Amazon EKS cluster. You can define the size and scaling properties of your node group, including the desired capacity, minimum size, and maximum size, along with the instance type that best fits your use case.

    • The program then exports the kubeconfig which is necessary to connect to your Kubernetes cluster with kubectl or other Kubernetes management tools.

    • In the second step, we declare a Helm chart resource using the k8s.helm.v3.Chart class from the @pulumi/kubernetes package. This class is responsible for fetching the Helm chart from the provided repository and deploying it to the EKS cluster.

    • We specify the chart name (teleport-plugin-mattermost), the version of the chart to be deployed, and the Helm repository URL where the chart is hosted.

    • The Helm chart resource is associated with the provider tied to the EKS cluster so that the Helm chart is installed into the correct cluster.

    Remember to replace the version with the desired chart version, and the repository URL with the official one if it's different. Additionally, you will need to configure your AWS credentials for Pulumi to manage resources on your behalf.

    After defining your Pulumi program, you can deploy your infrastructure by running pulumi up. Pulumi will show you a preview of the actions to be taken and prompt you to confirm before making any changes. Once accepted, Pulumi will provision the EKS cluster and deploy the Helm chart as defined.
