1. Deploy the discord-bot helm chart on AWS EKS


    To deploy a Discord bot using the Helm chart on AWS EKS, we'll need to accomplish several tasks:

    1. Create an EKS cluster where the bot will run. We'll use the aws.eks.Cluster managed by the Pulumi AWS provider for this.
    2. Deploy the Discord bot using the Helm chart. We'll leverage the kubernetes.helm.sh/v3.Chart resource from the Pulumi Kubernetes provider to install Helm charts.

    For the EKS cluster creation, we would typically need:

    • An IAM role for the EKS cluster, for which we use the aws-iam.EKSRole resource.
    • An EKS cluster with associated VPC and Subnet configurations, managed using the aws.eks.Cluster resource.

    Once the EKS cluster is up and running, we will deploy the Discord bot Helm chart onto it. This will include specifying the Helm chart's repository, name, and any necessary configurations, using the kubernetes.helm.sh/v3.Chart resource.

    Here's how you can use Pulumi to create an EKS cluster and deploy a Helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as aws from "@pulumi/aws"; import * as k8s from "@pulumi/kubernetes"; import * as eks from "@pulumi/eks"; // Create an EKS cluster. const cluster = new eks.Cluster("my-cluster", { instanceType: "t2.medium", desiredCapacity: 2, minSize: 1, maxSize: 2, storageClasses: "gp2", deployDashboard: false, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Use the EKS cluster's kubeconfig to create a Kubernetes provider instance. const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the discord-bot helm chart using the created Kubernetes provider. const discordBotChart = new k8s.helm.v3.Chart("discord-bot", { chart: "discord-bot", version: "1.0.0", // replace with the actual chart version fetchOpts: { repo: "https://charts.example.com/", // replace with the actual Helm chart repository URL }, }, { provider }); // Export the required resources. export const clusterName = cluster.eksCluster.name; export const discordBotChartStatus = discordBotChart.status;

    This Pulumi program does the following:

    • It initializes an EKS cluster with a specified instance type and desired capacity using the eks.Cluster class. Adjust these specifications according to the expected load and availability requirements for your Discord bot.
    • It exports the cluster's kubeconfig, which is used to interact with the Kubernetes cluster and to set up the Kubernetes provider. The provider is required to deploy Kubernetes resources (like the Discord bot) onto the cluster.
    • It then uses a Helm chart to deploy the Discord bot. You must specify the chart version and repository where the Helm chart is located. Replace the placeholder URL https://charts.example.com/ with the URL of the Helm chart repository that contains the Discord bot chart.
    • Finally, the program exports the name of the EKS cluster and the status of the Discord bot Helm chart deployment.

    Please note that the Helm chart name (discord-bot) and version (1.0.0) are placeholders. You should replace them with the actual name and version of the Discord bot Helm chart that you wish to deploy. Also, replace the repo URL with the actual repository URL containing your desired Helm chart.

    Remember, running this Pulumi program will require AWS credentials configured for the Pulumi CLI. This EKS cluster creation will incur costs on your AWS account based on the resources provisioned and the duration they are active. Always ensure to destroy the resources using Pulumi CLI's destroy command when they are no longer needed, to avoid unnecessary costs.
