1. Deploy the ibm-db2 helm chart on AWS EKS

    TypeScript

    To deploy the IBM DB2 helm chart on AWS EKS using Pulumi, you'll need to work through a few steps:

    1. Set up an AWS EKS cluster.
    2. Configure your Kubernetes provider to connect to the EKS cluster.
    3. Use the Helm Chart resource from Pulumi's Kubernetes provider to deploy IBM DB2.

    We'll begin by creating an EKS cluster in AWS. This involves setting up the necessary IAM roles, VPC, and security groups. With Pulumi, we can automate the provisioning of all these resources.

    Once the cluster is in place, we can configure Pulumi to use the Kubernetes provider which will interact with your EKS cluster. We will then deploy the IBM DB2 helm chart onto the EKS cluster using Pulumi's Chart resource from the Kubernetes provider.

    Below is an example TypeScript program that will create an EKS cluster and deploy the IBM DB2 helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as aws from "@pulumi/aws"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster. const cluster = new eks.Cluster("db2Cluster", { 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 k8sProvider = new k8s.Provider("db2Provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the ibm-db2 helm chart using the created Kubernetes provider. const db2Chart = new k8s.helm.v3.Chart("db2Chart", { chart: "ibm-db2", version: "<VERSION>", // Replace with specific version number if required fetchOpts: { repo: "https://charts.yourrepository.com/", // Replace with the repository containing the ibm-db2 chart }, }, { provider: k8sProvider }); // (Optional) Export the Helm chart resources. export const db2ChartResources = db2Chart.resources;

    Explanation:

    • eks.Cluster is used to create an AWS EKS cluster. This will automatically handle the setup of your VPC, subnet groups, and other resources that are needed for your cluster.
    • We export the kubeconfig which is needed to interact with your cluster using the Kubernetes CLI or other tools such as Pulumi.
    • We create a Pulumi Kubernetes provider with the exported kubeconfig. This allows Pulumi to communicate with your EKS cluster to manage Kubernetes resources.
    • The k8s.helm.v3.Chart resource is what we use to deploy IBM DB2 onto your EKS cluster. You need to specify the name of the chart ("ibm-db2") and the repository where it is located. Replace <VERSION> with the specific chart version you want to deploy and https://charts.yourrepository.com/ with the URL of the Helm repository.
    • Optionally, you can export the resources created by the Helm chart which can be referenced later if needed.

    Next Steps:

    To apply this Pulumi program, follow these steps:

    1. Install Pulumi CLI on your machine if you haven't already.
    2. Configure AWS credentials on your machine for Pulumi to use.
    3. Create a new directory for your Pulumi project and navigate into it.
    4. Run pulumi new typescript to create a new Pulumi TypeScript project.
    5. Replace the contents of index.ts with the provided code.
    6. Run npm install to install the necessary packages.
    7. Deploy your stack using pulumi up.
    8. Check to ensure that the helm chart is deployed using pulumi stack output db2ChartResources.

    Remember to replace placeholders in the code with actual values for the helm version and repository URL. Also, refer to the chart's documentation for any additional values you may want to customize.
