1. Deploy the eap-xp3 helm chart on AWS EKS


    To deploy the eap-xp3 Helm chart on an Amazon EKS cluster, you'll need to complete a few steps. We'll use Pulumi's EKS library to create a managed Kubernetes cluster, and then use the Kubernetes provider to deploy the Helm chart into that cluster.

    First, you'll need to create an EKS cluster. In Pulumi, you can do this by defining an EKS cluster resource using @pulumi/eks library which creates and manages the necessary AWS resources like the EKS cluster, NodeGroups, and other components.

    Once the cluster is set up, you'll use the Kubernetes provider, specifically @pulumi/kubernetes, to install the Helm chart. The @pulumi/kubernetes package provides a Chart resource that represents a Helm chart in Pulumi's infrastructure as code framework.

    Let's start by creating a program in TypeScript to accomplish this:

    import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; import * as aws from "@pulumi/aws"; // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("my-cluster", { // Specify the desired version for your cluster. version: "1.21", }); // Export the Kubeconfig so that clients (e.g., kubectl) can communicate with the cluster. export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes provider instance that uses our cluster from above. const provider = new k8s.Provider("provider", { kubeconfig: cluster.kubeconfig, }); // Now, we will deploy the eap-xp3 Helm chart on our EKS cluster. // You must specify the correct chart name and version along with any desired // configurations that the chart requires via the `values` parameter. // This is also where you would define which namespace to install into, // resource overrides, and other chart configurations. const chart = new k8s.helm.v3.Chart("eap-xp3-chart", { chart: "eap-xp3", // Usually, you would specify the version of the chart, so you know what you are deploying: // version: "1.2.3", // You must also specify the repository where your Helm chart is hosted, // if it's not in the default helm repo list. You can use `repo: "http://your-chart-repo.org/"` // values here configure the chart itself values: { // Custom values for the eap-xp3 chart go here. }, }, { provider: provider }); // Optionally, you may want to export some URLs or other data resulting from your deployment. // For example, if your chart exposes a service with an external IP, you could output this. // This is an example and is highly dependent on what your chart actually creates. export const serviceUrl = chart.getResourceProperty("v1/Service", "my-service", "status").apply(status => status.loadBalancer.ingress[0].ip);

    In the above program:

    • We create an EKS cluster using the eks.Cluster resource.
    • We then export the kubeconfig of the cluster. You'll use this to configure kubectl or any Kubernetes client to interact with your cluster.
    • We set up the Kubernetes provider to use the kubeconfig of the created EKS cluster.
    • We deploy the Helm chart named eap-xp3 using the k8s.helm.v3.Chart resource. Note that you would need to provide your own values and potentially a specific Helm chart version and a custom Helm repository location (repo) if this Helm chart is not in the default Helm repository.
    • Optionally, we example an export of a service URL. This is assuming your Helm chart creates a Kubernetes Service with a load balancer that receives an external IP.

    Running this Pulumi program will perform the following actions:

    1. Provision an EKS cluster along with the necessary underlying VPC, IAM, and other AWS infrastructure components.
    2. Deploy the eap-xp3 Helm chart to the EKS cluster.

    Ensure you have Pulumi installed, are authenticated with AWS (having your credentials set up), and run pulumi up to deploy the cluster and the Helm chart. If you need more detailed instructions on how to run the program, please let me know!

    Remember, Helm charts can wildly vary in terms of what they expect for configuration and what sort of Kubernetes resources they manage. Always review the documentation for the Helm chart you are deploying and adjust the values in the Chart accordingly.
