1. Deploy the openstack helm chart on AWS EKS

    TypeScript

    To deploy the OpenStack helm chart on AWS EKS using Pulumi, you'll follow these steps:

    1. Set up an EKS cluster: Firstly, you will want to set up an Amazon EKS cluster, which is Kubernetes compatible. Pulumi has a high-level eks package that simplifies EKS cluster creation.

    2. Install Helm: Once you have your Kubernetes cluster, you will use Helm to deploy OpenStack. Helm is a package manager for Kubernetes, allowing you to bundle applications into charts which define, install, and upgrade even the most complex Kubernetes application.

    3. Deploy OpenStack via Helm Chart: Finally, with Helm installed, you'll be able to deploy OpenStack by using the OpenStack helm chart.

    Below is a complete Pulumi TypeScript program to set up an EKS cluster and deploy the OpenStack 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"; // Step 1: Create an EKS cluster. const cluster = new eks.Cluster("my-eks-cluster", {/* ... */}); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Step 2: Create a Kubernetes provider instance using the above-created cluster's kubeconfig. const provider = new k8s.Provider("k8s", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Step 3: Deploy OpenStack using the Helm chart. const openStackChart = new k8s.helm.v3.Chart("openstack", { chart: "openstack", version: "<chart version>", // Specify the version of OpenStack Helm chart you want to deploy fetchOpts:{ repo: "https://openstack-helm-charts.storage.googleapis.com/", // Official Helm chart repository for OpenStack } }, { provider }); // Expose the status of the Helm chart export const helmStatus = openStackChart.status;

    In the above program:

    • We create an EKS cluster. The configuration options like desired node count, instance types, etc. can be provided in the eks.Cluster constructor.

    • The kubeconfig output from the EKS cluster creation is exported, which you can use to interact with your cluster via kubectl.

    • We instantiate a new Kubernetes Provider which is needed for deploying Helm charts into the cluster.

    • We then define a helm.v3.Chart resource to install the OpenStack helm chart. We specify the chart name, version, and repository.

    Notice that this Pulumi program is deploying the OpenStack helm chart in its default configuration. Real-world usage of OpenStack likely requires a more detailed setup, involving setting various OpenStack parameters related to networking, storage, authentication, and more.

    Lastly, remember to check the Helm chart's documentation for the OpenStack chart you are using. Different versions of the chart might have different values or setup requirements. Make sure to replace <chart version> with the actual chart version number you wish to deploy.

    You should run pulumi up to deploy this stack, pulumi stack export to export stack outputs, and pulumi destroy when you want to delete the cluster and all associated resources. Make sure you have AWS configured with the correct access permissions, and have Helm installed locally plus its CLI added to your path, so Pulumi can invoke it to deploy the charts.
