1. Deploy the cmseek helm chart on AWS EKS


    In order to deploy the CMSeek helm chart on an AWS EKS cluster using Pulumi, you'll need to follow these general steps:

    1. Set up an EKS cluster: This involves creating an EKS cluster in AWS with the necessary configurations.
    2. Configure kubectl for EKS: Set up kubectl to interact with the new EKS cluster.
    3. Add Helm chart to your Pulumi program: Utilize Pulumi's @pulumi/kubernetes package to deploy CMSeek helm chart on EKS.

    The following TypeScript program does these steps using Pulumi. I've included an explanation of each part of the code, detailing what it accomplishes.

    First, you need to set up Pulumi and AWS. Ensure you have the Pulumi CLI installed and configured to use AWS credentials. Install the required Pulumi packages by running:

    npm install @pulumi/pulumi @pulumi/aws @pulumi/awsx @pulumi/eks @pulumi/kubernetes

    Here's a Pulumi program that sets up an AWS EKS cluster and deploys the CMSeek helm chart to it.

    import * as awsx from "@pulumi/awsx"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("my-cluster", { // Specify the desired Kubernetes version. version: "1.21", }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Create a provider to install the helm chart once the cluster is up and running. const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the CMSeek helm chart using the Pulumi Kubernetes provider. const cmseekChart = new k8s.helm.v3.Chart("cmseek-chart", { // If CMSeek helm chart is hosted on a Helm repository, specify `repo` and `chart` properties. // Replace `VERSION` with the specific version of the helm chart you wish to deploy. chart: "cmseek", // You would specify the repository URL if it's not a commonly used Helm chart // e.g., repo: "http://my-helm-chart-repo/" version: "VERSION", fetchOpts: { // If the CMSeek helm chart requires a git repository instead of a standard Helm repository // you can fetch it directly from Git. // repo: "https://github.com/path-to/cmseek-helm-repo", }, }, { provider }); // Export the hostname of the load balancer. export const cmseekHostname = cmseekChart.getResourceProperty('v1/Service', 'cmseek', 'status').apply(status => status.loadBalancer.ingress[0].hostname);


    • We import the necessary Pulumi libraries for working with AWS, EKS, and Kubernetes.
    • We create an EKS cluster with a desired version using the eks.Cluster class.
    • We export the kubeconfig which will be used to interact with the cluster via kubectl.
    • We create a Kubernetes provider with the kubeconfig that points to the EKS cluster.
    • We define the deployment of the CMSeek helm chart using the k8s.helm.v3.Chart class. Note: You have to replace VERSION with the actual version number of the CMSeek Helm chart you want to deploy. If the chart is located in a custom repository or requires specific fetch options (like being cloned from Git), you should properly configure the repo and fetchOpts properties accordingly.
    • Finally, we attempt to export a generated hostname assumed to be provided by a Kubernetes Service of type LoadBalancer, which could expose CMSeek to the internet. Note that this assumes such a service is created in the Helm chart; if not, this export will need to be adjusted accordingly.

    Remember to replace "VERSION" with the actual version of the CMSeek helm chart you want to deploy, and if it isn't available in a public Helm chart repository, specify the correct repo URL or Git repository in fetchOpts.

    After writing the above code in a index.ts file, run the Pulumi program with the following commands:

    pulumi up

    This command will provision the resources in AWS as per the Pulumi code. It might take a few minutes for the EKS cluster and the Helm chart deployment to complete. After everything is provisioned, you should see the outputs, including the kubeconfig and the cmseekHostname, which would be the ingress point to access the CMSeek application.
