1. Deploy the tt-workflow-driver helm chart on AWS EKS

    TypeScript

    To deploy the tt-workflow-driver Helm chart on AWS EKS, we will follow these steps:

    1. Create an Amazon EKS cluster using Pulumi's eks.Cluster resource, which automatically sets up the necessary infrastructure, like the EKS control plane, worker nodes, and associated resources.
    2. Once the EKS cluster is provisioned, we'll install the tt-workflow-driver Helm chart into our EKS cluster using Pulumi's kubernetes.helm.v3.Chart resource, which allows us to manage Helm charts in a Kubernetes cluster.

    Below is a detailed TypeScript program that creates an EKS cluster and deploys the 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("eksCluster", { instanceType: "t2.medium", desiredCapacity: 2, minSize: 1, maxSize: 2, }); // Get the kubeconfig from the EKS cluster const kubeconfig = cluster.kubeconfig.apply(JSON.stringify); // Create a Kubernetes provider pointing to the created EKS cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Deploy the tt-workflow-driver Helm chart to the EKS cluster const ttWorkflowDriverChart = new k8s.helm.v3.Chart("tt-workflow-driver", { chart: "tt-workflow-driver", // Make sure to replace these values with the actual repository and version fetchOpts: { repo: "https://helm-repository-url-example.com", // Helm repository URL }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the endpoint export const kubeconfigOut = kubeconfig; export const clusterEndpoint = cluster.core.endpoint;

    Explanation:

    • We import necessary modules from Pulumi's SDK to interact with AWS and Kubernetes.
    • We create an EKS cluster with the eks.Cluster resource. You specify the desired instance type and the number of nodes. You can modify these parameters based on your requirements.
    • We extract the kubeconfig from the EKS cluster, which is needed to interact with the Kubernetes cluster.
    • A k8s.Provider is instantiated with the kubeconfig which tells Pulumi how to communicate with the EKS cluster.
    • We then define the tt-workflow-driver Helm chart using the k8s.helm.v3.Chart resource. You must specify the URL to the repository that contains the Helm chart and the release version if required.
    • Finally, we export the kubeconfig and the endpoint of the EKS cluster for easy access.

    Please replace "https://helm-repository-url-example.com" with the actual URL to the Helm chart repository where tt-workflow-driver is located, and specify other chart-related configurations as needed.

    Next Steps:

    1. Save the above code to a file named index.ts.
    2. Run pulumi up to deploy the EKS cluster and the Helm chart to AWS.
    3. Once the deployment is complete, Pulumi will output the EKS cluster endpoint and the kubeconfig which you can use to interact with your Kubernetes cluster.

    Please ensure you have AWS credentials configured for Pulumi CLI, either through the AWS CLI or by setting environment variables (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY). Also, ensure you've installed Pulumi CLI and initialized a Pulumi project. If you need to customize the deployment further, like setting up VPC configurations or enabling advanced features, you can refer to EKS Cluster documentation and Helm Chart documentation for additional options and properties.
