1. Deploy the ibm-ssp-engine helm chart on AWS EKS

    TypeScript

    To deploy the ibm-ssp-engine helm chart on AWS EKS using Pulumi, we will follow these steps:

    1. Create an EKS cluster using the aws.eks.Cluster resource. It represents an EKS cluster in AWS and will be the foundation for deploying the Helm chart.
    2. Set up an EKS role using the aws-iam.EKSRole resource. This role will define the permissions needed by EKS to manage resources on behalf of the Helm chart.
    3. Install the Helm chart using the kubernetes.helm.sh/v3.Chart resource from @pulumi/kubernetes. This resource enables us to manage Helm chart releases as part of our Pulumi infrastructure code.

    Here's the TypeScript program that describes these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as aws from "@pulumi/aws"; import * as awsx from "@pulumi/awsx"; import * as eks from "@pulumi/eks"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create an EKS cluster const cluster = new eks.Cluster("eks-cluster", { // Add desired configurations for the cluster }); // Step 2: Set up an IAM role for EKS const eksRole = new aws.iam.Role("eksRole", { assumeRolePolicy: aws.iam.assumeRolePolicyForPrincipal({ Service: "eks.amazonaws.com", }), }); new aws.iam.RolePolicyAttachment("eksPolicyAttachment", { role: eksRole, policyArn: aws.iam.ManagedPolicy.AmazonEKSClusterPolicy, }); new aws.iam.RolePolicyAttachment("eksVPCCNIPolicyAttachment", { role: eksRole, policyArn: aws.iam.ManagedPolicy.AmazonEKS_CNI_Policy, }); // Ensure that the EKS cluster is up and running before installing Helm charts const kubeconfig = pulumi. all([cluster.eksCluster.name, cluster.eksCluster.endpoint, cluster.eksCluster.certificateAuthority, eksRole.arn]) .apply(([name, endpoint, certificateAuthority, roleArn]) => { return `apiVersion: v1 clusters: - cluster: server: ${endpoint} certificate-authority-data: ${certificateAuthority.data} name: ${name} contexts: - context: cluster: ${name} user: ${name} name: ${name}-${roleArn} current-context: ${name}-${roleArn} kind: Config preferences: {} users: - name: ${name}-${roleArn} user: exec: apiVersion: client.authentication.k8s.io/v1alpha1 command: aws args: - "eks" - "get-token" - "--cluster-name" - "${name}" # env: null # If you have a AWS_PROFILE environment variable, uncomment and configure # this section with # - name: AWS_PROFILE # value: "<profileName>" `; }); // Step 3: Install the ibm-ssp-engine Helm chart const helmChart = new kubernetes.helm.v3.Chart("ibm-ssp-engine", { chart: "ibm-ssp-engine", // Specify the version of the chart if necessary // version: "<chart-version>", // Configure your Helm chart values here // values: {...}, }, { provider: new kubernetes.Provider("k8s-provider", { kubeconfig }) }); // Export the cluster's kubeconfig export const kubeconfigOutput = kubeconfig;

    Explanation:

    • aws.eks.Cluster (docs): This resource is used to create and manage an EKS cluster. You can specify configurations such as the VPC configuration, cluster version, node groups, and more.

    • aws-iam.EKSRole (docs): Represents the IAM role that will be used by the EKS cluster. This role has policies attached that allow EKS to manage AWS resources.

    • kubernetes.helm.sh/v3.Chart (docs): This resource allows us to deploy a Helm chart. We specify which chart to deploy, its version, and the configuration values. It also needs a Kubernetes provider to be specified, which includes the kubeconfig for the newly created EKS cluster.

    The kubeconfig output from this program contains the Kubernetes configuration necessary for clients to connect to the new EKS cluster. You can save this to a file and use it with kubectl or other Kubernetes tools.

    Remember that to deploy EKS and Helm charts successfully, you need appropriate AWS credentials and permissions, as well as Helm and Kubernetes tools configured locally or within your CI/CD system. This program assumes that you have already set up the Pulumi environment and AWS provider credentials.

    Also, note that you should pass your specific configurations such as node size, desired capacity, IAM permissions, and Helm chart values for actual usage. The placeholders need to be replaced with your desired settings and resource names.
