1. Deploy the fluentd-kubernetes helm chart on AWS EKS

    TypeScript

    To deploy the fluentd-kubernetes Helm chart on an AWS EKS cluster, we'll need to follow these steps:

    1. Provision an EKS cluster: We will use the aws.eks.Cluster resource to create an Amazon EKS cluster. You will need an IAM role that EKS can assume to create AWS resources for Kubernetes.

    2. Configure Helm and Kubernetes provider: After the EKS cluster creation, we need to configure the Helm and Kubernetes provider which will allow Pulumi to interact with the Kubernetes cluster and deploy Helm charts.

    3. Deploy the Helm chart: With the providers configured, we will use the kubernetes.helm.v3.Chart resource to deploy the fluentd-kubernetes Helm chart into our EKS cluster.

    Let's start with the TypeScript program which encapsulates these steps:

    import * as aws from "@pulumi/aws"; 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"); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes provider instance that uses our EKS cluster from above. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the fluentd-kubernetes Helm chart using the Kubernetes provider instance. const fluentdChart = new k8s.helm.v3.Chart("fluentd", { chart: "fluentd", version: "<chart version>", // replace with the chart version e.g. "2.0.5" namespace: "kube-system", // specify the namespace if needed fetchOpts: { // specify the repository if it's not a stable repository repo: "https://fluent.github.io/helm-charts", }, }, { provider: k8sProvider }); // Optionally, you can also output properties of the deployed Helm Chart. export const fluentdChartResources = fluentdChart.resources;

    This program does the following:

    • Imports the necessary Pulumi libraries for AWS EKS and Kubernetes.
    • Sets up a new AWS EKS cluster using Pulumi's EKS component (eks.Cluster). It specifies a cluster and exports the necessary kubeconfig which contains credentials for accessing the Kubernetes cluster.
    • Establishes a Pulumi Kubernetes provider. This will use credentials from kubeconfig to communicate with the Kubernetes cluster.
    • Deploys the fluentd-kubernetes Helm chart to the EKS cluster using the previously established Kubernetes provider. The Helm chart version, namespace, and repository URL are specified in the configuration, and these parameters can be adjusted to suit your needs.

    Exports

    • kubeconfig: This output comprises the configuration required to connect to your EKS cluster with kubectl and other Kubernetes tooling.
    • fluentdChartResources: This optional export lists all Kubernetes resources created as part of the Helm chart deployment, enabling you to reference any of these resources in other parts of your Pulumi program.

    Running your Pulumi Program

    To apply this Pulumi code, simply use the Pulumi CLI:

    1. Save the code to a file named index.ts.
    2. Run pulumi up in your shell.

    This will prompt Pulumi to provision the resources as specified in your code. Please note that you would need Pulumi installed and configured with the AWS credentials for this to work.

    Feel free to adjust any values or add more configuration options according to what you need for your deployment. The version in the Helm chart deployment should correspond to the version of fluentd-kubernetes Helm chart you want to deploy. Make sure you have the right access permissions and AWS credentials configured for Pulumi before running the program.
