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


    To deploy the fluentd-papertrail Helm chart on an Amazon EKS cluster, we will perform the following steps:

    1. Create an EKS cluster: Leveraging awsx package to create an EKS cluster with a managed node group. The awsx package provides a higher-level abstraction over the aws package, simplifying the cluster creation process.

    2. Deploy the fluentd-papertrail Helm chart: Once we have an EKS cluster, we will use the kubernetes package to deploy the Helm chart to the cluster.

    Here's a Pulumi program written in TypeScript that demonstrates these steps. Please read the comments inside the code for a deeper understanding of each step and adjust property values like region, instanceType, etc., according to your preferences and needs.

    import * as awsx from "@pulumi/awsx"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an EKS cluster // We are using `awsx` for a simplified cluster setup. For production, you might need to configure additional options such as VPC, IAM roles, etc. const cluster = new eks.Cluster("papertrail-cluster", { desiredCapacity: 2, // Desired number of worker nodes. minSize: 1, // Minimum number of worker nodes. maxSize: 3, // Maximum number of worker nodes. instanceType: "t2.medium", // Instance size for the worker nodes. }); // Export the cluster's kubeconfig which can be used with kubectl to communicate with the cluster. export const kubeconfig = cluster.kubeconfig; // Step 2: Deploy the fluentd-papertrail Helm chart // Using the `k8s` provider to deploy Helm charts, which abstracts away the Helm CLI tool. const fluentdPapertrailChart = new k8s.helm.v3.Chart("fluentd-papertrail", { chart: "fluentd", version: "YOUR_CHART_VERSION", // Specify the chart version you want to deploy. fetchOpts: { repo: "https://YOUR_HELM_REPO_URL", // Use the correct Helm repository URL for the fluentd-papertrail chart. }, values: { // Specify the chart values here, for example: papertrail: { enabled: true, destination: "YOUR_PAPERTRAIL_DESTINATION", // Replace with your actual Papertrail log destination. }, // ... other values ... }, }, { provider: cluster.provider }); // It's crucial to set the provider with the EKS cluster to ensure the Helm chart is deployed to the correct Kubernetes cluster.

    In this program:

    • We start by importing the required Pulumi packages.
    • We create an EKS cluster named papertrail-cluster using the eks.Cluster class from the @pulumi/eks package. In the real world, you would likely need to configure additional properties such as custom subnets, IAM roles, security groups, etc., depending on your infrastructure requirements.
    • Next, we deploy the fluentd-papertrail Helm chart using the @pulumi/kubernetes package. The k8s.helm.v3.Chart class facilitates deploying Helm charts in a declarative manner using Pulumi.
    • We specify the Helm chart repository and version, as well as configuration values specifically for the fluentd-papertrail chart (like enabling Papertrail and setting the log destination). The actual values will depend on your particular setup and the configuration options provided by the fluentd-papertrail Helm chart. Refer to the chart's documentation for detailed configuration parameters.
    • Finally, we export the cluster's kubeconfig, which can be used with kubectl or other Kubernetes tools to interact with the cluster.

    Before running this program, ensure that you have Pulumi installed and configured with your AWS credentials. You also need to replace "YOUR_CHART_VERSION" and "https://YOUR_HELM_REPO_URL" with the specific Helm chart version and the repository URL for fluentd-papertrail. Replace "YOUR_PAPERTRAIL_DESTINATION" with your actual Papertrail destination.

    To run the Pulumi program:

    1. Save the code to a file, for example, index.ts.
    2. Ensure you have the required Pulumi stack and AWS environment configured.
    3. Run pulumi up from the command line in the same directory as your index.ts file.
    4. Pulumi will print out the planned actions and ask for confirmation before making any changes to your cloud resources.
