1. Deploy the fluentbit-resource helm chart on Kubernetes


    To deploy the fluentbit Helm chart on a Kubernetes cluster using Pulumi, you will first need to have a Kubernetes cluster set up and accessible. In this example, I assume you have a configured kubeconfig file that provides access to your cluster.

    Pulumi provides a Helm Chart resource as part of its Kubernetes provider, which allows you to deploy Helm charts. The Chart resource from the Pulumi Kubernetes provider will be used to deploy the fluentbit chart. This resource requires several parameters:

    • chart: The name of the Helm chart to deploy.
    • version: The version of the Helm chart to use.
    • fetchOpts: (Optional) The repository options if the chart is not from the stable repository.
    • namespace: The Kubernetes namespace to deploy the chart. If not provided, it defaults to the default namespace.

    Here is a TypeScript program that creates a Helm chart deployment for fluentbit in a designated namespace:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes Namespace const ns = new k8s.core.v1.Namespace("fluentbit-ns", { metadata: { // Replace this name with the desired namespace name name: "fluentbit", }, }); // Deploy the Fluent Bit Helm Chart in the created namespace const fluentbitChart = new k8s.helm.v3.Chart("fluentbit", { chart: "fluent-bit", // Specify the version of the Helm chart you wish to deploy version: "0.15.0", // Use the appropriate chart version // If the chart is not available in the stable repository, specify the repo URL fetchOpts: { repo: "https://fluent.github.io/helm-charts" }, namespace: ns.metadata.name, // You can specify additional values to customize the deployment // values: { ... }, }, {dependsOn: ns}); // Export the Namespace name export const namespaceName = ns.metadata.name; // Export the Chart name export const chartName = fluentbitChart.metadata.name;

    In the code above:

    • We start by importing the Pulumi Kubernetes package.
    • We create a Kubernetes namespace called fluentbit-ns for organizational purposes, which will contain our fluent-bit deployment.
    • We deploy the Helm chart by creating an instance of Chart. We specify the fluent-bit chart and set the version to 0.15.0 (note: you should specify the version of the Helm chart you want to deploy). The fetchOpts parameter contains the repository URL from where to fetch the chart; in this case, it's the fluent-bit repository.
    • We use the namespace parameter to specify that our Helm chart should be deployed within the fluentbit namespace we created earlier.
    • The fetchOpts parameter is used because the fluent-bit chart is not part of the default repositories available in Helm. The repository URL provided in repo needs to be the one where the fluent-bit chart is stored.
    • Two Pulumi stack exports are provided, which will give you the namespace name and the chart deployment name after Pulumi applies the configuration. This is useful for tracking and managing your deployments.

    To run this program, save it as index.ts in a new Pulumi project. Ensure you have Pulumi installed and configured to connect to your Kubernetes cluster.

    Please replace the placeholder version with the actual version of the Fluent Bit chart you want to deploy. You can find Helm chart versions on the fluent-bit Helm repository or the artifact hub.

    Then, execute the following commands:

    1. To install the necessary Pulumi packages, run: npm install
    2. To create the resources with Pulumi, run: pulumi up

    Pulumi will print out the planned changes, ask for confirmation, and then proceed with the deployment if confirmed. After the deployment is finished, you can see the Fluent Bit logs and monitor your Kubernetes cluster.
