1. Deploy the fluentd-operator helm chart on Rancher

    TypeScript

    To deploy the fluentd-operator helm chart on a Rancher-managed Kubernetes cluster using Pulumi, we will use the rancher2 package. With this package, you can interact with Rancher 2.x features, such as managing clusters, workloads, and Helm chart applications.

    First, we'll create a Pulumi program to:

    • Set up a helm chart resource targeting our Rancher cluster
    • Deploy the fluentd-operator Helm chart into the desired namespace within the Rancher-managed cluster

    Here's a step-by-step guide on how to do this in TypeScript:

    1. Setting up the Pulumi Project: Before writing the code, make sure you have installed the Pulumi CLI and initialized a Pulumi project. If you haven't done this yet, please follow the Getting Started guide from Pulumi's documentation.

    2. Installing rancher2 Provider: Your Pulumi program requires the rancher2 provider to interact with Rancher's API. You add the provider by importing it into your program.

    3. Creating a Rancher Cluster Resource: Although the code below assumes that you already have a Rancher-managed cluster up and running, the rancher2 package provides resources for cluster management if you need to create one programmatically.

    4. Deploying Helm Chart: We will use the rancher2.CatalogV2 resource to add the repository that contains the fluentd-operator chart. Then, we'll deploy the chart using the rancher2.AppV2 resource. The chart's values can be customized as needed.

    Below is the Pulumi program in TypeScript:

    import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Provide the Rancher cluster ID where you want to deploy the Helm chart const clusterId = "<your-rancher-cluster-id>"; // Add the Helm chart repository as a Catalog in Rancher using the Fluentd repository URL const catalog = new rancher2.CatalogV2("fluentd-operator-repo", { clusterId: clusterId, url: "https://charts.fluentd-operator.dev/helm/", gitBranch: "main", // Specify the branch if the repository is a Git repository }); // Use the catalog to deploy the Fluentd-Operator Helm chart const fluentdOperatorChart = new rancher2.AppV2("fluentd-operator", { clusterId: clusterId, namespace: "fluentd-operator", // Replace this with the namespace in which you want the chart to be deployed repoName: catalog.name, chartName: "fluentd-operator", values: { /* specify any customized values for the Helm chart */ }, }); // Export the name of the cluster where the fluentd-operator is deployed. export const fluentdOperatorClusterName = clusterId;

    Make sure to replace <your-rancher-cluster-id> with the actual ID of your Rancher-managed Kubernetes cluster.

    Explanation:

    • We import the rancher2 package, which allows us to interact with Rancher 2.x clusters.
    • We create a new rancher2.CatalogV2 resource, which is equivalent to adding a new Helm chart repository in the Rancher UI.
    • We then declare a rancher2.AppV2 resource to deploy the fluentd-operator chart from the added catalog. This is similar to deploying a Helm chart from the Rancher UI or using Helm directly.

    To launch this Pulumi program, run pulumi up in the terminal from the directory containing your Pulumi project. Pulumi CLI will preview the actions and ask for your confirmation before applying the changes.

    Remember, this code assumes you already have a Rancher cluster set up. Managing the lifecycle of a Rancher-managed cluster programmatically is also possible with Pulumi and would involve additional resources from the rancher2 package.

    If you need further customization of the Helm chart deployment, you can adjust the values field in the rancher2.AppV2 resource to match the appropriate chart values you require. The Pulumi program will take care of the deployment details, communicating with Rancher via its API to apply the changes.
