1. Deploy the rbacmanager helm chart on Rancher


    In order to deploy the rbacmanager Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you would use the rancher2 package. This package allows you to interact with Rancher resources. However, as of the current Pulumi registry, there's no high-level abstraction in the Pulumi rancher2 package that directly represents Helm chart deployments.

    Instead, you would typically use the helm.v3 package in Pulumi, which offers resources for deploying Helm charts. Unfortunately, using helm.v3 directly with Rancher is non-standard because Rancher has an integrated Helm controller that manages chart deployments through its own API, which is different from Helm's typical Kubernetes integration.

    Despite this, I'll show you a Pulumi program written in TypeScript that would theoretically deploy a Helm chart using the helm.v3 package and assume a properly configured Kubernetes cluster by Rancher is the target. Please be aware that additional steps might be required if Rancher's custom Helm chart installation process or RBAC needs are not covered by this example.

    I'll start with a brief explanation of the resources and flow:

    1. Helm Chart: This resource is a representation of a Helm chart. In this case, rbacmanager will be deployed. The chart will be fetched from the specified repository.
    2. Kubernetes Provider: Pulumi uses providers to interact with cloud services. The Kubernetes provider will be used to deploy the Helm chart to a Kubernetes cluster managed by Rancher.

    Here's a detailed Pulumi TypeScript program that deploys the rbacmanager Helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes provider instance that targets your Rancher-managed cluster. const rancherK8sProvider = new k8s.Provider("rancherK8sProvider", { kubeconfig: "<YOUR_KUBECONFIG>", // This should be the kubeconfig file content for Rancher-managed cluster. }); // Deploy the rbacmanager Helm chart using the helm.v3.Chart resource. const rbacManagerChart = new k8s.helm.v3.Chart("rbacmanager", { // The repository where the rbacmanager chart is located. repo: "rbac-manager", // The name of the chart. chart: "rbacmanager", // Version number of the chart to deploy, it's good to specify this to avoid unexpected updates. version: "<CHART_VERSION>", // Namespace where the chart should be deployed, if not specified, it's deployed in the default namespace. namespace: "kube-system", }, { provider: rancherK8sProvider }); // Optionally, you can export the status of the deployment. export const rbacManagerStatus = rbacManagerChart.status;

    Please replace <YOUR_KUBECONFIG> with the actual kubeconfig content that allows Pulumi to interact with your Rancher-managed Kubernetes cluster. Moreover, replace <CHART_VERSION> with the version of the rbacmanager Helm chart that you want to deploy.

    Be sure to check if you need any specific configurations for the rbacmanager chart itself, such as custom values which you can specify in the values parameter of the Chart resource.

    You might need to adjust the namespace or include the values option if there are configurations specific to rbacmanager that you need to set.

    After writing this Pulumi program, run it with Pulumi CLI commands such as pulumi up to initiate the deployment process.

    Please note that deploying Helm charts to a Rancher-managed Kubernetes cluster might require using Rancher's own Helm chart installation mechanism through its API or UI for seamless integration, especially when considering Rancher's RBAC and project-based organization. While the above example demonstrates the Helm chart deployment using Pulumi, ensure that you're also aligning with Rancher's practices for managing resources in your clusters.
