1. Deploy the speedtest-tracker helm chart on Rancher

    TypeScript

    To deploy the speedtest-tracker Helm chart on Rancher, you will need to interact with the Rancher Kubernetes environment through Pulumi. You accomplish this by setting up a Pulumi project with the appropriate cloud provider and then using the rancher2 provider.

    Here's a step-by-step explanation of what you need to do:

    1. Set up your Kubernetes Cluster: Ensure that you have a Kubernetes cluster managed by Rancher. You can use the rancher2.Cluster resource if you want to create a new Kubernetes cluster in Rancher using Pulumi.

    2. Install the Rancher2 Pulumi Provider: You will need to have the Rancher2 provider configured in your Pulumi project to interact with Rancher. You can add it by running npm install @pulumi/rancher2 in your Pulumi project directory.

    3. Configure the Rancher2 Provider: The Rancher2 provider must be configured with the necessary credentials to communicate with your Rancher instance. You'll need to have the Rancher API URL and an API token.

    4. Create a Catalog: To deploy a Helm chart, first you need to have a catalog (a Helm repository in Rancher) from which to install the chart. You can configure one if not already available using the rancher2.CatalogV2 resource.

    5. Deploy the Helm Chart: Once the catalog is added to your Rancher, you can proceed to deploy the speedtest-tracker Helm chart using the appropriate Helm chart resource in Rancher.

    Let's create a Pulumi program to deploy the speedtest-tracker Helm chart on your existing Rancher-managed Kubernetes cluster:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; // Pulumi project configuration const config = new pulumi.Config(); const rancherUrl = config.require("rancherUrl"); const rancherToken = config.requireSecret("rancherToken"); const clusterId = config.require("clusterId"); // Your Rancher Cluster ID // Configure the Rancher2 provider const rancherProvider = new rancher2.Provider("rancherProvider", { apiUrl: rancherUrl, tokenKey: rancherToken, }); // Assuming you already have a Kubernetes cluster managed by Rancher, // configure the Kubernetes provider to interact with the Rancher cluster const k8sProvider = new k8s.Provider("k8s", { kubeconfig: rancher2.getKubeConfigOutput({clusterId: clusterId}), }, { provider: rancherProvider }); // Create a Catalog (Helm repository) for the Helm chart if it does not already exist in Rancher const speedtestCatalog = new rancher2.CatalogV2("speedtestTrackerCatalog", { clusterId: clusterId, // Provide the URL to the Speedtest Tracker Helm chart repository url: "https://helm.ink/", // Replace with the actual Helm repository if different gitRepo: "<REPO_URL>", // Replace with your git repository URL gitBranch: "master", }, { provider: rancherProvider }); // Create a Namespace for the Speedtest Tracker if not already there const speedtestNamespace = new k8s.core.v1.Namespace("speedtestNamespace", { metadata: { name: "speedtest-tracker", }, }, { provider: k8sProvider }); // Deploy the Speedtest Tracker Helm chart const speedtestChart = new k8s.helm.v3.Chart("speedtestTrackerChart", { chart: "speedtest-tracker", version: "1.0.0", // Use the appropriate chart version namespace: speedtestNamespace.metadata.name, fetchOpts: { repo: "https://helm.ink/" // Speedtest Tracker Helm repository }, // Provide values for the Helm chart if necessary values: { "service": { "type": "ClusterIP" }, // ... additional configuration ... }, }, { provider: k8sProvider }); // Export the endpoint to access Speedtest Tracker export const speedtestTrackerEndpoint = pulumi.interpolate`http://${speedtestChart.getResourceProperty("v1/Service", "speedtest-tracker", "status").apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip)}`;

    In the code above:

    • We start by importing the required Pulumi packages and configuring the project with the necessary details like the Rancher URL, token, and Cluster ID.
    • We configure the Rancher2 provider by providing it with the Rancher API URL and the API token.
    • We then configure the Kubernetes provider to interact with the Rancher-managed Kubernetes cluster using the Rancher Cluster ID.
    • We add the Helm chart repository as a catalog in Rancher using the rancher2.CatalogV2 resource.
    • A Kubernetes namespace is created to house our applications. This could be created directly in Rancher or using Kubernetes tools and referenced here.
    • We deploy the chart using k8s.helm.v3.Chart. The Helm repo and any values that are used to customize the Helm chart are declared.
    • Finally, we're exporting an endpoint that can be used to access the Speedtest Tracker user interface.

    Make sure you configure your Pulumi project with the correct settings:

    • You would need a file named Pulumi.<stack-name>.yaml containing the configuration values for rancherUrl, rancherToken, and clusterId. Alternatively, you can set them using the Pulumi CLI with commands like pulumi config set rancherUrl <value>.
    • Replace URLs or any specific configurations with your actual details where placeholders are given.
    • Use the appropriate version for the speedtest-tracker Helm chart as per the catalog you're using.
    • The exported endpoint assumes a LoadBalancer service type is set up within your cluster. Adjust the resource properties according to your actual deployment. If a ClusterIP service type is used instead, you might need to set up a port-forwarding or ingress route to access the application externally.

    After setting up this Pulumi program, you can run pulumi up to deploy your Helm chart on Rancher. Make sure to review the preview of resources that Pulumi will create or modify before confirming the deployment.
