1. Deploy the webpagetest-agent helm chart on Rancher

    TypeScript

    To deploy the webpagetest-agent helm chart on a Kubernetes cluster managed by Rancher, we'll need to go through a few steps:

    1. Set up a Kubernetes Cluster: Ensure you have a Kubernetes cluster managed by Rancher. While the code for creating a new Rancher cluster is beyond the scope of this task, Pulumi's rancher2 package includes a Cluster resource that can be used to manage clusters within Rancher.

    2. Install and Configure the Rancher2 Provider: Use the rancher2 Pulumi provider to interact with Rancher. This will require credentials for authenticating with the Rancher API. You can set these up using the Pulumi configuration system or environment variables.

    3. Use the Helm Chart: After setting up the Kubernetes cluster and the provider, we'll deploy the webpagetest-agent chart. If webpagetest-agent is available in the helm registry, we can directly install it using Pulumi's helm provider; otherwise, we'd need to add the helm repository that contains the chart first.

    4. Deploy using Pulumi: Define a Pulumi stack and specify the configurations for deploying the helm chart into your Kubernetes cluster managed by Rancher.

    Let's go through these steps in code. Below is a TypeScript program you can use as a Pulumi stack. This program assumes that you already have a Kubernetes cluster set up and managed via a Rancher instance.

    Note: Before running the following Pulumi program, ensure you have set up your Pulumi and Kubernetes environment correctly, and you have configured Rancher API access correctly.

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; // Create a new Rancher2 provider instance. const rancher2Provider = new rancher2.Provider("rancher-provider", { apiUrl: "https://<RANCHER-HOST>/v3", accessKey: "<RANCHER-ACCESS-KEY>", secretKey: "<RANCHER-SECRET-KEY>", }); // It is assumed you have a cluster already set up and you will get its ID // The "clusterId" can be retrieved from Rancher UI or via Rancher API. const clusterId = "<RANCHER-CLUSTER-ID>"; // Create a Kubernetes provider instance using the cluster information from Rancher. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: rancher2.Cluster.get("cluster", clusterId, { provider: rancher2Provider }).kubeConfig, }); // If the 'webpagetest-agent' helm chart is not part of the default helm repo, // you might need to specify the helm chart repository. Uncomment the following // lines and substitute the placeholder values to add a repository. /* const webPageTestRepo = new k8s.helm.v3.Repository("web-page-test-repo", { name: "webpagetest", url: "https://<webpagetest-agent-chart-repo>", }, { provider: k8sProvider }); */ // Deploy the 'webpagetest-agent' helm chart into the Kubernetes cluster. const webPageTestAgentChart = new k8s.helm.v3.Chart("webpagetest-agent-chart", { chart: "webpagetest-agent", // Specify the repository name if you have added a custom helm repository. // If the chart is part of the default stable repo, this is not needed. // repositoryOpts: { // repo: webPageTestRepo.name, // }, // Optionally, specify the chart version and values here. // version: "x.y.z", // values: { ... }, }, { provider: k8sProvider }); // Export the chart name of the deployed helm chart. export const chartName = webPageTestAgentChart.metadata.apply(metadata => metadata.name);

    Explanation:

    • Rancher2 Provider: This configures the Pulumi provider to interact with the Rancher API. Replace <RANCHER-HOST>, <RANCHER-ACCESS-KEY>, and <RANCHER-SECRET-KEY> with your Rancher server URL and API credentials.

    • Cluster Information: The clusterId is the unique identifier of your Kubernetes cluster within Rancher. Replace <RANCHER-CLUSTER-ID> with your actual cluster ID.

    • Kubernetes Provider: This configures the Pulumi provider to interact with the Kubernetes cluster managed by Rancher. We retrieve the kubeconfig from the rancher2.Cluster which allows Pulumi to connect with the cluster.

    • Helm Chart Repository: This is commented out because it's only necessary if webpagetest-agent is not part of the default repositories. If you have a specific Helm repository, uncomment this section and replace <webpagetest-agent-chart-repo> with your repository URL.

    • Helm Chart: This component is responsible for deploying the webpagetest-agent chart to your Kubernetes cluster. You can specify version and chart values if needed, which allows you to configure the webpagetest-agent to fit your requirements.

    • Exports: This example exports the name of the Helm chart deployment, making it visible outside of Pulumi for further reference.

    This Pulumi stack can be run using the Pulumi CLI. Save this script with a .ts extension, ensure you have the right dependencies installed in your package.json, and execute pulumi up to preview and deploy the changes. Remember to swap out placeholder values with real information from your environment.
