1. Deploy the kusk-gateway-envoyfleet helm chart on Rancher


    Deploying a Helm chart on Rancher using Pulumi involves several steps, including setting up a Pulumi project, creating a stack, and writing the necessary code to define your infrastructure.

    First, you'll need to have Pulumi installed and have access to a Rancher-managed Kubernetes cluster. Since Rancher-specific resources are not available in the Pulumi Registry Results directly, we'll be using the standard Kubernetes provider to deploy the kusk-gateway-envoyfleet Helm chart to your Rancher cluster.

    The steps below outline how you would typically proceed:

    1. Set up the Kubernetes context to point to the Rancher-managed cluster. This typically involves using the rancher CLI to log in to Rancher and then using the kubectl command to get the appropriate context and set it as the current context for kubectl.

    2. Create a new Pulumi project. You can do this by running pulumi new typescript in your CLI and following the instructions.

    3. Write the Pulumi code to set up and install the Helm chart. I'll demonstrate this in the program below where we use the @pulumi/kubernetes package to deploy to a Kubernetes cluster.

    Here's a basic Pulumi TypeScript program that deploys the requested Helm chart on a Rancher-managed Kubernetes cluster:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes provider instance that uses the current context of kubectl. // This assumes you have already set up kubectl to point to your Rancher-managed cluster. const clusterProvider = new k8s.Provider("rancher-k8s", { kubeconfig: "<RANCHER_KUBECONFIG>", // Replace with your Rancher kubeconfig data }); // Deploy the kusk-gateway-envoyfleet Helm chart. const helmChart = new k8s.helm.v3.Chart("kusk-gateway-envoyfleet", { chart: "kusk-gateway-envoyfleet", // The repository where the chart is located fetchOpts: { repo: "https://your_helm_chart_repo", // Replace with the Helm chart's repository URL }, // Specify the version of the chart you want to deploy version: "1.0.0", // Replace with the desired chart version // Override default configuration options, if necessary values: { // Specify any custom values for the chart here. }, }, { provider: clusterProvider }); // Export the name of the chart. export const helmChartName = helmChart.metadata.name;

    In this code:

    • We first import the Kubernetes package provided by Pulumi.
    • Create a Kubernetes provider that is set up with the kubeconfig for your Rancher-managed Kubernetes cluster.
    • Deploy the Helm chart by instantiating k8s.helm.v3.Chart. We specify the name of the chart (kusk-gateway-envoyfleet), the repository where the Helm chart can be found, and the desired version.
    • Optionally, if there are any specific configuration options you need to override, add them in the values object.
    • It's assumed you have already configured your Pulumi program to communicate with the Rancher Kubernetes cluster (kubeconfig is used here as a placeholder).
    • Finally, we export the name of the Helm chart as an output. This can be used to reference the chart in subsequent Pulumi programs.

    To proceed with this code, replace <RANCHER_KUBECONFIG> with your kubeconfig content. Additionally, update the repo and version in the fetchOpts to point to the correct Helm repository and chart version for kusk-gateway-envoyfleet.

    Note that the actual values for repo and chart version must be supplied according to where the kusk-gateway-envoyfleet Helm chart is hosted. Also, if additional configuration is required for your specific Rancher setup or the Helm chart itself, modify the values accordingly.

    After writing this Pulumi program, you run pulumi up to deploy to the cluster.

    Please be aware that this example assumes familiarity with Helm, Kubernetes, and Rancher. If there are additional configurations that your Rancher and Helm chart setup requires, make the necessary adjustments in the values section of the Chart resource.
