1. Deploy the tyk-operator helm chart on Rancher

    TypeScript

    To deploy the tyk-operator Helm chart on a Rancher-managed Kubernetes cluster, you need to perform a series of tasks.

    1. Prerequisites: Ensure that you have a Rancher-managed Kubernetes cluster set up and that you have access to it.

    2. Installing the Pulumi CLI: If you haven't already installed Pulumi, visit the Pulumi Installation Guide.

    3. Setting Up Your Pulumi Project: You will need to create a new Pulumi project if you do not already have one. Use pulumi new command and choose an appropriate template to get started.

    4. Configuring Access to Rancher: You must have configured your Pulumi environment with access to your Rancher instance. This typically involves setting environment variables or the ~/.kube/config file with the credentials to interact with your Rancher cluster.

    5. Installing the Rancher2 Pulumi Provider: To work with Rancher2 resources, install the Rancher2 provider plugin for Pulumi using the Pulumi CLI: pulumi plugin install resource rancher2 <version>. Ensure you install the version that is compatible with your Pulumi SDK version.

    Let's assume you have the prerequisites in place—Now I will show you a TypeScript program that uses Pulumi to deploy the tyk-operator Helm chart on a Rancher-managed Kubernetes cluster.

    The following program utilizes the @pulumi/rancher2 package to interact with your Rancher instance and deploy a Helm chart:

    import * as rancher2 from "@pulumi/rancher2"; import * as kubernetes from "@pulumi/kubernetes"; // First, create a Rancher2 provider instance with the required configurations. const rancher2Provider = new rancher2.Provider("myRancher", { // Configuration options for the provider. }); // Now we need to reference the Kubernetes cluster managed by Rancher where we want to deploy the `tyk-operator` // Retrieve the cluster information using the rancher2.Cluster resource if you need to reference an existing cluster. const cluster = rancher2.getCluster({ name: "my-rancher-cluster", }, { provider: rancher2Provider }); // Next, create a Kubernetes provider instance which knows how to communicate with the Rancher Kubernetes cluster. const k8sProvider = new kubernetes.Provider("myK8sProvider", { kubeconfig: cluster.kubeConfig, }); // A Helm chart for the tyk-operator can be deployed using the kubernetes.helm.v3.Chart resource. const tykOperatorChart = new kubernetes.helm.v3.Chart("tyk-operator", { chart: "tyk-operator", version: "0.6.0", // Specify the version of the tyk-operator Helm chart. fetchOpts: { repo: "https://helm.tyk.io/public/helm/charts/", // Replace with the correct Helm chart repository URL. }, }, { provider: k8sProvider }); // Use stack exports to capture output variables you might be interested in. export const tykOperatorChartName = tykOperatorChart.metadata.apply(m => m.name); export const tykOperatorChartVersion = tykOperatorChart.chart.apply(c => c.version);

    Here’s what each part of the program does:

    • We import the required Pulumi packages for deploying and managing resources in Rancher2 and for general Kubernetes resources, including Helm charts.

    • We create a new Pulumi provider for Rancher, which allows us to interact with the Rancher API. Replace the placeholder in rancher2.Provider with the appropriate configuration for your Rancher instance.

    • We then retrieve the Kubernetes cluster information from a Rancher-managed cluster that we aim to deploy the tyk-operator on.

    • We set up another provider, this time for Kubernetes, which uses the kubeconfig data retrieved from the previous step.

    • With this Kubernetes provider, we can now declare a new Helm chart resource, specifying the name, version, and repository of the tyk-operator chart.

    • Lastly, we export two stack outputs: the name and version of the deployed tyk-operator Helm chart.

    Please replace "my-rancher-cluster" and other placeholder strings with the appropriate values for your setup.

    Note that Rancher-related Pulumi resources may not directly cover all Kubernetes operations. For complete Kubernetes management, including deploying Helm charts like tyk-operator, you would leverage the Pulumi Kubernetes Provider as shown above, which should work seamlessly with clusters managed by Rancher.
