1. Deploy the backup-operator helm chart on Linode Kubernetes Engine

    TypeScript

    Deploying a Helm chart to a Kubernetes cluster is a common task that can be accomplished with Pulumi's Kubernetes provider. To deploy the backup-operator Helm chart on the Linode Kubernetes Engine (LKE), we need to perform a few steps. First, we'll set up the necessary components to interact with Linode and the Kubernetes cluster. Then, we'll use Pulumi to deploy the Helm chart.

    Here's what we're going to do:

    1. We'll set up a new Pulumi project, configure it for TypeScript, and install the necessary dependencies.
    2. We'll obtain access to our Linode Kubernetes Engine cluster using a kubeconfig file.
    3. We'll deploy the backup-operator Helm chart to the LKE cluster using Pulumi's Chart resource from the Kubernetes provider.

    Make sure you have the following prerequisites in place before running the following code:

    • Pulumi CLI installed and set up.
    • Access to your Linode account and a Linode Kubernetes Engine cluster deployed.
    • The kubeconfig file that allows you to connect to your Linode Kubernetes Engine cluster.
    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the Kubernetes provider with access to the LKE cluster. // The kubeconfig file provides the necessary cluster access for Pulumi to deploy resources. const clusterProvider = new k8s.Provider("lkeProvider", { kubeconfig: "<YOUR_KUBECONFIG_CONTENTS>", // Replace this with the actual kubeconfig file contents. }); // Deploy the `backup-operator` Helm chart to the LKE cluster. const backupOperatorChart = new k8s.helm.v3.Chart("backup-operator", { chart: "backup-operator", // You might need to specify the Helm repository if the chart is not in the default repo. // repo: "<HELM_CHART_REPOSITORY>", // Uncomment and replace if necessary. version: "<CHART_VERSION>", // Replace with the specific chart version you want to deploy. // If the chart requires values, add them here under the `values` field. // values: { /* ... */ }, }, { provider: clusterProvider }); // Export the name of the chart, if you want to retrieve it later in your Pulumi stack. export const backupOperatorChartName = backupOperatorChart.metadata.apply(m => m.name);

    Replace <YOUR_KUBECONFIG_CONTENTS> with the contents of your kubeconfig file, <CHART_VERSION> with the version of the backup-operator chart you wish to use, and uncomment the repo field and provide the Helm repository URL if the chart isn't in the default Helm repository. The values object should be filled in with custom values for the chart if any configuration settings are necessary.

    This Pulumi program defines a Provider resource that points to your Linode Kubernetes cluster, and then deploys a Helm chart called backup-operator. The deployment uses the provider to ensure it targets the right cluster.

    To apply this Pulumi program, follow these steps:

    1. Save this TypeScript code to a file, typically index.ts in the Pulumi project directory.
    2. Run pulumi up in the terminal from the same directory as the code, which will start the deployment process.
    3. Pulumi will display a preview of the actions to be taken and ask for confirmation before proceeding. Review this information and type yes to proceed.

    When the deployment is complete, Pulumi will output any stack exports you have defined, such as the name of the Helm chart.

    Make sure to handle your kubeconfig file and any other sensitive information securely. Using Pulumi configuration to pass sensitive data is recommended for managing secrets.
