1. Deploy the cloudbees-sidecar-injector helm chart on Linode Kubernetes Engine


    To deploy the cloudbees-sidecar-injector Helm chart on Linode Kubernetes Engine using Pulumi, you need to write a Pulumi program that will perform several steps:

    1. Establish a connection to your Kubernetes cluster on Linode.
    2. Use the Helm Chart resource to deploy cloudbees-sidecar-injector.

    First, ensure you have Pulumi installed and set up with your Linode API token and your Kubernetes cluster's configuration. This guide assumes you have already provisioned a Linode Kubernetes Engine (LKE) cluster and have the kubeconfig file that allows you to communicate with your Kubernetes cluster. You should set Pulumi to use this kubeconfig file when deploying resources to your cluster.

    Below is the TypeScript program that deploys the cloudbees-sidecar-injector Helm chart using Pulumi:

    import * as k8s from "@pulumi/kubernetes"; // The name of the Linode Kubernetes cluster as you've labeled it. const clusterName = "my-lke-cluster"; // Load your Kubeconfig file that Linode provides for your Kubernetes cluster. // Typically, this file is located at `~/.kube/config`, or you might have a custom path. const kubeconfigFile = "<path-to-your-kubeconfig>"; // Create a Kubernetes provider instance using the kubeconfig. const provider = new k8s.Provider(clusterName, { kubeconfig: kubeconfigFile, }); // Define the Helm chart for the cloudbees-sidecar-injector. // You may need to specify the correct repository or chart version, depending on your use case. const cloudbeesSidecarInjectorChart = new k8s.helm.v3.Chart("cloudbees-sidecar-injector", { chart: "cloudbees-sidecar-injector", // Replace with the actual Helm repo URL that hosts the `cloudbees-sidecar-injector` chart. // For example, if it's in the "example-repo" at "https://charts.example.com/", use: // repo: "example-repo", // In this example, we assume the chart is already available in the Helm repositories configured in your cluster. // If this is not the case, include the `repo` option to point to the chart repository's URL. fetchOpts: { repo: "https://<helm-chart-repo-url>", // Replace with the actual Helm chart repository URL }, // If you have specific values to customize, pass in an appropriate 'values' object. values: { // ... specify your configuration values here }, }, { provider: provider }); // This ensures that Helm uses the correct Kubernetes cluster. // Export the URL to access the sidecar injector, which may involve querying the service or ingress created by the Helm chart. // This is highly dependent on the values set in the chart and might require customization based on your setup.


    • import * as k8s from "@pulumi/kubernetes";: This line imports the Kubernetes package from Pulumi, which enables you to interact with Kubernetes resources.

    • const provider = new k8s.Provider(clusterName, {...}): Before you can deploy any resources to your Kubernetes cluster, you need to create a Provider resource. This tells Pulumi how to communicate with your Kubernetes cluster by providing it with your kubeconfig data.

    • const cloudbeesSidecarInjectorChart = ...: This part of the code defines a Helm chart resource using Pulumi's Kubernetes provider. It specifies the Helm chart for the cloudbees-sidecar-injector. Note that you must replace placeholders like <path-to-your-kubeconfig> and https://<helm-chart-repo-url> with actual paths to your cluster's kubeconfig file and the Helm chart repository URL, respectively.

    • values: In Helm, values are used to customize the installation of the chart. This property allows you to specify custom configuration values that override defaults provided by the Helm chart.

    • The { provider: provider } argument: This argument ensures that Pulumi uses the Kubernetes provider you have set up for your LKE cluster to deploy the chart.

    • The fetchOpts property is used if you need Pulumi to fetch the Helm chart from a specific Helm repository. If the chart is available in the repositories pre-configured in your cluster's Helm setup, you may omit the fetchOpts property.

    After setting up the code above, run the following Pulumi commands to deploy the Helm chart:

    pulumi up

    This command will start the deployment process. Pulumi will show you a preview of the resources that will be created, and after your confirmation, it will apply the changes and deploy the Helm chart to your Linode Kubernetes cluster.
