1. Deploy the quay helm chart on Linode Kubernetes Engine


    To deploy the Quay Helm chart on a Linode Kubernetes Engine (LKE) cluster using Pulumi and the Kubernetes provider, you need to follow several steps. First, you'll need to set up the Kubernetes provider to point to your LKE cluster. This typically involves obtaining the kubeconfig file from Linode for your Kubernetes cluster.

    Once you have the kubeconfig configured, you can proceed with defining the Helm chart deployment in your Pulumi program. We will be using the kubernetes.helm.v3.Chart resource to deploy the Quay Helm chart. It will require specifying the chart name, and optionally the chart version, repository, and any custom values you wish to apply to the deployment.

    Let's walk through the TypeScript Pulumi program that carries out these steps:

    1. Import the necessary packages.
    2. Create a Kubernetes provider instance, pointing it to your LKE cluster.
    3. Define a Helm Chart resource for deploying Quay.
    4. Export any necessary stack outputs.

    Here's the complete Pulumi program in TypeScript:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // For this example, we assume that you already have a kubeconfig file // for your Linode Kubernetes cluster. The `KUBECONFIG` environment variable // should be set to the path of this kubeconfig file. // Initialize a Kubernetes provider with the kubeconfig from the environment variable. const provider = new k8s.Provider("lke-k8s", { kubeconfig: process.env.KUBECONFIG, }); // Now, you will deploy Quay using a Helm chart. You need the chart name, repository, and // optionally the version of the chart you are deploying. If you have any custom values // you would like to override in the chart, you can specify them in the `values` field. // Create a Helm Chart for Quay. const quayChart = new k8s.helm.v3.Chart("quay", { chart: "quay", version: "3.5.0", // Specify the version of Quay's Helm chart you wish to deploy. fetchOpts: { repo: "https://quay.github.io/charts/", // This is the repository where the Quay Helm chart is located. }, }, { provider: provider }); // If you have outputs from the chart that you would like to export, you can do so. // For example, if you want to export the external IP address of the Quay service (if it is a LoadBalancer service), // you may use the following code, adjusting the resource names and properties according to your chart's outputs // (please check the specific Helm chart documentation for details on the output values you can expect). const quayService = quayChart.getResource("v1/Service", "quay-quay-app"); export const quayServiceIP = quayService.status.apply(status => status.loadBalancer.ingress[0].ip); // After running `pulumi up` all resources above will be provisioned.

    This program does the following:

    • It creates a new instance of a Kubernetes provider that Pulumi will use to communicate with your Linode Kubernetes Engine. This provider is configured with a kubeconfig file that you must provide via an environment variable (KUBECONFIG).
    • It then declares a Helm chart resource for Quay, specifying the chart name, version, and repository URL. This definition lets Pulumi know which Helm chart to deploy and how to configure it.
    • Optionally, if you wish to export the public IP address of your Quay service (likely if the service type is LoadBalancer), the last part of the code tries to retrieve the service resource created by the Helm chart and export its IP.

    With this Pulumi program, you can deploy the Quay Helm chart to your Linode Kubernetes cluster. Make sure to adjust the chart version and values as per your needs based on the Quay Helm chart you are using. If you're using a different Helm chart repository or version for Quay, modify repo and version accordingly.

    After writing the above code in a file (e.g., index.ts), run it by executing the following commands in your terminal:

    pulumi stack init my-quay-deployment pulumi up

    The first command initializes a new stack for your deployment (you can name it as you wish), and the second command provisions the resources defined in your TypeScript program. Ensure your Pulumi CLI is installed and configured with the appropriate access credentials for Linode.
