1. Deploy the tegola-vector-tiles helm chart on Linode Kubernetes Engine


    To deploy the tegola-vector-tiles Helm chart on the Linode Kubernetes Engine (LKE) using Pulumi, you'll need to perform several steps:

    1. Set up a new Linode Kubernetes Engine cluster or use an existing one.
    2. Install the Helm chart for "tegola-vector-tiles" on your Kubernetes cluster.

    Here's a Pulumi program in TypeScript that achieves these objectives:

    First, make sure you have installed Pulumi and configured it to use your Linode API token. You can follow the official Linode documentation for creating an API token and Pulumi documentation for configuring the Linode provider.

    In this program, we'll use the kubernetes Pulumi package to deploy the Helm chart. If you need the Helm chart to be customized, you can pass the necessary values in the values property.

    import * as k8s from "@pulumi/kubernetes"; // Ensure you have the correct config set up for your Linode token and cluster const linodeToken = "<YOUR_LINODE_API_TOKEN>"; const clusterName = "<YOUR_CLUSTER_NAME>"; // Create a Kubernetes provider instance using the context of your Linode Kubernetes cluster const provider = new k8s.Provider("lke-provider", { kubeconfig: yourLkeClusterKubeConfig(), }); // Function to fetch kubeconfig from Linode API function yourLkeClusterKubeConfig(): string { // Normally, you would use the Linode API to get the kubeconfig for your cluster. // This is a placeholder function, you need to replace this with the actual method // that retrieves the kubeconfig. return `apiVersion: v1 clusters: - cluster: certificate-authority-data: <cert-data> server: https://<cluster-endpoint> name: ${clusterName} contexts: - context: cluster: ${clusterName} user: ${clusterName}-admin name: ${clusterName} current-context: ${clusterName} kind: Config preferences: {} users: - name: ${clusterName}-admin user: token: ${linodeToken}`; } // Deploy the tegola-vector-tiles Helm chart using the Kubernetes provider const tegolaHelmChart = new k8s.helm.v3.Chart("tegola-vector-tiles", { chart: "tegola-vector-tiles", // Customize the following with the correct repository containing the tegola chart // Note: replace the 'repo' url with the actual Helm repository that hosts the tegola chart // You might need to add the chart version if necessary using the 'version' property fetchOpts:{ repo: "https://helm-repo-containing-tegola.example.com/", }, }, { provider }); // Export the public URL to access the tegola-vector-tiles application, if applicable export const tegolaPublicUrl = tegolaHelmChart.getResourceProperty("v1/Service", "tegola-vector-tiles", "status").apply(status => status.loadBalancer.ingress[0].ip);

    In the program above:

    • Replace <YOUR_LINODE_API_TOKEN> with your actual Linode API token.
    • Replace <YOUR_CLUSTER_NAME> with the name of your Linode Kubernetes cluster.
    • Replace the placeholder kubeconfig details with the actual ones for your cluster; you can retrieve this from your Linode cloud control panel.
    • The tegolaHelmChart is the instance of the Helm chart you wish to deploy, and you should replace the repo with the URL of the repository where the tegola Helm chart is hosted.
    • After deploying through Pulumi with pulumi up, you can then access tegolaPublicUrl for the service address. Note that you'll only have a public URL if the service type in the Helm chart is set to LoadBalancer and it's correctly configured on LKE.

    To apply the above resources to your Linode Kubernetes Engine, run the command pulumi up from the terminal in the directory containing this program file. This will instruct Pulumi to provision the resources as per the program described, rolling out the tegola vector tiles application on LKE.
