1. Deploy the ublhub helm chart on Linode Kubernetes Engine


    To deploy the ublhub Helm chart on Linode Kubernetes Engine using Pulumi, you'll need to perform the following steps:

    1. Set up a new Pulumi project and install necessary dependencies.
    2. Configure Pulumi to use the Linode provider.
    3. Create a Linode Kubernetes cluster.
    4. Deploy the ublhub Helm chart to the Linode Kubernetes cluster.

    Below you'll find a detailed Pulumi program written in TypeScript that performs these steps. Make sure you have the Pulumi CLI installed and you are logged in to your Linode account. Additionally, you need to have kubectl installed to communicate with your Kubernetes cluster and Helm if you need any chart-specific local operations.

    First, you will install the necessary dependencies:

    # Install Pulumi CLI - https://www.pulumi.com/docs/get-started/install/ # Install Node.js and npm - https://nodejs.org/en/download/ # Create a new Pulumi project pulumi new typescript # Install Linode and Kubernetes Pulumi providers npm install @pulumi/linode @pulumi/kubernetes

    And here is the TypeScript program:

    import * as pulumi from '@pulumi/pulumi'; import * as linode from '@pulumi/linode'; import * as k8s from '@pulumi/kubernetes'; // Configure your Linode project - this assumes that the Linode token is available // in the environment variable LINODE_TOKEN. const linodeProvider = new linode.Provider('linode-provider', { token: process.env.LINODE_TOKEN, }); // Create a new Linode Kubernetes cluster const cluster = new linode.LkeCluster('lke-cluster', { k8sVersion: '1.20', // Specify the version of Kubernetes you want to use region: 'us-central', label: 'lke-cluster', // A unique label for the cluster tags: ['pulumi-cluster'], pool: { count: 2, // Number of nodes in the node pool type: 'g6-standard-2', // Type of nodes to launch (this is Linode's type identifier) }, }, { provider: linodeProvider }); // Export the kubeconfig to access your cluster export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes provider using the kubeconfig from the Linode cluster const k8sProvider = new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the ublhub Helm chart const ublhubChart = new k8s.helm.v3.Chart('ublhub-chart', { chart: 'ublhub', fetchOpts: { repo: 'http://charts.ublhub.example.com/', // Replace with the actual Helm chart repo URL }, // If the chart requires values, provide them in this object // values: { // key: 'value', // }, }, { provider: k8sProvider }); // Exporting the chart name export const chartName = ublhubChart.metadata.name;


    • The linode.LkeCluster resource is used to create a Kubernetes cluster on Linode's Kubernetes Engine. You specify the Kubernetes version, region, label, and details of the node pool, such as the number of nodes and the node type.

    • After creating the cluster, we export the kubeconfig. This allows you to interact with the cluster using kubectl from your local machine if necessary.

    • We set up a k8s.Provider with the kubeconfig obtained from the Linode cluster. This provider is used to communicate with the Kubernetes cluster.

    • The ublhubChart resource represents the Helm chart that we want to deploy. You need to replace the repo URL with the actual Helm repository where the ublhub chart is hosted. If the chart requires configuration values, they can be provided in the values object.

    After writing this code into a index.ts file included in your Pulumi project, you can deploy it using the following Pulumi CLI commands:

    # To preview the deployment pulumi preview # To deploy the stack pulumi up

    Now, your ublhub Helm chart should be deployed on the Linode Kubernetes cluster. Remember to manage the resources responsibly and destroy them when they're no longer needed:

    # To destroy the resources pulumi destroy

    Always ensure you're within the project directory when executing these commands.
