1. Deploy the msb helm chart on Linode Kubernetes Engine

    TypeScript

    To deploy a Helm chart on Linode Kubernetes Engine using Pulumi, we will use the kubernetes package, which provides the necessary resources to interact with a Kubernetes cluster and deploy Helm charts.

    First, you will need to set up a Kubernetes cluster on Linode. Assuming you've done that and have your Kubernetes config file ready to be used by Pulumi, we can proceed with creating a Pulumi program.

    Below is a Pulumi program written in TypeScript, which will deploy a Helm chart named msb (my-service-broker, abbreviated as msb) onto a Linode Kubernetes Engine cluster. Helm is a package manager for Kubernetes, which simplifies the deployment and management of applications on Kubernetes clusters.

    The program is structured into four main parts:

    1. Import necessary modules.
    2. Create a provider configuration for Kubernetes.
    3. Define the Helm chart you wish to deploy.
    4. (Optional) Export outputs that may be useful for you.

    Make sure to install the required Pulumi dependencies using your package manager (e.g., npm or yarn) before running the Pulumi program.

    Here's the detailed program structure with explanations:

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Replace the placeholder values with your actual cluster configuration const kubeconfig = `...`; // Your Linode Kubernetes Engine kubeconfig content as a string // Create a Kubernetes provider instance using the kubeconfig. const provider = new k8s.Provider('linode-k8s', { kubeconfig: kubeconfig, }); // Define the Helm chart deployment. Here, we are deploying a chart named 'msb'. // You may need to specify the exact 'chart' name, the 'version', and any 'values' // that you want to override the defaults as specified in the Helm chart. const msbChart = new k8s.helm.v3.Chart('msb', { chart: 'msb', // The name of the chart, change it to your specific chart name version: '1.0.0', // The version of the chart fetchOpts: { repo: 'http://charts.mycompany.com/', // The repository where your Helm chart is located }, values: { serviceType: 'LoadBalancer', // Example of overriding a value in the chart (customize as needed) // Add more values here based on your Helm chart's configurable options }, }, { provider: provider }); // Optionally, you may want to export the resulting service endpoint export const serviceEndpoint = msbChart.getResourceProperty('v1/Service', 'msb-service', 'status');

    Save the above program in a .ts file (for example, deployMsbChart.ts) within your Pulumi project directory.

    To create a Pulumi project and run this code:

    1. Initialize a Pulumi project and select the TypeScript language.
    2. Install @pulumi/pulumi and @pulumi/kubernetes packages using npm.
    3. Replace the placeholders in the code with the actual values specific to your Helm chart and Linode Kubernetes Engine cluster.
    4. Run pulumi up to deploy your Helm chart to the cluster.

    The kubeconfig is required to access your Kubernetes cluster on Linode. Ensure to replace the kubeconfig placeholder with the content of your kubeconfig file.

    Note that you may need to change the Helm chart name (msb) to the actual chart name you wish to deploy, and adjust the values object to contain the configuration settings that are appropriate for your specific Helm chart. The repo property within fetchOpts should point to the Helm repository where your chart is hosted.

    By executing this Pulumi program, it will use the provided kubeconfig to authenticate with your Kubernetes cluster and deploy the specified Helm chart along with any overrides you've provided in the values object. After the deployment, if you have specified an export for the service endpoint, you can use the pulumi stack output serviceEndpoint command to retrieve the service status, including LoadBalancer IP or hostname if applicable.
