1. Deploy the xos-core helm chart on Kubernetes

    TypeScript

    Deploying a Helm chart on Kubernetes using Pulumi involves creating a Pulumi project, writing the necessary code to declare the Kubernetes resources, and applying the changes with the Pulumi CLI. Below I'll guide you through the steps and provide you with a TypeScript program that deploys the xos-core Helm chart.

    Prerequisites:

    To follow along, ensure you have:

    1. Pulumi CLI installed and configured with access to a Kubernetes cluster.
    2. kubectl installed and configured with access to your Kubernetes cluster.
    3. Access to a Helm chart repository where xos-core chart is available or the chart files locally.

    Step-by-Step Guide:

    Step 1: Set Up Your Pulumi Project

    First, create a new directory for your project:

    mkdir pulumi-xos-core-deployment
cd pulumi-xos-core-deployment

    Then, create a new Pulumi project using TypeScript:

    pulumi new typescript

    You will be prompted for a project name and stack name, which you can set according to your preferences.

    Step 2: Install the Pulumi Kubernetes Package

    In the newly created Pulumi project directory, install the necessary Pulumi Kubernetes SDK:

    npm install @pulumi/kubernetes

    Step 3: Write the Deployment Code

    We will use the @pulumi/kubernetes package to deploy the xos-core Helm chart to your Kubernetes cluster. Below is a TypeScript program that performs the deployment:

    import * as k8s from "@pulumi/kubernetes";

// Name of the Helm chart, this should be changed if the chart name is different.
const chartName = "xos-core";

// Create a Kubernetes namespace for the xos-core chart.
const namespace = new k8s.core.v1.Namespace("xos-core-namespace", {
    metadata: { name: "xos-core" },
});

// Deploy xos-core using Helm chart.
const xosCoreChart = new k8s.helm.v3.Chart(chartName, {
    chart: chartName,
    version: "version-number", // Specify the version of the chart you want to deploy
    namespace: namespace.metadata.name, // Use the created namespace's name
    fetchOpts: {
        // If your chart is from a custom repository, provide the details here.
        // For example:
        // repo: "https://charts.example.com/",
    },
    // If the chart requires any custom values, define them here.
    // values: {
    //     service: {
    //         type: "LoadBalancer",
    //     },
    // },
}, { dependsOn: namespace });

// Export the Namespace name and Service's LoadBalancer external IP.
export const xosCoreNamespace = namespace.metadata.apply(metadata => metadata.name);
// If you have services exposed via LoadBalancer, you can capture and export the IPs like this:
// export const serviceExternalIp = xosCoreChart.getResourceProperty('v1/Service', 'xos-core-service', 'status').apply(status => status.loadBalancer?.ingress[0].ip);

    Make sure to replace "version-number" with the actual version number of the xos-core chart. Also, if you're using a private repo or need to specify custom values for the Helm chart, uncomment and modify the appropriate sections.

    Step 4: Deploy the Helm Chart

    After saving the above code in index.ts, deploy the Helm chart using the Pulumi CLI:

    pulumi up

    This command will preview the changes and prompt you to proceed with the deployment. Confirm the action to deploy the xos-core Helm chart to your Kubernetes cluster.

    Step 5: Check the Deployment

    Once the deployment is completed, you can verify that the Helm chart has been deployed:

    kubectl get all -n xos-core

    This will show you the resources that have been created in the xos-core namespace.

    Cleanup

    When you're done and want to delete the deployed resources:

    pulumi destroy

    This will remove all resources created by the Pulumi program from your Kubernetes cluster. Confirm the action when prompted.

    Final Notes

    What we just walked through is a basic example of deploying a Helm chart on Kubernetes using Pulumi. Depending on the specifics of the xos-core chart, you may need to provide additional configuration through the values property.

    Remember to always check the Helm chart documentation for any prerequisites or setup that needs to be done before deployment and adjust your Pulumi code accordingly.
