1. Deploy the xos-core helm chart on Linode Kubernetes Engine

    TypeScript

    To deploy the xos-core Helm chart on Linode Kubernetes Engine, you will need to follow these steps, which involve setting up a Kubernetes cluster on Linode, and then using the Pulumi Kubernetes provider to deploy a Helm chart onto the cluster.

    Here is a detailed guide on how you can accomplish this using Pulumi with TypeScript:

    Step 1: Installing Pulumi

    Before you begin, ensure you have Pulumi installed. If not, you can install it by following the instructions on the Pulumi website.

    Step 2: Setting up the Linode Kubernetes Engine Cluster

    You would typically use Pulumi's Linode provider to provision a Kubernetes cluster on Linode. As of my knowledge cutoff date in early 2023, there is no dedicated Pulumi provider for Linode; instead, you can manually create a Kubernetes cluster in the Linode Cloud Manager and obtain the kubeconfig file.

    Step 3: Configuring Pulumi to Use Your Linode Cluster

    With your Linode Kubernetes Engine cluster created and your kubeconfig file in hand, you will need to set the Pulumi Kubernetes provider to point to your Linode cluster. This is typically done by setting the kubeconfig directly or referencing the kubeconfig file.

    Step 4: Writing the Pulumi Program to Deploy xos-core

    The Pulumi program will use the kubernetes package to deploy the xos-core Helm chart. You will need to specify the chart's repository and name in a Chart resource.

    Here's the TypeScript code that accomplishes this:

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

// A Pulumi program that deploys the `xos-core` Helm chart on a Linode Kubernetes cluster.

// Create a provider that points to your Linode Kubernetes cluster.
const linodeProvider = new kubernetes.Provider("linodeK8s", {
    kubeconfig: "<your kubeconfig here>",
});

// Deploy the `xos-core` helm chart using the Helm Chart resource.
const xosCoreChart = new kubernetes.helm.v3.Chart("xos-core", {
    chart: "xos-core",
    version: "<chart version>", // Specify the version of the chart you wish to deploy
    fetchOpts:{
        repo: "http://<helm chart repository>", // Provide the Helm chart repository URL here
    },
}, { provider: linodeProvider });

// Export the public IP to access xos-core, if applicable.
export const xosCoreIp = xosCoreChart.getResourceProperty(
    "v1/Service", "<xos-core-service-name>", "status"
).apply(status => status.loadBalancer.ingress[0].ip);

    Replace <your kubeconfig here> with the actual kubeconfig data or a file path to the kubeconfig for your Linode Kubernetes Engine cluster. The chart property should be set to the name of the Helm chart you want to deploy (xos-core), and the repository URL where the chart is located should be specified in the fetchOpts.repo property.

    Finally, if you need to expose xos-core through a public IP, Pulumi supports exporting such details by extracting properties from deployed resources.

    Note:

    • Remember to replace placeholder strings with actual values.
    • Make sure you have the required permissions set up in your Linode account to manage resources via Pulumi.

    When you run this Pulumi program, it will:

    • Configure the Kubernetes provider to connect to your Linode Kubernetes cluster using the provider kubeconfig.
    • Use the Helm Chart resource to deploy the xos-core Helm chart onto your cluster.

    Running the Program

    To run this program, you would execute the following Pulumi CLI commands in your terminal:

    pulumi up

    This command will preview the deployment and, upon confirmation, it will provision the defined resources in your Linode Kubernetes Engine cluster.

    Conclusion

    By following these steps, your xos-core application will be deployed on your Linode Kubernetes Cluster. You can then interact with the application using the IP or domain you have set up to access your services.
