1. Deploy the base-openstack helm chart on Linode Kubernetes Engine


    To deploy the base-openstack Helm chart on the Linode Kubernetes Engine using Pulumi, you would follow the steps outlined below:

    1. Set up a Linode Kubernetes Cluster: The Linode Kubernetes Engine (LKE) allows you to deploy and manage container workloads. You will need to have a Linode cluster ready for deploying your Helm charts. You can either use an existing cluster or create a new one.

    2. Install Pulumi: If you don't already have Pulumi installed, you need to install it. This can be done by following the installation instructions on the Pulumi website.

    3. Configure Pulumi for Linode: Ensure you have the necessary credentials configured for Pulumi to interact with your Linode account and Kubernetes cluster.

    4. Write the Pulumi Code: With Pulumi, you use familiar languages such as TypeScript to declare your cloud resources. To deploy a Helm chart, you would use Pulumi's Kubernetes provider, which allows you to manage Kubernetes resources with declarative code.

    5. Deploy the Helm Chart: Use the Pulumi Kubernetes provider to install your chosen Helm chart to the LKE cluster.

    Below is a Pulumi TypeScript program that explains how you might deploy the base-openstack Helm chart to a Kubernetes cluster on Linode.

    import * as k8s from "@pulumi/kubernetes"; // Step 1: Configure your kubeconfig. Ensure your Pulumi program has access // to the kubeconfig file for the Linode Kubernetes Engine (LKE). const kubeconfig: string = "your-kubeconfig-data"; // Replace with the actual kubeconfig data or file path // Step 2: Helm Chart deployment. // You instantiate a Helm chart using the `k8s.helm.v3.Chart` class from the Pulumi Kubernetes provider. // You will need to provide the repo and chart names, along with any specific configurations // you want to override in the `values` object. const baseOpenstackHelmChart = new k8s.helm.v3.Chart("base-openstack-chart", { chart: "base-openstack", // The name of the chart // Replace with repository URL where the chart can be fetched from if needed. fetchOpts: { repo: "https://charts.example.com/" }, // You can provide custom values to your Helm chart. These values will override the defaults. // This is an empty example and should be filled with actual values as needed. values: { serviceName: "openstack-service", image: "openstack-image", // Add more Helm chart values here }, }, { provider: new k8s.Provider("lke-k8s", { kubeconfig }) }); // Step 3: Export resources created by the Helm chart // After the deployment, you can export certain values or URLs that may be needed to interact // with the resources that the Helm chart has deployed. This will depend on what resources // the `base-openstack` Helm chart creates. Below are placeholder exports for illustration. export const serviceUrl = baseOpenstackHelmChart.getResourceProperty( "v1/Service", "openstack-service", "status", "loadBalancer", "ingress", "0", "ip" );


    This Pulumi code snippet assumes that you have a Kubernetes cluster in Linode and you have the kubeconfig data ready to use. The program defines a Helm chart deployment using Pulumi’s Kubernetes (k8s) package.

    • The kubeconfig variable is where you would place your cluster's kubeconfig data or reference to your kubeconfig file. It's critical for Pulumi to access and manage your cluster.

    • k8s.helm.v3.Chart creates a Helm chart resource. You specify the chart name, repo, and values you want to override here. The repo URL is a placeholder and should be replaced with the actual repository where the base-openstack chart is stored.

    • The provider argument is used to explicitly pass a Pulumi Kubernetes provider configured with the LKE kubeconfig.

    • Finally, the export statement is used to output the IP address of a service, for example, that is created as a result of deploying the Helm chart. This can be used to access the deployed application from the internet.

    You would need to run pulumi up in a directory with this code to create the resources on Linode Kubernetes Engine. It will show you a preview of the resources that Pulumi will create, update, or delete. After reviewing the changes, you can confirm the deployment, and Pulumi will execute the actions to deploy the base-openstack Helm chart.
