1. Deploy the onos helm chart on Kubernetes

    TypeScript

    To deploy the ONOS (Open Network Operating System) Helm chart on a Kubernetes cluster using Pulumi, you can leverage the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts in a Kubernetes cluster easily through Pulumi's infrastructure as code approach.

    Below is a TypeScript program that demonstrates how to achieve this. We'll start by installing the necessary Pulumi package, setting up a Kubernetes provider (assuming you have already configured kubectl with the cluster where you want to deploy the ONOS chart), and then we'll proceed to deploy the Helm chart.

    Here is the step-by-step program to deploy the ONOS Helm chart using Pulumi:

    import * as k8s from "@pulumi/kubernetes"; // Define ONOS Helm chart settings const onosChartName = "onos"; const onosReleaseName = "my-onos-release"; // You can choose any release name you prefer const onosChartVersion = "x.y.z"; // Replace with the specific version you want to deploy const onosChartRepo = "https://charts.onosproject.org"; // Replace with the correct Helm repository URL for ONOS // Deploy ONOS using Helm chart const onosChart = new k8s.helm.v3.Chart(onosReleaseName, { chart: onosChartName, version: onosChartVersion, fetchOpts: { repo: onosChartRepo, } }); // Export the ONOS service endpoint export const onosServiceEndpoint = onosChart.getResource("v1/Service", "default", onosReleaseName) .status.loadBalancer.ingress[0].hostname;

    In the above code:

    • We import the @pulumi/kubernetes package to interact with a Kubernetes cluster.
    • We set up variables to specify the name, release name, version, and repository URL of the ONOS Helm chart.
    • We create an instance of the Chart resource from the @pulumi/kubernetes package. This will instruct Pulumi to deploy the specified version of the ONOS Helm chart to the Kubernetes cluster that kubectl is currently configured to use.
    • We also use the getResource method to obtain the ONOS service created by the Helm chart deployment and export its external endpoint as a stack output. This will allow you to access the ONOS service once it's deployed.

    Please replace "x.y.z" with the correct Helm chart version of ONOS that you wish to deploy, and ensure that the repository URL is also correct.

    To run this program, you'd use the following Pulumi CLI commands:

    1. Navigate to the directory containing the above TypeScript file.
    2. Run pulumi up to preview and deploy the changes.

    If you have not done so already, you will need to install Pulumi and configure it to work with your chosen cloud and Kubernetes environments. Detailed instructions on that setup process can be found in the Pulumi documentation.
