1. Deploy the custom-iptables helm chart on Opensshift


    To deploy a Helm chart on an OpenShift cluster using Pulumi, you can use the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts to a Kubernetes cluster, and since OpenShift is a Kubernetes distribution, it applies there as well.

    First, you’ll need a Helm chart for custom-iptables. You can create one yourself, or you might find one that already exists. For deploying this chart onto OpenShift, you should ensure that your Pulumi stack is appropriately configured to communicate with the OpenShift cluster by setting up the kubeconfig correctly.

    Below is a Pulumi program in TypeScript that demonstrates how to deploy a Helm chart to an OpenShift cluster. Make sure you have the Helm chart for custom-iptables available, either in a local directory or hosted in a Helm repository.

    Here's what you need to do step by step in a Pulumi program:

    1. Import the necessary Pulumi libraries.
    2. Create a new Helm chart resource and specify the chart details such as name, version, and any custom values you may require.

    Here's the TypeScript program that does this:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Assuming that you have configured the kubeconfig for OpenShift in the environment // or using Pulumi configuration to supply the kubeconfig for connecting to the cluster. const customIptablesChart = new k8s.helm.v3.Chart("custom-iptables", { // Replace below with the appropriate chart values for your scenario. chart: "custom-iptables", // Specify the namespace if needed, otherwise, it will use the 'default' namespace. namespace: "your-namespace", // If the Helm chart is in a helm repository, you need to specify repository and version. // repository: "http://your-helm-chart-repository.com/", // version: "1.2.3", // You can also specify a path if the chart is located in the filesystem. // path: "./path-to-your-helm-chart", // Pass in values for the chart using the `values` property. values: { // These values would be specific to the custom-iptables chart. This is just an example. replicaCount: 1, // Add any other necessary values here. }, // If the Helm chart depends on CRDs or custom resources not included in the chart, use 'skipAwait: true' to tell Pulumi not to wait for the resources to become ready. // skipAwait: true, }, { provider: k8sProvider }); // If you're using a non-default provider, specify it here. // Export the resources created by the chart, if required. export const chartResources = customIptablesChart.resources;

    In the above program, you need to replace "your-namespace" with the namespace where you want to deploy the custom-iptables Helm chart. If your Helm chart resides in an external repository, you must specify the repository and version. If the chart is on your filesystem, use the path option instead.

    This Pulumi program will take care of deploying your custom-iptables Helm chart to the targeted OpenShift cluster when you run it using the Pulumi CLI. Remember to initialize a new Pulumi project using pulumi new if you haven't already set one up for this deployment.
