1. Deploy the senlin helm chart on Opensshift


    To deploy a Helm chart on an OpenShift cluster using Pulumi, you would need to set up a Pulumi project using the Kubernetes package. This package allows you to interact with your Kubernetes cluster and deploy the Helm charts using Pulumi's infrastructure as code approach.

    To achieve this, you will need access to your OpenShift cluster and have the kubectl command-line tool configured to communicate with your cluster. Ensure you also have the Helm CLI installed if you need to customize the Helm chart or fetch values from the Helm repository.

    Below you'll find a Pulumi program written in TypeScript that demonstrates how to deploy a Helm chart to an OpenShift cluster. The example assumes you are deploying the senlin Helm chart, which you will need to locate in a Helm repository or have it available locally.

    This program performs the following actions:

    • Imports the required Pulumi Kubernetes package.
    • Creates a new Helm chart resource, pointing to the location of the senlin Helm chart.
    • Specifies any necessary configuration values that the chart may require.
    import * as k8s from "@pulumi/kubernetes"; // Replace the following variables with the appropriate values for your setup. const helmRepoUrl = "https://charts.example.com/"; // The URL for the Helm repository that contains the senlin chart. const chartName = "senlin"; // The name of the chart in the repository. const chartVersion = "1.2.3"; // The version of the chart you wish to deploy. const releaseName = "senlin-release"; // A unique name for the Helm release. const namespace = "default"; // The namespace where you want to deploy the chart. const senlinChart = new k8s.helm.v3.Chart(releaseName, { // The repository where the Helm chart is located. repo: helmRepoUrl, // The name of the chart in the repository. chart: chartName, // Optionally specify the version of the chart. version: chartVersion, // Specify the namespace for deploying the Helm chart. namespace: namespace, // Optional: Specify values for the Helm chart's configuration. // This should reflect the values needed for the senlin Helm chart to configure its deployment correctly. values: { // Example value structure. Please change according to your chart's requirements. // replicaCount: 3, // image: { // repository: "senlin/repo", // tag: "latest", // }, // ... }, // Optional: Specify transformations for customizing the behavior of the created resources. // Useful if you need to modify the resources defined in the Helm chart before they get deployed. transformations: [ // Example transformation to add an annotation to every resource. // (resource) => { // if (resource.metadata) { // resource.metadata.annotations = { "custom-annotation": "custom-value" }; // } // }, ], }, { provider: /* the provider configuration if other than default */ }); // Export the generated YAML for this chart, if desired. export const chartYaml = senlinChart.resources;

    To execute this Pulumi program, you will need to perform the following steps:

    1. Make sure you have installed Pulumi CLI and Node.js.
    2. Set up a new Pulumi project with pulumi new.
    3. Replace the placeholder pulumi-ts-program with the actual name of the TypeScript file.
    4. Fill in the const variables with the appropriate values for the senlin chart.
    5. Run pulumi up to deploy this Helm chart to your OpenShift cluster.

    Please ensure that your OpenShift cluster is configured correctly with kubectl and the helm command is available to inspect or manage Helm charts.

    This program can be extended with more configurations and Pulumi resources, depending on the complexity and requirements of your deployment. Additionally, you can include Pulumi stack exports to retrieve important information from the deployment, such as service URLs or ingress points, and monitor the status of the deployed resources.
