1. Deploy the prow helm chart on Kubernetes


    To deploy the Prow Helm chart on Kubernetes using Pulumi, you will need to use the Chart resource from the Pulumi Kubernetes provider. This will allow you to specify the Helm chart for Prow, and Pulumi will handle the deployment details.

    Below is a detailed Pulumi program, written in TypeScript, that you can use to deploy the Prow Helm chart onto a Kubernetes cluster. This program assumes you have already provisioned a Kubernetes cluster and have configured your Pulumi environment to communicate with it. Also, ensure you have the Helm chart details, such as the chart name and repository URL.

    The program performs the following actions:

    1. Importing Required Components: Import the necessary Pulumi classes and methods needed to deploy the Helm chart.
    2. Deploying a Helm Chart: Create a new Helm chart resource specifying the chart details for Prow.
    3. Exporting Outputs (Optional): Export any outputs you want to easily retrieve, such as service endpoints.

    Here's the Pulumi code for deploying the Prow Helm chart:

    import * as k8s from '@pulumi/kubernetes'; // This example deploys the Prow Helm chart into a Kubernetes cluster. // Replace the `chartRepoUrl` with the correct repository URL for Prow, // and provide a `chartVersion` corresponding to the version of Prow you want to deploy. // The `values` object contains configuration values for the Prow chart; adjust them as needed. const chartRepoUrl = 'YOUR_CHART_REPO_URL'; // TODO: Replace with the actual Helm chart repository URL const chartVersion = 'YOUR_DESIRED_CHART_VERSION'; // TODO: Specify the chart version const prowReleaseName = 'prow'; // You can name your release const namespace = 'prow'; // Specify the namespace Prow should be installed into // Initialize a Helm chart resource using the Prow Helm chart from its repository const prowChart = new k8s.helm.v3.Chart(prowReleaseName, { repo: 'prow', // This should correspond to the repo name in the Helm repository chart: 'prow', // This is the name of the chart in the repository namespace: namespace, version: chartVersion, fetchOpts: { repo: chartRepoUrl, }, values: { // Note: You'll need to fill out the Prow specific values required to deploy Prow successfully. // Check the Prow chart's values.yaml file or the chart repository's documentation for these. }, }, { provider: k8sProvider }); // Export any of the information from the chart that you might want access to // For example, export the webhook service IP or hostname for external access export const prowWebhookServiceHostname = prowChart.getResourceProperty( 'v1/Service', 'prow-hook', // The name of the webhook service deployed by Prow 'status' ).apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);

    Here's what each part of the code does:

    • import * as k8s from '@pulumi/kubernetes';: This line imports the Kubernetes package from Pulumi.
    • const chartRepoUrl...: These constants are placeholders that you need to replace with the details of the Prow Helm chart and your desired deployment.
    • new k8s.helm.v3.Chart(...): This creates a new Helm chart resource. You will need to pass the repository URL, chart name, version, and any custom values that the Prow chart requires.
    • export const prowWebhookServiceHostname: This line exports the hostname or IP of the webhook service set up by Prow, which you can use to interact with your Prow deployment.

    Please replace the placeholders (YOUR_CHART_REPO_URL, YOUR_DESIRED_CHART_VERSION) with actual values. Also, ensure you check the configuration options available for the Prow chart and populate the values field accordingly. You can usually find this information in the Prow Helm chart's documentation or values.yaml file.
