1. Deploy the logrotate helm chart on Opensshift


    To deploy the logrotate Helm chart on an OpenShift cluster, you'll need to use the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider. This provider allows you to declare Kubernetes resources using Pulumi's infrastructure-as-code approach. I'll guide you through setting this up in TypeScript.

    Before we start writing the code, make sure you have the following prerequisites:

    1. Pulumi CLI installed
    2. kubectl configured to connect to your OpenShift cluster
    3. Helm chart details for logrotate, including its repository URL and any necessary Helm values you wish to customize.

    Now, let's write the program. You will need to install the necessary Pulumi package for Kubernetes if you haven't already. You can do so by running npm install @pulumi/kubernetes.

    Here is the TypeScript program that accomplishes the deployment:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes provider instance that uses the current context from your kubeconfig file const provider = new k8s.Provider("openshift", { kubeconfig: k8s.config.tryFindKubeconfig() }); // Define the repository where the logrotate Helm chart is located const logrotateChartRepo = "https://charts.bitnami.com/bitnami"; // Specify the name of the Helm chart and the version const logrotateChartName = "logrotate"; const logrotateChartVersion = "x.y.z"; // Replace with the specific version you want to install // Define the settings for the logrotate Helm chart installation // Customize the 'values' object as needed based on your helm chart's configurable options const logrotateHelmChart = new k8s.helm.v3.Chart("logrotate", { chart: logrotateChartName, version: logrotateChartVersion, fetchOpts: { repo: logrotateChartRepo }, // Replace the following with your custom configuration values values: { // Example values, these will depend on your logrotate Helm chart's values image: { repository: "bitnami/logrotate", tag: "latest", }, schedule: "* * * * *", }, }, { provider }); // Export the name of the chart deployment export const chartName = logrotateHelmChart.metadata.apply(m => m.name);


    • We import the Kubernetes package from Pulumi which allows us to interact with Kubernetes resources.
    • We initialize a Pulumi Kubernetes Provider to interact with our OpenShift cluster. The provider uses your current Kubernetes context by default.
    • We define a constant that holds the repository URL of the logrotate Helm chart.
    • We specify the Helm chart name and version. The version must be defined as per the chart's available version in the repository.
    • We create a new Chart resource through Pulumi, which represents the logrotate Helm chart.
    • In the Chart resource, we define the chart parameter with the name of the chart, version, and fetchOpts that includes the repository URL.
    • We use the values property to configure any custom settings required by the Helm chart.
    • Finally, we export the name of the chart deployment as a stack output which can be useful for querying the deployment status with kubectl or Pulumi.

    When you run this Pulumi program with pulumi up, it will deploy the logrotate Helm chart into your OpenShift cluster.

    Please replace "x.y.z" with the actual version of the logrotate Helm chart you intend to deploy, and adjust the values as necessary according to your configuration needs.
