1. Deploy the openshift-logforwarding-splunk helm chart on Google Kubernetes Engine (GKE)


    To deploy the openshift-logforwarding-splunk Helm chart on a Google Kubernetes Engine (GKE) cluster, you need to perform several steps:

    1. Create a GKE cluster.
    2. Configure kubectl to connect to the GKE cluster.
    3. Use Helm to deploy the openshift-logforwarding-splunk chart.

    We will use Pulumi to programmatically accomplish these steps. Pulumi allows us to define our infrastructure as code using programming languages such as TypeScript.

    Below, I will provide a Pulumi program written in TypeScript. This program will define the necessary infrastructure using GKE to host the Helm chart, and then proceed to deploy the chart.

    First, let's go through the code step by step:

    • Define a GKE cluster using the Cluster resource from the @pulumi/google-native/container/v1beta1 package. This package provides us with the native Google Cloud resources.
    • Set up Kubeconfig so that we can interact with the GKE cluster using kubectl.
    • Deploy the Helm chart using the Release resource from the @pulumi/kubernetes/helm.sh/v3 package. This resource represents a Helm chart release.

    Now let's look at the code:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a GKE cluster const cluster = new gcp.container.Cluster("gke-cluster", { initialNodeCount: 2, nodeVersion: "latest", minMasterVersion: "latest", location: "us-central1", }); // Export the Cluster name export const clusterName = cluster.name; // Retrieve the Kubeconfig for the GKE cluster const kubeconfig = pulumi. all([cluster.name, cluster.endpoint, cluster.masterAuth]). apply(([name, endpoint, masterAuth]) => { const context = `${gcp.config.project}_${gcp.config.zone}_${name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${masterAuth.clusterCaCertificate} server: https://${endpoint} name: ${context} contexts: - context: cluster: ${context} user: ${context} name: ${context} current-context: ${context} kind: Config preferences: {} users: - name: ${context} user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Use Pulumi's Kubernetes provider to interact with the GKE cluster using the provided kubeconfig const provider = new k8s.Provider("gke-k8s", { kubeconfig: kubeconfig, }); // Deploy the openshift-logforwarding-splunk Helm chart using Pulumi's Helm Release resource const logForwardingChart = new k8s.helm.v3.Chart("openshift-logforwarding-splunk", { chart: "openshift-logforwarding-splunk", version: "X.Y.Z", // Specify the chart version you want to deploy fetchOpts: { repo: "https://helm-repo-url/", // Specify the Helm repository URL where the chart can be found }, // You might need to add additional configuration settings for the chart, // such as values or namespace depending on the chart requirements. values: { // Add required Helm chart values here }, }, { provider }); // Export the chart status export const chartStatus = logForwardingChart.status;

    Make sure to replace X.Y.Z with the chart version and https://helm-repo-url/ with the actual Helm repository URL containing the openshift-logforwarding-splunk chart.

    This program starts by declaring a new GKE cluster with two nodes. Once the cluster is available, it extracts the kubeconfig, which is used to set up a Kubernetes provider. Finally, it defines a Helm chart release for openshift-logforwarding-splunk.

    Important: Before running this program, ensure you've properly configured Pulumi with your GCP credentials, and that you've installed the Pulumi CLI on your machine.

    To run this Pulumi program, create a new directory, change into it, and run pulumi new typescript to create a new TypeScript Pulumi project. Replace the contents of index.ts with the code provided above. Afterward, you can run pulumi up to deploy the infrastructure.

    Please ensure that you look up the Helm chart's specific values and version to customize your deployment according to openshift-logforwarding-splunk Helm chart requirements.
