1. Deploy the ibm-cp4s-threatmgmt-instance helm chart on Google Kubernetes Engine (GKE)


    To deploy an IBM Cloud Pak for Security (cp4s) Threat Management instance using a Helm chart on Google Kubernetes Engine (GKE), we first need to set up the GKE cluster. Once the cluster is up and running, we will use the Pulumi harness package to deploy our Helm Chart to the GKE cluster.

    Here's a detailed explanation of the steps we'll be taking in the Pulumi program:

    1. Create a GKE cluster using the @pulumi/google-native package, which provides native Google Cloud resources.
    2. Once the cluster is created, we configure Pulumi to use the generated Kubernetes credentials, so that we can operate the GKE cluster using Pulumi's Kubernetes provider.
    3. Deploy the IBM Helm chart to the GKE cluster. We'll interact with Helm using the @pulumi/harness package, which provides a resource type for deploying Helm charts.

    Now let's proceed with the Pulumi TypeScript program to achieve this:

    import * as gcp from '@pulumi/gcp'; import * as k8s from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; import * as harness from '@pulumi/harness'; // Step 1: Create a GKE cluster const cluster = new gcp.container.Cluster("cp4s-cluster", { // Define the properties for the GKE cluster, such as location, node count, and machine types. initialNodeCount: 1, minMasterVersion: "latest", nodeVersion: "latest", location: "us-central1", nodeConfig: { machineType: "n1-standard-4", // example machine type oauthScopes: [ "https://www.googleapis.com/auth/cloud-platform", ], }, }); // Step 2: Obtain the Kubeconfig for the created 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 `; }); // Step 3: Setup the Kubernetes provider using obtained Kubeconfig from the GKE cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Step 4: Deploy the IBM Cloud Pak for Security Threat Management instance using a Helm chart const cp4sChart = new harness.service.Helm("cp4s-threatmgmt-instance", { // Specifications to identify and deploy the Helm chart from the correct repository. chart: "ibm-cp4s-threatmgmt-instance", // Define Helm chart version and other parameters to configure the deployment to your needs. version: "1.0.0", namespace: "ibm-cp4s", values: { // You need to provide values that are necessary for the Helm chart. // Replace these with actual values needed by the ibm-cp4s chart. customValue1: "value1", customValue2: "value2", }, }, { provider: k8sProvider }); // Ensure the Helm chart is deployed using the Kubernetes provider we created. // Export the Kubeconfig and other important data to access the cluster and deployed Helm chart. export const kubeconfigOutput = kubeconfig;

    This program will perform the following actions:

    • Create a GKE cluster with the desired configuration.
    • Obtain the Kubeconfig file needed to interact with the cluster.
    • Setup a Pulumi Kubernetes provider using the obtained Kubeconfig.
    • Deploy the IBM Cloud Pak for Security Threat Management instance using a Helm chart and the Helm resource from the Harness package.

    Please make sure to replace the placeholders in the values object with the actual configuration values required by the ibm-cp4s-threatmgmt-instance Helm chart. Additionally, Helm chart values and version may differ based on the available versions in the Helm chart repository you intend to use, so ensure that you have the correct details from the Helm chart's documentation.

    Also remember to install all necessary Pulumi packages using npm or yarn before running the program:

    npm install @pulumi/gcp @pulumi/kubernetes @pulumi/pulumi @pulumi/harness

    Exported output, such as the Kubeconfig in this case, allows you to connect to the Kubernetes cluster using kubectl or other Kubernetes management tools. You can obtain this output after running pulumi up by using the pulumi stack output command.

    I hope this helps you get started with deploying IBM Cloud Pak for Security on GKE using Pulumi! If you need more details about the specific Helm chart configuration, please refer to the official documentation of the IBM Cloud Pak for Security.
