1. Deploy the podsecuritypolicy helm chart on Google Kubernetes Engine (GKE)


    To deploy the podsecuritypolicy Helm chart on Google Kubernetes Engine (GKE), you will first need to set up a GKE cluster, then use Pulumi's Helm resource to deploy the chart to that cluster. Below is a step-by-step guide to achieve this using Pulumi with TypeScript.

    Step 1: Set Up GKE Cluster

    First, you create a GKE cluster that the Helm chart will be deployed to. For this, you'll use the google-native.container.v1.Cluster resource.

    Step 2: Deploy the Helm Chart

    After the cluster is ready, you deploy the podsecuritypolicy Helm chart to your GKE cluster using the @pulumi/kubernetes library, which provides a helm.v3.Chart resource for this purpose.

    Here is a TypeScript program that does these things:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create the GKE cluster const cluster = new gcp.container.Cluster("gke-cluster", { initialNodeCount: 1, nodeVersion: "latest", minMasterVersion: "latest", }); // Export the Cluster name export const clusterName = cluster.name; // Configure K8s provider to use the GKE cluster credentials const k8sProvider = new k8s.Provider("gke-k8s", { kubeconfig: cluster.endpoint.apply(endpoint => { // Use the cluster name and location to get the Kubeconfig for the GKE cluster return gcp.container.getCluster({ name: cluster.name, location: cluster.location, }).then(clusterInfo => { const context = `${gcp.config.project}_${gcp.config.zone}_${cluster.name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${clusterInfo.masterAuth[0].clusterCaCertificate} server: https://${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 2: Deploy the podsecuritypolicy Helm chart const podSecurityPolicyChart = new k8s.helm.v3.Chart("podsecuritypolicy-chart", { chart: "podsecuritypolicy", version: "1.0.0", // specify the exact chart version you want to deploy fetchOpts: { repo: "https://charts.your-repo.com", // replace with the URL of your chart repository }, }, { provider: k8sProvider }); // Export the status of the deployed Helm chart export const helmChartStatus = podSecurityPolicyChart.status;


    • We import the required Pulumi packages for GCP and Kubernetes.
    • We declare a GKE cluster with gcp.container.Cluster and specify some mandatory options such as the initial node count and versioning details.
    • We create a kubeconfig that enables the Pulumi Kubernetes provider to communicate with your GKE cluster.
    • Using the Kubernetes provider, we deploy a Helm chart named podsecuritypolicy. We specify the chart's name and version, you will need to specify the chart repository where podsecuritypolicy is hosted (the repo option).
    • We export the name and status of the cluster as well as the status of the deployed Helm chart. These will be printed to the console when you run pulumi up.

    Before running this code with Pulumi, ensure that you have access to the GKE and the Helm chart you wish to deploy is accessible in the specified Helm repository.

    Replace "https://charts.your-repo.com" with the actual URL where your chosen Helm chart is hosted.

    Also, it's worth noting that at the time of writing this, Google has deprecated PodSecurityPolicies as of version 1.21 and is removing it in version 1.25. It is encouraged to use other security mechanisms provided by Kubernetes such as OPA Gatekeeper or Kyverno. Make sure to adjust your security policies based on the best practices and current tools recommended by the Kubernetes community.

    To run this Pulumi program, you would execute pulumi up within the directory where this code resides, and Pulumi will handle the provisioning and updating of the resources.
