1. Deploy the remark42 helm chart on Google Kubernetes Engine (GKE)


    To deploy the remark42 Helm chart on Google Kubernetes Engine (GKE), you will first need to create a GKE cluster, and then use Pulumi's helm.v3.Chart resource to manage the deployment of the Helm chart.

    Here is a step-by-step guide on how you can accomplish this using Pulumi with TypeScript:

    1. Set Up Your GKE Cluster: You will use the google-native.container/v1beta1.Cluster resource to create a new Kubernetes cluster in GKE. This involves specifying the details of the cluster such as its name, the description, and node configuration.

    2. Deploy the Remark42 Helm Chart: Once you have a Kubernetes cluster up and running, you can deploy the remark42 Helm chart using Pulumi's kubernetes.helm.v3.Chart resource. This resource abstracts Helm's operations like helm install and helm update.

    Here is the TypeScript program that performs these steps:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Set Up Your GKE Cluster const cluster = new gcp.container.Cluster("remark42-gke-cluster", { initialNodeCount: 1, nodeVersion: "latest", minMasterVersion: "latest", nodeConfig: { machineType: "n1-standard-1", oauthScopes: [ "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring", ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Step 2: Configure K8s provider to deploy the Helm chart using the GKE cluster credentials const k8sProvider = new k8s.Provider("remark42-k8s", { kubeconfig: cluster.kubeConfigRaw, }); // Step 3: Deploy the remark42 Helm chart const remark42Chart = new k8s.helm.v3.Chart("remark42", { chart: "remark42", // Replace with the repository that hosts the remark42 chart if it's not in the default repo fetchOpts: { repo: "https://path-to-remark42-helm-repo/", }, }, { provider: k8sProvider }); // Export the Helm chart deployment status export const remark42DeploymentName = remark42Chart.status.apply(status => status.name);

    What this program does:

    1. Initialize a new GKE cluster with a single node pool. The initialNodeCount, nodeVersion, minMasterVersion, and nodeConfig parameters define the configuration of the cluster's nodes. The oauthScopes provide the nodes with the required permissions.

    2. Define a Kubernetes provider to interact with the created GKE cluster. The kubeconfig is retrieved from the GKE cluster, which is used by the provider to authenticate with the Kubernetes cluster.

    3. Deploy the remark42 Helm chart to your GKE cluster. You specify the Helm chart's name and the repository where it is located. The { provider: k8sProvider } option ensures that the Helm chart is deployed using the credentials from the GKE cluster created above.

    Exported Outputs:

    • clusterName: The name of the created GKE cluster which you can use to reference the cluster in the future.
    • remark42DeploymentName: The name of the running Helm chart deployment for remark42. This may be useful for checking the status and managing the deployment later on.


    • Make sure you have Pulumi installed and configured for use with GCP.
    • Ensure that you are authenticated with GCP and have the necessary permissions to create resources in GKE.

    After writing the code above, you can run it using Pulumi CLI commands:

    • pulumi up: Preview and deploy changes.
    • pulumi stack output: See the exported outputs.
    • pulumi destroy: Tear down all resources.

    Remember to replace the placeholder for the chart repository ('https://path-to-remark42-helm-repo/') with the actual URL to the remark42 Helm chart repository if it is hosted outside the default Helm chart repositories.

    This program provides a foundation to start with. You will need to adjust the nodeConfig and other parameters of the GKE cluster based on your application's specific needs and GCP quotas. Additionally, you might need to configure the remark42 Helm chart with the appropriate values based on your desired configuration for the application.
