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


    To deploy the "ohmyform" Helm chart on Google Kubernetes Engine (GKE), we'll go through several steps to set up the infrastructure. The process involves provisioning a GKE cluster, configuring Kubernetes for Helm (including setting up Tiller if using Helm v2), and then deploying the Helm chart onto the cluster.

    Here's a high-level overview of the steps:

    1. Create a GKE cluster.
    2. Configure the local kubectl to connect to the GKE cluster (this step is done outside of the Pulumi program).
    3. Install Helm to the Kubernetes cluster (if using Helm v2, this would include setting up Tiller with the correct permissions).
    4. Deploy the "ohmyform" Helm chart using Pulumi's Kubernetes provider.

    Below is a Pulumi TypeScript program that creates a GKE cluster and deploys the "ohmyform" Helm chart. This example assumes you are using Helm v3, which does not require Tiller. Make sure you have your Google Cloud credentials configured for Pulumi and gcloud CLI on your local machine.

    First, we import the necessary Pulumi package modules, then we specify the details of the GKE cluster such as the node count, machine type, and the node version.

    After the cluster is provisioned, we configure kubectl automatically with Pulumi's provider functionality to connect to the newly created GKE cluster.

    Finally, we deploy the "ohmyform" Helm chart to the GKE cluster using kubernetes.helm.v3.Chart resource.

    import * as pulumi from '@pulumi/pulumi'; import * as gcp from '@pulumi/gcp'; import * as k8s from '@pulumi/kubernetes'; const name = 'ohmyform'; // Create a GKE cluster const cluster = new gcp.container.Cluster(name, { initialNodeCount: 2, nodeVersion: "latest", minMasterVersion: "latest", nodeConfig: { preemptible: true, 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; // Export the Kubeconfig to be used by kubectl and other clients outside of Pulumi export 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 `; }); // Create a Kubernetes provider instance that uses our cluster from above. const clusterProvider = new k8s.Provider(name, { kubeconfig: kubeconfig, }); // Deploy the "ohmyform" Helm chart const ohmyformChart = new k8s.helm.v3.Chart(name, { repo: "ohmyform", chart: "ohmyform", version: "1.0.0", // specify the exact chart version }, { provider: clusterProvider }); // Export the Helm chart deployment name export const ohmyformChartName = ohmyformChart.name;

    To apply this Pulumi program:

    1. Run pulumi up to preview and deploy the changes. Pulumi will print out the proposed changes before making them.
    2. If the proposed changes are acceptable, select yes to deploy the resources.


    • Before running this Pulumi program, ensure that you are logged into the gcloud CLI and have selected the appropriate project with gcloud config set project <your-gcp-project>.
    • Although we set the kubeconfig output for convenience, in practice, Pulumi handles the kubeconfig internally when deploying resources to Kubernetes with the k8s.Provider.
    • Be aware of your Kubernetes and Google Cloud costs. The resources created by this program may incur charges.
    • Modify the Helm chart and cluster configurations according to your specific requirements and the specifications of the "ohmyform" Helm chart.
    • The chart version specified must be available in the "ohmyform" Helm repository. Adjust the version as necessary.
