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


    To deploy the ChatGPT Helm chart on Google Kubernetes Engine (GKE), you need to complete a few steps:

    1. Create a GKE cluster,
    2. Configure kubectl to connect to the cluster,
    3. Install Helm on your local machine (or wherever you want to run the Helm commands from),
    4. Use Helm to deploy the ChatGPT Helm chart.

    Below is a Pulumi program written in TypeScript that automates the first step, which is creating a GKE cluster. Note that you'll need to perform the additional steps manually after the cluster is set up.

    First, make sure you have the Pulumi CLI and Google Cloud SDK installed, and that you’re authenticated with Google Cloud.

    Now, let’s walk through the code. The program uses the @pulumi/gcp package to create a new GKE cluster. Here's a detailed explanation of what each section of the program does:

    • It starts by importing the required Pulumi and GCP packages.
    • Then, a new Kubernetes cluster is defined using gcp.container.Cluster.
    • The cluster is configured with basic settings appropriate for most use cases. You can adjust the settings to match your specific needs.
    • The program exports the cluster's name and kubeconfig, which are outputs you will use to connect to the cluster with kubectl.
    import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Create a GCP GKE cluster. const cluster = new gcp.container.Cluster("chatgpt-cluster", { initialNodeCount: 2, minMasterVersion: "latest", nodeVersion: "latest", nodeConfig: { machineType: "n1-standard-1", oauthScopes: [ "https://www.googleapis.com/auth/cloud-platform", ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Manufacture a GKE-style kubeconfig. Note that this is slightly "different" // because of the way GKE requires gcloud to be in the picture for cluster // authentication (rather than using the client cert/key directly). 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 `; });

    After executing this program with the Pulumi CLI, you'll have a new GKE cluster ready to go. Next, you would install Helm and use it to deploy the ChatGPT Helm chart to the cluster. Here's a brief overview of those steps:

    1. Install Helm: Follow the instructions for your operating system to install Helm from Helm's documentation.

    2. Initialize Helm and Tiller (for Helm v2 only): With Helm v3, Tiller is no longer required. If using Helm v2, you would need to run helm init to install Tiller on your cluster. Note that its use is deprecated.

    3. Add the Helm repository: If the ChatGPT Helm chart is hosted in a Helm repository, you would use helm repo add to add that repository.

    4. Install the Helm Chart: Use helm install to deploy the chart to your GKE cluster. You'll need the name of the Helm chart and the repository where it's hosted.

    5. Access the ChatGPT application: After you've deployed the Helm chart, follow the post-installation instructions to access the ChatGPT application. This usually involves setting up port forwarding or an ingress controller depending on how the Helm chart is configured to expose services.

    By following the above detailed Pulumi program and subsequent Helm installation steps, you will have ChatGPT running on a GKE cluster.
