1. Deploy the webrtc-observer helm chart on Google Kubernetes Engine (GKE)

    TypeScript

    To deploy the webrtc-observer Helm chart on Google Kubernetes Engine (GKE), you will need to follow these steps:

    1. Set up a GKE cluster: First, you need to set up your Kubernetes cluster within GKE. This will be the environment where your helm chart is deployed.

    2. Install and Configure Pulumi: Pulumi must be installed, and you should authenticate with your Google Cloud account, so Pulumi can manage resources on your behalf. You'll also need to install the Pulumi Kubernetes provider.

    3. Write the Pulumi program: Define your GKE cluster and the Helm chart deployment within a Pulumi program.

    4. Deploy via Pulumi: Run pulumi up to deploy your infrastructure - this includes both the GKE cluster and the webrtc-observer Helm chart.

    Let's write a Pulumi program to perform these actions. Below is a TypeScript program that defines a GKE cluster and deploys the webrtc-observer Helm chart on it.

    import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; const name = "webrtc-observer"; // Create a GKE cluster const cluster = new gcp.container.Cluster(name, { initialNodeCount: 2, nodeConfig: { preemptible: true, machineType: "n1-standard-1", }, }); // Export the Cluster name export const clusterName = cluster.name; // Export the Kubeconfig 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 with the kubeconfig. const k8sProvider = new k8s.Provider(name, { kubeconfig: kubeconfig, }); // Deploy the webrtc-observer Helm chart const webrtcObserverChart = new k8s.helm.v3.Chart(name, { chart: "webrtc-observer", version: "1.0.0", // specify the exact chart version fetchOpts: { repo: "http://<your-helm-chart-repository>", // replace with the Helm chart repo URL }, }, { provider: k8sProvider }); // Export the Helm chart status export const chartStatus = webrtcObserverChart.status;

    In the code above, pulumi imports are done for the Pulumi SDK, the GCP module, and the Kubernetes module. A GKE cluster is then defined with a given node count and machine type specification.

    After defining the GKE cluster, the program exports two important pieces of information: the cluster name and the kubeconfig. The kubeconfig is required for the Kubernetes provider to interact with your cluster.

    Then, a Provider resource is created, representing the Kubernetes provider instance; this allows Pulumi to deploy resources to this specific Kubernetes cluster.

    Finally, the webrtc-observer Helm chart is deployed using Pulumi's Helm support. You have to specify the exact version of the chart and its source repository. After the deployment, the status of the Helm chart is exported.

    To run the above program:

    1. Save the code to a file with a .ts extension, like index.ts.
    2. Ensure Pulumi CLI is installed and you have authenticated with GCP gcloud CLI.
    3. Run pulumi up in the directory where your index.ts is located.
    4. Pulumi will show you a preview of actions and require confirmation before proceeding to set up the infrastructure and deploy the Helm chart.

    Remember to replace the <your-helm-chart-repository> placeholder with the actual Helm repository URL where the webrtc-observer chart is hosted.

    This code should create your GKE cluster and then deploy the webrtc-observer Helm chart within it. Please ensure you have the correct permissions and that your Google Cloud and Pulumi configurations are set up before running the code.
