Deploy the ozwdaemon helm chart on Google Kubernetes Engine (GKE)
TypeScriptTo deploy the
ozwdaemon
Helm chart on Google Kubernetes Engine (GKE), you will need to perform a series of steps. First, you'll create a GKE cluster, then you'll install Helm and use it to deploy theozwdaemon
chart to your cluster. I will guide you through the process using Pulumi with TypeScript.Here's a step-by-step walkthrough of what you need to do:
-
Setting up GKE Cluster: We use the
gcp.container.Cluster
resource from Pulumi's GCP package to set up a new Kubernetes cluster on GKE. We define the necessary properties such as the desired location for the cluster and node count. -
Configuring K8s Provider: Once the cluster is up and running, we need to configure the Pulumi Kubernetes provider to target our newly created GKE cluster. We fetch the cluster’s kubeconfig for this purpose.
-
Installing Helm and Deploying the Chart: Helm is a package manager for Kubernetes, which allows us to deploy an application packaged as a Helm chart. We use Pulumi's
kubernetes.helm.v3.Chart
resource to deploy theozwdaemon
chart onto our GKE cluster.
Let's start by installing the necessary Pulumi packages using npm:
npm install @pulumi/gcp @pulumi/kubernetes
Now, you can use the following Pulumi program to create your GKE cluster and deploy the
ozwdaemon
Helm chart:import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as kubernetes from "@pulumi/kubernetes"; // Create a GKE cluster. const cluster = new gcp.container.Cluster("ozwdaemon-cluster", { initialNodeCount: 2, nodeVersion: "latest", minMasterVersion: "latest", location: "us-central1-a", 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 Kubernetes cluster name. export const clusterName = cluster.name; // Export the Kubeconfig so that the Kubernetes provider can use it. 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: ${context} user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Create a Kubernetes Provider that uses our kubeconfig. const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the ozwdaemon Helm chart const ozwdaemonChart = new kubernetes.helm.v3.Chart("ozwdaemon", { chart: "ozwdaemon", fetchOpts:{ repo: "https://openzwave.github.io/openzwave-helm/", }, // Specify the values for the Helm chart here; you can customize the Helm chart settings as needed. values: { // Add your desired chart values here }, }, { provider: k8sProvider }); // Export the chart's public service endpoint. export const ozwdaemonEndpoint = pulumi.interpolate`https://${ozwdaemonChart.getResourceProperty("v1/Service", "ozwdaemon", "status").loadBalancer.ingress[0].ip}`;
In the above code:
- The
gcp.container.Cluster
creates a new GKE cluster. You may want to change the number of nodes, machine type, and location to fit your need. - The
kubeconfig
is generated from the cluster information. This kubeconfig is required to authenticate kubectl and the Pulumi Kubernetes provider to your GKE cluster. - The
kubernetes.Provider
is set up with the aforementioned kubeconfig, allowing Pulumi to manage resources in your GKE cluster. - The
kubernetes.helm.v3.Chart
resource is used to deploy theozwdaemon
chart from its Helm repository. You should specify thevalues
field according to your needs to configure the OzW Daemon. - Finally, an endpoint is exported, which allows you to access the
ozwdaemon
service outside your cluster, if the chart exposes one.
To deploy this Pulumi program:
- Ensure you’ve set up Pulumi and authenticated with Google Cloud.
- Run
pulumi up
to create the GKE cluster and deploy the Helm chart.
Please replace the placeholders and chart values with the configuration appropriate for your use case. Note that deploying and managing Kubernetes clusters incurs costs in the cloud provider.
