Deploy the bytesafe-ce helm chart on Google Kubernetes Engine (GKE)

Question

Pulumi · Accepted Answer

To deploy the `bytesafe-ce` Helm chart on Google Kubernetes Engine (GKE) using Pulumi, you'll need to perform several steps:

1. **Create a GKE Cluster**: Provision a Kubernetes cluster on GKE where you will deploy your Helm Chart.
2. **Install and Configure Helm**: Set up Helm, the package manager for Kubernetes, to deploy your chart.
3. **Deploy the Helm Chart**: Deploy the `bytesafe-ce` Helm chart to your cluster.

Below is an explanation of the Pulumi code that accomplishes these steps.

### 1. Create a GKE Cluster
First, we use the `gcp.container.Cluster` resource to create a new GKE cluster. Here you need to specify the name of the cluster, the location, and any configurations specific to the requirements of `bytesafe-ce`.

### 2. Install and Configure Helm
Once the cluster is available, we use the `kubernetes.helm.v3.Chart` resource from Pulumi’s Kubernetes provider to deploy the Helm chart. This resource is an abstraction to deploy charts similar to how you would use `helm install` or `helm upgrade` commands.

### 3. Deploy the Helm Chart
In the `kubernetes.helm.v3.Chart` resource, you specify the name of the chart (bytesafe-ce), and any values or configurations required for the chart.

Here’s a full Pulumi TypeScript program that shows these steps. You’ll need to have both Pulumi and the Google Cloud SDK set up and configured for this code to work:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";
import * as k8s from "@pulumi/kubernetes";

// Create a GKE cluster
const cluster = new gcp.container.Cluster("my-gke-cluster", {
    initialNodeCount: 2,
    nodeConfig: {
        // Recommended to choose a machine type based on the workload needs of bytesafe-ce
        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 and Kubeconfig
export const clusterName = cluster.name;
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("gkeK8s", {
    kubeconfig: kubeconfig,
});

// Deploy the bytesafe-ce Helm chart using the Helm Chart resource.
const bytesafeChart = new k8s.helm.v3.Chart("bytesafe-ce", {
    chart: "bytesafe-ce",
    version: "YOUR_CHART_VERSION",  // Specify the chart version
    // Add any required custom values for the bytesafe-ce configuration below.
    values: {},  
}, { provider: clusterProvider });

// Export the Helm chart status
export const bytesafeChartStatus = bytesafeChart.status;
```

To run this program:

1. Save the code in a file with a `.ts` extension, for example `deploy_bytesafe_ce.ts`.
2. Run `pulumi up` from the command line in the same directory as the code.

Make sure you have Pulumi installed and configured, as well as access to the GCP project where you're deploying the resources. The `bytesafe-ce` Helm chart must be available in a Helm repository that has been added to your environment; ensure this step is done if the chart is not in the default Helm chart repositories.

This program is a basic template and might need adjustments based on the specific requirements of the `bytesafe-ce` Helm chart and its dependencies.
