Deploy the ztncui helm chart on Oracle Kubernetes Engine (OKE)

To deploy the ztncui Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you will need to perform a series of steps. These include setting up your OKE cluster, configuring your Kubernetes provider to interact with your OKE cluster, and then using the Helm chart resource to deploy ztncui.

Here's a step-by-step breakdown of the process:

1. Set up your OKE Cluster: To create a Kubernetes cluster in Oracle Cloud Infrastructure (OCI), you'll use the oci.ContainerEngine.Cluster resource. This will provision an OKE cluster for you.

2. Configure Kubernetes Provider: After your cluster is set up, you will need to configure the Pulumi Kubernetes provider to use the kubeconfig from your OKE cluster. This provider enables Pulumi to perform operations on the Kubernetes API server.

3. Deploy Helm Chart: Once you have a Kubernetes provider configured, you can proceed to deploy the Helm chart with ztncui. Pulumi's kubernetes.helm.v3.Chart resource takes care of deploying Helm charts.

Below is a TypeScript program that performs these steps using Pulumi. The program assumes you have set up Pulumi and authenticated with OCI.

import * as pulumi from "@pulumi/pulumi";
import * as oci from "@pulumi/oci";
import * as kubernetes from "@pulumi/kubernetes";

// Create an Oracle Kubernetes Engine (OKE) cluster
const cluster = new oci.containerengine.Cluster("ztncuiCluster", {
    /* provide your required configuration for the OKE cluster */
});

// Obtain the kubeconfig for the OKE cluster
const kubeconfig = cluster.kubeconfig.apply(JSON.parse);

// Configure the Kubernetes provider for Pulumi to manage resources in the OKE cluster
const provider = new kubernetes.Provider("okeK8sProvider", {
    kubeconfig: kubeconfig.rawConfig,
});

// Using the kubernetes provider, deploy the ztncui helm chart
const chart = new kubernetes.helm.v3.Chart("ztncui", {
    chart: "ztncui",
    // The repository where the chart can be found. You may need to replace this with the correct repository for ztncui.
    repo: "http://example.com/charts", 
    /* set additional configurations for the chart if needed */
}, { provider });

// Export the base URL for the ztncui service
export const ztncuiUrl = pulumi.interpolate `http://${chart.getResourceProperty("v1/Service", "ztncui", "status").apply(status => status.loadBalancer.ingress[0].ip)}`;

Explanation

• oci.containerengine.Cluster: This sets up an OKE cluster. You'll need to provide specific configurations like compartment ID and the network setup as per your requirements within Oracle Cloud Infrastructure.

• kubeconfig: We capture the kubeconfig from the created OKE cluster which allows you to interact with your cluster. This is necessary to set up the Kubernetes provider.

• kubernetes.Provider: This is used to interact with the Kubernetes cluster provisioned by OKE. We specifically supply kubeconfig to authenticate and communicate with the cluster.

• kubernetes.helm.v3.Chart: This resource is used to deploy Helm charts. You provide the chart name and repository to locate ztncui. Please note that the repository URL given is a placeholder, and you'll need to replace it with the actual chart repository.

• ztncuiUrl: Finally, we export the URL where the ztncui service is exposed. This allows you to access ztncui from your browser. The exact way to retrieve the URL may differ based on how the service for ztncui is exposed (via LoadBalancer, NodePort, etc.), and you might need to adjust the exported URL accordingly.

Remember to replace placeholders and configure further based on your specific setup and requirements. This program is a starting point and might require fine-tuning to fit into your environment policy and the Helm chart's settings.

After applying this Pulumi program, it will set up an OKE cluster, configure Kubernetes to interact with it, and deploy the ztncui Helm chart. You can run the Pulumi program using the Pulumi CLI with the command pulumi up, after you've ensured that the prerequisites are in place.
