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

Question

Pulumi · Accepted Answer

To deploy the BackupPC Helm chart on Oracle Kubernetes Engine (OKE), you will need a Kubernetes cluster running on Oracle Cloud Infrastructure (OCI). Below, I will outline the steps and provide a Pulumi program written in TypeScript that will help you accomplish this task.

Setting up the OKE cluster: We will use the oci.ContainerEngine.Cluster resource to create a new Kubernetes cluster. This step involves configuring the cluster with the necessary virtual cloud network (VCN) and options.
Installing the Helm Chart: The Helm Chart for BackupPC will be deployed using the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider. This will manage the release of the BackupPC chart to your OKE cluster.

Here is a step by step Pulumi program to deploy the BackupPC Helm chart on OKE:

import * as pulumi from "@pulumi/pulumi";
import * as oci from "@pulumi/oci";
import * as k8s from "@pulumi/kubernetes";

// Create an OCI provider configuration
const provider = new oci.Provider("provider", {
  region: "us-phoenix-1", // Change to the region where you want to deploy the OKE cluster
});

// Specify the compartment where OKE will be provisioned
const compartmentId = "<Your-OCI-Compartment-ID>";

// Create a virtual cloud network and subnets for the cluster
const vcn = new oci.core.Vcn("okeVcn", {
  compartmentId: compartmentId,
  cidrBlock: "10.0.0.0/16",
  displayName: "oke-vcn",
  dnsLabel: "okevcn",
}, { provider });

const subnet = new oci.core.Subnet("okeSubnet", {
  compartmentId: compartmentId,
  vcnId: vcn.id,
  cidrBlock: "10.0.1.0/24",
  securityListIds: [vcn.defaultSecurityListId],
  displayName: "oke-subnet",
  dnsLabel: "okesubnet",
}, { provider });

// Create an OKE cluster
const cluster = new oci.containerengine.Cluster("okeCluster", {
  compartmentId: compartmentId,
  vcnId: vcn.id,
  kubernetesVersion: "v1.19.7", // Set the version you prefer
  options: {
    serviceLbSubnetIds: [subnet.id],
  },
}, { provider });

// Create a Kubeconfig for the cluster
const kubeconfig = pulumi.all([cluster.id, compartmentId]).apply(([clusterId, compartmentId]) =>
  oci.containerengine.getClusterKubeconfig({
    clusterId: clusterId,
    compartmentId: compartmentId,
  }, { async: true })
);

// Create a Kubernetes provider instance using the kubeconfig
const k8sProvider = new k8s.Provider("okeK8s", {
  kubeconfig: kubeconfig.apply(c => c.content),
}, { dependsOn: cluster });

// Deploy the BackupPC Helm chart
const backuppcChart = new k8s.helm.v3.Chart("backuppc", {
  chart: "backuppc",
  version: "4.4.0", // Specify the version of the chart you want to deploy
  namespace: "default",
  fetchOpts: {
    repo: "http://your-helm-chart-repo/", // Specify the Helm chart repository
  },
}, { provider: k8sProvider });

// Export the cluster name and the BackupPC chart status
export const clusterName = cluster.name;
export const backuppcChartStatus = backuppcChart.status;

Make sure to replace <Your-OCI-Compartment-ID> with the actual compartment ID and specify the correct region, Kubernetes version, and Helm chart version and repository URL in the above code. The Kubernetes provider will use the kubeconfig from the created OKE cluster to deploy the BackupPC chart. After running this program with Pulumi, you will have the OKE cluster running with BackupPC deployed via Helm.

To run this program: save the code to a file named index.ts, install the necessary dependencies, and then execute it using the Pulumi CLI.

# Install Pulumi CLI and the necessary dependencies
npm install @pulumi/pulumi @pulumi/oci @pulumi/kubernetes

# Login to your Pulumi account
pulumi login

# Create a new Pulumi stack
pulumi stack init dev

# Review the program to be deployed
pulumi preview

# Deploy the stack
pulumi up

This will provision the resources on OCI and deploy the BackupPC Helm chart. The output of pulumi up will display the status of the deployment.
