Deploy the orangehrm helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the OrangeHRM Helm chart on Digital Ocean Kubernetes service, you need to perform several steps using Pulumi. First, you'll create a Kubernetes cluster on Digital Ocean. Following that, you'll deploy the OrangeHRM Helm chart onto the created Kubernetes cluster. Below, we will outline these steps in detail with a Pulumi TypeScript program.

### Step 1: Create a Digital Ocean Kubernetes Cluster

You'll start by defining a new Kubernetes cluster resource with the desired configurations like region, node size, and so on. Pulumi provides a DigitalOcean package for managing resources on Digital Ocean, and we will utilize the `digitalocean.KubernetesCluster` class from this package to create the cluster.

### Step 2: Deploy the Helm Chart

Once the Kubernetes cluster is created, you'll deploy the OrangeHRM Helm chart using the `kubernetes.helm.v3.Chart` class from the Pulumi Kubernetes provider. This class allows you to deploy Helm charts into a Kubernetes cluster. Pulumi will handle fetching the Helm chart from the specified repository and deploying it using the provided configurations.

Here is how you can orchestrate the whole setup:

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

const projectName = "orangehrm-deploy";

// Step 1: Create a Digital Ocean Kubernetes Cluster
const cluster = new digitalocean.KubernetesCluster(projectName, {
    // Configure the region, version, node size, etc.
    region: digitalocean.Regions.NYC3,
    version: "latest",
    nodePool: {
        name: "default-pool",
        size: "s-2vcpu-2gb",
        nodeCount: 2, // You can specify the desired node count for the pool
    },
});

// Export the cluster's kubeconfig and name
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
export const clusterName = cluster.name;

// Step 2: Deploy the OrangeHRM Helm chart
// Ensure the K8s provider instance uses the created cluster's kubeconfig
const k8sProvider = new kubernetes.Provider(projectName, {
    kubeconfig: kubeconfig,
});

// Define the OrangeHRM Helm Chart from its repository
const orangeHrmChart = new kubernetes.helm.v3.Chart("orangehrm", {
    chart: "orangehrm",
    version: "4.2.5", // Specify the chart version you want to deploy
    fetchOpts: {
        repo: "https://charts.bitnami.com/bitnami", // The repository URL where the chart is located
    },
}, { provider: k8sProvider });

// Export the status and the endpoint when available
orangeHrmChart.status.isReady.apply(isReady => {
    if (isReady) {
        pulumi.log.info(`OrangeHRM Chart is deployed.`);
    } else {
        pulumi.log.info(`OrangeHRM Chart installation in progress.`);
    }
});

// The following is optional: If you need the public endpoint of the service, you can add a query here to fetch it.
// For example, you might need to use kubernetes.core.v1.Service to get the LoadBalancer's ingress.

// Make sure to replace `orangehrm` below with the correct release name and `service` with the actual resource type and name as per the deployed chart:
const service = orangeHrmChart.getResource("v1/Service", "orangehrm-orangehrm");
export const orangeHrmEndpoint = service.status.loadBalancer.ingress[0].ip;
```

In this program, we first declare a Digital Ocean Kubernetes cluster with the necessary specifications and export the resulting kubeconfig. This kubeconfig is required for Pulumi to interact with the Kubernetes cluster.

Next, we create an instance of the Pulumi Kubernetes provider, specifying the kubeconfig obtained from the newly created cluster so that Pulumi can manage resources within this cluster.

Then, we define a `Chart` resource to deploy OrangeHRM using its Helm chart from the Bitnami chart repository. We've used a specific version `4.2.5`, but you should replace this with the latest or the desired chart version you want to use.

Finally, we export a potential endpoint for the deployed OrangeHRM service. Note this will only apply if the service is of type LoadBalancer, and the Helm chart we deploy must be configured to expose such a service. If the Helm chart
