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

Question

Pulumi · Accepted Answer

To deploy the OrientDB Helm chart on Oracle Kubernetes Engine (OKE), we will follow these steps:

1. **Set up OKE Cluster**: We will create an OKE cluster using Pulumi's `oci.ContainerEngine.Cluster` resource. This will provision the necessary Kubernetes cluster infrastructure on Oracle Cloud.

2. **Deploy Helm Chart**: Once the cluster is up and running, we utilize Pulumi's `kubernetes.helm.sh/v3.Release` resource to deploy the OrientDB Helm chart onto our Kubernetes cluster in OKE.

Below is a detailed Pulumi program written in TypeScript that accomplishes this. You will find explanations before and after each segment of the code. Make sure to have Pulumi CLI installed, and you are logged in to your Oracle Cloud account before running this program.

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

// Ensure you have the necessary OCI configuration for Pulumi to communicate with your Oracle Cloud account.
// These configurations typically include tenancy OCID, user OCID, fingerprint, and your region.
// They are loaded from environment variables or the OCI config file.

// First, we'll create an Oracle Container Engine for Kubernetes (OKE) cluster
const cluster = new oci.ContainerEngine.Cluster("orientdb-cluster", {
  // Specify the compartment OCID where you want to launch the cluster
  compartmentId: pulumi.interpolate`${oci.config.tenancyOcid}`,

// Provide a name for the cluster
  name: "orientdb-cluster",

// Choose your Kubernetes version
  kubernetesVersion: "v1.21.5",

// Define the settings for the OKE cluster, such as network configuration, VM shape, etc.
  options: {
    // ... Add your specific OKE options here
  },

// More configuration can be added as needed
});

// Once the cluster is created, we need to set up the Kubernetes provider with the kubeconfig
const k8sProvider = new k8s.Provider("k8s-provider", {
  kubeconfig: cluster.kubeconfig, // This assumes the kubeconfig property is available on the cluster object
});

// Now we'll deploy the OrientDB Helm chart to our cluster
const orientDbRelease = new k8s.helm.sh.v3.Release("orientdb-helm-release", {
  // Specify the release name and namespace (if needed)
  name: "orientdb-release",
  namespace: "default", // Default namespace, change if you want to deploy it elsewhere

// Define the chart details for OrientDB
  chart: "orientdb",
  repositoryOpts: {
    repo: "https://helm.orientdb.com/", // Replace with actual OrientDB Helm chart repo if different
  },

// Set any values in the Helm chart, such as passwords and configurations
  values: {
    //... Define necessary chart values here
  },
}, { provider: k8sProvider }); // Make sure to use the Kubernetes provider we instantiated earlier

// Export the cluster name and chart release details
export const clusterName = cluster.name;
export const orientDbReleaseName = orientDbRelease.metadata.apply(meta => meta.name);

```

### How to Use This Program

1. **Install Pulumi CLI**: Make sure you have the Pulumi CLI installed and configured for TypeScript.

2. **Configure OCI Credentials**: Set up and authenticate with your Oracle Cloud Infrastructure account. Specify your tenancy OCID, user OCID, and private key information for Pulumi to authenticate with your Oracle Cloud account.

3. **Set Required Parameters**: Replace any placeholder values with actual data, such as the compartment ID, Kubernetes version, and chart values. Make sure you customize the cluster name, region, and any specific OKE options.

4. **Run the Program**: Deploy the program using the Pulumi CLI with the following commands:

```sh
   pulumi stack init <stack-name>
   pulumi up
   ```

This will provision the resources defined in your Pulumi program. Follow the CLI prompts to execute the changes.

5. **Access OrientDB**: Once the deployment is successful, you can access OrientDB via Kubernetes services or ingress resources as defined by your chart configurations.

To summarize:
- We define a Kubernetes cluster in OKE with `oci.ContainerEngine.Cluster`.
- We deploy a Helm Chart for OrientDB using `k8s.helm.sh/v3.Release`.
- The cluster's kubeconfig is used to configure the Kubernetes provider for Pulumi.
- Chart values and repository details are specified according to the OrientDB Helm chart.
