Deploy the oci-registry helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the `oci-registry` Helm chart on Digital Ocean Kubernetes Service using Pulumi, we will go through a few steps. I'll provide a detailed explanation of the process and the associated code in TypeScript.

### Setup a DigitalOcean Kubernetes Cluster

First, we will create a Kubernetes cluster in DigitalOcean. This cluster will provide the necessary infrastructure where the Helm chart will be deployed. We need to define the cluster with the desired configurations such as region, version, and node details.

### Install Helm Chart

Once we have the Kubernetes cluster in place, we will need to deploy the Helm chart to the cluster. Since there isn't a specific `oci-registry` Helm chart reference in the Pulumi Registry Results, we'll assume a generic Helm chart installation process that you should modify according to the specific chart you're referring to.

Please ensure that you have the DigitalOcean provider and Kubernetes provider configured in your Pulumi setup.

### Pulumi Program

Now, let's see how to accomplish this using Pulumi. Below is a TypeScript program that will set up a DigitalOcean Kubernetes Cluster and use the Kubernetes provider to install a Helm chart.

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

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc3", // Choose the region that is close to you
    version: "1.21.5-do.0", // Specify the Kubernetes version
    nodePool: {
        name: "default",
        size: "s-2vcpu-2gb", // Choose the size based on your needs
        nodeCount: 2, // Number of nodes in the node pool
    },
});

// Export the kubeconfig to access the cluster
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Create a Helm Release for the oci-registry chart
const ociRegistryRelease = new k8s.helm.v3.Release("oci-registry-release", {
    chart: "oci-registry", // Replace with the actual Helm chart name
    version: "0.1.0", // Replace with the chart version you wish to deploy
    namespace: "default", // Deploy to the default namespace or specify another
    repositoryOpts: {
        repo: "https://charts.example.com/", // Replace with the Helm chart repository URL
    },
    // Provide any custom values to the chart
    values: {
        // ... custom chart values go here
    },
}, { provider: new k8s.Provider("k8s-provider", {kubeconfig: cluster.kubeConfigs[0].rawConfig}) });

// Export the endpoint of the Kubernetes cluster
export const kubeClusterEndpoint = cluster.endpoint;
```

In this program:

- We create a Kubernetes cluster in the specified region using the `digitalocean.KubernetesCluster` class. Adjust the region, version, and node pool configuration according to your requirements.
- We export the `kubeconfig` for accessing the created Kubernetes cluster.
- We deploy the `oci-registry` Helm chart (note that you need to replace `"oci-registry"` and the repo URL with the actual chart name you intend to deploy and its source).
- The `k8s.helm.v3.Release` class is used to instruct Pulumi on deploying the Helm chart to the Kubernetes cluster. Here, you will need to specify the namespace, chart version, and any custom values your chart requires.

### Next Steps

After running this Pulumi program with the `pulumi up` command, you will have a Kubernetes cluster running in DigitalOcean and your OCI Registry Helm Chart will be deployed onto your cluster.

Please ensure that you replace placeholder values like the Helm chart name, version, and repository URL with the actual details relevant to the oci-registry Helm chart you want to deploy. If the `oci-registry` chart has any specific configuration parameters, make sure to add them in the `values` section of the Helm release.

For more detailed documentation on the resources used:

- For the `digitalocean.KubernetesCluster`, refer to the [Pulumi DigitalOcean documentation](https://www.pulumi.com/registry/packages/digitalocean/api-docs/kubernetescluster/).
- For deploying Helm charts with Pulumi's Kubernetes provider, check out the [Pulumi Helm documentation](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/release/).

Remember that you will have to have Pulumi installed, along with the necessary provider plugins and configured cloud credentials, for this code to work. If you encounter any issues or have any questions, please explore the Pulumi documentation or reach out to the community for support.
