Deploy the motioneye helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the motionEye Helm chart on a Digital Ocean Kubernetes Service (DOKS), you'll first need to create a Kubernetes cluster on Digital Ocean. Once you have the cluster, you can then use the `kubernetes` package to interact with the cluster and deploy Helm charts to it.

Below, I'll guide you through both steps, starting with creating a DigitalOcean Kubernetes cluster using the `digitalocean.KubernetesCluster` resource and then deploying the motionEye Helm chart using the `kubernetes.helm.v3.Chart` resource.

First, we will define the cluster. Then, we will configure Pulumi to use Digital Ocean as a provider using your access token. After your Kubernetes cluster is provisioned, the kubeconfig file will be generated. You will need this file to configure the `kubernetes` provider to deploy Helm charts on the cluster.

Here's a program that carries out these steps. Please replace `"your-motioneye-chart-repo"` and `"motioneye"` with the actual Helm chart repo and chart name if they are different.

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

// Step 1: Create a new Digital Ocean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("motioneye-cluster", {
    region: digitalocean.Regions.NYC1, // Select the region where you want your cluster to be deployed
    version: "latest", // Specify the version of Kubernetes you want to deploy
    nodePool: {
        name: "default",
        size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // Choose the size of the nodes (based on your needs)
        nodeCount: 2, // The number of nodes in the Node Pool
    },
});

// Step 2: Get the kubeconfig from the created cluster
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Step 3: Use the kubeconfig to deploy the motioneye helm chart
const motioneyeChart = new kubernetes.helm.v3.Chart("motioneye", {
    chart: "motioneye",
    version: "0.1.0", // Replace with the correct chart version
    fetchOpts: {
        repo: "https://your-motioneye-chart-repo", // Replace with the correct chart repository
    },
}, { provider: new kubernetes.Provider("k8s-provider", { kubeconfig }) });

// Optional: Export the Helm chart status and other outputs you might need
export const chartStatus = motioneyeChart.status;
```

**Explanation:**

1. **DigitalOcean Kubernetes Cluster**:
    - `digitalocean.KubernetesCluster`: This is a Pulumi resource that helps to provision a Kubernetes cluster on Digital Ocean.
    - `region`: The data center where your cluster is deployed.
    - `version`: The version of Kubernetes you want for your cluster (using the `latest` keyword to get the latest stable version)
    - `nodePool`: Information about the nodes that will be part of your cluster, such as the pool name, node size, and node count.

2. **Kubeconfig Generation**:
    - `kubeconfig`: The raw configuration file that allows `kubectl` and other services to communicate with your Kubernetes cluster. We export this so that it can be used by Pulumi for deploying applications to the cluster.

3. **Helm Chart for motionEye**:
    - `kubernetes.helm.v3.Chart`: This is a Pulumi resource provided by the Kubernetes provider to deploy Helm charts to a Kubernetes cluster.
    - `chart`: The name of the chart you want to deploy, in this case, "motioneye".
    - `version`: The specific version of the Helm chart you wish to deploy.
    - `fetchOpts`: An object that specifies options to fetch the Helm chart, including the repository where the chart is hosted.
    - `provider`: Specifies the Kubernetes provider instance to be used for deploying the chart, which uses the kubeconfig file obtained from the cluster creation step.

After you run this program with Pulumi CLI, a Digital Ocean Kubernetes cluster will be created, and the `motioneye` Helm chart will be deployed to it. You can view the status of the deployment and interact with your Kubernetes cluster using `kubectl`.

Be sure to replace placeholders like `https://your-motioneye-chart-repo` and version numbers with actual values corresponding to the `motioneye` Helm chart repository and the version you want to deploy. If you don't know the exact values, you can usually find them in the documentation or repository of the Helm chart you want to install.
