Deploy the oidc-proxy helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the oidc-proxy Helm chart on the Digital Ocean Kubernetes Service using Pulumi, you'll follow these general steps:

1. **Create a Kubernetes cluster** in DigitalOcean. You will define a cluster resource using the `digitalocean.KubernetesCluster` resource which sets up a managed Kubernetes cluster.
   
2. **Install the Helm Chart** on the Kubernetes Cluster. To do this, you will use the `kubernetes.helm.v3.Chart` resource from the Kubernetes Pulumi provider which allows you to deploy Helm charts to your Kubernetes cluster.

3. **Configure Pulumi for DigitalOcean**. Ensure that you have set up the required Pulumi configuration for DigitalOcean, such as the access token.

Make sure you have DigitalOcean access credentials and Pulumi installed and configured correctly. You'll need to provide the `accessToken` either through the Pulumi config set or have it set in your environment variables.

Now, let's proceed with the program that will deploy the oidc-proxy 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: 'nyc1', // You can choose your preferred region here
    version: 'latest', // Specify a version or use "latest"
    nodePool: {
        name: 'default',
        size: 's-2vcpu-2gb', // This is the smallest node size. Change as needed.
        nodeCount: 2, // Adjust the node count based on your needs
    },
});

// Export the DigitalOcean kubeconfig to interact with your cluster.
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Create a Kubernetes provider instance using the kubeconfig from the cluster we just created
const k8sProvider = new k8s.Provider('k8s-provider', {
    kubeconfig: kubeconfig,
});

// Deploy the oidc-proxy Helm chart to the cluster
const helmRelease = new k8s.helm.v3.Chart('oidc-proxy', {
    chart: 'oidc-proxy', // The name of the chart. Change if the chart name is different.
    version: '0.1.0', // The version of the chart, adjust as needed.
    // If your chart is from a custom repository, specify `repo` and `fetchOpts` as required.
}, { provider: k8sProvider });

// Export the Helm release status
export const helmReleaseStatus = helmRelease.status;
```

This Pulumi program performs the following actions:

1. It declares a DigitalOcean Kubernetes cluster using the `digitalocean.KubernetesCluster` resource. The cluster is configured with a node pool that specifies the size of the nodes and the number of nodes in the pool. Adjust these to fit your needs.

2. It exports the kubeconfig for the DigitalOcean cluster as a stack output, which you can use with `kubectl` to interact with your cluster.

3. It sets up a Pulumi Kubernetes provider that uses kubeconfig from the DigitalOcean cluster.

4. It deploys the oidc-proxy Helm chart to the cluster using the `k8s.helm.v3.Chart` resource. Make sure to specify the correct version and repository of the oidc-proxy chart you wish to deploy. If the Helm chart is hosted on a custom Helm repository, you will need to set the `repo` attribute to the repository URL and include the `fetchOpts` if there's any additional fetching configuration needed.

After defining this Pulumi program in a TypeScript file, you can deploy it by running `pulumi up` in your terminal. This command initiates the provisioning of the resources as defined in your code. After the command runs, you should see the status of the Helm release as output, indicating the deployment of the oidc-proxy Helm chart.
