Deploy the openvpn-as helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `openvpn-as` Helm chart on AWS EKS using Pulumi, you'll want to perform the following steps:

1. Set up an EKS cluster in your AWS account.
2. Install the `openvpn-as` Helm chart into the EKS cluster.

Here's how you can create an EKS cluster and then deploy the `openvpn-as` Helm chart into that cluster using Pulumi with TypeScript.

Firstly, you'll need to create a new EKS cluster. You can do this with the `@pulumi/eks` package, which simplifies creating EKS clusters.

Next, you will deploy the `openvpn-as` Helm chart using the `@pulumi/kubernetes` package that allows for Helm chart deployments.

Please ensure you have the AWS and Kubernetes configurations set up in your Pulumi environment before running the program.

To explain the Pulumi code in more detail:

- **eks.Cluster**: It creates an EKS cluster in your AWS account.
- **kubernetes.Provider**: This is the Kubernetes provider that uses the kubeconfig of the created EKS cluster for deploying services on it.
- **kubernetes.helm.v3.Chart**: This creates a Helm chart deployment in your cluster.

Here is the TypeScript code for the deployment:

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as eks from '@pulumi/eks';
import * as aws from '@pulumi/aws';
import * as k8s from '@pulumi/kubernetes';

// Create an EKS cluster.
const cluster = new eks.Cluster('my-cluster', {
    instanceType: 't2.medium',
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 3,
    storageClasses: 'gp2',
    deployDashboard: false,
});

// Export the clusters' kubeconfig.
export const kubeconfig = cluster.kubeconfig;

// Create a Kubernetes provider instance that uses our EKS cluster from above.
const k8sProvider = new k8s.Provider('k8s-provider', {
    kubeconfig: cluster.kubeconfig,
});

// Now we use the Helm Chart resource to deploy OpenVPN.
const openvpnChart = new k8s.helm.v3.Chart('openvpn-as', {
    chart: 'openvpn-as',
    version: '5.1.0', // specify the exact chart version
    namespace: 'default', // specify the namespace to deploy into
    // Values for the chart can be provided as an object.
    values: {
        // Here you normally provide configuration values for the OpenVPN chart.
        // Check the OpenVPN chart's documentation for the available values: https://artifacthub.io/packages/helm/openvpn/openvpn-as
    },
}, { provider: k8sProvider });

// When running `pulumi up`, the code above will automatically configure the specified AWS region, create an EKS cluster, and deploy the OpenVPN Helm chart to it.
```

Don't forget to replace `'5.1.0'` with the actual version of the `openvpn-as` Helm chart that you want to deploy.

Before running your Pulumi program, make sure you have Pulumi installed, AWS CLI configured with access credentials, `kubectl` installed, and the AWS provider set up with your credentials.

Once you run your Pulumi program with `pulumi up`, it will provision the necessary resources on AWS and deploy the OpenVPN server onto your EKS cluster. You can then manage and access your OpenVPN server using standard Kubernetes tools like `kubectl`.
