Deploy the octavia helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the Octavia Helm chart on AWS Elastic Kubernetes Service (EKS), you would need to follow these steps:

1. Set up an EKS cluster where the Helm chart will be deployed. This involves creating an EKS cluster along with the necessary node groups that will host the Kubernetes pods.
2. Once the cluster is ready and `kubectl` is configured to communicate with the cluster, you can use Pulumi's Kubernetes provider to interact with the cluster and deploy Helm charts.

The program below is written in TypeScript, and it will use Pulumi to create an EKS cluster and deploy the Octavia Helm chart. Before we proceed to the program, ensure you have installed Pulumi CLI, set up AWS credentials on your system, and also installed the necessary Pulumi packages using `npm` or `yarn`.

Here is a Pulumi TypeScript program that creates an EKS cluster and deploys the Octavia Helm chart on it:

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

// Create an EKS cluster with the desired configuration
const cluster = new eks.Cluster("my-eks-cluster", {
    instanceType: "t2.medium", // Choose the appropriate instance type for your needs
    desiredCapacity: 2,        // Define the number of nodes in the cluster
    minSize: 1,                // Define the minimum number of nodes the cluster can scale in to
    maxSize: 3,                // Define the maximum number of nodes the cluster can scale out to
    // Optional: You can specify additional configurations like VPC, subnets, etc.
});

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

// Once the cluster is up and your kubeconfig is configured to use this cluster,
// you can use it to deploy Helm charts.
const octaviaChart = new k8s.helm.v3.Chart("octavia", {
    chart: "octavia",                // Replace this with the correct Helm chart name if different
    version: "1.0.0",                // Replace with the desired chart version
    // Replace with the appropriate repo or define a `repo` that points to where the Octavia Helm chart is stored
    fetchOpts: { repo: "https://example.com/helm-charts" },  
    // Specify the Helm chart values required for Octavia
    values: {
        // Define the values based on Octavia Helm chart options
        // For instance, if the chart requires credentials or specific configurations:
        // api: {
        //   secretKey: "samplekey",
        //   adminToken: "sampletoken",
        //   ...
        // }
    },
}, { provider: cluster.provider }); // This ensures that the Helm chart is installed in the created EKS cluster.

// Run `pulumi up` to deploy the program to AWS, create an EKS cluster, and deploy the Octavia Helm chart.

```

In the code, we are using the `@pulumi/eks` module to create an EKS cluster with a specified instance type and node group configuration. Make sure to customize the instance types, chart, version, and values to match what you need for the Octavia Helm chart. Also, update the repository URL where the Helm chart is located.

After you run this Pulumi program with `pulumi up`, it will deploy an EKS cluster and then the Octavia Helm chart to that EKS cluster. 
Remember to use `pulumi export` to retrieve information like the cluster endpoint and other outputs you might need to interact with your Kubernetes cluster.
