Deploy the faktory helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the Faktory Helm chart on AWS EKS using Pulumi, we'll need to follow a series of steps:

1. Provision an Amazon EKS cluster using Pulumi's EKS package.
2. Configure Kubernetes to connect to the EKS cluster.
3. Deploy the Faktory Helm chart to the EKS cluster using Pulumi's Kubernetes provider.

Firstly, you'll create an Amazon EKS cluster. EKS is a managed Kubernetes service from AWS that simplifies setting up, running, and maintaining a Kubernetes environment on AWS.

Secondly, you'll configure your Kubernetes provider to connect to the EKS cluster that Pulumi created. This will allow you to interact with the EKS cluster using Kubernetes APIs.

Lastly, you'll use the Helm Chart resource from Pulumi's Kubernetes provider to deploy Faktory. Helm is a package manager for Kubernetes, and a Helm Chart defines a set of resources that can be deployed as a unit. The Faktory Helm chart will typically contain all the necessary Kubernetes resources to run Faktory in your cluster.

Let's get started with the Pulumi program in TypeScript:

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

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

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

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

// Deploy the Faktory Helm chart.
const faktoryChart = new k8s.helm.v3.Chart("faktory", {
    chart: "faktory",
    version: "0.9.0", // Replace with the desired chart version
    namespace: "default", // Specify the namespace if needed
    fetchOpts: {
        repo: "https://helm/charts.faktory.io/", // Replace with the correct Helm repo for Faktory
    },
}, { provider });

// Export the Faktory service endpoint.
export const faktoryEndpoint = faktoryChart.getResourceProperty("v1/Service", "faktory", "status").apply(status => status.loadBalancer.ingress[0].ip);

```

Explanation of the resources:

- `eks.Cluster`: This resource is responsible for creating the EKS cluster. The parameters like `desiredCapacity`, `minSize`, and `maxSize` control the scaling properties of the nodes in your cluster.

- `kubeconfig`: It's an exported output that will hold the kubeconfig information needed to connect to your cluster.

- `k8s.Provider`: This Pulumi Kubernetes provider is configured to communicate with the EKS cluster, using the generated kubeconfig.

- `k8s.helm.v3.Chart`: The Helm Chart resource is used to deploy applications packaged as Helm charts. In this case, it's used to deploy the Faktory Helm chart. You must specify the chart name, version, and optionally, a namespace.

- `faktoryEndpoint`: We are exporting the IP address of Faktory service, presuming a LoadBalancer service is created by the Faktory Helm chart.

**Note:** Make sure to replace `"0.9.0"` with the actual version of the Faktory chart you wish to deploy, and the `repo` URL with the correct Helm repository for Faktory.

Also, ensure that AWS credentials are configured properly on your machine, as Pulumi uses these to provision resources on your behalf.

By running this Pulumi program, it will provision an AWS EKS cluster and deploy the Faktory Helm chart to it automatically. To apply this Pulumi code, you would save the file with a `.ts` extension (for TypeScript), typically as `index.ts`, and run `pulumi up` in the same directory. This will set up AWS EKS and deploy Faktory for you.
