Deploy the kimai-helmchart helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To accomplish the deployment of the Kimai time-tracking helm chart on AWS EKS, we will follow these steps in our Pulumi program:

1. Create an EKS cluster using the `eks.Cluster` resource. This custom Pulumi resource is a high-level abstraction that encapsulates the creation of an EKS cluster, along with its node groups and other associated resources. [Pulumi EKS Cluster Documentation](https://www.pulumi.com/registry/packages/eks/api-docs/cluster/)

2. Deploy the Kimai helm chart on the EKS cluster using the `kubernetes.helm.v3.Chart` resource. The `Chart` resource allows us to deploy Helm charts on a Kubernetes cluster. This step requires the EKS cluster from step 1 to be up and running. [Pulumi Kubernetes Helm Chart Documentation](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/)

Below is a detailed TypeScript program for Pulumi that performs these steps:

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

// Create an EKS cluster.
const cluster = new eks.Cluster("my-eks-cluster", {
    // Specify the desired version of Kubernetes.
    version: "1.21",
    // Specify additional settings here (e.g., node size, scaling options, vpc configuration)
});

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

// Create a provider that uses our EKS cluster's kubeconfig.
const provider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig,
});

// Deploy Kimai helm chart using the providers configuration from our created EKS cluster.
const kimaiChart = new k8s.helm.v3.Chart("kimai", {
    // fetchOpts can be configured to point to a specific Helm repo if necessary.
    chart: "kimai",
    // The version of the chart to deploy. This should be the version number from the Helm chart repository.
    version: "x.y.z", // Please replace x.y.z with the desired chart version
    // Supply appropriate values to configure Kimai chart.
    values: {
        // Add the necessary values for the Kimai chart here.
    },
}, { provider });

// Export any additional resources that might be useful.
// For example, you may want to export the URL of the Load Balancer.
// This would require you to extract the specific service from the helm chart and map it to a LoadBalancer endpoint.

// Note: Make sure to update the Helm chart version and provide configuration values
// according to your requirements and the specifics of the Kimai chart.
```

This Pulumi program defines and creates an EKS cluster and deploys the Kimai time tracking system using its respective Helm chart. Here's a brief explanation of some important components:

- **EKS Cluster**: The `eks.Cluster` creates a managed Kubernetes cluster on AWS EKS. The `version` field specifies which Kubernetes version to use.

- **Kubeconfig**: The `kubeconfig` is the configuration required by `kubectl` and other Kubernetes-aware tooling in order to connect and authenticate to the EKS cluster.

- **Kubernetes Provider**: The `k8s.Provider` references the `kubeconfig` of the provisioned EKS cluster, ensuring that resources are created in the right context.

- **Helm Chart**: The `k8s.helm.v3.Chart` specifies which Helm chart to deploy (in this case "kimai") and its version. The `values` field is used to adjust any configurations required by the chart (like setting up persistence, ingress, choosing a database, etc.).

Before running this Pulumi program, ensure you have Pulumi installed and properly set up with your AWS credentials configured. Also, replace `"x.y.z"` in the `version` field with the version of the Kimai Helm chart you wish to deploy. Finally, you can customize the `values` to suit your specific deployment needs (these value settings are found in the Helm chart's documentation or the `values.yaml` file).
