Deploy the ldap-account-manager helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `ldap-account-manager` Helm chart on AWS EKS, we'll walk through the following steps:

1. Create an EKS cluster.
2. Configure the Kubernetes provider to deploy resources to the EKS cluster.
3. Deploy the `ldap-account-manager` using the Helm chart.

We'll use Pulumi's EKS package to create the cluster. This package simplifies the process by abstracting away some of the underlying resources needed to set up an EKS cluster. Once the cluster is up and running, we'll use Pulumi's Helm package to deploy the `ldap-account-manager`.

Before running the Pulumi program, make sure you have the following prerequisites met:

- AWS CLI installed and configured with the necessary access rights.
- Pulumi CLI installed and logged in to the Pulumi service.
- Helm CLI installed (only required if you need to fetch or customize the Helm chart outside of Pulumi).
- `kubectl` CLI installed if you need to interact with the cluster directly.

Now, let's proceed with the Pulumi TypeScript program to deploy the `ldap-account-manager`:

```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 with the default configuration.
const cluster = new eks.Cluster("my-cluster", {
    instanceType: "t2.medium",
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 2,
    storageClasses: "gp2",
    deployDashboard: false,
});

// Export the kubeconfig so that we can use 'kubectl' outside of Pulumi to interact with our EKS cluster.
export const kubeconfig = cluster.kubeconfig.apply(JSON.stringify);

// Now we set up the Pulumi Kubernetes provider using the kubeconfig created from the EKS cluster.
// This provider is used to deploy Helm charts to the cluster.
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig,
});

// Deploy the `ldap-account-manager` Helm chart into our EKS cluster.
const ldapAccountManagerChart = new k8s.helm.v3.Chart("ldap-account-manager", {
    chart: "ldap-account-manager",
    fetchOpts:{
        repo: "https://example-repository.com/charts", // Replace with the actual Helm chart repository
    },
    // Pass the values for the ldap-account-manager chart here, as per the chart's requirements.
    values: {
        // For example (this is not a real configuration, replace with actual values)
        // image: "ldapaccountmanager/lam",
        // tag: "latest",
    },
}, { provider: k8sProvider });

// Optionally, you can export the Helm release's status.
export const ldapAccountManagerStatus = ldapAccountManagerChart.status;
```

In this Pulumi program:
- We initialize a new EKS cluster using `eks.Cluster`. We specify the desired capacity, minimum and maximum size, the instance type, as well as additional configuration such as whether to deploy the Kubernetes dashboard.
- The `kubeconfig` is exported for potential use with `kubectl`. This is helpful for debugging or managing the cluster outside Pulumi.
- We create a `k8s.Provider` using the kubeconfig which points Pulumi to our new EKS cluster.
- We deploy the `ldap-account-manager` Helm chart using `k8s.helm.v3.Chart`. You need to replace the `repo` URL with the actual Helm chart repository URL that hosts the `ldap-account-manager` chart.

To run this Pulumi program:

1. Save the code to a file named `index.ts`.
2. Run `pulumi up` to create the resources. This command shows you what it's going to do before it does it, and then a second time for confirmation.
3. If everything looks good, proceed with the deployment.

After deployment, Pulumi will print the output of any exported variables. You can access the EKS cluster using `kubectl` with the exported kubeconfig as needed for any further configurations or inspections.

Keep in mind the actual values and configuration for the LDAP Account Manager deployment may differ based on your needs and the specific Helm chart used. Always refer to the official Helm chart documentation for the accurate configuration options.
