Deploy the kommander-thanos helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the kommander-thanos Helm chart on AWS EKS, you need to complete a few high-level steps. First, you'll create an EKS cluster and configure your Kubernetes environment to work with it. Then, you'll deploy the Helm chart to your EKS cluster.

Here's a detailed walkthrough of each step involved, followed by a program written in TypeScript using Pulumi to accomplish these tasks.

### Step 1: Create an EKS Cluster

We will utilize Pulumi's EKS package, which provides higher-level abstractions for creating and managing EKS clusters. The `eks.Cluster` class makes it easy to create an EKS cluster and returns a kubeconfig that can be used with kubectl or other Kubernetes management tools.

### Step 2: Deploy the Helm Chart

Once we have a Kubernetes cluster, we will deploy our Helm chart. Pulumi's Kubernetes provider also supports deploying Helm charts with the `kubernetes.helm.v3.Chart` resource.

The Helm chart deployment will need the chart name (`kommander-thanos` in this case) and potentially any values you'd like to override in the default Helm chart. Those values can usually be found in the chart's `values.yaml` file or in the documentation for the chart.

### Pulumi Program for Deploying kommander-thanos on AWS EKS

Now let's walk through the program code.

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

// Create an EKS cluster with the correct roles and settings applied
const cluster = new eks.Cluster('my-eks-cluster', {
    // Specify any specific settings here (e.g., desired capacity, instance types, etc.)
});

// Export the kubeconfig to access the cluster
export const kubeconfig = cluster.kubeconfig;

// Once we have a cluster, we can deploy a Helm chart.
// Ensure that the Helm chart and repository are accessible
// and that any required configurations are known.
const kommanderThanosChart = new k8s.helm.v3.Chart('kommander-thanos', {
    chart: 'kommander-thanos',
    version: 'x.x.x', // replace with the actual chart version
    fetchOpts: {
        repo: 'https://helm-repository-where-chart-is-located/', // replace with the actual Helm repository URL
    },
    // If needed, supply additional configurations 
    // values: { ... }
}, { provider: cluster.provider });

// At this point, you can export any resources you might need to access
// For instance, if the chart exposes some services with external endpoints:
export const thanosServiceUrl = cluster.getKubeconfig().then(kc =>
    k8s.core.v1.Service.get('thanos-service', pulumi.output('thanos-serviceName'), { kubeconfig: kc })).status.loadBalancer.ingress[0].hostname;
```

After executing this Pulumi program, it will set up an EKS cluster and deploy the `kommander-thanos` Helm chart onto the cluster.

Keep in mind that Helm charts may have dependencies on specific Kubernetes resources or configurations. Ensure you have reviewed the chart's documentation and adapted the program with any required values or settings specific to `kommander-thanos`.

Lastly, since we are using Typescript and Pulumi, you can test and deploy this program using the Pulumi CLI tools. Define your AWS credentials and then run `pulumi up` to start provisioning your infrastructure.
