Deploy the aws-otel-collector helm chart on Kubernetes

Question

Pulumi · Accepted Answer

Deploying the `aws-otel-collector` helm chart on a Kubernetes cluster can be done using Pulumi's Kubernetes provider. The `aws-otel-collector` is an AWS OpenTelemetry Collector that can collect metrics and traces. Helm charts provide an easy way to package and deploy applications on Kubernetes. Here's a detailed breakdown of how you can achieve this:

1. **Set up a Kubernetes Cluster**: Before deploying the Helm chart, you need a running Kubernetes cluster. You can create a new one or use an existing one.
2. **Configure Pulumi's Kubernetes Provider**: To interact with the Kubernetes cluster, you need to set up the Kubernetes provider which allows Pulumi to perform actions on the Kubernetes API.
3. **Add the Required Helm Repository**: Helm charts are often stored in repositories. You need to add the repository where the `aws-otel-collector` chart is hosted.
4. **Deploy the `aws-otel-collector` Helm Chart**: With Pulumi's Kubernetes provider, we'll define a Helm chart resource that references the `aws-otel-collector` chart and deploy it to the cluster.

Below is a Pulumi program written in TypeScript that accomplishes the deployment of the `aws-otel-collector` Helm chart on Kubernetes:

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

// Step 1: Provide access to your Kubernetes Cluster
// This assumes you have a kubeconfig file correctly configured in your environment,
// or other authentication mechanisms set up for Kubernetes.

// Step 2: Configure Pulumi to use the Kubernetes provider
const provider = new k8s.Provider("k8s-provider", {
    // You can specify the kubeconfig explicitly; otherwise, it is taken from the environment
    // kubeconfig: process.env.KUBECONFIG,
});

// Step 3: Add the repository that contains the aws-otel-collector Helm chart
// Note that you should replace `REPOSITORY_URL` with the actual URL of the chart repository
const otelRepo = new k8s.helm.v3.Repository("otel-repo", {
    name: "aws-observability",
    repo: "https://aws-observability.github.io/aws-otel-helm-charts",
}, { provider });

// Step 4: Deploy the aws-otel-collector Helm chart
const awsOtelCollectorChart = new k8s.helm.v3.Chart("aws-otel-collector", {
    // The chart version, values etc., can be customized as per the Helm chart's documentation.
    // Repo name from our repository resource above
    repo: otelRepo.name,
    chart: "aws-otel-collector",
    namespace: "default",  // specify the namespace if needed
    values: {
        // Specify any values required for configuring the aws-otel-collector.
        // These are chart specific and can be found in the chart's documentation.
    },
}, { provider });

// To interact with the deployed Helm chart, you may need to export certain values, such as ingress URLs or service endpoints.
export const collectorServiceName = awsOtelCollectorChart.getResourceProperty("v1/Service", "aws-otel-collector", "metadata").apply(m => m.name);
```

This program is a starting point for deploying the `aws-otel-collector`. Make sure to adjust the `values` field to match the configuration that you require for your specific setup. The `aws-otel-collector` chart's documentation will provide all the necessary details on configurable parameters.

You will need to have Pulumi installed and configured for use with your desired cloud provider. Ensure that the Kubernetes cluster is properly configured in your environment (e.g., with `kubectl`) so that Pulumi can interact with it. After you run this Pulumi program, the `aws-otel-collector` will be deployed to your Kubernetes cluster.

Remember to run `pulumi up` from your terminal to apply this Pulumi program, which will prompt you to review the changes before actually applying them to your Kubernetes cluster.
