Deploy the jaeger-all-in-one-opentelemetry helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Jaeger all-in-one OpenTelemetry Helm chart on a Kubernetes cluster using Pulumi, you will perform the following steps:

1. **Setting up a Pulumi Project**: Before accessing the code, you'll need to set up a Pulumi project and install the necessary dependencies.

2. **Adding the Kubernetes Provider**: In Pulumi, you need to import the Kubernetes provider, which lets you interact with your Kubernetes cluster.

3. **Deploying the Helm Chart**: Use the `kubernetes.helm.v3.Chart` resource to deploy the Jaeger all-in-one OpenTelemetry Helm chart.

Here's the complete Pulumi program written in TypeScript:

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

// Initialize a Kubernetes provider that uses the current context
// from your kubeconfig file, which Pulumi automatically picks up.
const provider = new kubernetes.Provider("provider", {});

// Deploy the jaeger-all-in-one-opentelemetry Helm chart using pulumi/kubernetes.
const jaegerChart = new kubernetes.helm.v3.Chart("jaeger-all-in-one-opentelemetry", {
    // Specify the chart version you want to deploy.
    version: "2.19.0", // Replace with the desired version
    // Specify the chart and the repository where the chart is located.
    chart: "jaeger-all-in-one",
    repo: "jaegertracing", // The Helm repository hosting the jaeger-all-in-one chart
    // Optionally, you can provide custom values file or override specific values.
    // For Jaeger, you might not need to override any values for a basic setup.
    values: {}, // Add any required overrides here
}, { provider });

// Export the resulting Resource to track in the Pulumi console or use elsewhere
export const chartName = jaegerChart.metadata.name;
```

Here's what is happening in the program above:

- We import the Kubernetes package from Pulumi, which allows us to interact with Kubernetes objects.
- We create a Kubernetes Provider, which is responsible for authenticating and communicating with your Kubernetes cluster.
- Then, we create an instance of `kubernetes.helm.v3.Chart` to deploy the Helm chart. You need to provide the name of the chart (`jaeger-all-in-one`), the version of the chart (replace `2.19.0` with your desired version if needed), and the Helm repository that hosts the chart.
- Lastly, we export the name of the Helm Release so that it can be easily referenced.

Please make sure you have Pulumi and the Kubernetes provider set up before you run this program. To run the code, use `pulumi up` in the terminal, and Pulumi will execute the deployment to your Kubernetes cluster.

Important notes:
- The version specified should be the one you wish to deploy. You can find the latest chart version in the official [Jaeger Helm Charts repository](https://github.com/jaegertracing/helm-charts).
- The `values` object in the `Chart` resource is where you would override default Helm chart values. In this code, we've left it empty ({}), assuming you want to use the defaults for the Jaeger all-in-one chart. You can customize this based on your requirements.
- It's important to ensure that the Helm chart used is compatible with your Kubernetes cluster version.
- Pulumi's Kubernetes Provider needs access to a Kubernetes cluster. Ensure your `kubeconfig` file has the correct context selected for the cluster you want to deploy to.
