Deploy the konnectivity-agent helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `konnectivity-agent` helm chart on Kubernetes using Pulumi, we'll use the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider. This allows us to specify Helm charts directly in our Pulumi code, leveraging Helm's packaging functionality within our Kubernetes infrastructure provisioning.

The `kubernetes.helm.v3.Chart` resource takes several parameters that describe the Helm chart you want to deploy:
- `chart`: The name of the chart in the Helm repository.
- `version`: The version of the chart to deploy.
- `namespace`: The Kubernetes namespace to deploy the chart into. If not specified, the chart will be deployed in the default namespace.
- `values`: A set of configuration values for the Helm chart. These are equivalent to what you would normally put in a `values.yaml` file or specify with `--set` on the command line with Helm.

The following program in TypeScript shows how to use Pulumi to deploy the `konnectivity-agent` Helm chart:

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

// Create a Kubernetes Namespace
const ns = new k8s.core.v1.Namespace("ns", {
  metadata: {
    name: "konnectivity-ns",
  },
});

// Deploy the konnectivity-agent Helm chart into the created namespace
const konnectivityAgentChart = new k8s.helm.v3.Chart("konnectivity-agent", {
  chart: "konnectivity-agent",
  version: "x.y.z", // Replace with the appropriate chart version
  namespace: ns.metadata.name,
  // Define any custom values for the Helm chart
  values: {
    // ... specify any specific values for your konnectivity-agent deployment
  },
});

// Export the namespace name
export const namespaceName = ns.metadata.name;
```

In this program, replace `x.y.z` with the actual version of the `konnectivity-agent` chart you want to deploy. The `values` object is where you can specify custom configuration values for the chart. These would be specific to the `konnectivity-agent` chart and the exact settings would depend on the chart's available options.

To use this Pulumi program, you would save it in a file with a `.ts` extension (e.g., `index.ts`). Ensure that you have Pulumi installed and the Kubernetes provider configured for your target cluster.

Once the file is saved, you can deploy it using the Pulumi CLI:

1. Initialize a new Pulumi stack, if you haven't already:
   ```bash
   pulumi stack init dev
   ```

2. Install the necessary NPM packages:
   ```bash
   npm install
   ```

3. Preview the deployment:
   ```bash
   pulumi preview
   ```

4. If everything looks good, deploy the chart to your cluster:
   ```bash
   pulumi up
   ```

Please ensure you've set up your Kubernetes context correctly so that Pulumi can communicate with your cluster. The context should be pointing to the cluster where you want to deploy the `konnectivity-agent`.
