Deploy the airbyte-api-server helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the `airbyte-api-server` helm chart on Linode Kubernetes Engine using Pulumi, you would need to set up a Pulumi program that interacts with Linode to create a Kubernetes cluster and then deploys the helm chart onto that cluster.

Before we dive into the code, let's go over the key steps and resources we will use in our Pulumi TypeScript program:

1. **Linode Kubernetes Cluster**: We'll create a Kubernetes cluster in Linode using the `linode.LKECluster` resource. We need to define the cluster label, region, Kubernetes version, and node pool configuration.
   
2. **Helm Chart**: Once we have our Kubernetes cluster, we will deploy the `airbyte-api-server` helm chart. This will be done using the `kubernetes.helm.v3.Chart` resource, which is part of Pulumi's Kubernetes provider. We need to set the chart name, version, and any values that customize the deployment.

3. **Kubernetes Config**: To interact with the Kubernetes cluster we created, we will be using a KubeConfig obtained from Linode once the cluster is up and running. Pulumi with the Kubernetes provider allows us to use this config to deploy applications within the Kubernetes cluster.

Here is the Pulumi TypeScript program that accomplishes the above:

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as linode from '@pulumi/linode';
import * as kubernetes from '@pulumi/kubernetes';

// Create a Linode Kubernetes Engine (LKE) cluster.
const cluster = new linode.LKECluster("airbyte-cluster", {
    label: "airbyte-cluster",
    region: "us-central", // Pick the right region for you
    k8sVersion: "1.18", // Specify the Kubernetes version
    tags: ["airbyte"],
    // Define at least one node pool to be part of our cluster:
    pool: {
        count: 3, // Number of nodes in the node pool
        type: "g6-standard-2", // Type of nodes to deploy
    },
});

// Get the kubeconfig output from the cluster.
const kubeconfig = pulumi
    .all([cluster.id, cluster.kubeconfig])
    .apply(([_, kubeconfig]) => kubeconfig);

// Set up the Helm chart for Airbyte API Server.
const airbyteApiServerChart = new kubernetes.helm.v3.Chart(
    "airbyte-api-server",
    {
        repo: "airbyte",
        chart: "airbyte",
        version: "0.1.0", // Specify the chart version you wish to deploy
        namespace: "default",
    },
    {
        // Use the kubeconfig from our Linode cluster
        provider: new kubernetes.Provider("airbyte-k8s-provider", {
            kubeconfig: kubeconfig,
        }),
    }
);

// Export the public ClusterIP of the Airbyte service to access the API server.
export const airbyteApiServerIP = airbyteApiServerChart
    .getResourceProperty("v1/Service", "airbyte-api-server", "status")
    .apply(status => status.loadBalancer.ingress[0].ip);
```

This program first creates a Linode Kubernetes Engine (LKE) cluster and then deploys the Airbyte API Server using Helm. We also export the public IP address of the Airbyte service, which is created as part of the Helm chart deployment, so you can access the Airbyte API server.

Please ensure you have the following prerequisites before you run this program:

- Pulumi CLI installed and configured for use with Linode.
- Access to Linode and its credentials set up appropriately.
- Helm repo for Airbyte added to your Helm configuration.

Replace placeholders like `us-central` and `0.1.0` with the appropriate values for your specific use case.

When you run this Pulumi program, it will perform an update which will show you a preview of the resources that Pulumi plans to create. Only after you confirm will Pulumi proceed to create the resources on Linode.

Keep in mind that this Pulumi program assumes that the `airbyte` helm repository is properly set up in your Helm configuration and that the repository contains a chart named `airbyte`. You may need to modify the `repo`, `chart`, and `version` values based on the actual Helm chart details for Airbyte.
