Deploy the tyk-dev-portal helm chart on Kubernetes

Question

Pulumi · Accepted Answer

When deploying a Helm chart with Pulumi, we can define a `Chart` resource from the `@pulumi/kubernetes` package. This resource allows for Helm charts to be deployed to a Kubernetes cluster. You will need to provide the name of the chart, the repository where the chart is hosted, and any necessary configuration values required by the chart.

In the following program, we'll use the `kubernetes.helm.v3.Chart` class to deploy the Tyk Developer Portal on Kubernetes. This assumes you have a Kubernetes cluster already running and configured with `kubectl`.

First, make sure you have the Pulumi CLI installed and the Kubernetes configuration pointing to your cluster. You'll also need to install Node.js and npm to run the Pulumi program.

Here's a Pulumi TypeScript program to deploy the Tyk Developer Portal Helm chart:

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

const tykDevPortalChart = new k8s.helm.v3.Chart("tyk-dev-portal", {
    repo: "tyk-helm", // The repository name where the chart is located
    chart: "tyk-dev-portal", // The chart name to deploy
    // Add necessary values here. You might need to consult the chart's documentation
    // for the specific values it requires.
    values: {
        // Values might include specific configurations like domain, replicaCount, etc.
    },
}, { provider: k8sProvider }); // Assuming you have a Kubernetes provider instance named `k8sProvider`

export const chartName = tykDevPortalChart.metadata.name; // Exports the name of the chart
```

Before deploying, you might need to add or update the Tyk Helm chart repository to your Helm CLI:

```
helm repo add tyk-helm https://helm.tyk.io/public/helm/charts/
helm repo update
```

In the `values` object, you should specify configuration options that are required by the chart. These options can be found in the `values.yaml` file of the Helm chart or in the chart's documentation. The configurations can include resource limitations, service types, persistence options, among others.

It's important to check the official documentation of the chart for any prerequisites or setup that needs to be done prior to installing the chart. For example, setting up a required database, or providing credentials and other configurations via the `values` specified in the chart deployment.

Finally, to deploy this chart to your Kubernetes cluster, run `pulumi up` in the same directory as your code.

This code export the chart's name, which you could use later on to query the deployed chart's status or if you want to reference it in other parts of your Pulumi program. If you would like to expose other information such as service URLs or persistent volume claims, you can include them in the export section as well.
