Deploy the tyk-dev-portal helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `tyk-dev-portal` Helm chart on an OpenShift cluster using Pulumi, you'll need to have access to the cluster and be able to interact with it using `kubectl`. The following Pulumi program assumes that you have the necessary access and that your Pulumi environment is already configured for the Kubernetes provider.

We will use the `kubernetes.helm.v3.Chart` resource from Pulumi's Kubernetes provider to deploy the Helm chart. The `Chart` resource allows us to specify the details of the Helm chart we wish to deploy, such as repository, chart name, values, version, etc.

Here is a program written in TypeScript that demonstrates how to deploy the `tyk-dev-portal` Helm chart on an OpenShift cluster:

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

// Create a new Helm chart instance for the tyk-dev-portal
const tykDevPortalChart = new k8s.helm.v3.Chart("tyk-dev-portal", {
    // Replace with the correct repository URL for the tyk-dev-portal Helm chart
    repo: "the-repository-url",
    chart: "tyk-dev-portal",
    // Specify the namespace where the chart should be deployed
    // It should be an existing namespace or you can create one exlicitly as part of this program.
    namespace: "tyk-dev-portal-namespace",
    // Override default configuration values here.
    // This is where you can set values as you would do in a typical values.yaml file
    // or with the `--set` command line argument when using helm directly.
    values: {
        // Add configuration values specific to tyk-dev-portal here
    },
    // Optionally, you can specify the version of the chart to be deployed
    version: "chart-version",
}, { provider: /* a k8s Provider resource if required, such as when using more than one cluster */ });

export const chartName = tykDevPortalChart.metadata.name;
```

This Pulumi program will declare a Helm chart and attempt to deploy it. To explain what we're doing:

- We import the `@pulumi/kubernetes` package to interact with Kubernetes resources.
- We create a Helm chart resource called `tykDevPortalChart`, which represents the Tyk Developer Portal Helm chart we want to deploy.
- In the `Chart` constructor, we provide an object with configuration options:
  - `repo` should be replaced with the actual URL of the repository where the Tyk Helm chart is hosted.
  - `chart` specifies the name of the chart we want to deploy; in this case, `tyk-dev-portal`.
  - `namespace` is where our chart will be deployed within the Kubernetes cluster. Ensure that the namespace exists; otherwise, you can manage namespace resources in Pulumi too.
  - `values` are the settings for the chart, comparable to what you might place in a `values.yaml` file or pass via the `--set` Helm CLI option. You will need to provide the actual values that apply to your deployment here.
  - `version` is used to specify the version of the Helm chart you want to deploy. If this option is omitted, the latest version is installed.
- The `provider` option is available if you need to target a specific Kubernetes cluster, especially when dealing with multiple clusters. You may omit this if you have a single cluster setup with default credentials in your environment.
- The export statement at the end makes the name of the deployed chart accessible as an output once Pulumi has completed deploying your resources to the cluster.

Before running this program, ensure you have done the following:
- Installed Pulumi and configured it for use with your Kubernetes cluster.
- Authenticated with your OpenShift cluster so that Helm and Pulumi can communicate with it.
- Replaced the placeholder values (`the-repository-url`, `tyk-dev-portal-namespace`, `chart-version`, etc.) with actual values that match your specific deployment requirements.

To run this program, save it to a file (e.g., `index.ts`), and use the Pulumi command-line interface:

```sh
pulumi up
```

Pulumi will then perform the deployment, and you'll be able to see the status and any errors in your terminal. When the deployment succeeds, you will find the Tyk Developer Portal running in your OpenShift cluster in the specified namespace.
