Deploy the akash-faucet helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `akash-faucet` Helm chart on an OpenShift cluster using Pulumi, you'll need to perform several steps. First, ensure you have the OpenShift cluster up and running and Pulumi set up properly with the required provider. We'll then define a Pulumi program to deploy the Helm chart to your OpenShift cluster.

1. **Cluster Configuration**: Before deploying the Helm chart, ensure that you have access to the OpenShift cluster and the `oc` command-line tool is configured to communicate with your cluster. Your `kubeconfig` file should be correctly set up to manage the cluster's resources.

2. **Pulumi Setup**: Make sure that you have Pulumi installed and configured for TypeScript. Create a new Pulumi project using `pulumi new typescript`.

3. **Kubernetes Provider for OpenShift**: Since OpenShift is a Kubernetes distribution, we will use the Pulumi Kubernetes provider to interact with your cluster. The provider needs to be configured with the appropriate `kubeconfig` file or other authentication mechanisms to access your OpenShift cluster.

4. **Deploying the Helm Chart**: The Pulumi Kubernetes provider includes a `Chart` resource that allows us to deploy Helm charts. We will define a Pulumi stack with a `Chart` resource for the `akash-faucet` Helm chart.

Here's a Pulumi TypeScript program that demonstrates how to deploy the `akash-faucet` Helm chart on OpenShift. Please note that you should replace `{REPOSITORY_URL}` with the URL to the Helm repository that hosts the `akash-faucet` chart if it's not available in the default Helm repositories.

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

// Replace with the actual repository URL that hosts akash-faucet
const repositoryUrl = "{REPOSITORY_URL}";

// Define the akash-faucet Helm chart resource
const akashFaucetChart = new k8s.helm.v3.Chart("akash-faucet", {
    repo: "akash", // The repository name, change if different
    chart: "akash-faucet",
    version: "0.1.0", // Specify the version of the chart you want to deploy
    fetchOpts: {
        repo: repositoryUrl, // URL to the repository where the chart is located
    }
    // You can provide additional configurations such as `values` for custom values.yaml content
});

// Export the endpoints of the akash-faucet service
export const akashFaucetService = akashFaucetChart.getResource("v1/Service", "akash-faucet");

```

### Explanation:

- We import the `@pulumi/kubernetes` module, which contains the necessary functions to interact with Kubernetes clusters.

- We define a Helm chart resource using the `Chart` resource type provided by the Pulumi Kubernetes provider. This resource represents a Helm chart that Pulumi can manage. It requires the name of the chart, the repository where it is stored, and the version of the chart.

- The `repo` property specifies the name of the repository that holds the `akash-faucet` chart. Change it according to where the chart is actually hosted.

- The `chart` property specifies the name of the chart we want to deploy, which is `akash-faucet`.

- The `version` property is optional and useful if you need to pin the chart to a specific version.

- The `fetchOpts` section contains a `repo`, which is the URL to the Helm repository that hosts the `akash-faucet` Helm chart.

- In the `export` statement, we extract the `Service` resource created as part of the Helm chart deployment. This can be used to retrieve the endpoint of the service after the deployment if needed.

After defining your Pulumi program, you can run it using the following commands in your terminal:

```shell
pulumi up
```

This will prompt you to confirm the deployment after displaying a preview. Once confirmed, Pulumi will proceed with deploying the Helm chart to your OpenShift cluster. After successful deployment, Pulumi will output any exported endpoints.

Remember to replace `{REPOSITORY_URL}` with the actual URL of the Helm repository that contains the `akash-faucet` chart. If this URL or other configuration like `values` is unknown, you'll need to obtain this information from the chart's maintainers or the documentation that comes with the chart.
