Using kubernetes yaml with minio.min.io

Question

Pulumi · Accepted Answer

When you want to deploy a MinIO object storage instance on a Kubernetes cluster using YAML files with Pulumi, there are a few steps you'll need to follow. Pulumi provides first-class support for Kubernetes resources, including the ability to deploy resources defined in YAML.

The resources you'll use in this scenario include `ConfigFile` and `ConfigGroup` from the `@pulumi/kubernetes` package to deploy resources from YAML files.

Here’s a breakdown of the steps you’ll take in your Pulumi program:

1. **Import necessary packages**: You'll need the Pulumi SDK and the Kubernetes package.
2. **Create a Kubernetes ConfigFile or ConfigGroup**: These resources are used to deploy YAML manifest files. `ConfigFile` is used for a single file, while `ConfigGroup` is used for multiple files or to specify content directly in TypeScript.
3. **Deploy MinIO**: You'll use a YAML file for MinIO that defines the necessary Deployment, Service, and other resources. (Assuming you have a file called `minio.yaml` that contains the correct resource specifications.)

For this explanation, we'll use the `ConfigFile` resource for deploying a single YAML file. If you're deploying multiple files or want to specify YAML content inline, you would use `ConfigGroup`.

Below is your Pulumi TypeScript program that handles this deployment:

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

// Create a Kubernetes ConfigFile resource to deploy MinIO using a YAML manifest.
// You should have a minio.yaml file that includes MinIO deployment configurations.
const minio = new k8s.yaml.ConfigFile("minio", {
  file: "path/to/your/minio.yaml", // Replace with the actual path to your MinIO YAML file.
});

// Export the MinIO service endpoint to access MinIO once it's deployed.
export const minioEndpoint = minio.getResourceProperty("v1/Service", "minio-service", "status").apply(status => {
  return status.loadBalancer.ingress[0].ip; // This depends on your Service type and configuration.
});
```

In this code:

- We import the `@pulumi/kubernetes` package which contains helpers for interacting with Kubernetes resources.
- We create an instance of `ConfigFile` named `minio`. This resource represents the YAML manifest file for MinIO which should be located at the specified path.
- Lastly, we define an export for the MinIO service endpoint which allows us to interact with the MinIO instance after it has been deployed. Note that accessing the service's IP or hostname would depend on how you've configured the MinIO service in your YAML file, and the specific cloud provider's implementation of LoadBalancer services.

To complete this process, you should have:

- A Kubernetes cluster where you have appropriate permissions to deploy applications.
- The Pulumi CLI installed and configured with the necessary credentials to communicate with your Kubernetes cluster.
- A YAML file with the configuration to deploy MinIO (typically found in the MinIO documentation or created based on your specific storage requirements).

After deploying this program with Pulumi, MinIO will be up and running in your cluster, provisioned according to the specifications in the `minio.yaml` file. You can then interact with your MinIO instance through the endpoint provided by the exported variable.
