Using kubernetes mindbody.com with spinnaker.io

Question

Pulumi · Accepted Answer

To automate deployments in a Kubernetes cluster using Spinnaker with Pulumi, you would typically do the following:

1. **Set up a Kubernetes cluster**: You can use Pulumi to define and manage Kubernetes clusters on any cloud provider.
2. **Install Spinnaker**: Spinnaker is a continuous delivery platform that can deploy to multiple clouds, including Kubernetes. While Pulumi does not directly manage Spinnaker installations, you can use Pulumi to set up the cloud resources that Spinnaker needs, such as VMs, network configurations, or managed Kubernetes services. Then, you can install Spinnaker manually or through an automation tool that you can invoke using Pulumi.
3. **Configure Spinnaker for Kubernetes deployments**: After Spinnaker is installed, you'd configure it to deploy to your Kubernetes clusters. This typically involves creating Spinnaker pipelines that reference Docker images to deploy, and possibly other deployment configurations such as canary or blue-green deployments.

In your scenario, you likely have a Kubernetes cluster running on Mindbody.com, and you want to set up Spinnaker to automate deployments to it. The following example will show you how to use Pulumi to create a simple Kubernetes cluster (using a hypothetical provider if Mindbody.com were supported). Then, we would describe the steps required to install and configure Spinnaker to work with the created cluster outside of Pulumi.

Please note, Pulumi does not provide specific support for either Mindbody.com or Spinnaker installation. If Mindbody.com supports Kubernetes, you can interact with it using the generic Kubernetes provider in Pulumi. Installing Spinnaker is typically done either manually or using a series of scripts or Helm charts, which you can also invoke using Pulumi.

Here's how you can create a Kubernetes cluster using Pulumi and TypeScript:

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

// Create a Kubernetes cluster using a generic provider.
// Replace the properties and the provider with the actual ones that are specific to Mindbody.com
const cluster = new kubernetes.core.v1.Namespace("my-cluster", {
    metadata: { name: "spinnaker-demo" },
});

// The cluster is now ready to be interacted with. At this point in real-world usage, you would use Pulumi to manage
// any required cloud resources or configurations needed for your Kubernetes cluster on Mindbody.com.
// Pulumi's work is done until it's time to update or manage cloud resources.

// The steps to install Spinnaker should be followed as per Spinnaker's documentation here:
// https://spinnaker.io/setup/install/
// It usually involves the Halyard tool to configure and deploy Spinnaker to your Kubernetes cluster.

// Once Spinnaker is installed using either the Halyard tool, Helm, or any other method, you must configure Spinnaker
// to connect to your Kubernetes cluster. This typically involves registering the Kubernetes cluster as a cloud provider in Spinnaker,
// and setting up deployment pipelines specific to your applications.

// After the cluster and Spinnaker are set up, you would use Spinnaker's UI or API to create and manage deployment pipelines.
```

Explanation:

1. The `@pulumi/kubernetes` package is used to work with Kubernetes resources.
2. We're creating a simple Kubernetes `Namespace` resource as a placeholder for where your cluster might be defined. In a real-world scenario, you'd have a more complex setup that includes nodes, a control plane, and other configuration, which might not be something directly managed by Pulumi if your Kubernetes service is provided by Mindbody.com.

Post-Pulumi steps:

1. **Install Spinnaker**: Follow the [official Spinnaker installation guide](https://spinnaker.io/setup/install/) to install Spinnaker in your Kubernetes cluster.
2. **Configure Kubernetes provider in Spinnaker**: You'll need to let Spinnaker know about your Kubernetes cluster, typically by using the `kubectl` tool to apply configurations or by setting up the required permissions and service accounts. Spinnaker's documentation provides a comprehensive guide on this.
3. **Set up deployment pipelines**: Use Spinnaker's UI to create and manage deployment pipelines, which will automate the deployment of your applications to the Kubernetes cluster.

Please note that the details of Spinnaker's installation and configuration can be extensive and are beyond the Pulumi context. You would need to refer to the Spinnaker documentation or enlist the help of a Spinnaker expert for this part. The Pulumi code here merely sets up the Kubernetes resources which Spinnaker will then use.
