Deploy the laravel-octane helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy a Laravel Octane application using the Helm chart on Kubernetes, you'll utilize the Pulumi `kubernetes.helm.v3.Chart` resource, which allows you to deploy Helm charts into a Kubernetes cluster. The `Chart` resource is a high-level abstraction that simplifies the deployment of applications defined by Helm charts.

First, you need to have a Kubernetes cluster up and running. Pulumi can work with any existing Kubernetes cluster, or you can use Pulumi to provision a new one. In this example, we'll assume that you have a Kubernetes cluster and that your `kubeconfig` file is correctly configured to connect to it.

Below is a Pulumi program in TypeScript that demonstrates how to deploy a Laravel Octane application using a Helm chart. This program creates a new instance of `Chart` and specifies the necessary details such as the repository from where the chart will be fetched, the name of the chart, and the desired namespace.

Please note that I am assuming the existence of a Helm chart for Laravel Octane that is hosted in a public or private Helm repository. You'll need to replace `CHART_REPO_URL` with the actual URL of the Helm chart repository and `laravel-octane` with the correct chart name if it differs.

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

// Deploy a Laravel Octane Helm chart into the 'default' namespace.
const laravelOctaneChart = new k8s.helm.v3.Chart("laravel-octane", {
    repo: "CHART_REPO_URL", // Replace with your Helm chart's repository URL.
    chart: "laravel-octane", // Replace with your actual Helm chart's name if different.
    namespace: "default",
    // Specify the values for the Laravel Octane chart.
    // For example, you can override default values like image tags, resource limits, or any custom Laravel Octane values.
    values: {
        // Replace these values with the ones relevant to the Laravel Octane chart.
        // image: { tag: "latest" }, 
        // resources: { limits: { cpu: "100m", memory: "128Mi" }, requests: { cpu: "100m", memory: "128Mi" } },
    },
}, { provider: k8sProvider }); // The Kubernetes provider is used to apply the chart to the cluster.

export const laravelOctaneChartStatus = laravelOctaneChart.status;
```

This program can be part of a larger Pulumi project. When you run it using the Pulumi CLI, it will execute the deployment in the context of the current Kubernetes context set in your `kubeconfig`. If you need to specify a different context, you can add a `k8s.Provider` instance with the specific context.

In the `values` object, you can specify the necessary configuration for your Laravel Octane application. These may include things such as container image tags, environment variables, resource limits for the pods, persistence configurations, etc. Please refer to the Helm chart's documentation for all available options.

The output variable `laravelOctaneChartStatus` exports the status of the deployed chart, which you can use to track the deployment's progress and status.

Remember to run `npm install @pulumi/pulumi @pulumi/kubernetes` to install the necessary Pulumi packages before running this program.

Let's say you have the content above saved in a file called `index.ts`. You can then run `pulumi up` to start the deployment process. The `pulumi up` command will show you a preview of the resources that will be created and ask for your confirmation before proceeding to modify the state of your cloud resources.
