Deploy the frps helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the FRP (Fast Reverse Proxy) Server chart on Kubernetes using Pulumi, you will be using the `helm.sh/v3.Chart` resource from Pulumi's Kubernetes provider. This resource allows you to deploy Helm charts in a Kubernetes cluster. Pulumi works with Helm Charts by invoking the Helm CLI to render the charts, and then Pulumi takes that output and applies it to the cluster.

Here's a high-level overview of the steps involved:

1. Set up the Kubernetes provider in Pulumi to connect to your target Kubernetes cluster where you want to deploy the chart.
2. Define a `Chart` resource which refers to the FRPS Helm chart. You will need to provide the chart name, version (optional), and any custom values you want to apply.

Below is a Pulumi TypeScript program that demonstrates how to deploy the `frps` Helm chart on Kubernetes.

First, make sure you have the Pulumi CLI installed and that your Kubernetes cluster context is correctly set, because Pulumi will use the currently active Kubernetes context to deploy resources.

Now, let's dive into the code:

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

// Define the deployment of the FRPS Helm chart.
const frpsChart = new k8s.helm.v3.Chart('frps', {
  repo: 'your-helm-chart-repo', // Replace with the name of the Helm repository containing the FRPS chart.
  chart: 'frps', // The name of the chart in the repository.
  version: 'x.y.z', // Specify the version of the chart you want to deploy, if not latest.
  // Set custom values for the chart here. If you have a values file, you can pass its content as an object.
  values: {
    // Example of custom values. Replace these with actual configurable parameters of the FRPS chart.
    service: {
      type: 'LoadBalancer',
    },
    // Add other custom values as necessary
  },
  // If the chart is not in a public repository, you might need to specify fetch options to authenticate.
  fetchOpts: {
    // credentials for the repo if it is private
  },
});

// Export the public IP for the LoadBalancer, if applicable.
export const frpsServiceIP = frpsChart
  .getResourceProperty('v1/Service', 'frps', 'status')
  .apply(status => status.loadBalancer.ingress[0].ip);

```

In this program:

- We import the Pulumi Kubernetes SDK to interact with Kubernetes resources.
- We create a new Helm chart resource using `new k8s.helm.v3.Chart(...)`. You need to replace `'your-helm-chart-repo'` with the actual Helm repository where the FRPS chart is located. Similarly, replace `'x.y.z'` with the version of the chart you wish to deploy.
- We export the public IP address of the FRPS service assuming it's been set to `LoadBalancer` type, which would provide an external IP to access the service. Adjust this based on the actual service type and configuration.

Please note that you may need to adjust the specifics according to the actual FRPS chart you are deploying—this includes the repository name, chart version, and custom values like the service type or other configurable parameters of the FRPS chart. If the repository is private, you will need to supply the necessary authentication credentials via `fetchOpts`.

Before running this Pulumi program, make sure you're authenticated to your Kubernetes cluster and that the Helm chart repository containing the FRPS chart is correctly specified.

Once you have the program ready and have replaced the placeholders with actual values, you can run the following commands in your terminal:

```sh
pulumi up
```

This command will start the deployment process. Pulumi will show you a preview of the Kubernetes resources that will be created and will prompt you for confirmation before proceeding.
