Deploy the pyroscope-mixin helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the pyroscope-mixin Helm chart on Linode Kubernetes Engine (LKE), you'll want to use Pulumi's support for Kubernetes resources. We will focus on deploying a Helm chart on an existing Kubernetes cluster. Below is the TypeScript program that demonstrates how to achieve this with Pulumi.

First, ensure you have a Kubernetes context configured for the Linode Kubernetes Engine (this is typically done using the linode-cli or by downloading the Kubeconfig from the Linode Cloud Manager). Pulumi uses this context from your kubeconfig file to communicate with your Kubernetes cluster.

Here's what the program does, step by step:

It imports the necessary Pulumi and Kubernetes packages.
Sets up a Helm chart resource for pyroscope-mixin using the Chart class from the Kubernetes package.

Make sure to install the necessary Pulumi libraries using npm or yarn before executing the program:

npm install @pulumi/pulumi @pulumi/kubernetes

Below is the TypeScript code:

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

// Create an instance of the Helm chart for pyroscope-mixin.
// You may need to specify the repository where the Helm chart is located
// and the version of the chart you want to deploy.
const pyroscopeMixinChart = new k8s.helm.v3.Chart('pyroscope-mixin', {
    chart: 'pyroscope-mixin', // Replace with the correct chart name if different.
    version: 'x.y.z', // Specify the chart version; replace x.y.z with actual version number.
    fetchOpts: {
        repo: 'https://pyroscope-helm-repository-url/', // Replace with actual Helm repository URL.
    },
    // The values below are placeholders. You would need to provide configuration
    // according to the pyroscope-mixin Helm chart's requirements.
    // These typically reflect the Pyroscope configuration.
    values: {
        service: {
            type: 'ClusterIP',
            port: 4040,
        },
        // other configuration values...
    },
}, { provider: new k8s.Provider("pyroscope-provider", { kubeconfig: "<KUBECONFIG_CONTENTS>" }) });

// Export the service name and endpoint of the pyroscope-mixin deployment.
export const serviceName = pyroscopeMixinChart.getResourceProperty("v1/Service", "pyroscope-mixin", "metadata", "name");
export const serviceEndpoint = pyroscopeMixinChart.getResourceProperty("v1/Service", "pyroscope-mixin", "status", "loadBalancer", "ingress", "0", "hostname");

In the code above:

Replace https://pyroscope-helm-repository-url/ with the actual repository URL for the pyroscope-mixin Helm chart.
Specify the correct chart version in place of x.y.z.
Customize the values according to your needs. The values should correspond to the settings recommended by pyroscope-mixin for your context. You can find these in the chart's values.yaml or the documentation provided with the chart.
<KUBECONFIG_CONTENTS> should be replaced with the actual contents of your kubeconfig file to allow Pulumi to communicate with your Linode Kubernetes cluster. Usually, this isn't hardcoded; instead, you use the default kubeconfig context or manage your configuration outside the program for security reasons.

After writing this program, you can run it with Pulumi's CLI tools to deploy the Helm chart to your Linode Kubernetes cluster. When executed, Pulumi will provision the Helm chart which in turn will create resources in your LKE cluster according to the Pyroscope configuration you've specified.
