1. Deploy the parca helm chart on Kubernetes


    To deploy the Parca Helm chart on a Kubernetes cluster using Pulumi, you need to have the Pulumi CLI installed and configured on your machine, along with kubectl configured for accessing your Kubernetes cluster.

    We will write a Pulumi program in TypeScript that will deploy the Parca Helm chart to your Kubernetes cluster. The @pulumi/kubernetes package will be our main dependency, which allows Pulumi to interact with Kubernetes resources. Specifically, we'll use the Chart resource from the Helm package within the Kubernetes provider to deploy the chart.

    Here is how the program will work:

    1. Setup: Import necessary Pulumi libraries.
    2. Chart Deployment: Define a Chart resource to deploy Helm chart of Parca. It is worth mentioning that the chart might require specific values which are usually defined in a values.yaml file for Helm deployments. You can pass these values using the values parameter within Pulumi’s Chart resource.

    Below is the detailed Pulumi TypeScript program:

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Initialize a new k8s Provider instance using the current context from kubeconfig. // Assuming `kubeconfig` is properly set in your environment. // Otherwise, you may need to explicitly pass the kubeconfig file to the k8s.Provider constructor const provider = new k8s.Provider('k8s-provider', { // If you need to specify a different context or a specific kubeconfig file, // you can uncomment the following lines and provide the necessary values: // kubeconfig: '<path-to-your-kubeconfig-file>', // context: '<your-kubernetes-context>', }); // Step 2: Deploy the Parca Helm chart using the `k8s.helm.v3.Chart` resource. // Replace `<namespace>` with the namespace you want to deploy Parca into. // You may have a `values` object with the required configuration based on the Parca Helm chart's // requirements or use the default ones provided by the chart. const parcaChart = new k8s.helm.v3.Chart('parca-chart', { chart: 'parca', version: '<chart-version>', namespace: '<namespace>', fetchOpts: { repo: 'https://parca.dev', // The Helm repository URL, replace if different. }, // If you need to provide custom values, uncomment the following and // add necessary key-value pairs. // values: { // key: 'value', // // ... add more values as needed // }, }, { provider }); // Optional: You can export the status URL of Parca if it exposes any services. // This only works if Parca chart service type is LoadBalancer or NodePort and has ingress resources. export const parcaUrl = parcaChart.getResourceProperty('v1/Service', 'parca', 'status').apply(status => { // The `status` value here will depend on how Parca service is set up. // Adjust the logic to construct the URL accordingly. The example here assumes a LoadBalancer type. if (status.loadBalancer.ingress && status.loadBalancer.ingress[0]) { const ingress = status.loadBalancer.ingress[0]; return ingress.ip || ingress.hostname; // Depending on what the LoadBalancer provides. } return 'Service does not have an external IP yet. Check again later.'; });


    • The k8s.Provider class is utilized to define which Kubernetes cluster the Helm chart should be deployed to. It uses your current context from the kubeconfig file.
    • The k8s.helm.v3.Chart class represents the Helm chart that you want to install. In this case, we are deploying the "parca" chart. You can specify the chart version and namespace where the chart should be installed.
    • fetchOpts are options passed to Helm on how to fetch the chart, including the repository URL.
    • values is where you put configuration options that overwrite the defaults set in the Helm chart (which would usually be done via overriding a values.yaml file). This is commented out in the above example, but you can customize it based on your needs.
    • An optional export statement is included to expose the Parca service URL after deployment. This assumes the service type is LoadBalancer, which will allocate an external IP or URL. If using a different service type, you'd need to adjust the logic accordingly.

    Remember to replace placeholder <chart-version> with the actual version of Parca Helm chart you want to deploy and <namespace> with the target namespace. Ensure that you have the correct Helm repository URL to fetch the Parca chart or change it if it's hosted at a different location.

    This program gives you the foundation to deploy a Helm chart and can be extended further based on the complexity and requirements of your deployment.
