1. Deploy the parca helm chart on Digital Ocean Kubernetes Service


    To deploy the Parca Helm chart on the Digital Ocean Kubernetes Service (DOKS), we will perform the following steps programmatically using Pulumi with TypeScript:

    1. Set up the necessary imports and create an instance of a DigitalOcean Kubernetes cluster.
    2. Install the Parca Helm chart onto the Kubernetes cluster.

    Here's a detailed breakdown of the Pulumi program:

    1. DigitalOcean Kubernetes cluster: We instantiate a Kubernetes cluster where our Parca instance will run. This will allocate the necessary resources in DigitalOcean.

    2. Helm chart for Parca: We define a Helm chart resource which points to the Parca chart. Using the Kubernetes provider configured with our cluster connection details, Pulumi can install Helm charts directly onto our Kubernetes cluster.

    For this example, you need to have Pulumi installed, and you should be logged in to both Pulumi and the DigitalOcean API (with proper credentials set up). Make sure you have Helm chart details like its repository URL and the chart version if you require a specific one.

    Now, let's assemble the Pulumi program:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Create a DigitalOcean Kubernetes cluster (DOKS). const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", version: "latest", // Or specify the exact DigitalOcean Kubernetes version. nodePool: { name: "default-pool", size: "s-1vcpu-2gb", nodeCount: 1, }, }); // Obtain a KubeConfig file from the DigitalOcean cluster. const kubeConfig = pulumi .all([cluster.id, cluster.endpoint, cluster.kubeConfigs]) .apply(([id, endpoint, kubeConfigs]) => { if (kubeConfigs && kubeConfigs[0]) { return kubeConfigs[0].rawConfig; } throw new Error("KubeConfig not available"); }); // Create a Kubernetes provider instance using the KubeConfig from DigitalOcean cluster. const k8sProvider = new kubernetes.Provider("do-k8sProvider", { kubeconfig: kubeConfig, }); // Define the Parca Helm chart resource, using the Helm provider. const parcaChart = new kubernetes.helm.v3.Chart("parca", { chart: "parca", version: "0.1.0", // Replace with the desired version of Parca Helm chart. fetchOpts: { repo: "https://parca.dev/helm-charts/" }, }, { provider: k8sProvider }); // Exports export const kubeConfigOutput = kubeConfig; // You can output the kubeconfig file to connect to your Kubernetes cluster. export const parcaEndpoint = cluster.endpoint; // You can use this endpoint with `kubectl` to access your Parca instance.


    This program sets up a Kubernetes cluster on DigitalOcean and deploys the Parca Helm chart to it:

    • It starts by importing the necessary Pulumi packages for working with DigitalOcean and Kubernetes (@pulumi/digitalocean and @pulumi/kubernetes).

    • We create a new DigitalOcean Kubernetes cluster with the desired region, version, and node pool configuration.

    • The kubeConfig variable takes the kubeconfig file from the created DigitalOcean Kubernetes cluster, which will be used to communicate with the cluster.

    • The k8sProvider variable creates a Kubernetes provider with the obtained kubeconfig.

    • The parcaChart variable deploys the Parca Helm chart into our cluster using the created Kubernetes provider.

    • Finally, we export the kubeconfig and the Kubernetes cluster endpoint as stack outputs. These can be used to interact with and access the deployed Parca instance using tools like kubectl.

    After deploying with Pulumi (pulumi up), you can use the exported kubeConfigOutput to configure kubectl and the parcaEndpoint to access the Parca UI or API.
