1. Deploy the vechr-monitoring helm chart on Rancher


    To deploy a Helm chart on Rancher using Pulumi, you'd need to interact with your Kubernetes cluster through Rancher's API. Pulumi provides resources through the rancher2 package to manage Rancher resources, although as of my knowledge cutoff in early 2023, there isn't a direct Pulumi resource for deploying a Helm chart on Rancher.

    However, you can create and manage Kubernetes resources like namespaces, deployments, and services with Pulumi's Kubernetes provider, and to some extent, manage Helm releases with Pulumi's Helm provider. Deploying a specific Helm chart like vechr-monitoring would typically involve the following steps:

    1. Importing the necessary Pulumi packages.
    2. Configuring access to the Kubernetes cluster through Rancher.
    3. Deploying the Helm chart using the Pulumi Kubernetes provider.

    Here's a sample Pulumi program that demonstrates how you would use Pulumi to deploy a Helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Configuration for the Rancher cluster const rancherConfig = new pulumi.Config("rancher"); const clusterId = rancherConfig.require("clusterId"); const clientToken = rancherConfig.requireSecret("clientToken"); // Create a provider for the Kubernetes cluster managed by Rancher const clusterProvider = new rancher2.Provider("my-rancher", { api_url: "https://<RANCHER-HOST>/v3", tokenKey: clientToken, clusterId: clusterId, }); // Deploy a Helm chart using the Pulumi Kubernetes provider const chart = new k8s.helm.v3.Chart("vechr-monitoring-chart", { chart: "vechr-monitoring", version: "1.0.0", // Specify the chart version you want to deploy fetchOpts: { repo: "https://charts.example.com/", // Replace with the Helm chart's repository URL }, }, { provider: clusterProvider }); // Export the Helm chart's status export const helmStatus = chart.status;

    In the above program:

    • We import the necessary modules from Pulumi's libraries for Kubernetes (@pulumi/kubernetes) and Rancher (@pulumi/rancher2).
    • We set up configuration variables to store the Rancher cluster ID and a client token for authentication. These would typically come from Pulumi's configuration system or environment variables for security reasons.
    • We create a Rancher provider instance using the API URL of your Rancher server, and we authenticate using the clientToken.
    • We define a new Helm chart resource using Pulumi's Kubernetes provider, specifying the name of the chart (vechr-monitoring), the chart version, and the repository containing the Helm chart. We pass the clusterProvider created earlier so that the Helm chart is deployed to the Kubernetes cluster managed by Rancher.

    Before running this Pulumi program, you would need to:

    1. Replace <RANCHER-HOST> with the actual URL of your Rancher host.
    2. Replace https://charts.example.com/ with the actual URL of the Helm chart repository that contains the vechr-monitoring chart.
    3. Ensure that you have the necessary permissions and client token to access the Rancher API and the Kubernetes cluster managed by Rancher.
    4. Install the Pulumi CLI and set up your Pulumi stack.

    Once your program is written and Pulumi and Kubernetes are configured correctly, you can deploy your stack with the Pulumi CLI using the following commands:

    pulumi up

    This command will show you a preview of the resources that will be created/updated/destroyed and, upon your confirmation, apply these changes to your cloud infrastructure.

    Keep in mind that this code assumes that the Helm chart named vechr-monitoring exists in the given repository. You'll need to adjust this if the chart or repository is named differently.
