1. Deploy the thanos-config helm chart on Rancher


    To deploy a Helm chart on Rancher using Pulumi, you'll need to interact with the Kubernetes API provided by Rancher. This involves a sequence of steps:

    1. Setting up Rancher with a Kubernetes cluster.
    2. Installing the Helm chart onto the cluster through Rancher's application deployment mechanisms.

    Rancher streamlines Kubernetes deployment and management. Pulumi can use Rancher's capabilities by interacting with it as a Kubernetes provider.

    For deploying a Helm chart like thanos-config we'd typically use Pulumi's support for Helm charts. It looks like we don't have a direct Pulumi example deploying a Helm chart specifically in Rancher, but I'll guide you through a generic Helm chart deployment in a Kubernetes cluster managed by Rancher in TypeScript.

    Here’s a step-by-step guide with a Pulumi program:

    Set Up Rancher and Kubernetes Cluster

    Before deploying the Helm chart, you need to have a Kubernetes cluster managed by Rancher. You could use Pulumi's rancher2 provider to set up the cluster by defining a rancher2.Cluster resource, or you can use a cluster already created and managed via the Rancher UI or another method.

    For sake of explanation, we'll assume that you already have a Kubernetes cluster set up in Rancher and have the kubeconfig file for accessing the cluster.

    Install Pulumi and Configure Rancher Kubernetes Provider

    Make sure you have Pulumi installed and configured with the necessary cloud credentials. Since we are using Rancher, ensure you have the kubeconfig file location ready to inform Pulumi where to deploy the Helm chart.

    Pulumi Program to Deploy thanos-config Helm Chart

    The following is a Pulumi program in TypeScript:

    import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; // Load the configuration for the Rancher-managed Kubernetes cluster // Typically this could be loaded from a file on disk or passed through configuration const kubeconfig = pulumi.output("<YOUR_RANCHER_KUBECONFIG_CONTENTS>"); // Create a Kubernetes provider instance using the kubeconfig obtained from Rancher const rancherK8sProvider = new k8s.Provider("rancher-k8s", { kubeconfig: kubeconfig, }); // Define the Helm chart resource for the Thanos configuration const thanosChart = new k8s.helm.v3.Chart("thanos-config", { chart: "thanos", // This version should match the version of the Helm chart you want to deploy version: "<CHART_VERSION>", // Specify any values you would like to override, similar to using the `--set` flag with Helm CLI values: { // Define specific values dependent on the Thanos Helm chart's values schema // These are placeholder values service: { type: "ClusterIP", }, }, }, { provider: rancherK8sProvider }); // Export the status of the Helm chart deployment export const thanosStatus = thanosChart.status;

    Please replace <YOUR_RANCHER_KUBECONFIG_CONTENTS> with the actual content of the kubeconfig file you have for the cluster managed by Rancher. Similarly, replace <CHART_VERSION> with the specific version of the Thanos chart you want to deploy.

    In the above code, we:

    • Import the necessary Pulumi packages for Kubernetes and Rancher.
    • Use the @pulumi/kubernetes package to interact with the Kubernetes API and manage the Helm chart.
    • Specify the Helm chart we want to deploy (thanos-config), defining any overrides we need in the values property.
    • Export the status of the Helm release so that you can see whether the deployment was successful after running pulumi up.

    This is a high-level explanation, and the actual details may vary based on the exact thanos-config Helm chart you're deploying, your Rancher setup, and necessary configuration.

    Remember to replace placeholders with actual values that correspond to your setup and Helm chart. You might need specific Helm chart settings or Rancher cluster configuration that are not covered by this generic example.
