1. Deploy the prometheus-beanstalkd-exporter helm chart on Rancher


    To deploy the prometheus-beanstalkd-exporter Helm chart on a Rancher-managed Kubernetes cluster, you need to perform a series of steps:

    1. Set up a Rancher Kubernetes cluster or have access to an existing one.
    2. Configure Pulumi to interact with the Rancher API.
    3. Use the Pulumi Rancher2 provider to deploy the Helm chart.

    The following is a step-by-step guide with a complete Pulumi program in TypeScript that demonstrates how to deploy the Helm chart. I'll explain each section of the program and the resources that Pulumi will create or interact with.

    First, we need to install the necessary Pulumi packages for interacting with Kubernetes and Rancher. You can do this by running the following commands:

    npm install @pulumi/rancher2 npm install @pulumi/kubernetes

    After installing the packages, create a new TypeScript file (e.g., index.ts) and follow the program below. Each section is commented to explain what it does.

    Program to Deploy prometheus-beanstalkd-exporter Helm Chart on Rancher

    import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; // This is the Rancher Kubernetes cluster where you want to deploy the Helm chart. // You should have the cluster already configured in Rancher and have the cluster's access credentials. const cluster = new rancher2.Cluster("my-cluster", { /* ... */ }); // Please insert the appropriate configuration for your cluster in place of `{ /* ... */ }`. // For example, you might need to specify the Rancher URL, access key, secret key, and the cluster ID. // After setting up the cluster, create a Kubernetes provider instance that specifically targets your Rancher Kubernetes cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfig, }); // This section installs the `prometheus-beanstalkd-exporter` Helm chart into your Rancher Kubernetes cluster. // Replace `<CHART-VERSION>` with the specific chart version you want to deploy. // You can also adjust the `values` with the appropriate configuration options for the `prometheus-beanstalkd-exporter`. const beanstalkdHelmChart = new k8s.helm.v3.Chart("prometheus-beanstalkd-exporter", { chart: "prometheus-beanstalkd-exporter", version: "<CHART-VERSION>", // Replace with the specific version of the Helm chart. fetchOpts:{ repo: "https://helm-charts/prometheus-community", // Replace with the correct Helm chart repository URL. }, values: { // Specify any values that you want to override from the default Helm chart values here. // For instance, you might want to set the address and port for your beanstalkd service: beanstalkd: { address: "beanstalkd-service", // Replace with the address of your beanstalkd service. port: 11300, // Replace with the port number that your beanstalkd service listens on. }, }, }, { provider: k8sProvider }); // If you need to expose any services or perform additional configuration, // you can continue to define Kubernetes resources here using the `k8s` provider. // To access your deployment or get details about the running services, you might want to export certain properties. // For example, you might want to export the status of the Helm release: export const helmReleaseStatus = beanstalkdHelmChart.status; // Using this information, you can check if the deployment is successful and verify that your Prometheus exporter is running.

    In the program above, we define a Rancher Kubernetes cluster resource, then create a Pulumi Kubernetes provider that is configured to connect to that cluster using its kubeConfig. We proceed with deploying the prometheus-beanstalkd-exporter Helm chart.

    The new k8s.helm.v3.Chart resource represents a Helm chart that Pulumi will deploy to your Kubernetes cluster. The version property specifies the version of the Helm chart you want to deploy, while fetchOpts.repo contains the URL to the Helm chart repository.

    We also use the values object to override default Helm chart values with custom settings specific to your deployment. In this example, we hypothetically override the beanstalkd.address and beanstalkd.port values to point to the actual service deployed in your cluster.

    Lastly, we export the status of the Helm release so that you can check if the deployment was successful. To run the Pulumi program, you would typically use the Pulumi CLI commands like pulumi up to preview and apply changes.

    Remember to fill in the placeholders (e.g., <CHART-VERSION> and repository URLs) with the actual values for your use case. Additionally, adjust the configuration options in the values object according to the prometheus-beanstalkd-exporter Helm chart's documentation and your specific requirements.
