1. Deploy the mysql-exporter helm chart on Rancher

    TypeScript

    To deploy the mysql-exporter Helm chart on Rancher using Pulumi, you'll need to perform the following steps:

    1. Set up the Pulumi project and stack.
    2. Install the dependencies, such as Pulumi Rancher2 and Helm providers.
    3. Configure the Rancher2 provider to communicate with your Rancher instance.
    4. Retrieve the cluster where you wish to deploy the Helm chart.
    5. Use the Helm provider to deploy the mysql-exporter chart onto the cluster managed by Rancher.

    Below is an example of a Pulumi program written in TypeScript that demonstrates how to deploy the mysql-exporter Helm chart on Rancher:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Initialize the Pulumi project and stack by creating a new project and stack // Step 2: Configuring the Rancher2 provider const rancher2Provider = new rancher2.Provider("rancherProvider", { // Provide the necessary credentials and endpoint to connect to your Rancher server apiToken: "your-rancher-api-token", apiUrl: "https://your-rancher-instance/v3", }); // Step 3: Retrieving a cluster in Rancher const cluster = rancher2.getCluster({ name: "your-cluster-name", }, { provider: rancher2Provider }); // Step 4: Deploying the `mysql-exporter` Helm chart using the Helm provider // Assume that you have configured a KubernetesProvider here using the kubeconfig // for the cluster retrieved in the previous step const helmProvider = new k8s.Provider("helmProvider", { kubeconfig: cluster.kubeConfig, // Use the kubeconfig from the obtained cluster }); // Use the cluster.kubeConfig in the Helm chart deployment provider option const mysqlExporterChart = new k8s.helm.v3.Chart( "mysql-exporter", { chart: "mysql-exporter", version: "1.0.0", // replace with the version you want to deploy fetchOpts:{ repo: "http://helm-repository-url/", // replace with the URL of your Helm chart repository }, }, { provider: helmProvider } ); // Export the URL for the mysql-exporter service (if applicable) export const mysqlExporterServiceUrl = pulumi.interpolate`http://${cluster.clusterDomain}:${ mysqlExporterChart.getResourceProperty("v1/Service", "mysql-exporter-service", "spec").apply(spec => spec.ports[0].port)}/metrics`;

    This program initializes the Pulumi stack, sets up the Rancher2 and Kubernetes (Helm) providers, retrieves the desired Rancher cluster, and deploys the mysql-exporter Helm chart to that cluster.

    Here's a step-by-step explanation:

    • We begin by initializing the Rancher2 provider with the necessary API token and endpoint to connect to our Rancher server.
    • Next, we retrieve the details of the cluster we wish to deploy the chart to. This example assumes you have a specific cluster in mind named "your-cluster-name".
    • The rancher2.getCluster function is used to fetch the kubeConfig for that cluster.
    • We then create an instance of the Kubernetes (Helm) provider using the kubeConfig from our Rancher-managed cluster.
    • Using this Helm provider, we define a Pulumi Helm Chart resource that deploys the mysql-exporter chart from the specified repository.
    • Finally, we export the URL at which the mysql-exporter metrics service can be accessed, if applicable.

    Before running this program, replace placeholder values such as your-rancher-api-token, https://your-rancher-instance/v3, your-cluster-name, 1.0.0, and http://helm-repository-url/ with the actual values corresponding to your environment.

    Once this program is run with pulumi up, the mysql-exporter Helm chart will be deployed on the specified cluster within your Rancher instance.
