Deploy the prometheus-webhook-dingtalk helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the Prometheus Webhook Dingtalk Helm chart on a Kubernetes cluster managed by Rancher, you'll first need to ensure you have a Rancher Kubernetes cluster configured and accessible. The deployment will involve the following key steps:

Set up the Kubernetes cluster in Rancher.
Install the Prometheus Webhook Dingtalk Helm chart on the cluster.

For step 1, using Pulumi, you create a Rancher cluster resource. Given that your prompt implies that you already have a Rancher setup, I will skip this step and proceed to step 2, where you use the rancher2 Pulumi provider to manage resources in Rancher.

Here is a Pulumi TypeScript program that demonstrates how to deploy the Prometheus Webhook Dingtalk Helm chart to your existing Rancher-managed Kubernetes cluster:

import * as pulumi from "@pulumi/pulumi";
import * as rancher2 from "@pulumi/rancher2";
import * as k8s from "@pulumi/kubernetes";

// Note: These values are placeholders and should be replaced with your actual cluster details.
const clusterId = "my-cluster-id"; // Replace with your actual Cluster ID in Rancher.
const projectId = "my-project-id"; // Replace with the Project ID where the Helm chart will be installed.

// Initialize the Rancher provider.
const rancherProvider = new rancher2.Provider("rancher", {
    apiUrl: "https://your-rancher-instance.com/v3", // Replace with your actual Rancher URL
    tokenKey: "your-rancher-token", // Replace with your actual Rancher Bearer Token.
});

// Initialize the Kubernetes provider.
const k8sProvider = new k8s.Provider("k8s", {
    kubeconfig: rancher2.cluster.kubeConfig(clusterId),
}, { provider: rancherProvider });

// Deploy Prometheus Webhook Dingtalk Helm chart.
const dingtalkHelmChart = new k8s.helm.v3.Chart("prometheus-webhook-dingtalk", {
    chart: "prometheus-webhook-dingtalk",
    version: "1.0.0", // Specify the chart version you want to deploy.
    fetchOpts: {
        repo: "https://prometheus-community.github.io/helm-charts", // Helm chart repository URL.
    },
    values: {
        // Specify your values according to the Helm chart's requirements.
        // This is an example, customize these values for your actual use case.
        dingtalk: {
            webhook: "<YOUR_WEBHOOK_URL>",
            secret: "<YOUR_SECRET>",
        },
        // Other values as required by the chart...
    },
}, { provider: k8sProvider });

// Export the base URL of the Dingtalk notifier service.
export const dingtalkNotifierUrl = dingtalkHelmChart.getResourceProperty("v1/Service", "prometheus-webhook-dingtalk", "status").apply(status => status.loadBalancer.ingress[0].ip);

Before running this program, make sure you have configured your Pulumi CLI with the appropriate credentials for both Rancher and your Kubernetes cluster. The above example assumes you have a working Rancher setup and access to its API.

The rancher2.Provider is initialized by specifying the API URL and the access token, which will allow Pulumi to communicate with your Rancher instance. This is crucial for Pulumi to perform operations on your behalf within the Rancher platform.

The k8s.Provider is then constructed using the kubeconfig provided by Rancher, as fetched from the rancher2.cluster.kubeConfig function. This kubeconfig is necessary for the Kubernetes provider to communicate with the Kubernetes API server.

The Prometheus Webhook Dingtalk chart is then deployed using the k8s.helm.v3.Chart resource with the specified chart and version. You'll need to replace <YOUR_WEBHOOK_URL> and <YOUR_SECRET> with the actual values for the Dingtalk webhook you intend to use. Additional chart values may also be provided, as per the Prometheus Webhook Dingtalk Helm chart's documentation.

Finally, the program exports the IP address of the Service created by the Helm chart, which you can use to access the Dingtalk notifier service from outside the cluster.

To run this program, execute it with the Pulumi CLI, which will provision the defined resources in your specified cluster:

pulumi up

Please replace all placeholder values with your actual Rancher and Helm chart details to ensure the program works correctly in your environment.
