1. Deploy the prometheus-webhook-dingtalk helm chart on AWS EKS


    To deploy the prometheus-webhook-dingtalk Helm chart on AWS EKS using Pulumi, you'll have to perform several steps. First, you need to create an EKS cluster if you don't have one already. Then, you'll need to set up the required configurations to deploy a Helm chart into that cluster. The Helm chart will be installed on the Kubernetes cluster created by EKS.

    Below is an outline of the process along with the Pulumi TypeScript program:

    1. Set up an AWS EKS Cluster: This is where your Kubernetes applications will run. Pulumi provides a high-level component eks.Cluster which simplifies the creation of an EKS cluster.
    2. Install the Helm Chart: Pulumi's kubernetes.helm.v3.Chart resource allows you to deploy Helm charts into your Kubernetes cluster.

    Here is the Pulumi TypeScript program that outlines these steps:

    import * as pulumi from '@pulumi/pulumi'; import * as aws from '@pulumi/aws'; import * as awsx from '@pulumi/awsx'; import * as eks from '@pulumi/eks'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create an EKS cluster. This code sets up an EKS cluster with default configurations. const cluster = new eks.Cluster("my-cluster", { desiredCapacity: 2, minSize: 1, maxSize: 2, // Specify additional settings here if needed. }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Step 2: Deploy the prometheus-webhook-dingtalk Helm chart into the EKS cluster. // Instantiate a Kubernetes provider instance using the kubeconfig from the EKS cluster. const provider = new k8s.Provider("provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Create a Helm chart instance using the Kubernetes provider. const prometheusWebhookChart = new k8s.helm.v3.Chart("prometheus-webhook-dingtalk", { chart: "prometheus-webhook-dingtalk", version: "1.0.0", // Specify the chart version if necessary. fetchOpts: { repo: "https://your-helm-chart-repository/", // Specify your Helm chart repository URL. }, // Specify your Helm chart values here if needed. }, { provider }); // Export the name of the deployed Helm chart. export const chartName = prometheusWebhookChart.id;

    Understanding the code:

    • The eks.Cluster class creates an EKS cluster with the specified number of nodes (desiredCapacity). The cluster will automatically scale between minimum (minSize) and maximum (maxSize) count based on demand.

    • The new k8s.Provider line creates a Kubernetes provider instance that lets Pulumi communicate with the cluster.

    • The new k8s.helm.v3.Chart line deploys the Helm chart to the Kubernetes cluster, where you specify the chart name, version, and repository URL. If prometheus-webhook-dingtalk requires any specific values to be set, you can do that by passing an appropriate values object.

    Next Steps:

    • Replace "https://your-helm-chart-repository/" with the actual repository URL where the prometheus-webhook-dingtalk chart is located.

    • Add any required configurations for the Helm chart in the values property if needed.

    • Run pulumi up to deploy the EKS cluster and the Helm chart. Make sure your Pulumi CLI is set up and properly configured with AWS credentials.

    • After deployment, the EKS cluster's kubeconfig is exported, which can be used to manage your Kubernetes cluster with kubectl.

    You now have a fully functioning AWS EKS cluster with the prometheus-webhook-dingtalk Helm chart deployed on it.
