Deploy the cert-manager-webhook-namecheap helm chart on AWS EKS
TypeScriptTo deploy the
cert-manager-webhook-namecheap
Helm chart on AWS EKS, you will need to carry out several steps. Below is a breakdown of the tasks:- Set up an EKS Cluster: This is a managed Kubernetes service that will run your Kubernetes applications.
- Create an ECR Repository: Although not directly related to deploying the Helm chart, it's common practice to have a container registry where you can store container images used by workloads running on EKS.
- Deploy Helm Chart: Using the Helm provider in Pulumi, you can easily deploy third-party Helm charts like
cert-manager-webhook-namecheap
.
For this Pulumi program, I'll use the
@pulumi/eks
module to create an EKS cluster, and the@pulumi/kubernetes
module to configure Kubernetes resources and deploy our Helm chart.Here is a Pulumi TypeScript program that performs these tasks:
-
Imports and setup: We'll first import the Pulumi packages required for AWS, EKS, and Kubernetes.
-
Create an EKS Cluster: We'll create an EKS Cluster resource, defining its size, and specifying the version of Kubernetes to use.
-
Deploy the Helm Chart: Using the
helm.v3.Chart
resource from Pulumi's Kubernetes provider, we'll deploy thecert-manager-webhook-namecheap
chart.
import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; import * as aws from "@pulumi/aws"; // Create an EKS cluster. const cluster = new eks.Cluster("my-cluster", { desiredCapacity: 2, minSize: 1, maxSize: 2, storageClasses: "gp2", // Using general purpose SSD storage version: "1.21", // Specify your desired Kubernetes version here, e.g., "1.21" }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Set up a provider to use the newly created cluster's kubeconfig. const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the 'cert-manager-webhook-namecheap' Helm chart. // Note: You need to add the Helm repository that contains the chart and update your local Helm repository cache. // e.g. helm repo add <name> <url> const certManagerWebhookNamecheapChart = new k8s.helm.v3.Chart("cert-manager-webhook-namecheap", { chart: "cert-manager-webhook-namecheap", version: "x.y.z", // use the appropriate chart version // Assuming that 'cert-manager' is already set up. // The 'values' property specifies the configuration values for the Helm chart. values: { // Provide necessary values here. }, }, { provider }); // Export the Helm chart resources. export const chartResources = certManagerWebhookNamecheapChart.resources;
Explanation:
- We import necessary Pulumi libraries for interacting with AWS, EKS, and Kubernetes.
- We define an EKS cluster with
eks.Cluster
specifying the desired number of worker nodes, storage class, and Kubernetes version. - The
kubeconfig
output from our EKS cluster is exported. This will allow our localkubectl
to interact with the cluster. - Then, we set up a Kubernetes provider that utilizes the
kubeconfig
from the created EKS cluster. This provider is used for Helm charts and other Kubernetes resources. - A
k8s.helm.v3.Chart
resource namedcert-manager-webhook-namecheap
is created, pointing to the correct Helm chart by name. This chart is expected to be on a Helm chart repository accessible from your setup. - The
values
property specifies the necessary values to configure the Helm chart. You would need to fill this in based on thecert-manager-webhook-namecheap
chart's documentation and your specific needs. - We export the resources of the Helm chart so that you can observe their status with the
pulumi up
command output.
Important Notes:
- Before deploying this chart,
cert-manager
must be installed in your cluster as it is a prerequisite. You can also installcert-manager
via Helm using Pulumi if it's not already present in your cluster. - You will need to replace the placeholder in the
version
field with the actual chart version you want to deploy. - Also, replace the
values
with the appropriate configuration for your instance ofcert-manager-webhook-namecheap
.
This Pulumi program should be run in a directory where you have created a Pulumi project. After running
pulumi up
, Pulumi will perform the necessary steps to deploy the resources to AWS. Make sure you have installed and configured AWS CLI with the appropriate credentials and have the Pulumi CLI installed and logged in.
