Deploy the rollout helm chart on AWS EKS
TypeScriptTo deploy the rollout helm chart on AWS EKS, we need to perform a few steps. First, we will create an AWS EKS cluster and then deploy the rollout helm chart to the EKS cluster. Below is a Pulumi program written in TypeScript that does exactly this.
Here's how we'll proceed:
- Set up an EKS cluster using the Pulumi AWS and EKS providers.
- Create an IAM role for the EKS cluster so that Kubernetes can access other AWS services.
- Provision the EKS cluster with the required configuration.
- Use the Kubernetes provider to deploy the rollout helm chart to the EKS cluster.
Let's dive into the code:
import * as aws from "@pulumi/aws"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS Cluster. // Check the documentation for additional options and details: https://www.pulumi.com/docs/reference/pkg/aws/eks/cluster/ const cluster = new eks.Cluster("cluster", { // specify the IAM role if you have one, else EKS will create one for you. // vpcConfig specifies the VPC subnets and security groups for the EKS cluster. // Define the version of Kubernetes you want to deploy. version: "1.21", }); // Deploy the rollout helm chart on the EKS cluster. // See the Pulumi Kubernetes provider documentation for helm charts: https://www.pulumi.com/docs/reference/pkg/kubernetes/helm/v3/chart/ const rolloutChart = new k8s.helm.v3.Chart("rollout", { chart: "rollout", // "repo" would be the repository that houses the rollout helm chart, if it's a custom one or not from the stable repo fetchOpts: { repo: "https://charts.your-repository.com/", }, // version can be omitted to get the latest or you can specify the exact version of the helm chart. namespace: "default", }, { provider: cluster.provider }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig;
This program performs the following actions:
- It imports the required Pulumi packages for working with AWS, EKS, and Kubernetes resources.
- A new EKS cluster is created using
eks.Cluster
.- The
version
field specifies the Kubernetes version. - If you need to customize the VPC or subnets, that would be done in the
vpcConfig
option, which is not shown here but can be added as required.
- The
- A helm chart for the rollout is then deployed using
k8s.helm.v3.Chart
.- The
chart
argument specifies the name of the chart to deploy. - The
fetchOpts.repo
may need to be modified to point to the helm chart's repository if it's not a standard Helm chart available in the default repositories. - The
namespace
argument specifies which namespace in the Kubernetes cluster you want to deploy the chart to. Here we're using"default"
, but this can be any namespace you wish.
- The
- Finally, the kubeconfig of the created EKS cluster is exported. This allows you to interact with your cluster using
kubectl
.
Please note: Before running this program, you should have the Pulumi CLI installed, AWS credentials configured on your machine, and an AWS Pulumi provider set up. To deploy a different Helm chart or a specific version, you would just change the
chart
andversion
parameters respectively.
