1. Deploy the argocd-instance helm chart on AWS EKS

    TypeScript

    To deploy the argocd-instance Helm chart on AWS EKS using Pulumi, you will follow these steps:

    1. Create an EKS cluster.
    2. Deploy the argocd-instance Helm chart to the EKS cluster.

    To achieve step 1, we'll use the eks.Cluster resource from the eks package as it provides a high-level abstraction for managing EKS clusters. This abstracts away many of the details for creating an EKS cluster, making it simpler to use, especially for novices.

    For the second step, the kubernetes.helm.sh/v3.Chart resource from the kubernetes package will enable you to deploy a Helm chart onto a Kubernetes cluster.

    Let's begin with a complete Pulumi TypeScript program that defines both these resources:

    import * as pulumi from '@pulumi/pulumi'; import * as eks from '@pulumi/eks'; import * as k8s from '@pulumi/kubernetes'; // Create an EKS cluster. const cluster = new eks.Cluster('my-cluster', { desiredCapacity: 2, minSize: 1, maxSize: 3, storageClasses: "gp2", deployDashboard: false, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Use the kubeconfig from the generated EKS cluster to interact with the cluster's Kubernetes API server. const k8sProvider = new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the argocd-instance Helm chart on the EKS cluster. const argoCDChart = new k8s.helm.sh.v3.Chart('argo-cd', { chart: 'argo-cd', version: '3.2.3', // replace with the desired chart version fetchOpts:{ repo: 'https://argoproj.github.io/argo-helm', }, }, { provider: k8sProvider });

    Here is what each part of the program does:

    • eks.Cluster creates an EKS cluster, with the desired, minimum, and maximum number of worker nodes indicated. The storage classes for persistent storage are set, and the Kubernetes dashboard is not deployed for security reasons.

    • Exporting kubeconfig allows you to interact with your cluster using the kubectl command-line tool once the Pulumi program completes.

    • k8s.Provider is a Pulumi resource representing a Kubernetes provider that uses the generated kubeconfig to interact with the EKS cluster we just created.

    • k8s.helm.sh/v3.Chart is used to deploy the argo-cd Helm chart to the Kubernetes cluster. Replace '3.2.3' with the desired version of the Helm chart you want to deploy. The repo option specifies the Helm repository where the argo-cd chart can be found.

    Before you start, ensure that you have Pulumi CLI installed, your AWS credentials configured for Pulumi, and Helm CLI installed for Helm operations if needed.

    Lastly, execute pulumi up to create the resources as defined. Pulumi will perform the deployment, and once done, you can use the argo-cd service on your new EKS cluster.
