1. Deploy the apollo helm chart on AWS EKS


    Deploying an Apollo server instance on AWS EKS using a Helm chart involves a few steps:

    1. Set up an EKS Cluster: This is where your Kubernetes services and workloads will run. EKS is a managed Kubernetes service that simplifies running Kubernetes on AWS.

    2. Configure and Install Helm: Helm is a package manager for Kubernetes that allows you to define, install, and upgrade complex Kubernetes applications.

    3. Deploy the Apollo Chart: Once the EKS cluster is running and Helm is set up, you can deploy the Apollo server using an existing Helm chart.

    Here's a Pulumi program that illustrates these steps using TypeScript:

    import * as eks from "@pulumi/eks"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("my-cluster", {}); // Export the cluster's kubeconfig and EKS endpoint export const kubeconfig = cluster.kubeconfig; export const clusterEndpoint = cluster.core.cluster.endpoint; // Once the cluster is created, you can configure the Kubernetes provider to use the cluster's kubeconfig const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the Apollo Helm chart using the Kubernetes provider const apolloChart = new k8s.helm.v3.Chart("apollo-server", { chart: "apollo-server", // Replace this with the actual Helm repo URL or a local path to the chart repo: "https://apollo-server-helm-repo.com/", version: "3.0.0", // Replace with the appropriate chart version namespace: "default", }, { provider }); // Export the name of the chart export const chartName = apolloChart.name;

    To break down what the above code does:

    • Firstly, we create an EKS cluster using Pulumi's EKS module. We name the cluster "my-cluster" and use the default configuration, which is sufficient for many use cases. Refer to the eks.Cluster documentation for more advanced configurations.

    • We then export the kubeconfig for the newly created cluster. This configuration allows kubectl and other Kubernetes tools to talk to your EKS cluster.

    • Next, we set up a Kubernetes provider, telling Pulumi how to communicate with the EKS cluster. A Pulumi provider uses the kubeconfig file from the EKS cluster to interact with it.

    • Finally, we deploy the Apollo server using a Helm chart. We specify the name of the chart, apollo-server, and provide the repository URL hosting the chart. Ensure that you replace https://apollo-server-helm-repo.com/ with the actual repository URL and the version with the correct Helm chart version you wish to use.

    • After defining the apolloChart, we export the name of the chart for easy reference.

    To run this program, you'll need to have Pulumi installed and AWS credentials configured. Additionally, specify the Helm chart repository and version that hosts the Apollo server chart you wish to install.

    Please note that you must have access to the Helm repository you're referring to in the program, and it must contain an apollo-server chart. If you have a custom or private Helm chart for Apollo server, provide the correct chart, version, and repo.

    Once the program is ready, you can use Pulumi to deploy your infrastructure as follows:

    1. Install Pulumi on your machine (refer to the Pulumi Installation Guide).
    2. Configure the AWS CLI and authenticate with your AWS account (refer to Configuring the AWS CLI).
    3. Navigate to the directory where you've saved the above Pulumi TypeScript program.
    4. Run pulumi up and follow the prompts to deploy your cluster and the Apollo server.
