1. Deploy the music helm chart on AWS EKS


    In order to deploy a Helm chart on AWS Elastic Kubernetes Service (EKS), you need to create an EKS cluster, configure the Kubernetes provider to interact with the cluster, and then deploy the Helm chart to it. We'll leverage the awsx and kubernetes packages to accomplish this task. Here's a step-by-step guide along with the Pulumi program written in TypeScript.

    Step 1: Setting up an AWS EKS Cluster

    First, we will set up an AWS EKS Cluster using the awsx package, which provides higher-level abstractions that make it easier to specify an EKS cluster. You need to define the VPC and subnet IDs to deploy the EKS cluster in your AWS environment, and an IAM role for the EKS service. For simplicity, we assume the VPC and subnet have been configured, and the IAM role exists.

    Step 2: Configuring the Kubernetes Provider

    After setting up the EKS cluster, we need to configure the Kubernetes provider so that we can deploy resources in our cluster. The provider uses the kubeconfig that we obtain from the EKS cluster to communicate with your Kubernetes cluster.

    Step 3: Deploying a Helm Chart

    Once the provider is configured, we can now deploy Helm charts. In this case, we will deploy a generic "music" Helm chart. You will need the name of the Helm chart and optionally the chart version and values you want to override.

    Here's a Pulumi program that accomplishes the deployment:

    import * as pulumi from "@pulumi/pulumi"; import * as awsx from "@pulumi/awsx"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an EKS cluster const cluster = new eks.Cluster('my-eks-cluster', { // ... other configuration like VPC and subnet IDs, IAM Roles ... }); // Step 2: Configure the Kubernetes provider to deploy resources in the created EKS cluster const provider = new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Step 3: Deploy the 'music' Helm chart into the EKS cluster const musicChart = new k8s.helm.v3.Chart('music-chart', { chart: 'music', // version: '1.0.0', // Optional: specify the chart version // values: { /* ... */ }, // Optional: override chart values }, { provider }); export const kubeconfig = cluster.kubeconfig; export const musicChartStatus = musicChart.status;

    In the program above:

    • We create an eks.Cluster which initializes the EKS cluster.
    • We then instantiate a kubernetes.Provider which will enable us to deploy Kubernetes resources in that cluster.
    • We then deploy the music Helm chart via k8s.helm.v3.Chart where you can specify the chart name, version, and values to customize it.
    • Two outputs kubeconfig and musicChartStatus are exported, which can be used to retrieve the Kubernetes configuration and to check the status of the deployed Helm chart respectively.

    Please make sure that you have set up the AWS credentials on your local machine or in your environment where Pulumi will be running. This will allow Pulumi to create and manage resources within your AWS account.

    You can run this Pulumi program by saving it into a file with a .ts extension and executing it using the Pulumi CLI. After running pulumi up, Pulumi will show you a preview of the resources that will be created. If everything looks correct, confirm the deployment to create the resources in AWS.

    Note: Be sure to replace placeholder values with actual values for your chart, VPC configuration, IAM roles, and other required resources. The chart name 'music' is used as an example, and you need to replace it with the actual chart name you intend to deploy. If your Helm chart is located in a specific Helm repository, you'll need to provide the repo property with the URL of the repository.
