1. Deploy the mysql8 helm chart on AWS EKS


    To deploy the MySQL 8 Helm chart on AWS EKS (Elastic Kubernetes Service), you need to follow these steps:

    1. Create an EKS Cluster: You will need a running EKS cluster where you can deploy your applications. You can use Pulumi's eks package to create one.

    2. Install the Helm Chart for MySQL: Once the cluster is available, you can use Pulumi's kubernetes provider to deploy MySQL from its Helm chart.

    Here is a detailed breakdown of each step in TypeScript using Pulumi:

    Step 1: Create an EKS Cluster

    First, we will set up an EKS cluster. We'll use the eks.Cluster class to create a new cluster. This will set up all of the necessary resources for an EKS cluster, such as the VPC, security groups, IAM roles, and more.

    Step 2: Deploy MySQL with Helm Chart

    After the cluster is up and running, we will deploy the MySQL Helm chart. We will use the kubernetes.helm.v3.Chart resource which allows us to specify the chart we want to install, along with any values we want to override in the chart's default configuration.

    Now, let's look at the program:

    import * as pulumi from "@pulumi/pulumi"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster with the default configuration const cluster = new eks.Cluster("my-cluster", { desiredCapacity: 2, minSize: 1, maxSize: 2, instanceType: "t2.medium", }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes provider that uses the generated kubeconfig const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy MySQL 8 using the Helm chart const mysqlChart = new k8s.helm.v3.Chart("mysql-chart", { chart: "mysql", version: "8.0.26", // specify the chart version you want to deploy fetchOpts: { // replace with the URL to your chart repository if it's not in a public repository repo: "https://charts.bitnami.com/bitnami", }, values: { // Values to override in the chart, if necessary // Refer to the chart's values.yaml file for a full list of configurable options imageTag: "8.0.26", auth: { rootPassword: "my-secret-pw", // Change this to a secure password // You can also set other authentication parameters here }, // Specify any other custom settings here }, }, { provider }); // Export the name of the chart so we can see that it was created export const mysqlChartName = mysqlChart.metadata.apply(m => m.name);

    Make sure to change any values like usernames, passwords, etc., to the desired ones in a secure manner. In the auth section within the values, I've used a placeholder value for rootPassword which you should change to something secure.

    Notice that we export the kubeconfig and the Helm chart name. The kubeconfig will allow you to interact with your EKS cluster using kubectl, and the exported chart name confirms that the MySQL chart has been deployed.

    To run this program, you need to have Pulumi installed and configured for AWS access. Place this code in a index.ts file, and run pulumi up to create the resources. When you are prompted, review the changes Pulumi plans to make and then confirm the update.

    Remember to follow security best practices such as securing your kubeconfig file and using secrets management for sensitive information like the root password.
