Deploy the mysql-persistent helm chart on AWS EKS
TypeScriptTo deploy the
mysql-persistent
Helm chart on an AWS EKS cluster using Pulumi, we need to execute several steps, which include the following:- Create an EKS cluster.
- Deploy the
mysql-persistent
Helm chart onto the cluster.
For the first step, we'll use the
eks.Cluster
class from the@pulumi/eks
package, which is a higher-level component that simplifies the creation of an EKS cluster.For the second step, we'll use the
kubernetes.helm.v3.Chart
class from the@pulumi/kubernetes
package, which allows us to deploy Helm charts on a Kubernetes cluster managed by Pulumi.Here's a step-by-step explanation of the Pulumi TypeScript program that accomplishes these tasks:
- Import the necessary modules: We need to import the Pulumi EKS and Kubernetes packages to create the resources.
- Create an EKS cluster: We instantiate an EKS cluster with the required properties.
- Deploy the Helm chart: Once the cluster is provisioned, we deploy the
mysql-persistent
Helm chart using the Chart resource.
Below is the complete TypeScript program, which you should place in an
index.ts
file. You should have installed Pulumi and set up the AWS credentials on your machine before running this program.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; // Create a provider for the EKS cluster. const provider = new k8s.Provider("provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the mysql-persistent Helm chart. const mysqlPersistent = new k8s.helm.v3.Chart("mysql-persistent", { repo: "stable", // You may need to change the repo to the one that contains your desired chart chart: "mysql", version: "1.6.9", // Use the correct version for the mysql-persistent chart // Use appropriate values for your MySQL deployment. values: { persistence: { enabled: true, size: "10Gi", }, // Further configuration according to your requirements. }, }, { provider }); // Export the MySQL Service endpoint export const mysqlService = mysqlPersistent.getResource("v1/Service", "mysql-persistent-mysql");
This is what the code does:
- We define a new EKS cluster with the desired number of nodes.
- The Kubernetes provider is instantiated using the kubeconfig from the newly created cluster.
- We deploy the
mysql-persistent
Helm chart to this cluster with some custom values. Specifically, we enable persistence and set the persistent volume size to 10Gi. Adjust thevalues
based on themysql-persistent
Helm chart's values.yaml and your requirements. - The export statements are useful for fetching the kubeconfig and the MySQL service endpoint outside of Pulumi for use with kubectl or in your applications.
To deploy this program, save it in a file named
index.ts
in a new Pulumi project directory, then runpulumi up
from your command line in the same directory.Please note that the
stable
Helm repo might not be maintained anymore, as the Helm community deprecated it. You should find an updated source for yourmysql-persistent
chart or use a chart provided directly by a cloud service's Helm repository. The version1.6.9
is used as a placeholder, and you should replace it with the version you intend to deploy.Also, remember that provisioning an EKS cluster can incur costs on AWS. Be sure to destroy the cluster with
pulumi destroy
if it's no longer needed.
