Amazon Elastic Kubernetes Service (EKS) for Beginners

Create a Cloud9 workspace to access a browser-based terminal that deploys and manages an EKS cluster, spinning up a secure EC2 dev environment for hands-on labs.

Create an IAM role with administrator access and attach it to the Cloud9 workspace to enable launching an e-commerce cluster, then export account id and region and configure default region.

Launch an Amazon EKS cluster using the ECA CDL tool, create a dedicated VPC, initialize the control plane and worker nodes, and verify connectivity with kubectl.

Learn how to scale an EKS cluster by adjusting node group capacity and by adding new node groups, including scaling up from 2 to 4 and scaling down to 2.

Deploy the official dashboard with the dashboard YAML and kubectl apply, then connect from your Cloud9 workspace via a proxy and authenticate with an IAM token to manage workloads.

Clone the course’s GitHub repository into your Cloud9 environment to access all deployment YAML files, or manifests, describing the microservices you’ll deploy to the cluster.

Deploy the engine X app with a YAML deployment specifying name, replicas, selectors, and port 80. Expose it via a load balancer service with a readiness probe for rolling updates.

Launch the NGINX app on EKS by creating a deployment and a load balancer service. Verify replicas and endpoints, test with curl to the external load balancer.

Calculate monthly costs for a two-node e-commerce EKS cluster, including data and control planes, and reduce expenses by deleting the cluster when idle using the delete cluster command.

Learn how volumes, persistent volumes, and persistent volume claims enable data persistence outside container roots, preserving data across restarts and enabling mounting via claims.

Create persistent volume claims using a storage class in Amazon EKS, with gp2 as default, enabling dynamic provisioning and mounting of MySQL and WordPress volumes into their pods.

Create a cluster-internal MySQL service in Kubernetes by applying the mysql-service file, exposing port 3306 via cluster IP, and verifying the endpoint IP matches the backend pods for WordPress integration.

Deploy a WordPress pod on Kubernetes using a WordPress YAML file, configuring WordPress to connect to a MySQL service with environment variables, mounting a persistent volume, and verifying deployment.

Create a namespace and deploy Nginx on Amazon Elastic Kubernetes Service, using kubectl to apply the deployment and verify all pods run in the new namespace.

Create an IAM user, generate access keys, and save credentials to a file to test role-based access control.

Create an IAM user to EKS user mapping with a config map, substitute your account ID, apply the config map, source credentials, and verify access before moving to rule binding.

Create a reader role in the outback namespace and bind it to the outback user, granting get, list, and watch access to ports and deployments.

Explore Helm's core concepts—charts, config, releases, and repositories—and learn how the Helm client and library interact with the Kubernetes API to install charts on EKS.

Install Helm on an EKS cluster using the official script, verify the install, add the stable chart repository, and search for charts to deploy.

Update helm repositories, search and add the bitnami engine X chart, install the release my engine X, verify status, test the service, and uninstall the release.

Learn to customize a helm chart by viewing default values with helm show values, creating a config file, and overriding replicaCount and image.tag during install.

Upgrade your helm release by applying a new configuration, verify with get values, track revisions with history, and rollback to a previous release or uninstall if needed.

Create a WordPress helm chart by scaffolding chart.yaml, values.yaml, and a templates directory, then adapt templates with Go template language and override values with -f during install.

Package and install a WordPress chart on EKS by editing values.yaml, applying templates, and using helm to lint, render, package, deploy, test, and clean up.
