EKS cluster creation in AWS - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Amazon EKS?

Amazon EKS (Elastic Kubernetes Service) is a managed service that makes it easy to run Kubernetes on AWS without needing to install and operate your own Kubernetes control plane.

beginner

Name the main components involved in creating an EKS cluster.

The main components are: the EKS control plane managed by AWS, worker nodes (EC2 instances or Fargate), and networking setup including VPC, subnets, and security groups.

Why do you need to create a VPC before creating an EKS cluster?

A VPC provides isolated networking for your cluster. It defines where your cluster resources run and controls communication between nodes and the internet.

beginner

What is the role of worker nodes in an EKS cluster?

Worker nodes run your containerized applications. They join the EKS cluster and communicate with the control plane to receive instructions and report status.

intermediate

How does AWS manage the EKS control plane?

AWS manages the control plane by handling the Kubernetes API servers, etcd database, and other control components, ensuring high availability and security without user intervention.

What is the first step when creating an EKS cluster?

A Configure IAM roles

B Create a VPC with subnets

C Deploy applications

D Launch worker nodes

You must first create a VPC with subnets to provide networking for your EKS cluster.

Who manages the Kubernetes control plane in EKS?

A It is managed by worker nodes

B You manage it on EC2 instances

C AWS manages it automatically

D It is managed by your local machine

AWS manages the control plane automatically, so you don't have to operate it yourself.

What do worker nodes in EKS do?

A Run your containerized applications

B Manage the Kubernetes API

C Store cluster configuration

D Provide internet access

Worker nodes run the containers that make up your applications.

Which AWS service is used to create and manage EKS clusters?

A Amazon CloudFront

B Amazon S3

C Amazon RDS

D Amazon EKS

Amazon EKS is the service specifically designed to create and manage Kubernetes clusters.

What is required for worker nodes to join an EKS cluster?

A Proper IAM roles and security group settings

B A public IP address only

C Manual installation of Kubernetes control plane

D Direct access to AWS console

Worker nodes need correct IAM roles and security groups to communicate securely with the cluster.

Explain the process of creating an EKS cluster from scratch.

Think about networking, permissions, control plane, nodes, and access.

Describe the roles of the control plane and worker nodes in an EKS cluster.

Focus on management vs. execution roles.
