AWS Kubernetes: A Comprehensive Guide
AWS Kubernetes: A Comprehensive Guide
AWS Kubernetes offers a powerful way to manage containerized applications. Combining Kubernetes, an open-source container orchestration tool, with the robust infrastructure of AWS presents a dynamic solution for developers and operations teams alike. Let’s explore the key concepts, setup instructions, and best practices associated with using Kubernetes on AWS.
Understanding Kubernetes
Kubernetes automates the deployment, scaling, and operation of application containers across clusters of hosts. Instead of managing individual containers, Kubernetes manages clusters, simplifying operations. It schedules containers, balances workloads, and handles failovers. This self-healing system minimizes downtime and ensures consistent performance.
What is Amazon EKS?
Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service offered by AWS. It simplifies running Kubernetes on AWS without needing to install and operate your own Kubernetes control plane. EKS automatically manages the availability and scalability of the Kubernetes control plane nodes responsible for scheduling containers, running talents, and managing the application’s desired state.
Setting Up EKS
Prerequisites
- AWS account with necessary permissions
- kubectl command-line tool
- AWS CLI
- eksctl command-line tool
Creating an EKS Cluster
Install and configure the AWS CLI. Ensure it’s connected to your AWS account and that you have the required IAM permissions. Install eksctl, a command-line tool for simplifying EKS cluster creation.
