Kubernetes and AWS EKS Basics

Kubernetes Main Concepts

If new to Kubernetes, understand these concepts:

1. Pod: Smallest deployable unit (1+ containers)
2. Deployment: Manages replicas of pods
3. Service: Internal load balancer + DNS
4. Ingress: External load balancer (ALB)
5. ConfigMap: Configuration data
6. Secret: Sensitive data
7. HPA: Horizontal Pod Autoscaler

AWS EKS Specifics

If new to AWS EKS, know these components:

1. AWS Load Balancer Controller: Creates ALBs from Ingress
2. VPC CNI: Gives pods VPC IP addresses
3. IAM Roles for Service Accounts (IRSA): Pod-level IAM
4. EBS CSI Driver: For persistent volumes
5. CloudWatch Container Insights: For monitoring
