Kubernetes Topics - For Preparation

Foundation

• YAML Basics

Kube Core Topics

• PODs
• Deployments
• Services
• Volumes
• ConfigMaps
• Replication Controller or Replica Sets
• Declarative commands (kubectl)
• Live Template writing for PODS, Deployments & Services

AWS EKS Topics

• Create Cluster
  • AWS Management Console
  • eksctl
• Worker Nodes
  • Launch a Worker Node (Linux)
  • Managed Node Groups (MNG)
    • Updating (Patching) Managed Node Groups
    • Editing Managed Node Groups
    • Managed Node Group ERRORS
    • Deleting MNG
• Storage
  • EBS CSI Driver
  • EFS CSI Driver
• Autoscaling
  • Cluster Autoscaler
  • Horizontal Pod Autoscaler
  • Vertical Pod Autoscaler
• Load Balancing and Ingress
  • Load Balancing (CLB, NLB)
  • ALB Ingress Controller
• Networking
  • Creating a VPC for EKS
  • Cluster VPC Considerations
  • EKS Security Group Considerations
  • Understand Pod Networking
  • CoreDNS (Already exists in new clusters - just intro about it will suffice)
  • Calico (Multi-tenant environment - not needed)
• Managing Cluster Authentication (Optional)
  • Important Topic - Managing Users or IAM Roles for your cluster
• Guest Book Application
• Metrics Server
• Prometheus Metrics
• Using Helm
• Deploy Kubernetes Dashboard
• AppMesh Integration with Kubernetes
• Security (IAM role to Kubernetes Service Accounts)
  • IAM
  • Pod Security Policy
• CloudTrial
• AWS Fargate (LAST)
  • Important Note: Pods running on Fargate are only supported on private subnets (with NAT gateway access to AWS services, but not a direct route to an Internet Gateway), so your cluster's VPC must have private subnets available.
  • Stateful applications are not recommended for pods running on Fargate.
  • Daemonsets are not supported on Fargate.
  • GPUs are currently not available on Fargate.
• Troubleshooting

Monitoring & Logging
