  7. EKS Source: Instana

  8. IAM Authentication apiVersion: v1 kind: ConfigMap metadata: name: aws-auth namespace:

    kube-system data: mapRoles: | - rolearn: worker-role username: system:node:{{EC2PrivateDNSName}} groups: - system:bootstrappers - system:nodes - rolearn: ci-role username: admin:{{SessionName}} groups: - system:masters - rolearn: ops-guy Username: admin:{{SessionName}} groups: - system:masters
  9. Access to AWS services kube2iam IAM Roles for Service Accounts

  10. Requirements

  11. Networking

  12. Master Plane

  13. None
  14. None
  15. None
  16. Worker Nodes

  17. None
  18. Automatic Deployments

  19. None
  20. AWS Cloudformation

  21. None
  22. None
  23. Differences Cloudformation does not support all settings e.g. Logs, Private

    Networking eksctl separate tool - not really IaaS and isolated from Cloudformation Terraform multi-cloud compatible and most feature rich
  24. Feature Comparison Cloudformation Terraform eksctl State management Cluster creation Add

    IAM user Auto scaling VPC Cluster config Cluster services upgrade Config Control plane logging
  25. Non-functional Comparison Cloudformation Terraform eksctl Release velocity Deployment velocity Support

    API Stability Extendability
  26. Self managed Node Groups vs managed Node Groups

  27. Advantages Managed Nodegroups Easier creation Health monitoring through EKS API

    Node draining Upgrade cluster versions Rolling update Force update
  28. No automatic patches No custom AMI - only Amazon Linux

    Can only change size of root volume No spot instances and one instance type per group No kubelet customization Disadvantages of Managed Nodegroups
  29. Scaling Change DesiredSize and MaxSize of Managed Nodegroups Update Stack

    Can also use Cluster Autoscaler
  30. Cluster Upgrades Update release version in managed nodegroup to upgrade

    cluster Change of value in config Use button in Console Update cluster services
  31. Logging Multiple ways Fluentd to Cloudwatch Fluentd to ELK stack

    Managed Logging service e.g. Datadog
  32. AppMesh

  33. Recommendations Choose solution based on your current IaaS tooling Quick

    prototyping with eksctl Terraform most feature-rich for third-party services
