Userdata is compatible with the standard AWS EKS Terraform module, with the sole recommendation being the utilization of a custom AMI. In order to use instance-store you also need to install local-static-provisioner - https://github.com/kubernetes-sigs/sig-storage-local-static-provisioner Terraform example: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 eks-dev-instance-store = { instance_types = ["r6id....

There are numerous solutions for accessing private RDS instances, many of which require thoughtful design. The solution I use sometimes is straightforward: I deploy it as a Helm chart within a k8s cluster. In this setup, access to the RDS is contingent on having access to the k8s cluster with the appropriate RBAC configurations. While it may not be perfect, it’s secure, quick to implement, and requires minimal maintenance. The following command demonstrates the basic principle:...

You can now launch NAT Gateways in your VPC without associating an internet gateway to your VPC. Internet Gateway is required to provide internet access to the NAT Gateway. However, some customers use their NAT Gateways with Transit Gateway or virtual private gateway to communicate privately with other VPCs or on-premises environments and thus, do not need an internet gateway attached to their VPCs.

Amazon EC2 Auto Scaling now natively supports Predictive Scaling so you can proactively scale out your Auto Scaling group to be ready for upcoming demand. Predictive Scaling can help you avoid the need to over-provision capacity, resulting in lower EC2 cost, while ensuring your application’s responsiveness. (Previously, Predictive Scaling was only available via AWS Auto Scaling Plans.) https://aws.amazon.com/about-aws/whats-new/2021/05/amazon-ec2-auto-scaling-introduces-predictive-scaling-native-scaling-policy/

Amazon Elastic Kubernetes Service (Amazon EKS) now supports using the Amazon EKS console, CLI, and API to install and manage CoreDNS and kube-proxy in addition to existing support for the Amazon VPC CNI networking plugin. https://aws.amazon.com/about-aws/whats-new/2021/05/eks-add-ons-now-support-coredns-kube-proxy/ https://docs.aws.amazon.com/eks/latest/userguide/eks-add-ons.html

Amazon EC2 enables you to replace the root EBS volume for a running instance Limitations: You can’t replace the root volume if it is an instance store volume. You can’t replace the root volume for metal instances.
