This week we’ll discuss the availability of Kubernetes version 1.22 across the Amazon EKS product line, what to do to get ready for Kubernetes 1.24 (the upstream release is coming soon), and a tool called PacketStreamer, which is intended to help you do packet captures of network traffic from multiple remote sources.
Amazon EKS, Amazon EKS Distro, and Amazon EKS Anywhere now support Kubernetes version 1.22
- You can now use Amazon EKS, Amazon EKS Distro, and Amazon EKS Anywhere to run Kubernetes version 1.22
- Kubernetes version 1.22 release includes external credential providers, server-side apply, and bound service account token volumes graduating to stable, and warning mechanisms for deprecated API usage
- Kubernetes 1.22 removes a number of deprecated beta APIs in favor of GA versions of those same APIs. You need to ensure your applications, add ons, manifests and clients are updated to use these GA APIs to prevent workloads from potentially failing after the upgrade is complete.
Amazon EKS now supports Kubernetes 1.22
- The theme for the release, according to release lead Savitha Raghunathan, is due to what she described as: “in spite of the pandemic and burnout, Kubernetes 1.22 had the highest number of enhancements in any release.”
- Amazon EKS team worked hand-in-hand with etcd contributors to help verify and consistently reproduce data inconsistency issues (we’re shipping version 1.22 with etcd 3.4 as a result pending a release that mitigates these issues).

Introducing PacketStreamer: distributed packet capture for cloud-native platforms
- PacketStreamer is an open-source tool that captures network traffic from multiple remote sources concurrently and aggregates the data into a single pcap log file
- Observing network traffic can reveal attacker behaviors before a successful compromise, such as reconnaissance activity and weaponization that is targeted at specific vulnerabilities
- With PacketStreamer, you can extend your traffic capture activities to span large numbers of target systems
Amazon EKS, AWS CDK, and Go
- Go support is currently still in Developer Preview
- Support for other languages is done through generating bindings with jsii
- Amazon EKS Developer Advocate, Jimmy Ray, walks us down his path using Go with AWS CDK
