๐ง Amazon EKS and EKS Distro now support the latest Kubernetes 1.33 release!
The Kubernetes ecosystem just got a solid upgrade โ and now Amazon EKS and Amazon EKS Distro are ready for it.
AWS has announced general availability of Kubernetes version 1.33 for both:
- Amazon Elastic Kubernetes Service (EKS)
- Amazon EKS Distro (EKS-D)
Starting today, you can:
๐ Create new EKS clusters with Kubernetes 1.33
๐ Upgrade existing clusters using the EKS console, eksctl, or your favorite IaC tool
๐ Whatโs New in Kubernetes 1.33?
Kubernetes 1.33 packs a number of improvements focused on scalability, observability, and developer flexibility.
๐งฑ 1. Stable Support for Sidecar Containers
Finally! Sidecars (e.g., for logging, security, or service mesh) are now officially stable. This unlocks better lifecycle management and more reliable injection patterns.
๐ก 2. Topology-Aware Routing and Distribution
Improved support for routing traffic based on node topology (region, zone, rack) โ reducing latency and improving availability across zones.
๐งฎ 3. Pod Topology Spread Constraints + Taints/Tolerations
Kubernetes can now consider taints and tolerations when calculating pod distribution. This means smarter scheduling decisions across your clusters.
๐ 4. User Namespaces for Linux Pods
This brings enhanced security and isolation by allowing pods to use different user ID mappings within the host system.
๐ถ 5. Dynamic Resource Allocation for Network Interfaces
Pods can now request and be assigned network resources dynamically โ great for high-performance workloads like eBPF or service meshes.
๐ 6. In-Place Pod Resource Resizing
No more restarting pods to change CPU/memory limits! You can now scale vertically with minimal disruption.
๐ ๏ธ How to Upgrade to 1.33
You can upgrade your EKS clusters to 1.33 via:
- EKS Console
- eksctl
- Terraform, CloudFormation, or CDK
Be sure to check compatibility with your workloads and custom controllers before upgrading.
๐ Regional Availability
Kubernetes 1.33 is now available in all AWS Regions where Amazon EKS is supported.
