🔧 Amazon EKS and EKS Distro now support the latest Kubernetes 1.33 release!
The Kubernetes ecosystem just got a solid upgrade — 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:
🚀 Create new EKS clusters with Kubernetes 1.33
🔄 Upgrade existing clusters using the EKS console, eksctl, or your favorite IaC tool
🔍 What’s New in Kubernetes 1.33?
Kubernetes 1.33 packs a number of improvements focused on scalability, observability, and developer flexibility.
🧱 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.
📡 2. Topology-Aware Routing and Distribution
Improved support for routing traffic based on node topology (region, zone, rack) — reducing latency and improving availability across zones.
🧮 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.
🔐 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.
📶 5. Dynamic Resource Allocation for Network Interfaces
Pods can now request and be assigned network resources dynamically — great for high-performance workloads like eBPF or service meshes.
📈 6. In-Place Pod Resource Resizing
No more restarting pods to change CPU/memory limits! You can now scale vertically with minimal disruption.
🛠️ 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.
🌍 Regional Availability
Kubernetes 1.33 is now available in all AWS Regions where Amazon EKS is supported.
