Announcing Support for Kubernetes v1.33

We are pleased to announce that Avisi Cloud now supports Kubernetes v1.33, codenamed "Octarine." This version is now available for both new and existing clusters through the Console. We recommend all users upgrade to benefit from the latest improvements and capabilities.

Please see our documentation on how to upgrade your cluster.

Key New Features

  1. Sidecar Containers Graduate to Stable Sidecar containers are no longer an alpha or beta feature—they’re fully stable. You can now rely on Kubernetes to manage auxiliary containers (logging agents, proxies, etc.) alongside your main application without worrying about unexpected API changes. This solidifies sidecars as a first-class integration pattern for extending pod functionality.

  2. In-place Resource Resize for Vertical Scaling of Pods You can now adjust CPU and memory limits on running pods without restarting them. This in-place resize capability makes vertical scaling far more responsive and less disruptive, especially for stateful workloads that can’t tolerate pod churn. In a managed service, this means smarter autoscaling with minimal downtime.

  3. Support for Mounting Images as Volumes Kubernetes 1.33 lets you mount container images directly as read-only volumes, eliminating the need for init containers to unpack artifacts. This accelerates startup for image-heavy workloads, cuts storage overhead, and simplifies delivery of static assets like web content or ML models bundled in an image.

  4. User Namespaces for Pods With user namespaces, pods can now map container root to an unprivileged host user ID, greatly improving security isolation. This feature raises the bar for multi-tenant environments by reducing the blast radius of container escapes—essential for any managed Kubernetes offering aiming at strict compliance and tenant separation.

  5. Topology-Aware Routing Pods and services can now automatically respect node, zone, or region topology when routing traffic. Instead of round-robin across the entire cluster, requests can favor local endpoints, reducing latency and cross-AZ charges. For geo-distributed clusters, it’s a must-have for cost-efficient and performant traffic management.
