Key Points
Highlight key points with color coding based on sentiment (positive, neutral, negative).Kubernetes v1.35 introduces in-place updates for Pod resources, allowing CPU and memory adjustments without restarting Pods, which enhances efficiency and reduces disruption for stateful or batch applications.
The release includes native workload identity with automated certificate rotation to simplify service mesh and zero-trust architectures by eliminating the need for external controllers and manual certificate management.
The theme of the World Tree symbolizes the growth and community-driven development of Kubernetes, with three guardian squirrels representing key roles in the release process: reviewers, release crews, and issue triagers.
Kubernetes v1.35 enhances security by enforcing credential verification for cached images: Only authorized workloads can use private images, even if they are already present on the node.
The release deprecates the ipvs mode in kube-proxy and encourages a transition to nftables for improved performance and maintainability, and marks the final call for containerd v1.X support, urging a switch to containerd 2.0 or later.
Kubernetes v1.35, known as the Timbernetes or World Tree Release, introduces 60 improvements. Among these, 17 features have reached stable status, 19 are in beta, and 22 are in alpha. The release includes the stable release of in-place Pod resource updates, which permits CPU and memory adjustments without restarting Pods or Containers.
Kubernetes v1.35 also introduces beta features such as native workload identity and automated certificate rotation. The kubelet can now generate keys, request certificates via PodCertificateRequest, and write credential bundles directly to the Pod's filesystem. This update enforces node restrictions at admission time.
Additional features include the PreferSameNode traffic distribution option, which prioritizes endpoints on the local node, and the Job API managed-by mechanism, allowing external controllers to handle Job status synchronization.
The release theme, inspired by Yggdrasil, the tree of life, highlights the global community's contribution to Kubernetes. The theme includes three guardian squirrels representing different community roles: a wizard for reviewers, a warrior for release crews, and a rogue for triagers.
Kubernetes v1.35 addresses several deprecations and removals. The Ingress NGINX controller is being retired, and cgroup v1 support is being phased out. Users are advised to migrate to the Gateway API for traffic management and make sure their nodes support cgroup v2. Kubernetes v1.35 is available for download.
