![]() In the previous versions, the Amazon EKS kubelet had a 10-requests per seconds limit for kubeAPIQPS with a burst limit of 20 requests for kubeAPIburst. Lastly, issue #3243 implements the matchLabelKeys field in the topologySpreadConstraints in the pod’s specification, which permits the selection of pods for spreading calculations following a rolling upgrade. This particular feature is linked with the NodeInclusionPolicyInPodTopologySpread gate. Issue #3094 introduces the nodeAffinityPolicy and nodeTaintPolicy parameters, which allow for an extra level of granularity in governing pod distribution according to node affinities and taints. In particular, issue #3022 unveils the minDomains parameter, giving the administrator the ability to set the minimum number of domains your pods should occupy, thereby guaranteeing a balanced spread of workloads across the cluster. This Kubernetes version has some features that allow better management of the pod topology and an easier way to spread balanced pods across various domains. The security-profiles-operator allows for defining and managing custom profiles for the workloads. When the seccomp profile is enabled, some workloads may experience breakages, but it is possible to disable or create custom profiles for specific workloads. ![]() In this way, the seccomp profile is defined by the container runtime, instead of using the unconfined (seccomp disabled) mode. Passing the –kubelet-extra-args "–seccomp-default" flag in the node bootstrap script or launch template will enable the default seccomp profile for all containers running on the node. In Kubernetes 1.27, seccomp is graduated as stable and activated by default: the RuntimeDefault seccomp profile will be used as default for all workloads. In this version of Kubernetes there are a lot of new features that are generally available and some of them are potentially destructive for the clusters. AWS announced the support of Kubernetes version 1.27, called Chill Vibes, for Amazon EKS and Amazon EKS Distro.
