Changelog

Sourced from kubernetes's changelog.

v21.7.0

Kubernetes API Version: v1.21.7

Bug or Regression

• Fixed kubernetes-client/python#741, an issue which prevented Kubernetes cluster api-tokens from exec-plugin auth providers from being refreshed after expiry. (#250, @​emenendez)
• Use select.poll() for exec on linux/darwin to improve scalability of WSClient (#268, @​jsun-splunk)

v21.7.0b1

Kubernetes API Version: v1.21.7

v21.7.0a1

Kubernetes API Version: v1.21.7

API Change

• Kube-apiserver: Fixes handling of CRD schemas containing literal null values in enums (#104989, @​liggitt) [SIG API Machinery, Apps and Network]
• "Auto" is now a valid value for the service.kubernetes.io/topology-aware-hints annotation. (kubernetes/kubernetes#100728, @​robscott) [SIG Apps, Instrumentation and Network]
• We have added a new Priority & Fairness rule that exempts all probes (/readyz, /healthz, /livez) to prevent restarting of "healthy" kube-apiserver instance(s) by kubelet. (kubernetes/kubernetes#101111, @​tkashem) [SIG API Machinery]
• 1. PodAffinityTerm includes a namespaceSelector field to allow selecting eligible namespaces based on their labels.
  2. A new CrossNamespacePodAffinity quota scope API that allows restricting which namespaces allowed to use PodAffinityTerm with corss-namespace reference via namespaceSelector or namespaces fields. (kubernetes/kubernetes#98582, @​ahg-g) [SIG API Machinery, Apps, Auth and Testing]
• Add Probe-level terminationGracePeriodSeconds field (kubernetes/kubernetes#99375, @​ehashman) [SIG API Machinery, Apps, Node and Testing]
• Added .spec.completionMode field to Job, with accepted values NonIndexed (default) and Indexed. This is an alpha field and is only honored by servers with the IndexedJob feature gate enabled. (kubernetes/kubernetes#98441, @​alculquicondor) [SIG Apps and CLI]
• Adds support for endPort field in NetworkPolicy (kubernetes/kubernetes#97058, @​rikatz) [SIG Apps and Network]
• CSIServiceAccountToken graduates to Beta and enabled by default. (kubernetes/kubernetes#99298, @​zshihang)
• Cluster admins can now turn off /debug/pprof and /debug/flags/v endpoint in kubelet by setting enableProfilingHandler and enableDebugFlagsHandler to false in the Kubelet configuration file. Options enableProfilingHandler and enableDebugFlagsHandler can be set to true only when enableDebuggingHandlers is also set to true. (kubernetes/kubernetes#98458, @​SaranBalaji90)
• DaemonSets accept a MaxSurge integer or percent on their rolling update strategy that will launch the updated pod on nodes and wait for those pods to go ready before marking the old out-of-date pods as deleted. This allows workloads to avoid downtime during upgrades when deployed using DaemonSets. This feature is alpha and is behind the DaemonSetUpdateSurge feature gate. (kubernetes/kubernetes#96441, @​smarterclayton) [SIG Apps and Testing]
• Enable SPDY pings to keep connections alive, so that kubectl exec and kubectl portforward won't be interrupted. (kubernetes/kubernetes#97083, @​knight42) [SIG API Machinery and CLI]
• FieldManager no longer owns fields that get reset before the object is persisted (e.g. "status wiping"). (kubernetes/kubernetes#99661, @​kevindelgado) [SIG API Machinery, Auth and Testing]
• Fixes server-side apply for APIService resources. (kubernetes/kubernetes#98576, @​kevindelgado)
• Generic ephemeral volumes are beta. (kubernetes/kubernetes#99643, @​pohly) [SIG API Machinery, Apps, Auth, CLI, Node, Storage and Testing]
• Hugepages request values are limited to integer multiples of the page size. (kubernetes/kubernetes#98515, @​lala123912) [SIG Apps]
• Implement the GetAvailableResources in the podresources API. (kubernetes/kubernetes#95734, @​fromanirh) [SIG Instrumentation, Node and Testing]
• IngressClass resource can now reference a resource in a specific namespace for implementation-specific configuration (previously only Cluster-level resources were allowed). This feature can be enabled using the IngressClassNamespacedParams feature gate. (kubernetes/kubernetes#99275, @​hbagdi)
• Jobs API has a new .spec.suspend field that can be used to suspend and resume Jobs. This is an alpha field which is only honored by servers with the SuspendJob feature gate enabled. (kubernetes/kubernetes#98727, @​adtac)
• Kubelet Graceful Node Shutdown feature graduates to Beta and enabled by default. (kubernetes/kubernetes#99735, @​bobbypage)
• Kubernetes is now built using go1.15.7 (kubernetes/kubernetes#98363, @​cpanato) [SIG Cloud Provider, Instrumentation, Node, Release and Testing]
• Namespace API objects now have a kubernetes.io/metadata.name label matching their metadata.name field to allow selecting any namespace by its name using a label selector. (kubernetes/kubernetes#96968, @​jayunit100) [SIG API Machinery, Apps, Cloud Provider, Storage and Testing]
• One new field "InternalTrafficPolicy" in Service is added. It specifies if the cluster internal traffic should be routed to all endpoints or node-local endpoints only. "Cluster" routes internal traffic to a Service to all endpoints. "Local" routes traffic to node-local endpoints only, and traffic is dropped if no node-local endpoints are ready. The default value is "Cluster". (kubernetes/kubernetes#96600, @​maplain) [SIG API Machinery, Apps and Network]
• PodDisruptionBudget API objects can now contain conditions in status. (kubernetes/kubernetes#98127, @​mortent) [SIG API Machinery, Apps, Auth, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]
• PodSecurityPolicy only stores "generic" as allowed volume type if the GenericEphemeralVolume feature gate is enabled (kubernetes/kubernetes#98918, @​pohly) [SIG Auth and Security]
