That changes with the new Kubernetes 1.19. Structured loggingĮarlier, the control plane in Kubernetes did not have a uniform structure. As a part of this enhancement, there are some key differences in V1 Ingress objects, including mapping and approval changes. In Kubernetes 1.19, Ingress is added to the systems administration V1 APIs and graduates to general accessibility. This enhancement is a step in the direction of programmatic detection to monitor volume health problems and provide a quick resolution. This information is then used to report such conditions on Pods or PVCs.
#Kubernetes ephemeral storage drivers
It allows the CSI Drivers to pass on the information to Kubernetes. This is a new alpha feature that kicks in if there is any abnormal volume condition in the underlying storage. It supports all features that were earlier supported by PersistentVolumeClaims like storage capacity tracking, volume resizing, and snapshots and restore. The new enhancement provides scratch storage and supports all StorageClass parameters for provisioning volume. It allows any of the current storage drivers that support dynamic provisioning to be used as ephemeral volume. Generic ephemeral volumes are a new alpha feature in the Kubernetes 1.19. Generic ephemeral volumesĮphemeral volumes are volumes that are created for specific pods and are deleted once the pod terminates.
#Kubernetes ephemeral storage free
This enhancement was introduced to prevent pods from being scheduled on nodes connected to CSI volumes without enough available free space. This feature gathers capacity information and then stores it in the API server, making it available to the scheduler. Storage capacity tracking is a new feature, albeit in the alpha stage, in the Kubernetes 1.19. With the extension of the support window, 80% of the users are expected to be on the supported versions instead of the current 50% to 60%. The suggestion provided was that if there were an extension of 12 to 14 months, 30% of users would be able to keep their deployments on the supported version.
#Kubernetes ephemeral storage upgrade
The decision was taken after a 2019 study revealed that a large number of end-users, for whatever reasons, could not upgrade within the current support period of 9-months.

With its Kubernetes 1.19 release, the support window has been extended to 1 year from 9 months. Here are some key features of the new Kubernetes 1.19: Support window extension Out of these, 10 have progressed to stable, 15 are in the beta stage, and 9 in the alpha. The new Kubernetes 1.19 comes with 34 enhancements. The Topology Manager feature of Kubernetes 1.18 allows NUMA alignment of the CPU and other devices that giving a great experience. The Kubernetes team has worked diligently to improve the stable and beta features ensuring a better user experience. Fifteen of these have been stabilized, 11 are in the beta testing phase while the remaining 12 are in the alpha phase. The new Kubernetes 1.19 was a bit delayed, but that was expected when the world is reeling under the global pandemicĮarlier this year, the team had released Kubernetes 1.18 which consisted of 38 enhancements. The Kubernetes team has done a commendable job by recently launching the Kubernetes version 1.19.
