Kubernetes 1.8 just out!

Kubernetes 1.8 is the third release this year including Kubernetes 1.6 and Kubernetes 1.7. With this release, I am sure Kubernetes is growing really fast with its talented community.

While Kubernetes 1.6 and Kubernetes 1.7 focused on the new features like security, RBAC, scaling, federation etc. Kubernetes 1.8 release is more focused on stability. With recent release new Role Based Access Policy support is now stable. This release also focused on process, governance model and architecture of Kubernetes.

It consists two major enhancements in security and workload support.

Security:

With K8s 1.8 RBAC support is now stable. It’s the big goal. The administrator can assign the dynamic roles with RBAC. Also, filtering is included for outbound traffic through network policies.

Automatic certificate rotation for Transport layer security included for the Kubelet which is in beta.

Workload Support:

Beta support for the workload. It introduces apps/v1beta2 API for the workload group and version.

Native support of Kubernetes in Apache Spark is introduced. So it’s possible to run Big Data workloads on Kubernetes.

CronJob is now in its beta version which will help to schedule nightly ETL jobs.

Custom Resource Definitions (CRDs) is still in beta which helps in complex automation task where developers can use user-defined API objects.

Kubernetes 1.8 is available for download on GitHub. And also Join the community at KubeCon + CloudNativeCon in Austin, December 6–8 for the largest Kubernetes gathering ever.
