The further Kubernetes version 1.15 (beta) extends the existing 1.13 and removes the old 1.11 version. The 1.15.6 version is currently being offered as a beta, as there are currently some security vulnerabilities in the specified Kubernetes version. The corresponding vulnerabilities and descriptions can be found on the following page: https://groups.google.com/forum/#!topic/kubernetes-security-announce/2UOlsba2g0s
We are already working on a solution to fix these vulnerabilities and the next version 1.17, which is expected in September.
Existing users of version 1.11 should upgrade to the next higher version 1.13 for security reasons with the integrated upgrade function. Version 1.11 is no longer available for the provision of new clusters. The corresponding upgrade function can be accessed via the action button on the cluster overview page.
Then there is a section of the features in this release.
Auto Scaling feature enhancement
Access to the management of automatic scaling policies has been simplified and summarized in a separate menu for automatic scaling in the left navigation area.
The advanced configuration of the autoscaling plugin consists of:
- Node scaling - Ability to configure metric-based (CPU / MEM usage) or planned (new) - daily, weekly, monthly, accurate date/exit rules for nodes.
- Workload Scaling (new) - Horizontal Pod Auto Scaling (HPA) - A policy that implements horizontal scaling of pods in Kubernetes. This policy adds the HPA-level cooldown window and scaling threshold features based on the HPA feature provided by the Kubernetes community. Also offers a new addon called metric-server.
Support of CSI (Container Storage Interface)
Offers a new version of the add-on Everest for memory management. Everest is a cloud-native container storage system. Based on CSI, clusters from Kubernetes v1.15.6 or higher can be connected to storage services such as EVS, OBS, and SFS. This add-on is required for the snapshot function.
Support volume snapshot
CCE works with the EVS (Elastic volume service) service to provide the snapshot function. A snapshot is a complete copy of the EVS hard disk data image at a particular point in time. Snapshots can be used to quickly recover data, migrate, or quickly deploy multiple services. May be helpful before changing operating systems or upgrading application software.
Support UCD 4.0 in CCE console
The new user interface makes the CCE console easier to use, more intuitive, and easier to manage. The dashboard provides an overview of all important information about Kubernetes clusters and their components.
Further information can be found in the CCE area of the Help Center.
