Cloud Container Engine – New Kubernetes 1.19 version and migration tool
Flexible Engine
Release Notes
September, 2021
Flexible Engine’s container management service: Cloud Container Engine now supports 1.19.10 kubernetes clusters. As of today you’ll be able to create kubernetes clusters in version 1.19, or upgrade your version 1.17 clusters to 1.19 with our provided migration tool.
1.1 New Features | Feature Description and Impact | Constraints/Comments | |
1 | CCE cluster support Kubernetes version 1.19.10 | New Kubernetes version 1.19.10 | CentOS 7.6 uses kernel 3.10.0-1127.19.1.el7.x86_64. EulerOS 2.5 uses kernel 3.10.0-862.14.1.5.h470.eulerosv2r7.x86_64 |
2 | Support clusters upgrade from Kubernetes 1.17 to 1.19 |
As for previous CCE versions, CCE support cluster versions upgrade using standard “Replace upgrade” feature:
|
Data or configurations on the node will be lost, and services will be interrupted for a period of time.
|
This new version of CCE also introduce a brand new Beta upgrade mode called “in Place Rolling Upgrade”. It allows users to upgrade their clusters without any service interruption:
Advantage: Users do not need to migrate services, which ensures service continuity. |
An in-place upgrade does not upgrade the node OS. If you want to upgrade the OS, clear the node after the node upgrade is complete and reset the node to upgrade the OS to the new version.
NOTE: This feature is currently in Beta mode, if you would like to test this feature, please submit a ticket on our Service Desk. |

Support agency binding when using the API to create nodes |
|
5 | Pod security policies are enabled in the version 1.19. | By default, the PSP access control component is enabled for clusters of v1.19 and a global default PSP named psp-global is created. You can modify the default policy (but not delete it). You can also create a PSP and bind it to the RBAC configuration. | |
6 | Support OIDC authentication. | CCE supports OIDC functionality via IAM. The OIDC protocol-based Enterprise IdP is federated with the IAM for identity authentication. The detailed OIDC authentication process and configuration procedure can be found in https://docs.prod-cloud-ocb.orange-business.com/usermanual/iam/en-us_topic_0274187177.html | |
7 | Fix the coredns 1.6.5 upgrade failure. | Previous versions of CoreDNS failed to upgrade to CoreDNS 1.6.5, in this CCE version we fixes the issue. | |
8 | Console Optimization |
On the job list page can display: the job execution duration, start time, and end time CCE cronjob, support users modify YAML files in the console and it can synchronize configuration changes, and perform real-time tests. |
