说明

Kubernetes每个版本特性,关注新特性的支持版本和主要组件兼容版本,主要收集文档连接,根据工作情况随时更新。

Release工作计划

Sig-Release中有每次发布的文件目录,提供了每个Release计划的Google Doc文档地址。

最近一些Release计划的任务列表,Google Doc文档,国内不能直接访问,要翻:

Kubernetes Enhancements Tracking - 1.13 Release

Kubernetes Features Tracking - 1.12 Release

Kubernetes Features OSS tracking board (1.11 release)

Kubernetes Features OSS tracking board (1.10 release)

Kubernetes Features OSS tracking board (1.9 release)

Kubernetes Features OSS tracking board (1.8 release)

                             1.11.x       1.12.x       1.13.x     1.14.x    
--------------------------------------------------------------------------
Docker                     >=1.11.x     >=1.11.x    >=1.11.x     >=1.11.x
IPVS                          GA

KubeAdm                                                GA
drop support for etcd2                                 GA
Kubelet Device Plugin                                  GA

Kubernetes Feature Gates收录的更全面, 并且有对Feature Gates的说明。

组件兼容性考虑

The minimum required Docker version will vary as the kubelet version changes. The newest stable release is a good choice. Kubelet will log a warning and refuse to start pods if the version is too old, so pick a version and try it.

Kubelet    DockerAPI   Docker
-------------------------------
1.8.15     >=1.22.0   >=1.10.x
1.9.11     >=1.22.0   >=1.10.x
1.10.12    >=1.23.0   >=1.11.x
1.11.6     >=1.23.0   >=1.11.x
1.12.4     >=1.23.0   >=1.11.x
1.13.1     >=1.23.0   >=1.11.x

参考

  1. kubenetes setup: docker
  2. kubelet: MinimumDockerAPIVersion
  3. Kubernetes 1.11: In-Cluster Load Balancing and CoreDNS Plugin Graduate to General Availability
  4. Kubernetes 1.12: Kubelet TLS Bootstrap and Azure Virtual Machine Scale Sets (VMSS) Move to General Availability
  5. Kubernetes 1.13: Simplified Cluster Management with Kubeadm, Container Storage Interface (CSI), and CoreDNS as Default DNS are Now Generally Available
