Platform versions
Amazon EKS platform versions represent the capabilities of the cluster control plane, such as which Kubernetes API server flags are enabled, as well as the current Kubernetes patch version. Each Kubernetes minor version has one or more associated Amazon EKS platform versions. The platform versions for different Kubernetes minor versions are independent.
When a new Kubernetes minor version is available in Amazon EKS, such as
1.17, the initial Amazon EKS platform version for that Kubernetes minor
version starts at eks.1. However, Amazon EKS releases new platform versions
periodically to enable new Kubernetes control plane settings and to provide security
fixes.
When new Amazon EKS platform versions become available for a minor version:
-
The Amazon EKS platform version number is incremented (
eks.).n+1 -
Amazon EKS automatically upgrades all existing clusters to the latest Amazon EKS platform version for their corresponding Kubernetes minor version.
-
Amazon EKS might publish a new worker AMI with a corresponding patch version. However, all patch versions are compatible between the EKS control plane and worker AMIs for a given Kubernetes minor version.
New Amazon EKS platform versions don't introduce breaking changes or cause service interruptions.
Automatic upgrades of existing Amazon EKS platform versions are rolled out incrementally. The roll-out process might take some time. If you need the latest Amazon EKS platform version features immediately, you should create a new Amazon EKS cluster.
Clusters are always created with the latest available Amazon EKS platform version
(eks.) for the specified Kubernetes
version. If you update your cluster to a new Kubernetes minor version, your cluster
receives
the current Amazon EKS platform version for the Kubernetes minor version that you
updated
to.
