Kubernetes Blog ☛ Fresh Swap Features for GNU/Linux Users in Kubernetes 1.32
Swap is a fundamental and an invaluable GNU/Linux feature. It offers numerous benefits, such as effectively increasing a node’s memory by swapping out unused data, shielding nodes from system-level memory spikes, preventing Pods from crashing when they hit their memory limits, and much more. As a result, the node special interest group within the Kubernetes project has invested significant effort into supporting swap on GNU/Linux nodes.
The 1.22 release introduced Alpha support for configuring swap memory usage for Kubernetes workloads running on GNU/Linux on a per-node basis. Later, in release 1.28, support for swap on GNU/Linux nodes has graduated to Beta, along with many new improvements. In the following Kubernetes releases more improvements were made, paving the way to GA in the near future.
