Kubernetes v1.36: Mutable Pod Resources for Suspended Jobs (beta)
Kubernetes v1.36 promotes the ability to modify container resource requests and limits in the pod template of a suspended Job to beta. First introduced as alpha in v1.35, this feature allows queue controllers and cluster administrators to adjust CPU, memory, GPU, and extended resource specifications on a Job while it is suspended, before it starts or resumes running. Why mutable pod resources for suspended Jobs?Batch and machine learning workloads often have resource requirements that are not precisely known at Job creation time. The optimal resource allocation depends on current cluster capacity, queue priorities, and the availability of specialized hardware like GPUs. Before this feature, resource requirements in a Job's pod template were immutable once set. If a queue controller like Ku
