perfkitbenchmarker/linux_benchmarks/kubernetes/agentic/k8s_snapshot_benchmark.pyDescription: Adds the GKE Pod Snapshot saturation benchmark:
Pod Snapshot: Measures GKE Pod Snapshot create/restore latency under varying memory preload sizes. Creates source pods with configurable memory footprints, triggers CRIU checkpoints to GCS-backed storage, restores from snapshots, and measures TTFE (Time To First Execution) for restored pods. Includes:
--skip_snapshotmode for cold-start TTFE measurement (no snapshot/restore)--preload_mode=script:<path>for custom startup scripts (vibe coding simulation)DeploySnapshots()integration for GCS bucket, managed folder, KSA, and IAM setupThis is the only benchmark that uses GKE Pod Snapshots (CRIU + GCS), PodSnapshotManualTrigger CRDs, and creates its own SandboxTemplates per measurement (rather than using the shared warm pool).
