Checkpoint/Restore In Userspace (CRIU), is a software tool for the Linux operating system.
The distinctive feature of the CRIU project is that it is mainly implemented in user space, rather than in the kernel.
However, CRIU, the current approach to snapshot/restore containers, suffers from expensive filesystem write/read operations on image files containing memory pages, which dominate the runtime costs and impact the potential benefits of manipulating in-memory process state.
We evaluate an automated, snapshot-consistent pod migration pipeline coordinating CRIU (v4.3), the Kubelet Checkpoint API (KEP-2008), Buildah OCI packaging, CRI-O (v1.31), and Cilium eBPF routing across AWS EC2 nodes.
