I would like to request membership to help chair the new Checkpoint/Restore WG together with Viktoria Spišaková and Adrian Reber. Over the past few years, we have been working on enabling the Checkpoint/Restore functionality in Kubernetes, and after our KubeCon talk in London earlier this year, several people in the community reached out to express interest in contributing to our discussions and asked us to create a working group.
List of contributions to the Kubernetes project
Contributions within the Kubernetes orgs:
One of my direct contributions has been with the functionality to restore containers from a checkpoint. I have implemented the initial prototype of this functionality in Podman, and later we enabled this with CRI-O and containerd. This has been included in Adrian's KEP and blog post:
- Add blog post about forensic container checkpointing website#37412
- https://kubernetes.io/blog/2022/12/05/forensic-container-checkpointing-alpha/
- Forensic Container Checkpointing enhancements#2008
