Part of the +working group’s charter is to define what Kubernetes native constructs are +required to achieve these goals. + +The Data Protection Working Group is organized with the goal of providing +a cross SIG forum to discuss how to support data protection in Kubernetes, +identify missing functionality, and work together to design features that +are needed to achieve the goal. + +### In scope + +* High level discussions on what it means to support data protection in Kubernetes at different levels and how to do it. +* Design discussions on specific topics related to data protection and disaster recovery support. +* Document results of discussions and investigations in a linkable medium. + +Potential design topics include, but are not limited to the following: +* Read data from a snapshot without creating a new volume. +* Volume backups +* Data populator +* Retrieve diffs between two snapshots (block and file level) +* Consistency volume groups (group snapshot) +* Application snapshot, backup, and recovery +* Data protection policy (Data protection policy usually means we can set up a schedule to do + periodic backups, set a backup retention policy to automatically clean up old backups, set a + topology to specify a backup location, etc. It can also possibly include policies such as + `backups must be encrypted` and `secrets must be encrypted at rest and in transit`.) +* Data protection workflows + +### Out of Scope + +* Design discussions not related to data protection is out of scope. For example, + how to migrate in-tree drivers to CSI drivers and how to report volume health + belong to SIG Storage and would not be a focus area of this WG. Workload API designs + for StatefulSet and Deployment belong to SIG Apps, however, this WG would be interested + in figuring out how to backup and recover a StatefulSet or Deployment. +* This is a working group so it does not own code. Design discussions for + a specific feature including KEP reviews can happen in the working group + but KEP approvals and code implementation will be owned by SIG-Apps or + SIG-Storage. + + +## Stakeholders + +Stakeholders for this working group include members in the following SIGs: +* SIG Apps +* SIG Storage + +We will also consult SIG Auth from security aspect. Stakeholders also include +backup vendors who want to provide data protection support in Kubernetes and +end users who want to use data protection applications. + + +## Disband criteria + +This WG will be producing documents as described in the `In Scope` section. If stakeholder SIGs and the WG decide all documents described in the `In Scope` section are complete and no more discussions and investigations are needed in this WG, they may determine to disband this WG. + + +[sig-governance]: https://github.com/kubernetes/community/blob/master/committee-steering/governance/sig-governance.md +[wg-governance]: https://github.com/kubernetes/community/blob/master/committee-steering/governance/wg-governance.md +[Kubernetes Charter README]: https://github.com/kubernetes/community/blob/master/committee-steering/governance/README.md +[lazy consensus]: http://en.osswiki.info/concepts/lazy_consensus + +[kubernetes-dev@]: https://groups.google.com/forum/#!forum/kubernetes-dev +[wg-data-protection@]: https://groups.google.com/forum/#!forum/kubernetes-wg-data-protection +[kubernetes/k8s.io]: https://git.k8s.io/k8s.io |
