Epic Goal
- Graduate swap to Beta in upstream Kubernetes. The general steps are:
- Make sure cgroups v2 fully supports limiting swap on a per-container basis
- Design a container-level swap configuration API for Kubernetes
- Implement new changes for CRIO, who would configure the cgroups correctly
- See if there are more requirements to move swap into Beta.
Why is this important?
- Swap support is one of CNV's goals for CY23
- CNV cannot productize any alpha features since they're unstable and can be removed at any moment. Therefore, swap needs to graduate to Beta in upstream Kubernetes
- In addition, many swap features don't currently work with cgroups v2. Therefore we need to implement them for both CRIO and Kubernetes.
