Feature Stage

In Kube-OVN, feature stage is classified into Alpha, Beta and GA, based on the degree of feature usage, documentation and test coverage.

Definition of Stage

For Alpha stage functions:

  • The feature is not fully documented and well tested.
  • This feature may change or even be removed in the future.
  • This feature API is not guaranteed to be stable and may be removed.
  • Community provides low priority support for this feature and long-term support cannot be guaranteed.
  • Since feature stability and long-term support cannot be guaranteed, it can be tested and verified, but is not recommended for production use.

For Beta stage functions:

  • This feature is partially documented and tested, but complete coverage is not guaranteed.
  • This feature may change in the future and the upgrade may affect the network, but it will not be removed as a whole.
  • This feature API may change in the future and the fields may be adjusted, but not removed as a whole.
  • This feature will be supported by the community in the long term.
  • It can be used on non-critical services as the functionality will be supported for a long time, but it is not recommended for critical production service as there is a possibility of changes in functionality and APIs that may break the network.

For GA stage functions:

  • The feature has full documentation and test coverage.
  • The feature will remain stable and upgrades will be guaranteed to be smooth.
  • This feature API is not subject to disruptive changes.
  • This feature will be supported with high priority by the community and long-term support will be guaranteed.
