OpenEBS - v3.3.0


Release Summary

🎉 🎉 🎉 OpenEBS 3.3 is another maintenance release focused on code, tests and build refactoring along with some critical bug fixes and user enhancements. This release includes fixes for user-reported critical bugs as well as fixes and enhancements to improve the E2e test coverage.

Deprecation Notice: Jiva and cStor out-of-tree external provisioners are deprecated now in favor of the corresponding CSI Drivers. The out of tree provisioners for Jiva and cStor will stop working from Kubernetes 1.22 and forward as the version of the custom resources used by those provisioners will be deprecated. We strongly recommend you plan for migrating your volumes to cStor CSI or Jiva CSI as early as possible.

If you have any questions or need help with the migration please reach out to us on our Kubernetes Community slack channel #openebs.

Upgrade and Backward Incompatibilities

Please review this list prior to deciding to upgrade:

  • Kubernetes 1.18 or higher release is recommended as this release uses features of Kubernetes that will not be compatible with older Kubernetes releases. Some of the engines might require you to have a higher Kubernetes version as the CSI drivers have been upgraded to the latest versions. For example, Kubernetes 1.19.12 or higher is recommended for using Rawfile Local PV.
  • OpenEBS has deprecated arch-specific container images in favor of multi-arch container images. For example, images like cstor-pool-arm64:x.y.x should be replaced with corresponding multi-arch image cstor-pool:x.y.x.
  • The non-csi provisioners for cstor and jiva are not included by default with 3.0 helm chart or operator.yaml. You can still continue to use them. The older provisioners are released with the v2.12.2 version at the moment and only patch releases (to fix severe security vulnerabilities) will be supported going forward. If you need help making a decision on upgrading or migrating, please reach out to us on our Kubernetes Community slack channel #openebs.
