v1.0.0

Highlights

  • We've added a new command, velero install, to make it easier to get up and running with Velero. This CLI command replaces the static YAML installation files that were previously part of release tarballs. See the updated install instructions for more information.
  • We've made a number of improvements to the plugin framework:
    • we've reorganized the relevant packages to minimize the import surface for plugin authors
    • all plugins are now wrapped in panic handlers that will report information on panics back to Velero
    • Velero's --log-level flag is now passed to plugin implementations
    • Errors logged within plugins are now annotated with the file/line of where the error occurred
    • Restore item actions can now optionally return a list of additional related items that should be restored
    • Restore item actions can now indicate that an item should not be restored
  • For Azure installation, the cloud-credentials secret can now be created from a file containing a list of environment variables. Note that velero install always uses this method of providing credentials for Azure. For more details, see Run on Azure.
  • We've added a new phase, PartiallyFailed, for both backups and restores. This new phase is used for backups/restores that successfully process some but not all of their items.
  • We removed all legacy Ark references, including API types, prometheus metrics, restic & hook annotations, etc.
  • The restic integration remains a beta feature. Please continue to try it out and provide feedback, and we'll be working over the next couple of releases to bring it to GA.

Breaking Changes

API

  • All legacy Ark data types and pre-1.0 compatibility code has been removed. Users should migrate any backups created pre-v0.11.0 with the velero migrate-backups command, available in v0.11.1.

Image

  • The base container image has been switched to ubuntu:bionic

Labels/Annotations/Metrics

  • The "ark" annotations for specifying hooks are no longer supported, and have been replaced with "velero"-based equivalents.
  • The "ark" annotation for specifying restic backups is no longer supported, and has been replaced with a "velero"-based equivalent.
  • The "ark" prometheus metrics no longer exist, and have been replaced with "velero"-based equivalents.

Plugin Development

  • BlockStore plugins are now named VolumeSnapshotter plugins
  • Plugin APIs have moved to reduce the import surface:
    • Plugin gRPC servers live in github.com/heptio/velero/pkg/plugin/framework
    • Plugin interface types live in github.com/heptio/velero/pkg/plugin/velero
  • RestoreItemAction interface now takes the original item from the backup as a parameter
  • RestoreItemAction plugins can now return additional items to restore
  • RestoreItemAction plugins can now skip restoring an item
  • Plugins may now send stack traces with errors to the Velero server, so that the errors may be put into the server log
  • Plugins must now be "namespaced," using example.domain.com/plugin-name format
    • For external ObjectStore and VolumeSnapshotter plugins. this name will also be the provider name in BackupStorageLoction and VolumeSnapshotLocation objects
  • --log-level flag is now passed to all plugins

Validation

  • Configs for Azure, AWS, and GCP are now checked for invalid or extra keys, and the server is halted if any are found
