Changelog

v0.6.0 - 2017-11-30

Highlights:

  • Plugins - We now support user-defined plugins that can extend Ark functionality to meet your custom backup/restore needs without needing to be compiled into the core binary. We support pluggable block and object stores as well as per-item backup and restore actions that can execute arbitrary logic, including modifying the items being backed up or restored. For more information see the documentation, which includes a reference to a fully-functional sample plugin repository. (#174 #188 #206 #213 #215 #217 #223 #226)
  • Describers - The Ark CLI now includes describe commands for backups, restores, and schedules that provide human-friendly representations of the relevant API objects.

Breaking Changes:

  • The config object format has changed. In order to upgrade to v0.6.0, the config object will have to be updated to match the new format. See the examples and documentation for more information.
  • The restore object format has changed. The warnings and errors fields are now ints containing the counts, while full warnings and errors are now stored in the object store instead of etcd. Restore objects created prior to v.0.6.0 should be deleted, or a new bucket used, and the old restore objects deleted from Kubernetes (kubectl -n heptio-ark delete restore --all).

All New Features:

  • Add ark plugin add and ark plugin remove commands #217, @skriss
  • Add plugin support for block/object stores, backup/restore item actions #174 #188 #206 #213 #215 #223 #226, @skriss @ncdc
  • Improve Azure deployment instructions #216, @ncdc
  • Change default TTL for backups to 30 days #204, @nrb
  • Improve logging for backups and restores #199, @ncdc
  • Add ark backup describe, ark schedule describe #196, @ncdc
  • Add ark restore describe and move restore warnings/errors to object storage #173 #201 #202, @ncdc
  • Upgrade to client-go v5.0.1, kubernetes v1.8.2 #157, @ncdc
  • Add Travis CI support #165 #166, @ncdc

Bug Fixes:

  • Fix log location hook prefix stripping #222, @ncdc
  • When running ark backup download, remove file if there's an error #154, @ncdc
  • Update documentation for AWS KMS Key alias support #163, @lli-hiya
  • Remove clock from volume_snapshot_action #137, @athampy

v0.5.1 - 2017-11-06

Bug fixes:

  • If a Service is headless, retain ClusterIP = None when backing up and restoring.
  • Use the specifed --label-selector when listing backups, schedules, and restores.
  • Restore namespace mapping functionality that was accidentally broken in 0.5.0.
  • Always include namespaces in the backup, regardless of the --include-cluster-resources setting.

v0.5.0 - 2017-10-26

Breaking changes:

  • The backup tar file format has changed. Backups created using previous versions of Ark cannot be restored using v0.5.0.
  • When backing up one or more specific namespaces, cluster-scoped resources are no longer backed up by default, with the exception of PVs that are used within the target namespace(s). Cluster-scoped resources can still be included by explicitly specifying --include-cluster-resources.

New features:

  • Add customized user-agent string for Ark CLI
  • Switch from glog to logrus
  • Exclude nodes from restoration
  • Add a FAQ
  • Record PV availability zone and use it when restoring volumes from snapshots
  • Back up the PV associated with a PVC
  • Add --include-cluster-resources flag to ark backup create
  • Add --include-cluster-resources flag to ark restore create
  • Properly support resource restore priorities across cluster-scoped and namespace-scoped resources
  • Support ark create ... and ark get ...
  • Make ark run as cluster-admin
  • Add pod exec backup hooks
  • Support cross-compilation & upgrade to go 1.9

Bug fixes:

  • Make config change detection more robust

v0.4.0 - 2017-09-14

Breaking changes:

  • Snapshotting and restoring volumes is now enabled by default
  • The --namespaces flag for 'ark restore create' has been replaced by --include-namespaces and --exclude-namespaces

New features:

  • Support for S3 SSE with KMS
  • Cloud provider configurations are validated at startup
  • The persistentVolumeProvider is now optional
  • Restore objects are garbage collected
  • Each backup now has an associated log file, viewable via 'ark backup logs'
  • Each restore now has an associated log file, viewable via 'ark restore logs'
  • Add --include-resources/--exclude-resources for restores

Bug fixes:

  • Only save/use iops for io1 volumes on AWS
  • When restoring, try to retrieve the Backup directly from object storage if it's not found
  • When syncing Backups from object storage to Kubernetes, don't return at the first error encountered
  • More closely match how kubectl performs kubeconfig resolution
  • Increase default Azure API request timeout to 2 minutes
  • Update Azure diskURI to match diskName
