v0.6.0

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

A few bugs squeaked their way in to v0.5.0. This release hopefully squashes them!

Bugs fixed:

• Headless services were incorrectly restored as cluster-ip services (backport of #171, @nrb)
• Label selectors were not being honored when listing backups, schedules, and restores (backport of #169, @nrb)
• Restore namespace mappings were inadvertently broken (backport of #179, @skriss)
• Namespace objects were not always included in the backup (backport of #182, @dgoodwin and @ncdc)
• Namespace objects that should have been excluded were incorrectly included (backport of #182, @dgoodwin and @ncdc)

v0.5.0

Highlights:

• Backup hooks - users can now specify that custom scripts within their containers should be executed during Pod backups. This is particularly useful for stateful workloads where disk buffers need to be flushed, database commands need to be issued, etc. (#112)
• Multi-AZ cluster support - we now support backups including PV snapshots for clusters spanning multiple AZs. Ark no longer expects an AZ to be specified in the config; the AZ for each PV will be recorded during backup execution and used for subsequent restores. (#102)
• Easier backups of individual namespaces - it's now possible to backup one or more namespaces, including any PVs used by them, without having to explicitly exclude cluster-scoped resources. Simply use: ark backup create <backup-name> --include-namespaces=<ns1,ns2,...>, and Ark will automatically exclude irrelevant cluster-scoped resources. (#65, #128, #147)
• Ark CLI binaries - Going forward, we recommend running the Ark CLI binary directly rather than in a container. We're now publishing these as part of releases. (#148)

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.

All New Features:

• Add customized user-agent string #69, @jrnt30
• Switch from glog to logrus #98 #126 #122 #123, @skriss
• Exclude nodes from restoration #99, @jrnt30
• Add a FAQ #113, @julia-stripe
• Record PV availability zone and use it when restoring #102, @ashish-amarnath
• Back up the PV associated with a PVC #65, @skriss
• Add --include-cluster-resources flag to ark backup create #128, @skriss
• Add --include-cluster-resources flag to ark restore create #147, @skriss
• Properly support resource restore priorities across cluster-scoped and namespace-scoped resources #132, @dgoodwin
• Support ark create ... and ark get ... #81, @ncdc
• Make ark run as cluster-admin #145, @skriss
• Add pod exec backup hooks #112, @ncdc
• Support cross-compilation & upgrade to go 1.9 #148, @ncdc

Bug Fixes:

• Make config change detection more robust #96, @ncdc
