v0.9.0

Highlights:

• Ark now has support for backing up and restoring Kubernetes volumes using a free open-source backup tool called restic. This provides users an out-of-the-box solution for backing up and restoring almost any type of Kubernetes volume whether or not it has snapshot support integrated with Ark. For more information, see the documentation.
• Support for Prometheus metrics has been added! View total number of backup attempts (including success or failure), total backup size in bytes, and backup durations. More metrics coming in future releases!

All New Features:

• Add restic support (#508 #532 #533 #534 #535 #537 #540 #541 #545 #546 #547 #548 #555 #557 #561 #563 #569 #570 #571 #606 #608 #610 #621 #631 #636, @skriss)
• Add prometheus metrics (#531 #551 #564, @ashish-amarnath @nrb)
• When backing up a service account, include cluster roles/cluster role bindings that reference it (#470, @skriss)

v0.8.0

Highlights:

• Backup deletion has been completely revamped to make it simpler and less error-prone. As a user, you still use the ark backup delete command to request deletion of a backup and its associated cloud resources; behind the scenes, we've switched to using a new DeleteBackupRequest Custom Resource and associated controller for processing deletion requests.
• We've reduced the number of required fields in the Ark config. For Azure, location is no longer required, and for GCP, project is not needed.
• Ark now copies tags from volumes to snapshots during backup, and from snapshots to new volumes during restore.

Breaking Changes:

• Ark has moved back to a single namespace (heptio-ark by default) as part of #383.

All New Features:

• Add global --kubecontext flag to Ark CLI (#296, @blakebarnett)
• Azure: support cross-resource group restores of volumes (#356 #378, @skriss)
• AWS/Azure/GCP: copy tags from volumes to snapshots, and from snapshots to volumes (#341, @skriss)
• Replace finalizer for backup deletion with DeleteBackupRequest custom resource & controller (#383 #431, @ncdc @nrb)
• Don't log warnings during restore if an identical object already exists in the cluster (#405, @nrb)
• Add bash & zsh completion support (#384, @containscafeine)

Bug Fixes / Other Changes:

• Error from the Ark CLI if attempting to restore a non-existent backup (#302, @ncdc)
• Enable running the Ark server locally for development purposes (#334, @ncdc)
• Add examples to ark schedule create documentation (#331, @lypht)
• GCP: Remove project requirement from Ark config (#345, @skriss)
• Add --from-backup flag to ark restore create and allow custom restore names (#342 #409, @skriss)

• Azure: reduce API polling interval from 60s to 5s (#359, @skriss)
• Switch from hostPath to emptyDir volume type for minio example (#386, @containscafeine)
• Add limit ranges as a prioritized resource for restores (#392, @containscafeine)

Upgrading from v0.7.1:

Ark v0.7.1 moved the Ark server deployment into a separate namespace, heptio-ark-server. As of v0.8.0 we've returned to a single namespace, heptio-ark, for all Ark-related resources. If you're currently running v0.7.1, here are the steps you can take to upgrade:

1. Execute the steps from the Credentials and configuration section for your cloud:

   • AWS
   • Azure
   • GCP

   When you get to the secret creation step, if you don't have your credentials-ark file handy,
   you can copy the existing secret from your heptio-ark-server namespace into the heptio-ark namespace:

   kubectl get secret/cloud-credentials -n heptio-ark-server --export -o json | \
     jq '.metadata.namespace="heptio-ark"' | \
     kubectl apply -f -

2. You can now safely delete the heptio-ark-server namespace:

   kubectl delete namespace heptio-ark-server

3. Execute the commands from the Start the server section for your cloud:

   • AWS
   • Azure
   • GCP

v0.7.1

Bug fixed:

• Install the Ark server in its own namespace, separate from backups/schedules/restores/config. This helps avoid the situation where it's impossible to delete the heptio-ark namespace and/or backups in that namespace. (#322 #323, @ncdc @Bradamant3)
