Introducing Stash v2022.03.29

We are very excited to announce Stash v2022.03.29. In this release, we have made a bunch of enhancements and improvements for Stash. You can find the complete changelog here . We are going to highlight the major changes in this post.

New Features

Here, we are going to highlight the new features that have been introduced in this release.

Support templating in hooks

Stash now supports templating in backup and restore hooks. This is particularly useful when you want to send different messages in Slack notifications based on backup/restore status.

You can check the hook templating in action in this video .

Support credential-less backup

We have added support for credential-less backup in this release. Now, you can use your vendor-provided authentication mechanism for Kubernetes like GKE workload identity, AWS IRSA or kube2iam, etc. with Stash.

We have introduced two new fields named spec.runtimesettings.serviceAccountAnnotations , and spec.runtimesettings.podAnnotations to support this feature. Stash can upload its backup data or download the data from the backend using these Annotations. You need to use these Annotations in BackupConfiguration or RestoreSession to get the backup/restore done. Restic password is still required in your Secret to take backup or restore using Stash. However, you can use the secret keys in the Secret like our old method as well. Both of the authentication methods are now supported in Stash.

Better Auto-backup Experience

You can now keep your Repository and storage Secret separate from the application namespaces. This lets you configure a backup policy for your users without exposing their storage credentials to them. For more details, please check the auto-backup documentation from here .

Bug Fixes and Improvements

We have refactored our implementations in this release for better maintainability and resiliency. Also, we have fixed some bugs and upgraded our documentation.

Bug fixes

  • Fixed an RBAC issue of Restore init container
