|
|
</operations/kata_container>`

|
|

|
|
Containers.
|
|

|
|
|
|
* Upversion OpenStack services
|
|

|
|
|
|
Back up and restore is now available for workloads running in
|
|
Kubernetes pods.
|

Guide: :doc:`Backup and restore your deployment </developer_resources/backup_restore>`
|
|
|
|

|
|
release.
