Label resources
Kubernetes allows you to selectively apply required labels to the resources of a namespace with a key-value
format using the CLI. Portworx Backup UI enables you to filter those labeled resources with the label and then take a backup of all such resources of the selected namespace.
For example, consider two namespaces, ns1
and ns2
. For the sake of brevity, assume that ns1
has label x=y
and ns2
has no label. Again consider a resource called configmap1
in ns1
and configmap2
in ns2
. When you apply a resource label a=b
on configmap1
and configmap2
using the CLI, the resource label gets applied to both the resources regardless of which namespace it belongs to.
If you filter a namespace in Portworx Backup with x=y
and resource label as a=b
, only ns1
gets displayed in the list. When you create a backup of ns1
, Portworx Backup displays and fetches only conifgmap1
belonging to ns1 for the backup.
To filter and then back up the resources with preset labels:
-
Type the label name in the Add resource label field and press Enter.
-
Select the required namespace(s) and then click Backup:
noteThe label used to filter appears under the RESOURCE LABEL SELECTOR field of Create Backup window.
-
Click Create to back up only the labeled resources of the selected namespace(s).
note- If the selected namespace does not include resources with preset labels, then Portworx Backup ignores those resources for backup.
- For scheduled backup of resources, Portworx Backup checks for resources with preset labels in only those namespaces that were selected during the creation of backup.
