Managing storages
Kubernetes storages provide a common file system to pod containers enabling them to store and exchange data. The management console allows you to manage your Kubernetes storage without using kubectl.
Creating a storage resource
You can create storage resources in the management console in the same way as when using the kubectl apply -f <manifest_file.yaml> -n <namespace_name> command.
- In the management console, navigate to the folder dashboard and select Managed Service for Kubernetes.
- Click the cluster name and select Storage in the left-hand panel.
- In the top-right corner, click Create and select the resource type.
- In the drop-down list, select the Namespace to create the resource in.
- Fill out the manifest file according to the Kubernetes guide: Persistent Volume Claim, Persistent Volume, storage class.
- Click Create.
Editing a storage resource
In the management console, you can edit storage resource manifests in a visual editor. This approach is equivalent to running the kubectl apply -f <manifest_file.yaml> command and allows you to update the resource configuration without re-creating it.
The list of editable fields depends on the object type and is available in this Kubernetes guide.
- In the management console, navigate to the folder dashboard and select Managed Service for Kubernetes.
- Click the cluster name and select Storage in the left-hand panel.
- Select the tab with the resource type you want to edit.
- In the row of the resource, click and select Edit.
- Edit the manifest file on the right side of the screen. Your changes will be highlighted with color.
- In the top-right corner, click Save.
If the manifest is correct, the changes will be applied. If the updated manifest contains an error or edits uneditable fields, an error message will appear. Click More information for details.
Setting or removing the default storage class
The default storage class is used when creating a Persistent Volume Claim, if spec.storageClassName is not specified in its manifest. You can designate multiple storage classes as default classes at the same time. In which case the last created storage class is used when creating a Persistent Volume Claim.
This approach is equivalent to running the kubectl patch storageclass <storage_class_name> -p '{"metadata":{"annotations":{"storageclass.kubernetes.io/is-default-class":"<true-or-false>"}}}' command.
To set or remove the default storage class:
- In the management console, navigate to the folder dashboard and select Managed Service for Kubernetes.
- Click the cluster name and select Storage in the left-hand panel.
- Select the Storage classes tab.
- In the storage class row, click and select Use as default or Don't use as default.
- Confirm the action.
Deleting a storage resource
Deleting a storage resource is equivalent to running the kubectl delete -f <manifest_file.yaml> command.
To delete a storage resource:
- In the management console, navigate to the folder dashboard and select Managed Service for Kubernetes.
- Click the cluster name and select Storage in the left-hand panel.
- Select the tab containing the resource type you want to delete.
- In the row of the resource, click and select Delete.
- Confirm the action.
