Installing the extension on Azure (AKS)
Before you install the NetBackup Snapshot Manager extension on a managed Kubernetes cluster (AKS) in Azure:
To install the extension
- Download the extension script
nbu_flexsnap_extension.tar.See Downloading the NetBackup Snapshot Manager extension.
Note:
Do not create the authentication token yet, as it is valid only for 180 seconds.
- If the host from which you want to install the extension is not the same host where your NetBackup Snapshot Manager is installed, load the NetBackup Snapshot Manager container images on the extension host (
flexsnap-deploy, flexsnap-core, flexsnap-fluentd, flexsnap-datamover)The image names are in the following format:
Example:
veritas/flexsnap-deploy - Create image tags to map the source image with the target image, so that you can push the images to the Azure container registry. For more information, see Prerequisites to install the extension on a managed Kubernetes cluster in Azure.
Gather the following parameters beforehand:
Parameter
Description
container_registry_path
To obtain the container registry path, go to your container registry in Azure and from the Overview pane, copy the 'Login server'.
Example:
mycontainer.azurecr.iotag
NetBackup Snapshot Manager image version.
Example:
11.1.x.x-xxxxTo tag the images, run the following command for each image, depending on the container platform running on your host:
For Docker: # docker tag source_image:tag target_image:tag
For Podman: # podman tag source_image:tag target_image:tag
Where,
the source image tag is: veritas/flexsnap-deploy:tag>
the target image tag is: <container_registry_path>/<source_image_name>:<SnapshotManager_version_tag>
Example:
# docker tag veritas/flexsnap-deploy:11.1.x.x-xxxx mycontainer.azurecr.io/veritas/flexsnap-deploy:11.1.x.x-xxxx # docker tag veritas/flexsnap-core:11.1.x.x-xxxx mycontainer.azurecr.io/veritas/flexsnap-core:11.1.x.x-xxxx # docker tag veritas/flexsnap-fluentd:11.1.x.x-xxxx mycontainer.azurecr.io/veritas/flexsnap-fluentd:11.1.x.x-xxxx # docker tag veritas/flexsnap-datamover:11.1.x.x-xxxx mycontainer.azurecr.io/veritas/flexsnap-datamover:11.1.x.x-xxxx
- Then to push the images to the container registry, run the following command for each image, depending on the container platform running on your host:
For Docker: # docker push target_image:tag
For Podman: # podman push target_image:tag
Example:
# docker push mycontainer.azurecr.io/veritas/ flexsnap-deploy:11.1.x.x-xxxx # docker push mycontainer.azurecr.io/veritas/ flexsnap-core:11.1.x.x-xxxx # docker push mycontainer.azurecr.io/veritas/ flexsnap-fluentd:11.1.x.x-xxxx # docker push mycontainer.azurecr.io/veritas/ flexsnap-datamover:11.1.x.x-xxxx
- Once the images are pushed to the container registry, execute the extension script
cp_extension.shthat was downloaded earlier, from the host where kubectl is installed. The script can be executed either by providing all the required input parameters in one command, or in an interactive way where you will be prompted for input.Gather the following parameters before running the script:
Parameter
Description
snapshotmanager_ip
Provide IP address or FQDN of the main NetBackup Snapshot Manager host.
target_image:tag
Target image tag created for the flexsnap-deploy image in step 3.
Example: mycontainer.azurecr.io/veritas/flexsnap-deploy:11.1.x.x-xxxx
namespace
NetBackup Snapshot Manager namespace that was created earlier in the preparation steps.
tag_key=tag_val
tag_keyandtag_valcan be retrieved by using these commands:Get the name of the node:
# kubectl get nodes | grep <node_name>
Get the tag key=value label:
# kubectl describe node <node_name> -n <namespace> | grep -i labels
Output example:
agentpool=cpuserpoolstorage_class
Kubernetes storage class that was created earlier in the preparation steps.
Example:
cloudpoint-scSize in GB
Volume size to be provisioned as per your scaling requirements.
workflow_token
Authentication token created from the NetBackup Web UI - Add extension dialog.
Note:
While deploying NetBackup Snapshot Manager Kubernetes extension, create a storage class and provide it as an input to the NetBackup Snapshot Manager extension installation script. By default file properties are open, hence it is recommended to create storage class by providing custom attributes in order to maintain the file/folder permissions created on extension under
/cloudpointdirectory. For more information, see Create a storage class section of the Azure product documentation.Run the script as an executable file:
Permit the script to run as an executable:
# chmod +x cp_extension.sh
Run the installation command with all the input parameters described in the above table:
./cp_extension.sh install -c <snapshotmanager_ip> -i <target_image:tag> -n <namespace> -p <tag_key=tag_val> -s <storage_class> -t <workflow_token> -k <Size (In GiB)>
Example:
./cp_extension.sh install Snapshot Manager image repository path.

Run the script as an interactive file:
Run the following command:
# ./cp_extension.sh install

This concludes the NetBackup Snapshot Manager extension installation on a managed Kubernetes cluster (in Azure cloud).
To verify that the extension is installed successfully:
Verify that the success message is displayed at the command prompt.
Verify that the extension is listed on the NetBackup Web UI.
Go to Cloud > NetBackup Snapshot Manager tab > click Advanced settings > go to NetBackup Snapshot Manager extensions tab and verify.
Run the following command and verify that there are five pods, namely,
flexsnap-deploy-xxx, flexsnap-fluentd-xxx, flexsnap-listener-xxx, flexsnap-fluentd-collector-xxxandflexsnap-datamover-xxxxare in Running state:# kubectl get pods -n <namespace>
Example: # kubectl get pods -n cloudpoint-system
