Create an Inventory from CloudVision¶
In large setups, it might be beneficial to construct your inventory based on CloudVision. The from-cvp
entrypoint of the get
command enables the user to create an ANTA inventory from CloudVision.
Info
The current implementation only works with on-premises CloudVision instances, not with CloudVision as a Service (CVaaS).
Command overview¶
Usage: anta get from-cvp [OPTIONS]
Build ANTA inventory from CloudVision.
NOTE: Only username/password authentication is supported for on-premises CloudVision instances.
Token authentication for both on-premises and CloudVision as a Service (CVaaS) is not supported.
Options:
-o, --output FILE Path to save inventory file [env var: ANTA_INVENTORY;
required]
--overwrite Do not prompt when overriding current inventory [env
var: ANTA_GET_FROM_CVP_OVERWRITE]
-host, --host TEXT CloudVision instance FQDN or IP [required]
-u, --username TEXT CloudVision username [required]
-p, --password TEXT CloudVision password [required]
-c, --container TEXT CloudVision container where devices are configured
--ignore-cert By default connection to CV will use HTTPS
certificate, set this flag to disable it [env var:
ANTA_GET_FROM_CVP_IGNORE_CERT]
--help Show this message and exit.
The output is an inventory where the name of the container is added as a tag for each host:
anta_inventory:
hosts:
- host: 192.168.0.13
name: leaf2
tags:
- pod1
- host: 192.168.0.15
name: leaf4
tags:
- pod2
Warning
The current implementation only considers devices directly attached to a specific container when using the --cvp-container
option.
Creating an inventory from multiple containers¶
If you need to create an inventory from multiple containers, you can use a bash command and then manually concatenate files to create a single inventory file:
$ for container in pod01 pod02 spines; do anta get from-cvp -ip <cvp-ip> -u cvpadmin -p cvpadmin -c $container -d test-inventory; done
