Running the Playbooks
Enable the NVUE API
Cumulus Linux 5.5 and earlier disables the NVUE REST API by default. If you want to use any of the object specific modules or the api module, you need to enable the NVUE REST API with the following commands on the switch:
cumulus@switch:~$ sudo ln -s /etc/nginx/sites-{available,enabled}/nvue.conf
cumulus@switch:~$ sudo sed -i 's/listen localhost:8765 ssl;/listen \[::\]:8765 ipv6only=off ssl;/g' /etc/nginx/sites-available/nvue.conf
cumulus@switch:~$ sudo systemctl restart nginx
You can find a sample playbook that enables the NVUE REST API across all of the switches here. Download the file and run it against the switches.
cumulus@oob-management:~$ curl -o enable-nvue-api.yml https://gitlab.com/nvidia-networking/systems-engineering/nvue/-/raw/main/examples/playbooks/enable-nvue-api.yml
cumulus@oob-management:~$ curl -o hosts https://gitlab.com/nvidia-networking/systems-engineering/nvue/-/raw/main/examples/hosts
cumulus@oob-management:~$ ansible-playbook enable-nvue-api.yml -i hosts
Sample Playbooks
You can find additional example playbooks and host files in the <collections_directory>/nvidia/nvue/examples directory or in the git repository here.
cumulus@oob-management:~$ ls ~/.ansible/collections/ansible_collections/nvidia/nvue/examples/
collections host_vars hosts playbooks
You can run any of the sample playbooks in the playbooks directory.
cumulus@oob-management:~$ ls ~/.ansible/collections/ansible_collections/nvidia/nvue/examples/playbooks
api.yml gather-config-multiple.yml
bridge.yml gather-config.yml
command.yml interface.yml
evpn-multihoming-leaf01.yml revision.yml
evpn-symmetric-leaf01.yml static-vxlan-leaf01.yml
The gather-config.yml uses the high-level api module to fetch the root configuration and the object-level interface module to fetch interface configuration.
cumulus@oob-management:~$ cd ~/.ansible/collections/ansible_collections/nvidia/nvue/examples/
cumulus@oob-management:~$ cat playbooks/gather-config.yml

Run the playbook. Optionally, you can add the -v parameter to increase verbosity of the playbook execution.
