Tips and Tricks
~~~~~~~~~~~~~~~
Kolla ships with several utilities intended to facilitate ease of operation.
Kolla Ansible CLI
-----------------
``tools/cleanup-containers`` is used to remove deployed containers from the
system. This can be useful when you want to do a new clean deployment. It will
preserve the registry and the locally built images in the registry, but will
remove all running Kolla containers from the local Docker daemon. It also
removes the named volumes.
``tools/cleanup-host`` is used to remove remnants of network changes
triggered on the Docker host when the neutron-agents containers are launched.
This can be useful when you want to do a new clean deployment, particularly one
changing the network topology.
``tools/cleanup-images --all`` is used to remove all Docker images built by
Kolla from the local Docker cache.
When running the ``kolla-ansible`` CLI, additional arguments may be passed to
``ansible-playbook`` via the ``EXTRA_OPTS`` environment variable.
``kolla-ansible -i INVENTORY deploy`` is used to deploy and start all Kolla
containers.

Passwords

The following commands manage the Kolla Ansible passwords file.
``kolla-mergepwd --old OLD_PASSWDS --new NEW_PASSWDS --final FINAL_PASSWDS``

passwords during upgrade of Kolla release. The workflow is:
