===================================
The :program:`nova` Shell Utility
===================================
.. program:: nova
.. highlight:: bash
The :program:`nova` shell utility interacts with OpenStack Nova API from the
command line. It supports the entirety of the OpenStack Nova API.
You'll need to provide :program:`nova` with your OpenStack Keystone user
information. You can do this with the `--os-username`, `--os-password`,
`--os-project-name` (`--os-project-id`), `--os-project-domain-name`
(`--os-project-domain-id`) and `--os-user-domain-name` (`--os-user-domain-id`)
options, but it's easier to just set them as environment variables by setting
some environment variables:
.. envvar:: OS_USERNAME
Your OpenStack Keystone user name.
.. envvar:: OS_PASSWORD
Your password.
.. envvar:: OS_PROJECT_NAME
The name of project for work.
.. envvar:: OS_PROJECT_ID
The ID of project for work.
.. envvar:: OS_PROJECT_DOMAIN_NAME
The name of domain containing the project.
.. envvar:: OS_PROJECT_DOMAIN_ID
The ID of domain containing the project.
.. envvar:: OS_USER_DOMAIN_NAME
The user's domain name.
.. envvar:: OS_USER_DOMAIN_ID
The user's domain ID.
.. envvar:: OS_AUTH_URL
The OpenStack Keystone endpoint URL.
.. envvar:: OS_COMPUTE_API_VERSION
The OpenStack Nova API version (microversion).
.. envvar:: OS_REGION_NAME
The Keystone region name. Defaults to the first region if multiple regions
are available.
.. envvar:: OS_TRUSTED_IMAGE_CERTIFICATE_IDS
A comma-delimited list of trusted image certificate IDs. Only used
with the ``nova boot`` and ``nova rebuild`` commands starting with the
2.63 microversion.
For example::
export OS_TRUSTED_IMAGE_CERTIFICATE_IDS=trusted-cert-id1,trusted-cert-id2
For example, in Bash you'd use::
export OS_USERNAME=yourname
export OS_PASSWORD=yadayadayada
export OS_PROJECT_NAME=myproject
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_AUTH_URL=http://<url-to-openstack-keystone>/identity
export OS_COMPUTE_API_VERSION=2.1
From there, all shell commands take the form::
nova <command> [arguments...]
Run :program:`nova help` to get a full list of all possible commands, and run
:program:`nova help <command>` to get detailed help for that command.
For more information, see :doc:`the command reference </cli/nova>`.
