salt.modules.nova

Module for handling OpenStack Nova calls

depends:
  • novaclient Python module
configuration:

This module is not usable until the user, password, tenant, and auth URL are specified either in a pillar or in the minion's config file. For example:

keystone.user: admin
keystone.password: verybadpass
keystone.tenant: admin
keystone.auth_url: 'http://127.0.0.1:5000/v2.0/'
# Optional
keystone.region_name: 'RegionOne'

If configuration for multiple OpenStack accounts is required, they can be set up as different configuration profiles: For example:

openstack1:
  keystone.user: admin
  keystone.password: verybadpass
  keystone.tenant: admin
  keystone.auth_url: 'http://127.0.0.1:5000/v2.0/'

openstack2:
  keystone.user: admin
  keystone.password: verybadpass
  keystone.tenant: admin
  keystone.auth_url: 'http://127.0.0.2:5000/v2.0/'

With this configuration in place, any of the nova functions can make use of a configuration profile by declaring it explicitly. For example:

salt '*' nova.flavor_list profile=openstack1

To use keystoneauth1 instead of keystoneclient, include the use_keystoneauth option in the pillar or minion config.

Note

This is required to use keystone v3 as for authentication.

keystone.user: admin
keystone.password: verybadpass
keystone.tenant: admin
keystone.auth_url: 'http://127.0.0.1:5000/v3/'
keystone.use_keystoneauth: true
keystone.verify: '/path/to/custom/certs/ca-bundle.crt'

Note

By default the nova module will attempt to verify its connection utilizing the system certificates. If you need to verify against another bundle of CA certificates or want to skip verification altogether you will need to specify the verify option. You can specify True or False to verify (or not) against system certificates, a path to a bundle or CA certs to check against, or None to allow keystoneauth to search for the certificates on its own. (defaults to True)

salt.modules.nova.boot(name, flavor_id=0, image_id=0, profile=None, timeout=300)

Boot (create) a new instance

name
