OpenStack Nova Cloud Module
===========================
PLEASE NOTE: This module is currently in early development, and considered to
be experimental and unstable. It is not recommended for production use. Unless
you are actively developing code in this module, you should use the OpenStack
module instead.
OpenStack is an open source project that is in use by a number a cloud
providers, each of which have their own ways of using it.
The OpenStack Nova module for Salt Cloud was bootstrapped from the OpenStack
module for Salt Cloud, which uses a libcloud-based connection. The Nova module
is designed to use the nova and glance modules already built into Salt.
These modules use the Python novaclient and glanceclient libraries,
respectively. In order to use this module, the proper salt configuration must
also be in place. This can be specified in the master config, the minion
config, a set of grains or a set of pillars.
.. code-block:: yaml
my_openstack_profile:
keystone.user: admin
keystone.password: verybadpass
keystone.tenant: admin
keystone.auth_url: 'http://127.0.0.1:5000/v2.0/'
Note that there is currently a dependency upon netaddr. This can be installed
on Debian-based systems by means of the python-netaddr package.
This module currently requires the latest develop branch of Salt to be
installed.
This module has been tested to work with HP Cloud and Rackspace. See the
documentation for specific options for either of these providers. These
examples could be set up in the cloud configuration at
``/etc/salt/cloud.providers`` or
``/etc/salt/cloud.providers.d/openstack.conf``:
.. code-block:: yaml
my-openstack-config:
# The ID of the minion that will execute the salt nova functions
auth_minion: myminion
# The name of the configuration profile to use on said minion
config_profile: my_openstack_profile
ssh_key_name: mykey
provider: nova
userdata_file: /tmp/userdata.txt
For local installations that only use private IP address ranges, the
following option may be useful. Using the old syntax:
Note: For api use, you will need an auth plugin. The base novaclient does not
support apikeys, but some providers such as rackspace have extended keystone to
accept them
.. code-block:: yaml
my-openstack-config:
# Ignore IP addresses on this network for bootstrap
ignore_cidr: 192.168.50.0/24
my-nova:
identity_url: 'https://identity.api.rackspacecloud.com/v2.0/'
compute_region: IAD
user: myusername
password: mypassword
tenant: <userid>
provider: nova
my-api:
identity_url: 'https://identity.api.rackspacecloud.com/v2.0/'
compute_region: IAD
user: myusername
api_key: <api_key>
os_auth_plugin: rackspace
tenant: <userid>
provider: nova
networks:
- net-id: 47a38ff2-fe21-4800-8604-42bd1848e743
- net-id: 00000000-0000-0000-0000-000000000000
- net-id: 11111111-1111-1111-1111-111111111111
Note: You must include the default net-ids when setting networks or the server
will be created without the rest of the interfaces
Note: For rackconnect v3, rackconnectv3 needs to be specified with the
rackconnect v3 cloud network as it's variable
