Openstack Cloud Driver
======================

:depends: `shade>=1.19.0 <https://pypi.python.org/pypi/shade>`_

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.

This OpenStack driver uses a the shade python module which is managed by the
OpenStack Infra team.  This module is written to handle all the different
versions of different OpenStack tools for salt, so most commands are just passed
over to the module to handle everything.

Provider
--------

There are two ways to configure providers for this driver.  The first one is to
just let shade handle everything, and configure using os-client-config_ and
setting up `/etc/openstack/clouds.yml`.

.. code-block:: yaml

    clouds:
      democloud:
        region_name: RegionOne
        auth:
          username: 'demo'
          password: secret
          project_name: 'demo'
          auth_url: 'http://openstack/identity'

And then this can be referenced in the salt provider based on the `democloud`
name.

.. code-block:: yaml

    myopenstack:
      driver: openstack
      cloud: democloud
      region_name: RegionOne

This allows for just using one configuration for salt-cloud and for any other
openstack tools which are all using `/etc/openstack/clouds.yml`

The other method allows for specifying everything in the provider config,
instead of using the extra configuration file.  This will allow for passing
salt-cloud configs only through pillars for minions without having to write a
clouds.yml file on each minion.abs

.. code-block:: yaml

    myopenstack:
      driver: openstack
      region_name: RegionOne
      auth:
        username: 'demo'
        password: secret
        project_name: 'demo'
        user_domain_name: default,
        project_domain_name: default,
        auth_url: 'http://openstack/identity'

Or if you need to use a profile to setup some extra stuff, it can be passed as a
`profile` to use any of the vendor_ config options.

.. code-block:: yaml

    myrackspace:
      driver: openstack
      profile: rackspace
      auth:
        username: rackusername
        api_key: myapikey
      region_name: ORD
      auth_type: rackspace_apikey

And this will pull in the profile for rackspace and setup all the correct
options for the auth_url and different api versions for services.


Profile
-------

Most of the options for building servers are just passed on to the
create_server_ function from shade.

The salt specific ones are:

  - ssh_key_file: The path to the ssh key that should be used to login to the machine to bootstrap it
  - ssh_key_file: The name of the keypair in openstack
  - userdata_template: The renderer to use if the userdata is a file that is templated. Default: False
  - ssh_interface: The interface to use to login for bootstrapping: public_ips, private_ips, floating_ips, fixed_ips
  - ignore_cidr: Specify a CIDR range of unreachable private addresses for salt to ignore when connecting

.. code-block:: yaml

    centos:
      provider: myopenstack
      image: CentOS 7
      size: ds1G
      ssh_key_name: mykey
      ssh_key_file: /root/.ssh/id_rsa

This is the minimum setup required.

If metadata is set to make sure that the host has finished setting up the
`wait_for_metadata` can be set.

.. code-block:: yaml

    centos:
      provider: myopenstack
      image: CentOS 7
      size: ds1G
      ssh_key_name: mykey
      ssh_key_file: /root/.ssh/id_rsa
      meta:
        build_config: rack_user_only
      wait_for_metadata:
        rax_service_level_automation: Complete
        rackconnect_automation_status: DEPLOYED

If your OpenStack instances only have private IP addresses and a CIDR range of
private addresses are not reachable from the salt-master, you may set your
preference to have Salt ignore it:

.. code-block:: yaml

    my-openstack-config:
      ignore_cidr: 192.168.0.0/16

Anything else from the create_server_ docs can be passed through here.

- **image**: Image dict, name or ID to boot with. image is required
  unless boot_volume is given.
- **flavor**: Flavor dict, name or ID to boot onto.
- **auto_ip**: Whether to take actions to find a routable IP for
  the server. (defaults to True)
- **ips**: List of IPs to attach to the server (defaults to None)
- **ip_pool**: Name of the network or floating IP pool to get an
  address from. (defaults to None)
- **root_volume**: Name or ID of a volume to boot from
  (defaults to None - deprecated, use boot_volume)
- **boot_volume**: Name or ID of a volume to boot from
  (defaults to None)
- **terminate_volume**: If booting from a volume, whether it should
  be deleted when the server is destroyed.
  (defaults to False)
- **volumes**: (optional) A list of volumes to attach to the server
- **meta**: (optional) A dict of arbitrary key/value metadata to
  store for this server. Both keys and values must be
  <=255 characters.
- **files**: (optional, deprecated) A dict of files to overwrite
  on the server upon boot. Keys are file names (i.e.
  ``/etc/passwd``) and values
  are the file contents (either as a string or as a
  file-like object). A maximum of five entries is allowed,
  and each file must be 10k or less.
- **reservation_id**: a UUID for the set of servers being requested.
- **min_count**: (optional extension) The minimum number of
  servers to launch.
- **max_count**: (optional extension) The maximum number of
  servers to launch.
- **security_groups**: A list of security group names
- **userdata**: user data to pass to be exposed by the metadata
  server this can be a file type object as well or a
  string.
- **key_name**: (optional extension) name of previously created
  keypair to inject into the instance.
- **availability_zone**: Name of the availability zone for instance
  placement.
- **block_device_mapping**: (optional) A list of dictionaries representing
  legacy block device mappings for this server. See
  `documentation <https://docs.openstack.org/nova/latest/user/block-device-mapping.html#block-device-mapping-v1-aka-legacy>`_
  for details.
- **block_device_mapping_v2**: (optional) A list of dictionaries representing
  block device mappings for this server. See
  `v2 documentation <https://docs.openstack.org/nova/latest/user/block-device-mapping.html#block-device-mapping-v2>`_
  for details.
- **nics**:  (optional extension) an ordered list of nics to be
  added to this server, with information about
  connected networks, fixed IPs, port etc.
- **scheduler_hints**: (optional extension) arbitrary key-value pairs
  specified by the client to help boot an instance
- **config_drive**: (optional extension) value for config drive
  either boolean, or volume-id
- **disk_config**: (optional extension) control how the disk is
  partitioned when the server is created.  possible
  values are 'AUTO' or 'MANUAL'.
- **admin_pass**: (optional extension) add a user supplied admin
  password.
- **timeout**: (optional) Seconds to wait, defaults to 60.
  See the ``wait`` parameter.
- **reuse_ips**: (optional) Whether to attempt to reuse pre-existing
  floating ips should a floating IP be
  needed (defaults to True)
- **network**: (optional) Network dict or name or ID to attach the
  server to.  Mutually exclusive with the nics parameter.
  Can also be be a list of network names or IDs or
  network dicts.
- **boot_from_volume**: Whether to boot from volume. 'boot_volume'
  implies True, but boot_from_volume=True with
  no boot_volume is valid and will create a
  volume from the image and use that.
- **volume_size**: When booting an image from volume, how big should
  the created volume be? Defaults to 50.
- **nat_destination**: Which network should a created floating IP
  be attached to, if it's not possible to
  infer from the cloud's configuration.
  (Optional, defaults to None)
- **group**: ServerGroup dict, name or id to boot the server in.
  If a group is provided in both scheduler_hints and in
  the group param, the group param will win.
  (Optional, defaults to None)

.. note::

    If there is anything added, that is not in this list, it can be added to an `extras`
    dictionary for the profile, and that will be to the create_server function.
