The fun part about having multiple vendors providing the same cloud
is that while their APIs are the same, what they do with their metadata
tends to be ... fun. So in order to be able to express sanely what you
want without needing to stick tons of unreadable uuids in your config,
it turns out what sometimes you need to further filter image and flavor
names. Specific examples are (deprecated) images in HP Cloud and the
Standard and Performance flavors on Rackspace.
Putting uuid and numberic identifies in playbooks is fragile, especially
with cloud providers who change them out from under you. Asking for
Ubuntu 14.04 is consistent, the UUID associated with that is not. Add
mutually exclusive parameters to allow for specifying images by name and
flavors by RAM amount.
Taking a page out of the ec2 config, make sure that all of the
OpenStack modules handle the inbound auth config in the same way.
The one outlier is keystone wrt auth_url.
The OpenStack client utilities consume a set of input environment
variables for things like username and auth_url, so it's very
common for OpenStack users to have such settings set in their
environment. Indeed, things like devstack also output a shell file
to be sourced to set them. Although in a playbook it's entirely
expected that variables should be used to pass in system settings
like api passwords, for ad-hoc command line usage, needing to pass
in five parameters which are almost certainly in the environment
already reduces the utility.
Grab the environment variables and inject them as default. Special care
is taken to ensure that in the case where the values are not found, the
behavior of which parameters are required is not altered.
The floating-ip extension, while pretty ubiquitous, is not a
foregone conclusion. Specifically, Rackspace, while also
served by the rax module, is a valid OpenStack cloud and can
be interacted with directly via nova interfaces.
Add support for determining public and private IPs for
OpenStack clouds that don't use floating ips by reading
the public and private keys from the addresses dict.
If the region name is specified in the config, we need to pass it
in to the nova client constructor. Since key_name is similarly optional,
go ahead and handle both parameters the same.
The desires around getting a floating ip associated with a pool and
getting a floating ip not associated with a pool is just different
enough that following it as one set of nested ifs is tricky. Split
the function into two, one for the pool and one for the non-pool logic.

When there is an Openstack instance that has a name that's a partial match
for module.params['name'], but a server with name module.params['name']
doesn't yet exist, this module would fail with a list index out of bounds
error. This fixes that by filtering by exact name and only then getting the
server from the list if the list is still not empty.

Since deletion do not check the type of image or anything,
and since that's tedious to keep track of the image_id and
just adding noise to add image_id for nothing, this commit
just relax the requirement.

This extension was added less than 6 month ago, and so cannot be used on a release
older than Grizzly ( like Folsom ).
Commit of the extension : https://review.openstack.org/#/c/21453/
See https://wiki.openstack.org/wiki/ReleaseNotes/Grizzly#Key_New_Features_2
Migrated all examples: in DOCUMENTATION=''' string to standalone EXAMPLES=''' string
Added deprecation warning to moduledev.rst and remove deprecated example from it
Fixed up a few typos and uppercased some acronyms.
add consistency to how EXAMPLES are formatted
