Synopsis ¶

Create or Remove compute instances from OpenStack.

Requirements ¶

The below requirements are needed on the host that executes this module.

openstacksdk
python >= 2.7

Parameters ¶

Parameter	Choices/Defaults	Comments
api_timeout		How long should the socket layer wait before timing out for API calls. If this is omitted, nothing will be passed to the requests library.
auth		Dictionary containing auth information as needed by the cloud's auth plugin strategy. For the default password plugin, this would contain auth_url, username, password, project_name and any information about domains if the cloud supports them. For other plugins, this param will need to contain whatever parameters that auth plugin requires. This parameter is not needed if a named cloud is provided or OpenStack OS_* environment variables are present.
auth_type		Name of the auth plugin to use. If the cloud uses something other than password authentication, the name of the plugin should be indicated here and the contents of the auth parameter should be updated accordingly.
auto_ip bool	Choices: no yes ←	Ensure instance has public ip however the cloud wants to do that aliases: auto_floating_ip, public_ip
availability_zone		Availability zone in which to create the server.
boot_from_volume bool	Choices: no ← yes	Should the instance boot from a persistent volume created based on the image given. Mututally exclusive with boot_volume.
boot_volume		Volume name or id to use as the volume to boot from. Implies boot_from_volume. Mutually exclusive with image and boot_from_volume. aliases: root_volume
cacert		A path to a CA Cert bundle that can be used as part of verifying SSL API requests.
cert		A path to a client certificate to use as part of the SSL transaction.
cloud		Named cloud or cloud config to operate against. If cloud is a string, it references a named cloud config as defined in an OpenStack clouds.yaml file. Provides default values for auth and auth_type. This parameter is not needed if auth is provided or if OpenStack OS_* environment variables are present. If cloud is a dict, it contains a complete cloud configuration like would be in a section of clouds.yaml.
config_drive bool	Choices: no ← yes	Whether to boot the server with config drive enabled
delete_fip bool (added in 2.2)	Choices: no ← yes	When state is absent and this option is true, any floating IP associated with the instance will be deleted along with the instance.
flavor	Default: 1	The name or id of the flavor in which the new instance has to be created. Mutually exclusive with flavor_ram
flavor_include		Text to use to filter flavor names, for the case, such as Rackspace, where there are multiple flavors that have the same ram count. flavor_include is a positive match filter - it must exist in the flavor name.
flavor_ram	Default: 1	The minimum amount of ram in MB that the flavor in which the new instance has to be created must have. Mutually exclusive with flavor.
floating_ip_pools		Name of floating IP pool from which to choose a floating IP
floating_ips		list of valid floating IPs that pre-exist to assign to this node
image required		The name or id of the base image to boot.
image_exclude		Text to use to filter image names, for the case, such as HP, where there are multiple image names matching the common identifying portions. image_exclude is a negative match filter - it is text that may not exist in the image name. Defaults to "(deprecated)"
interface (added in 2.3)	Choices: public ← internal admin	Endpoint URL type to fetch from the service catalog. aliases: endpoint_type
key		A path to a client key to use as part of the SSL transaction.
key_name		The key pair name to be used when creating a instance
meta		A list of key value pairs that should be provided as a metadata to the new instance or a string containing a list of key-value pairs. Eg: meta: "key1=value1,key2=value2"
name required		Name that has to be given to the instance. It is also possible to specify the ID of the instance instead of its name if state is absent.
network		Name or ID of a network to attach this instance to. A simpler version of the nics parameter, only one of network or nics should be supplied.
nics		A list of networks to which the instance's interface should be attached. Networks may be referenced by net-id/net-name/port-id or port-name. Also this accepts a string containing a list of (net/port)-(id/name) Eg: nics: "net-id=uuid-1,port-name=myport" Only one of network or nics should be supplied.
region_name		Name of the region.
reuse_ips bool (added in 2.2)	Choices: no yes ←	When auto_ip is true and this option is true, the auto_ip code will attempt to re-use unassigned floating ips in the project before creating a new one. It is important to note that it is impossible to safely do this concurrently, so if your use case involves concurrent server creation, it is highly recommended to set this to false and to delete the floating ip associated with a server when the server is deleted using delete_fip.
scheduler_hints (added in 2.1)		Arbitrary key/value pairs to the scheduler for custom use
security_groups		Names of the security groups to which the instance should be added. This may be a YAML list or a comma separated string.
state	Choices: present ← absent	Should the resource be present or absent.
terminate_volume bool	Choices: no ← yes	If `yes`, delete volume when deleting instance (if booted from volume)
timeout	Default: 180	The amount of time the module should wait for the instance to get into active state.
userdata		Opaque blob of data which is made available to the instance
verify bool	Choices: no yes	Whether or not SSL API requests should be verified. Before 2.3 this defaulted to True. aliases: validate_certs
volume_size		The size of the volume to create in GB if booting from volume based on an image.
volumes	Default: []	A list of preexisting volumes names or ids to attach to the instance
wait bool	Choices: no yes ←	If the module should wait for the instance to be created.

Notes ¶

Note

The standard OpenStack environment variables, such as OS_USERNAME may be used instead of providing explicit values.
Auth information is driven by os-client-config, which means that values can come from a yaml config file in /etc/ansible/openstack.yaml, /etc/openstack/clouds.yaml or ~/.config/openstack/clouds.yaml, then from standard environment variables, then finally by explicit parameters in plays. More information can be found at http://docs.openstack.org/developer/os-client-config
