module: os_server
short_description: Create/Delete Compute Instances from OpenStack
extends_documentation_fragment: openstack
version_added: "2.0"
author: "Monty Taylor (@emonty)"
description:
- Create or Remove compute instances from OpenStack.
options:
name:
description:
- Name that has to be given to the instance
required: true
image:
description:
- The name or id of the base image to boot.
required: true
image_exclude:
description:
- 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)"
flavor:
description:
- The name or id of the flavor in which the new instance has to be
created. Mutually exclusive with flavor_ram
required: false
default: 1
flavor_ram:
description:
- 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.
required: false
default: 1
flavor_include:
description:
- 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.
key_name:
description:
- The key pair name to be used when creating a instance
required: false
default: None
security_groups:
description:
- Names of the security groups to which the instance should be
added. This may be a YAML list or a comma separated string.
required: false
default: None
network:
description:
- 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.
required: false
default: None
nics:
description:
- 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.'
required: false
default: None
auto_ip:
description:
- Ensure instance has public ip however the cloud wants to do that
required: false
default: 'yes'
aliases: ['auto_floating_ip', 'public_ip']
floating_ips:
description:
- list of valid floating IPs that pre-exist to assign to this node
required: false
default: None
floating_ip_pools:
description:
- Name of floating IP pool from which to choose a floating IP
required: false
default: None
meta:
description:
- '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"'
required: false
default: None
wait:
description:
- If the module should wait for the instance to be created.
required: false
default: 'yes'
timeout:
description:
- The amount of time the module should wait for the instance to get
into active state.
required: false
default: 180
config_drive:
description:
- Whether to boot the server with config drive enabled
required: false
default: 'no'
userdata:
description:
- Opaque blob of data which is made available to the instance
required: false
default: None
boot_from_volume:
description:
- Should the instance boot from a persistent volume created based on
the image given. Mututally exclusive with boot_volume.
required: false
default: false
volume_size:
description:
- The size of the volume to create in GB if booting from volume based
on an image.
boot_volume:
description:
- Volume name or id to use as the volume to boot from. Implies
boot_from_volume. Mutually exclusive with image and boot_from_volume.
required: false
default: None
aliases: ['root_volume']
terminate_volume:
description:
- If true, delete volume when deleting instance (if booted from volume)
default: false
volumes:
description:
- A list of preexisting volumes names or ids to attach to the instance
required: false
default: []
scheduler_hints:
description:
- Arbitrary key/value pairs to the scheduler for custom use
required: false
default: None
version_added: "2.1"
state:
description:
- Should the resource be present or absent.
choices: [present, absent]
default: present
delete_fip:
description:
- When I(state) is absent and this option is true, any floating IP
associated with the instance will be deleted along with the instance.
required: false
default: false
version_added: "2.2"
reuse_ips:
description:
- When I(auto_ip) is true and this option is true, the I(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 I(delete_fip).
required: false
default: true
version_added: "2.2"
requirements:
- "python >= 2.6"
- "shade"
