community.general.one_vm module – Creates or terminates OpenNebula instances

Note

This module is part of the community.general collection (version 5.4.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.general.

To use it in a playbook, specify: community.general.one_vm.

Synopsis

  • Manages OpenNebula instances

Requirements

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

  • pyone

Parameters

Parameter

Comments

api_password

string

Password of the user to login into OpenNebula RPC server. If not set

then the value of the ONE_PASSWORD environment variable is used.

if both api_username or api_password are not set, then it will try

authenticate with ONE auth file. Default path is “~/.one/one_auth”.

Set environment variable ONE_AUTH to override this path.

api_url

string

URL of the OpenNebula RPC server.

It is recommended to use HTTPS so that the username/password are not

transferred over the network unencrypted.

If not set then the value of the ONE_URL environment variable is used.

api_username

string

Name of the user to login into the OpenNebula RPC server. If not set

then the value of the ONE_USERNAME environment variable is used.

attributes

dictionary

A dictionary of key/value attributes to add to new instances, or for

setting state of instances with these attributes.

Keys are case insensitive and OpenNebula automatically converts them to upper case.

Be aware NAME is a special attribute which sets the name of the VM when it’s deployed.

# character(s) can be appended to the NAME and the module will automatically add

indexes to the names of VMs.

For example’:’ NAME':' foo-### would create VMs with names foo-000, foo-001,…

When used with count_attributes and exact_count the module will

match the base name without the index part.

Default: {}

count

integer

Number of instances to launch

Default: 1

count_attributes

dictionary

A dictionary of key/value attributes that can only be used with

exact_count to determine how many nodes based on a specific

attributes criteria should be deployed. This can be expressed in

multiple ways and is shown in the EXAMPLES section.

count_labels

list / elements=string

A list of labels that can only be used with exact_count to determine

how many nodes based on a specific labels criteria should be deployed.

This can be expressed in multiple ways and is shown in the EXAMPLES

section.

cpu

float

Percentage of CPU divided by 100 required for the new instance. Half a

processor is written 0.5.

datastore_id

integer

added in 0.2.0 of community.general

Name of Datastore to use to create a new instace

datastore_name

string

added in 0.2.0 of community.general

Name of Datastore to use to create a new instace

disk_saveas

dictionary

Creates an image from a VM disk.

It is a dictionary where you have to specify name of the new image.

Optionally you can specify disk_id of the disk you want to save. By default disk_id is 0.

NOTE‘:’ This operation will only be performed on the first VM (if more than one VM ID is passed)

and the VM has to be in the poweredoff state.

Also this operation will fail if an image with specified name already exists.

disk_size

list / elements=string

The size of the disk created for new instances (in MB, GB, TB,…).

NOTE’:’ If The Template hats Multiple Disks the Order of the Sizes is

matched against the order specified in template_id/template_name.

exact_count

integer

Indicates how many instances that match count_attributes and

count_labels parameters should be deployed. Instances are either

created or terminated based on this value.

NOTE’:’ Instances with the least IDs will be terminated first.

group_id

integer

ID of the group which will be set as the group of the instance

hard

boolean

Reboot, power-off or terminate instances hard

Choices:

  • no ← (default)

  • yes

instance_ids

aliases: ids

list / elements=integer

A list of instance ids used for states’:’ absent, running, rebooted, poweredoff

labels

list / elements=string

A list of labels to associate with new instances, or for setting

state of instances with these labels.

Default: []

memory

string

The size of the memory for new instances (in MB, GB, …)

mode

string

Set permission mode of the instance in octet format, e.g. 600 to give owner use and manage and nothing to group and others.

networks

list / elements=dictionary

A list of dictionaries with network parameters. See examples for more details.

Default: []

owner_id

integer

ID of the user which will be set as the owner of the instance

persistent

boolean

added in 0.2.0 of community.general

Create a private persistent copy of the template plus any image defined in DISK, and instantiate that copy.

Choices:

  • no ← (default)

  • yes

state

string

present - create instances from a template specified with template_id/template_name.

running - run instances

poweredoff - power-off instances

rebooted - reboot instances

absent - terminate instances

Choices:

  • present ← (default)

  • absent

  • running

  • rebooted

  • poweredoff

template_id

integer

ID of a VM template to use to create a new instance

template_name

string

Name of VM template to use to create a new instace

vcpu

integer

Number of CPUs (cores) new VM will have.

vm_start_on_hold

boolean

Set to true to put vm on hold while creating

Choices:

  • no ← (default)

  • yes

wait

boolean

Wait for the instance to reach its desired state before returning. Keep

in mind if you are waiting for instance to be in running state it

doesn’t mean that you will be able to SSH on that machine only that

boot process have started on that instance, see ‘wait_for’ example for

details.

Choices:

  • no

  • yes ← (default)

wait_timeout

integer

How long before wait gives up, in seconds

Default: 300
