Synopsis

  • Get inventory hosts from OpenNebula cloud.

  • Uses an YAML configuration file ending with either opennebula.yml or opennebula.yaml to set parameter values.

  • Uses api_authfile, ~/.one/one_auth, or ONE_AUTH pointing to a OpenNebula credentials file.

Parameters

Parameter

Comments

api_authfile

string

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.

Configuration:

api_password

string

Password or a token of the user to login into OpenNebula RPC server.

If not set, the value of the ONE_PASSWORD environment variable is used.

Configuration:

api_url

string / required

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.

Configuration:

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.

Configuration:

compose

dictionary

Create vars from jinja2 expressions.

Default: {}

filter_by_label

string

Only return servers filtered by this label.

group_by_labels

boolean

Create host groups by vm labels

Choices:

  • false

  • true ← (default)

groups

dictionary

Add hosts to group based on Jinja2 conditionals.

Default: {}

hostname

string

Field to match the hostname. Note v4_first_ip corresponds to the first IPv4 found on VM.

Choices:

  • "v4_first_ip" ← (default)

  • "v6_first_ip"

  • "name"

keyed_groups

list / elements=dictionary

Add hosts to group based on the values of a variable.

Default: []

default_value

string

added in ansible-core 2.12

The default value when the host variable’s value is an empty string.

This option is mutually exclusive with trailing_separator.

key

string

The key from input dictionary used to generate groups

parent_group

string

parent group for keyed group

prefix

string

A keyed group name will start with this prefix

Default: ""

separator

string

separator used to build the keyed group name

Default: "_"

trailing_separator

boolean

added in ansible-core 2.12

Set this option to False to omit the separator after the host variable when the value is an empty string.

This option is mutually exclusive with default_value.

Choices:

  • false

  • true ← (default)

leading_separator

boolean

added in ansible-core 2.11

Use in conjunction with keyed_groups.

By default, a keyed group that does not have a prefix or a separator provided will have a name that starts with an underscore.

This is because the default prefix is “” and the default separator is “_”.

Set this option to False to omit the leading underscore (or other separator) if no prefix is given.

If the group name is derived from a mapping the separator is still used to concatenate the items.

To not use a separator in the group name at all, set the separator for the keyed group to an empty string instead.

Choices:

  • false

  • true ← (default)

plugin

string / required

Token that ensures this is a source file for the ‘opennebula’ plugin.

Choices:

  • "community.general.opennebula"

strict

boolean

If yes make invalid entries a fatal error, otherwise skip and continue.

Since it is possible to use facts in the expressions they might not always be available and we ignore those errors by default.

Choices:

  • false ← (default)

  • true

use_extra_vars

boolean

added in ansible-core 2.11

Merge extra vars into the available variables for composition (highest precedence).

Choices:

  • false ← (default)

  • true

Configuration:

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
