Synopsis

  • Get inventory hosts from OpenNebula cloud.

  • 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:

  • Environment variable: ONE_AUTH

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:

  • Environment variable: ONE_PASSWORD

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:

  • Environment variable: ONE_URL

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:

  • Environment variable: ONE_USERNAME

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:

  • no

  • yes ← (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 2.12 of ansible.builtin

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 2.12 of ansible.builtin

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:

  • no

  • yes ← (default)

leading_separator

boolean

added in 2.11 of ansible.builtin

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:

  • no

  • yes ← (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:

  • no ← (default)

  • yes

use_extra_vars

boolean

added in 2.11 of ansible.builtin

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

Choices:

  • no ← (default)

  • yes

Configuration:

  • INI entry:

    [inventory_plugins]
    use_extra_vars = no
    
  • Environment variable: ANSIBLE_INVENTORY_USE_EXTRA_VARS

Examples

# inventory_opennebula.yml file in YAML format
# Example command line: ansible-inventory --list -i inventory_opennebula.yml

# Pass a label filter to the API
plugin: community.general.opennebula
api_url: https://opennebula:2633/RPC2
filter_by_label: Cache

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.
