To use it in a playbook, specify: ovirt.ovirt.ovirt.

New in ovirt.ovirt 1.0.0

Synopsis

  • ovirt-engine-sdk-python >= 4.2.4

Parameters

Parameter

Comments

cache

boolean

Toggle to enable/disable the caching of the inventory’s source data, requires a cache plugin setup to work.

Choices:

  • false ← (default)

  • true

Configuration:

cache_connection

string

Cache connection data or path, read cache plugin documentation for specifics.

Configuration:

cache_plugin

string

Cache plugin to use for the inventory’s source data.

Default: "memory"

Configuration:

cache_prefix

string

Prefix to use for cache plugin files/tables.

Default: "ansible_inventory_"

Configuration:

cache_timeout

integer

Cache duration in seconds.

Default: 3600

Configuration:

compose

dictionary

Create vars from jinja2 expressions.

Default: {}

groups

dictionary

Add hosts to group based on Jinja2 conditionals.

Default: {}

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 None or an empty string.

This option is mutually exclusive with keyed_groups[].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 keyed_groups[].separator after the host variable when the value is None or an empty string.

This option is mutually exclusive with keyed_groups[].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)

ovirt_cafile

string

path to ovirt-engine CA file. If ovirt_cafile parameter is not set and ovirt_insecure is not True, system wide CA certificate store is used.

ovirt_hostname_preference

list / elements=string

List of options that describe the ordering for which hostnames should be assigned.

See https://ovirt.github.io/ovirt-engine-api-model/master/#types/vm for available attributes.

Default: ["fqdn", "name"]

ovirt_insecure

string

A boolean flag that indicates if the server TLS certificate and host name should be checked.

ovirt_password

string / required

ovirt authentication password.

Configuration:

ovirt_query_filter

string

dictionary of filter key-values to query VM’s. See https://ovirt.github.io/ovirt-engine-sdk/master/services.m.html#ovirtsdk4.services.VmsService.list for filter parameters.

ovirt_url

string / required

URL to ovirt-engine API.

Configuration:

ovirt_username

string / required

ovirt authentication user.

Configuration:

plugin

string / required

the name of this plugin, it should always be set to ‘ovirt’ for this plugin to recognise it as it’s own.

Choices:

  • "ovirt"

  • "ovirt.ovirt.ovirt"

  • "redhat.rhv.ovirt"

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:

Note

Configuration entries listed above for each entry type (Ansible variable, environment variable, and so on) 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. The entry types are also ordered by precedence from low to high priority order. For example, an ansible.cfg entry (further up in the list) is overwritten by an Ansible variable (further down in the list).

Notes

Note

  • Inventories are not finalized at this stage, so the auto populated all and ungrouped groups will only reflect what previous inventory sources explicitly added to them.

  • Runtime ‘magic variables’ are not available during inventory construction. For example, groups and hostvars do not exist yet.

Examples

# $ wget "https://engine/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA" -O /path/to/ca.pem

plugin: ovirt.ovirt.ovirt
ovirt_url: https://engine/ovirt-engine/api
ovirt_cafile: /path/to/ca.pem
ovirt_username: ansible-tester
ovirt_password: secure
ovirt_query_filter:
  search: 'name=myvm AND cluster=mycluster'
  case_sensitive: false
  max: 15
keyed_groups:
  - key: cluster
    prefix: 'cluster'
