auth_kind

- / required

  • application
  • serviceaccount
  • machineaccount

env:GCP_AUTH_KIND

The type of credential used.

cache

boolean

  • no

  • yes

ini entries: [inventory]cache = no


env:ANSIBLE_INVENTORY_CACHE

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

cache_connection

string

ini entries: [defaults]fact_caching_connection = VALUE

[inventory]cache_connection = VALUE


env:ANSIBLE_CACHE_PLUGIN_CONNECTION

env:ANSIBLE_INVENTORY_CACHE_CONNECTION

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

cache_plugin

string

Default:

"memory"

ini entries: [defaults]fact_caching = memory

[inventory]cache_plugin = memory


env:ANSIBLE_CACHE_PLUGIN

env:ANSIBLE_INVENTORY_CACHE_PLUGIN

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

cache_prefix

-

Default:

"ansible_inventory_"

ini entries: [default]fact_caching_prefix = ansible_inventory_

[inventory]cache_prefix = ansible_inventory_


env:ANSIBLE_CACHE_PLUGIN_PREFIX

env:ANSIBLE_INVENTORY_CACHE_PLUGIN_PREFIX

Prefix to use for cache plugin files/tables

cache_timeout

integer

Default:

3600

ini entries: [defaults]fact_caching_timeout = 3600

[inventory]cache_timeout = 3600


env:ANSIBLE_CACHE_PLUGIN_TIMEOUT

env:ANSIBLE_INVENTORY_CACHE_TIMEOUT

Cache duration in seconds

compose

dictionary

Default:

{}

Create vars from jinja2 expressions.

filters

list

A list of filter value pairs. Available filters are listed here https://cloud.google.com/compute/docs/reference/rest/v1/instances/aggregatedList. Each additional filter in the list will act be added as an AND condition (filter1 and filter2)

groups

dictionary

Default:

{}

Add hosts to group based on Jinja2 conditionals.

hostnames

list

Default:

["public_ip", "private_ip", "name"]

A list of options that describe the ordering for which hostnames should be assigned. Currently supported hostnames are 'public_ip', 'private_ip', or 'name'.

keyed_groups

list

Default:

[]

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

plugin

- / required

  • gcp_compute

token that ensures this is a source file for the 'gcp_compute' plugin.

projects

list / required

A list of projects in which to describe GCE instances.

retrieve_image_info

boolean

added in 2.8

  • no

  • yes

Populate the image host fact for the instances returned with the GCP image name

By default this plugin does not attempt to resolve the boot image of an instance to the image name cataloged in GCP because of the performance overhead of the task.

Unless this option is enabled, the image host variable will be null

scopes

list

Default:

env:GCP_SCOPES

list of authentication scopes

service_account_contents

string

added in 2.8.2

env:GCP_SERVICE_ACCOUNT_CONTENTS

A string representing the contents of a Service Account JSON file. This should not be passed in as a dictionary, but a string that has the exact contents of a service account json file (valid JSON).

service_account_email

-

env:GCP_SERVICE_ACCOUNT_EMAIL

An optional service account email address if machineaccount is selected and the user does not wish to use the default email.

service_account_file

path

env:GCP_SERVICE_ACCOUNT_FILE

env:GCE_CREDENTIALS_FILE_PATH

The path of a Service Account JSON file if serviceaccount is selected as type.

strict

boolean

  • no

  • yes

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.

use_contrib_script_compatible_sanitization

boolean

added in 2.8

  • no

  • yes

By default this plugin is using a general group name sanitization to create safe and usable group names for use in Ansible. This option allows you to override that, in efforts to allow migration from the old inventory script.

For this to work you should also turn off the TRANSFORM_INVALID_GROUP_CHARS setting, otherwise the core engine will just use the standard sanitization on top.

This is not the default as such names break certain functionality as not all characters are valid Python identifiers which group names end up being used as.

vars_prefix

-

Default:

""

prefix to apply to host variables, does not include facts nor params

zones

list

A list of regions in which to describe GCE instances. If none provided, it defaults to all zones available to a given project.



Examples

plugin: gcp_compute
zones: # populate inventory with instances in these regions
  - us-east1-a
projects:
  - gcp-prod-gke-100
  - gcp-cicd-101
filters:
  - machineType = n1-standard-1
  - scheduling.automaticRestart = true AND machineType = n1-standard-1
service_account_file: /tmp/service_account.json
auth_kind: serviceaccount
scopes:
 - 'https://www.googleapis.com/auth/cloud-platform'
 - 'https://www.googleapis.com/auth/compute.readonly'
keyed_groups:
  # Create groups from GCE labels
  - prefix: gcp
    key: labels
hostnames:
  # List host by name instead of the default public ip
  - name
compose:
  # Set an inventory parameter to use the Public IP address to connect to the host
  # For Private ip use "networkInterfaces[0].networkIP"
  ansible_host: networkInterfaces[0].accessConfigs[0].natIP

Hint

If you notice any issues in this documentation, you can edit this document to improve it.


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.
