The type of credential used. Choices:

Toggle to enable/disable the caching of the inventory’s source data, requires a cache plugin setup to work. Choices:
Configuration:
|
|
Cache connection data or path, read cache plugin documentation for specifics. Configuration:
|
|
Cache plugin to use for the inventory’s source data. Default: “memory” Configuration:

|
Create vars from jinja2 expressions. Default: {} |
|
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) |
|
A folder that contains many projects |
|
Add hosts to group based on Jinja2 conditionals. Default: {} |
|
A list of options that describe the ordering for which hostnames should be assigned. Currently supported hostnames are ‘public_ip’, ‘private_ip’, or ‘name’. Default: [“public_ip”, “private_ip”, “name”] |
|
Add hosts to group based on the values of a variable. Default: [] |
|
The default value when the host variable’s value is an empty string. This option is mutually exclusive with |
|
The key from input dictionary used to generate groups |
|
parent group for keyed group |
|
A keyed group name will start with this prefix Default: “” |
|
separator used to build the keyed group name Default: “_” |
|
Set this option to False to omit the This option is mutually exclusive with Choices:
|
|
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:

|
token that ensures this is a source file for the ‘gcp_compute’ plugin. Choices:
|
|
A list of projects in which to describe GCE instances. |
|
Populate the 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 Choices:
|
|
list of authentication scopes Default: [“https://www.googleapis.com/auth/compute”] Configuration:
|
|
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). Configuration:
|
|
An optional service account email address if machineaccount is selected and the user does not wish to use the default email. Configuration:
|
|
The path of a Service Account JSON file if serviceaccount is selected as type. Configuration:
|
|
If Since it is possible to use facts in the expressions they might not always be available and we ignore those errors by default. Choices:
|
|
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. Choices:
|
|
Merge extra vars into the available variables for composition (highest precedence). Choices:
Configuration:
|
|
prefix to apply to host variables, does not include facts nor params Default: “” |
|
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: google.cloud.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
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.
