issue with running inventory with gcp_compute plugin filters

[zach....@multiscalehn.com]

I'm trying to get a list of Ubuntu instances from a GCE project. This is what my inventory file looks like.

plugin: gcp_compute

projects:

 - <project-name>

filters:

  - disks.licenses:ubuntu

auth_kind: serviceaccount

service_account_file: ~/google_cloud/service_account/key/<filename>.json

I have referred to this page for the gcp_compute plugin: https://docs.ansible.com/ansible/latest/plugins/inventory/gcp_compute.html

And when it refers to filters, the documentation links to this page: https://cloud.google.com/compute/docs/reference/rest/v1/instances/list

When I run:

gcloud compute instances list --filter="(disks.licenses:ubuntu)" --format=json

... it works just fine and only returns Ubuntu instances.

However, running

ansible-inventory -i <filename>.gcp.yml --list

... with the "disks.licenses:ubuntu:" filter returns the following:

[WARNING]:  * Failed to parse /Users/username/.ansible/inventory/<filename>.gcp.yml with yaml plugin: Plugin configuration YAML file, not YAML inventory

[WARNING]:  * Failed to parse /Users/username/.ansible/inventory/<filename>.gcp.yml with ini plugin:

[WARNING]:  * Failed to parse /Users/username/.ansible/inventory/<filename>.gcp.yml with auto plugin: [{'domain': 'global', 'reason': 'invalid',

'message': "Invalid value for field 'filter': 'disks.licenses:ubuntu'. Invalid list filter expression."}]

[WARNING]: Unable to parse /Users/username/.ansible/inventory/<filename>.gcp.yml as an inventory source

[WARNING]: No inventory was parsed, only implicit localhost is available

{

   "_meta": {

       "hostvars": {}

   },

   "all": {

       "children": [

           "ungrouped"

       ]

   },

   "ungrouped": {}

}

Has anyone been able to resolve this sort of issue before? If so, what did you do?

Reading https://cloud.google.com/compute/docs/reference/rest/v1/instances/list

It seems `filters` should look like:

`scheduling.automaticRestart = false`

So I think you want:

```

filters: 

  - disks.licenses = ubuntu

```

There are examples on the gcp_compute inventory plugin page at: https://docs.ansible.com/ansible/latest/plugins/inventory/gcp_compute.html#examples

Matt,

Thank you for the reply. I failed to mention what I've tried before.

So, I tried what you suggested and I got more or less the same error message. I've also tried the following:

 

disks[].licenses[]:ubuntu

disks.licenses=ubuntu

disks[].licenses[]=ubuntu

 

I've also referred to their examples page before but it seems insufficient for comparing arrays of data. Another interesting thing (that may or may not be worth noting) is that when I run my inventory file and try to use machineType as a filter, it actually filters off of `machineType_selflink` instead.
