Google Cloud Platform - How to filter instances.list by tag?

问题

I'm trying to filter list of instances by tag name

What works perfectly with gcloud, e.g.

gcloud compute instances list --filter 'tags.items=firewall-client-mongodb'

Does not work with API, which always returns 400:

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "invalid",
    "message": "Invalid value for field 'filter': 'tags.items = test'. Invalid list filter expression."
   }
  ],
  "code": 400,
  "message": "Invalid value for field 'filter': 'tags.items = test'. Invalid list filter expression."
 }
}

Is there any way to filter instances by tag, or any user defined variable? I'm testing with https://cloud.google.com/compute/docs/reference/rest/v1/instances/list

回答1:

I was able to reproduce the issue and got the same error you got. This seems to be an issue with the API. I would recommend you to Create new Compute Engine issue using this link for issue trackers.

Trying this for myself (today) and your command should now work.

Curiously, it does not appear to work correctly if --zones=... flag is provided. This is additionally challenging (!?) because the underlying API call requires the zone to be provided and so this always fails if a filter is used.

gcloud compute instances list \
--filter="tags.items=${TAG}" \
--project=${PROJECT}
NAME           ZONE        MACHINE_TYPE
my-machine     us-west1-c  f1-micro

gcloud compute instances list \
--project=${PROJECT} \
--zone=us-west1-c
NAME           ZONE        MACHINE_TYPE
my-machine     us-west1-c  f1-micro

gcloud compute instances list \
--filter="tags.items=${TAG}" \
--project=${PROJECT} \
--zones=us-west1-c
ERROR: (gcloud.compute.instances.list) Some requests did not succeed:
 - Invalid value for field 'filter': 'tags.items eq ".*\bfred\b.*"'. Invalid list filter expression.
