List Instances
compute_engine.list_instances
ActionGoogle Cloudconnection required
Calls Compute Engine API v1 GET /projects/{p}/zones/{z}/instances.
List Compute Engine VM instances in a zone.
Connection
- Required
- Yes — the node will not save without one
- Auth type
- OAuth 2.0
- Providers
- Google Compute Engine
- Secret shape
- {"client_id", "client_secret", "refresh_token"}
- Config it needs
- project_id, zone
- Resolved by
- config.connection_id, else node.connection_id
Configuration
4 fields, none required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.
| Field | Type | Required | Default | Constraints | Example |
|---|---|---|---|---|---|
project_id GCP project id (overrides connection). | string | No | — | — | — |
zone Zone, e.g. us-central1-a (overrides connection). | string | No | — | — | — |
filter Filter, e.g. status=RUNNING. | string | No | — | — | — |
max_results Max instances to return. | number | No | 100 | ≥ 1 | — |
Example configuration
Every value below is the contract’s own example or default — nothing invented.
{
"max_results": 100
}Output
One shape.

ok | boolean | — |
instances | array | — |
count | number | — |
{
"count": 0,
"instances": [],
"ok": false
}See List Instances run in a workflow.
In a technical demo we add the Google Compute Engine connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
