Required. The parent, which owns this collection of deployment groups. Format: 'projects/{project_id}/locations/{location}'.

Optional. Lists the DeploymentGroups that match the filter expression. A filter expression filters the deployment groups listed in the response. The expression must be of the form '{field} {operator} {value}' where operators: '<', '>', '<=', '>=', '!=', '=', ':' are supported (colon ':' represents a HAS operator which is roughly synonymous with equality). {field} can refer to a proto or JSON field, or a synthetic field. Field names can be camelCase or snake_case. Examples: - Filter by name: name = "projects/foo/locations/us-central1/deploymentGroups/bar" - Filter by labels: - Resources that have a key called 'foo' labels.foo:* - Resources that have a key called 'foo' whose value is 'bar' labels.foo = bar - Filter by state: - DeploymentGroups in CREATING state. state=CREATING

Optional. Field to use to sort the list.

Optional. When requesting a page of resources, 'page_size' specifies number of resources to return. If unspecified, at most 500 will be returned. The maximum value is 1000.

Optional. Token returned by previous call to 'ListDeploymentGroups' which specifies the position in the list from where to continue listing the deployment groups.
