You should not do this directly in this file. Please transfer your changes to the autogen/cluster_regional.tf template. The same is related to all changes that are connected to the resources that are present in autogen folder. The changes from this folder are propagated to all places where they are used.

Your lint tests failed because you should have executed 2 commands before commit:
make generate
make generate_docs

[alexkonkin]

Please also don't forget to add the tests that validate that your feature is present in the newly created cluster.

@alexkonkin Thank you!

Fixed, I've added appropriate variables to autogen

Please apply the suggested changes, run make generate && make generate_docs, and then commit the changes.

Quoting the results of the integration-tests execution:
a)
google_compute_subnetwork.main: Error waiting to create Subnetwork: Error waiting for Creating Subnetwork: Quota 'ROUTES' exceeded. Limit: 250.0 globally.
b)
Error waiting for Deleting Network: The network resource '<...>/networks/cft-gke-test-5pwt' is already being used by <...>/regions/us-east4/subnetworks/cft-gke-test-5pwt'

It seems that some resources have not been deleted after the previous CI execution....
As far as I remember such situation can be resolved by the one who has
the administrator's permission to do this.

I manually verified the node pool suite; the failure is unrelated to these changes.
