Expected Behavior

Would have expected 1 node per zone

Actual Behavior

resulted in 0 nodes

@katebrenner below is the comment in the doc for google_container_cluster. Does it make sense?

initial_node_count - (Optional) The number of nodes to create in this cluster's default node pool. In regional or multi-zonal clusters, this is the number of nodes per zone. Must be set if node_pool is not set. If you're using google_container_node_pool objects with no default node pool, you'll need to set this to a value of at least 1, alongside setting remove_default_node_pool to true.

@edwardmedia Thank you! Yes that makes sense for google_container_cluster ! However, this information is missing from the container_node_pool doc in which I was referencing. Could it be added there as well for extra clarity?

[edwardmedia]

@katebrenner it could. Please file a separate issue labelled document for triage. Closing this issue then. Thank you
