Set
master_ipv4_cidr_block
tonull
whenprivate_endpoint_subnetwork
is set, as the two conflict with an API level error being thrown:Error: googleapi: Error 400: When masterIpv4Cidr is set, privateEndpointSubnetwork must be unset.
Fixes #2119
This would have the effect of silently ignoring the setting even when
master_ipv4_cidr_block
is explicitly set. A better fix might be to throw an error, but given that there's a baked in default and that terraform module validation can't look at the values of other variables, I don't think that would be trivial.
