machineType

The machine type to create. Note: If you want to update this value (resize the VM) after initial creation, you must set allow_stopping_for_update to true. Custom machine types can be formatted as custom-NUMBER_OF_CPUS-AMOUNT_OF_MEMORY_MB, e.g. custom-6-20480 for 6 vCPU and 20GB of RAM. Because of current API limitations some custom machine types may get converted to different machine types (such as an equivalent standard type) and cause non-empty plans in your configuration. Use lifecycle.ignore_changes on machine_type in these cases. There is a limit of 6.5 GB per CPU unless you add extended memory. You must do this explicitly by adding the suffix -ext, e.g. custom-2-15360-ext for 2 vCPU and 15 GB of memory.
