### OTHER OPTIONAL VARIABLES ### OTHER OPTIONAL VARIABLES
## By default, Kubespray collects nameservers on the host. It then adds the previously collected nameservers in nameserverentries.
## If true, Kubespray does not include host nameservers in nameserverentries in dns_late stage. However, It uses the nameserver to make sure cluster installed safely in dns_early stage.
## Use this option with caution, you may need to define your dns servers. Otherwise, the outbound queries such as www.google.com may fail.
