Network Topology: Dedicated Setup | ||
================================= | ||
|
||
|
||
|
||
Depending on internet access for host nodes, there are two ways to achieve a dedicated NIC setup: | ||

When all cluster nodes have their own public network access, ``primary_dns`` and ``secondary_dns`` in ``provision_config.yml`` become optional variables as the control plane is not required to be a gateway to the network. The network design would follow the below diagram: | ||

When all cluster nodes rely on the control plane for public network access, the variables ``primary_dns`` and ``secondary_dns`` in ``provision_config.yml`` are used to indicate that the control plane is the gateway for all cluster nodes to get internet access. Since all public network traffic will be routed through the control plane, the user may have to take precautions to avoid bottlenecks in such a set-up. | ||
