Add DNS Mapping

If your VMware vSphere environment is configured with Dynamic Host Configuration Protocol (DHCP), you can add a Dynamic Name Server (DNS) mapping to the Private Cloud Gateway (PCG) to resolve the hostnames of the nodes in the PCG. You can also use the DNS mapping ensure nodes are alocated to the correct datacenter, cluster and network.

You can add multiple DNS mappings to a PCG to support different datacenters and networks in your VMware vSphere environment.

Prerequisites​

  • A PCG is installed, active, and in a healthy state. Refer to Deploy a PCG for instructions on how to install a PCG.

  • Access to the VMware vSphere environment.

  • Tenant administrator access.
