Red Hat build of MicroShift

Configure the advertise address network flag

The apiserver.advertiseAddress flag specifies the IP address on which to advertise the API server to members of the node. This address must be reachable by the node. You can set a custom IP address here, but you must also add the IP address to a host interface. Customizing this parameter preempts MicroShift from adding a default IP address to the br-ex network interface.

If you customize the advertiseAddress IP address, make sure it is reachable by the node when MicroShift starts by adding the IP address to a host interface.

If unset, the default value is set to the next immediate subnet after the service network. For example, when the service network is 10.43.0.0/16, the advertiseAddress is set to 10.44.0.0/32.
