Configuring Scale daemon network IP parameters
This is an optional configuration and is only needed when the default scale daemon IPs conflicts with some of your workloads. An additional IPVLAN Container Network Interface (CNI) network named as daemon-network is created for scale core pods. By default, IP addresses are assigned for Scale daemon network. You can override the default IP addresses before you begin the Final installation of IBM Fusion HCI. If the default IPs are being overridden ensure that they are configured in a private subnet.
About this task
Scale core pods have two networks, namely admin and daemon network. Admin network is the default pod network and pod service domain, whereas the daemon network is used for communication between the Scale core pods.
Compute nodes parts of the Scale cluster are annotated to provide the daemon network name, IPv4 address, gateway, and optionally the machine address.
By default, for Scale daemon network, the private IPv4 addresses is in the range of 192.168.128.6 to 192.168.191.254. The default gateway for this network is 192.168.128.1. This default allocated IP range can be overridden if necessary.
