Confluent profiles initialized as of 3.3 or later contain the confignet network configuration facility. It is invoked in the default firstboot sections of scripted install profiles and onboot sections of diskless profiles.

Specifiying multiple network interface configuration

The net.* attributes may be qualified by name. For example, it’s possible to specify net.management.ipv4_address=172.16.0.{n1}/16 and net.compute.ipv4_address=172.17.0.{n1}/16. The name between net and the specific attribute is up to the user and has no particular meaning to confluent apart from the name being used to group settings together.

Configuring additional interfaces with autosense

If a confluent deployment server is configured for a given subnet, the deploying server will autosense the correct IP subnet and match the group automatically.

net.deployment.ipv4_address=1.2.3.4/16

Configuring additional interfacces manually

If autosense is not feasible or not desired, specifiy net.name.interface_names to indicate the interface to use with this network configuration. For example:

net.infiniband.interface_names=ib0
net.infiniband.ipv4_address=1.2.3.4/16

Configuring a network interface team

confignet supports configuring teams by specifiying the team mode by, for example, net.compute.team_mode=lacp. If the team members are on the same subnet as a confluent deployment servers, the members may be autodetected. If the member interfaces do not share a subnet with a confluent server, then the names must be explicitly specified in net.*.interface_names, e.g. ib0,ib1.

Example of a team that shares a network segment with a confluent server:

net.example.team_mode=lacp
net.example.ipv4_address=1.2.3.4/16

Example of a team that does not share a network with a confluent server:

net.example.team_mode=lacp
net.example.ipv4_address=4.3.2.1/16
net.example.interface_names=eno1,eno2
