Networks for a Duplex System¶
For a StarlingX Duplex system, StarlingX recommends a minimal network configuration.
StarlingX Duplex uses a small hardware footprint consisting of two hosts, plus a network switch for connectivity. Network loading is typically low. The following network configuration typically meets the requirements of such a system:
An internal management network
An OAM network, optionally consolidated on the management interface.
A cluster host network for private container-to-container networking within a cluster. By default, this is consolidated on the management interface.
The cluster host network can also be used for external connectivity of container workloads. In this case, the cluster host network would be configured on an interface separate from the internal management interface.
If a cluster host network is not used for external connectivity of container workloads, then either the OAM port or additionally configured ports on both the controller and worker nodes are used for the container workloads connectivity to external networks.
You can enable secure HTTPS connectivity on the OAM network.
