Networks for a System with Controller Storage¶
For a system that uses controller storage, StarlingX recommends an intermediate network configuration.
StarlingX systems with controller storage use controller and worker hosts only. Network loading is low to moderate, depending on the number of worker hosts and containers. 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 the cluster, by default consolidated on the management interface.
The cluster host network can also be used for external connectivity of container workloads, in which case it 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 other configured ports on both the controller and worker nodes are used for container workloads connectivity to external networks.
A PXE Boot server to support controller-0 initialization.
You can enable secure HTTPS connectivity on the OAM network.
