Network reconfiguration for cluster

An apparatus, comprising:

• one or more memories;
• and
• one or more processors, wherein the one or more memories store code comprising instructions executable, individually or collectively, by the one or more processors to cause the apparatus to:
• receive, at a cluster comprising a plurality of nodes, a new network configuration for the cluster, wherein respective nodes of the plurality of nodes have respective routable network addresses in accordance with an existing network configuration of the cluster, and wherein the new network configuration is configured to change the respective routable network addresses of the respective nodes relative to the existing network configuration;
• identify, based at least in part on receiving the new network configuration, a driving network interface between the existing network configuration and the new network configuration;
• determine, based at least in part on identifying the driving network interface, that the respective nodes are communicatively coupled over the driving network interface using respective local network addresses of the respective nodes;
• and
• execute, based at least in part on the respective nodes being communicatively coupled via the driving network interface using the respective local network addresses, a process for configuring the new network configuration at the cluster via the driving network interface.

A non-transitory, computer-readable medium storing code that comprises instructions that are executable, individually or collectively, by one or more processors of a device to cause the device to:

• receive, at a cluster comprising a plurality of nodes, a new network configuration for the cluster, wherein respective nodes of the plurality of nodes have respective routable network addresses in accordance with an existing network configuration of the cluster, and wherein the new network configuration is configured to change the respective routable network addresses of the respective nodes relative to the existing network configuration;
• identify, based at least in part on receiving the new network configuration, a driving network interface between the existing network configuration and the new network configuration;
• determine, based at least in part on identifying the driving network interface, that the respective nodes are communicatively coupled over the driving network interface using respective local network addresses of the respective nodes;
• and
• execute, based at least in part on the respective nodes being communicatively coupled via the driving network interface using the respective local network addresses, a process for configuring the new network configuration at the cluster via the driving network interface.
