1. A method for configuring an egress node for an egress pod set comprising one or more pods, the method comprising:
selecting a node of a cluster of nodes to act as the egress node for the egress pod set, wherein the egress pod set has a single active egress internet protocol (IP) address, wherein the single egress IP address is outside a classless inter-domain routing (CIDR) block of a subnet of the egress node, and wherein selecting the node comprises selecting the node based on a number of egress pod sets associated with the node; and
configuring a router with a static route to associate the egress node with the single active egress IP address.
