Mapping VLAN of container network to logical network in hypervisor to support flexible IPAM and routing container traffic

A non-transitory machine readable medium storing a program for execution by a set of processing units, the program for adding routable subnets to a logical network that connects a plurality of machines and is implemented by a software defined network (SDN), the program comprising sets of instructions for:

• receiving an intent-based API comprising a request to add a routable subnet to the logical network;
• defining (i) a VLAN (virtual local area network) tag associated with the routable subnet, (ii) a first identifier associated with a first logical switch to which at least a first machine in the plurality of machines that executes a set of containers belonging to the routable subnet attaches, and (iii) a second identifier associated with a second logical switch designated for the routable subnet;
• generating an API call that maps the VLAN tag and the first identifier to the second identifier;
• and
• providing the API call to a management and control cluster of the SDN to direct the management and control cluster to implement the routable subnet;
• wherein the first machine is configured to execute the set of containers, and the routable subnet enables a plurality of containers belonging to the routable subnet to be deployed across the plurality of machines connected by the logical network.
