Multiple clusters managed by software-defined network (SDN) controller

A method comprising:

• receiving an indication of a first cluster identifier for a first cluster of computing devices, wherein the first cluster is implemented using a first orchestrator controller of a container orchestration system, the first orchestrator controller configured to establish a first group of workloads for the first cluster;
• receiving an indication of a second cluster identifier for a second cluster of computing devices, wherein the second cluster is implemented using a second orchestrator controller of the container orchestration system that is different from the first orchestrator controller, the second orchestrator controller configured to establish a second group of workloads for the second cluster;
• in response to determining that first configuration information indicates the first cluster identifier, configuring a first set of virtual routers at the first cluster to connect the first group of workloads to a network using the first configuration information;
• in response to determining that the first configuration information does not indicate the second cluster identifier, refraining from configuring a second set of virtual routers at the second cluster to connect the second group of workloads to the network using the first configuration information;
• in response to determining that second configuration information indicates the second cluster identifier, configuring the second set of virtual routers at the second cluster to connect the second group of workloads to the network using the second configuration information;
• and
• in response to determining that the second configuration information does not indicate the first cluster identifier, refraining from configuring the first set of virtual routers at the first cluster to connect the first group of workloads to the network using the second configuration information.

A non-transitory computer-readable storage medium storing instructions thereon that when executed cause one or more processors, via execution of a single software-defined networking (SDN) controller, to:

• receive an indication of a first cluster identifier for a first cluster of computing devices, wherein the first cluster is implemented using a first orchestrator controller of a container orchestration system, the first orchestrator controller configured to establish a first group of workloads for the first cluster;
• receive an indication of a second cluster identifier for a second cluster of computing devices, wherein the second cluster is implemented using a second orchestrator controller of the container orchestration system that is different from the first orchestrator controller, the second orchestrator controller configured to establish a second group of workloads for the second cluster;
• in response to a determination that first configuration information indicates the first cluster identifier, configure a first set of virtual routers at the first cluster to connect the first group of workloads to a network using the first configuration information;
• in response to a determination that the first configuration information does not indicate the second cluster identifier, refrain from configuring a second set of virtual routers at the second cluster to connect the second group of workloads to the network using the first configuration information;
• in response to a determination that second configuration information indicates the second cluster identifier, configure the second set of virtual routers at the second cluster to connect the second group of workloads to the network using the second configuration information;
• and
• in response to a determination that the second configuration information does not indicate the first cluster identifier, refrain from configuring the first set of virtual routers at the first cluster to connect the first group of workloads to the network using the second configuration information.
