Dynamic configuration of a cluster network in a virtualized computing system

A non-transitory computer readable medium comprising instructions to be executed in a computing device to cause the computing device to carry out a method of configuring a cluster network for an application management system having virtual machines (VMs) executing on a virtualization layer in a cluster of hosts connected to a physical network, wherein the application management system is integrated with the virtualization layer and the VMs include first VMs in each of which one or more containers of an application managed by the application management system are to be executed, the method comprising:

• receiving, at a first master server, a request to assign network ports of the cluster network, to which the first VMs are connected, to second VMs of the VMs, the second VMs implementing a control plane of the application management system through which containers of the application are deployed for execution in the first VMs, the control plane of the application management system including the first master server, and the second VMs having first network interfaces connected to a management network isolated from the cluster network;
• provisioning, by cooperation of the first master server with a network manager connected to the management network, the network ports of the cluster network;
• and
• reconfiguring, by cooperation of the first master server with a virtualization management server connected to the management network, the second VMs with second network interfaces connected to the network ports of the cluster network.

A virtualized computing system integrated with an application management system, comprising:

• a host cluster of hosts connected by a physical network and executing a virtualization layer on hardware platforms of the hosts, wherein the hardware platform of each host includes a processor and memory, and the virtualization layer is configured to support execution of virtual machines (VMs) and is integrated with the application management system, the VMs including first VMs in each of which one or more containers of an application managed by the application management system are to be executed and second VMs that implement a control plane of the application management system through which containers of the application are deployed for execution in the first VMs;
• and
• a software-defined (SD) network layer of the host cluster configured to provide a cluster network for the application management system, wherein
• the second VMs have first network interfaces connected to a management network isolated from the cluster network and include a first master server, which is configured to:
• receive a request to assign network ports of the cluster network to the second VMs;
• provision, by cooperation with a network manager connected to the management network, the network ports of the cluster network;
• and
• reconfigure, by cooperation with a virtualization management server connected to the management network, the second VMs with second network interfaces connected to the network ports of the cluster network.
