Abstract: Some embodiments of the invention provide a method for deploying network elements for a set of machines in a set of one or more datacenters. The datacenter set is part of one availability zone in some embodiments. The method receives intent-based API (Application Programming Interface) requests, and parses these API requests to identify a set of network elements to connect and/or perform services for the set of machines. In some embodiments, the API is a hierarchical document that can specify multiple different compute and/or network elements at different levels of compute and/or network element hierarchy. The method performs automated processes to define a virtual private cloud (VPC) to connect the set of machines to a logical network that segregates the set of machines from other machines in the datacenter set. In some embodiments, the set of machines include virtual machines and containers, the VPC is defined with a supervisor cluster namespace, and the API requests are provided as YAML files.

Abstract: In an embodiment, a computer-implemented method for dynamically exchanging runtime state data between datacenters using a controller bridge is disclosed. In an embodiment, the method comprises: requesting, and receiving, one or more first runtime state data from one or more logical sharding central control planes (“CCPs”) controlling one or more logical sharding hosts; requesting, and receiving, one or more second runtime state data from one or more physical sharding CCPs controlling one or more physical sharding hosts; aggregating, to aggregated runtime state data, the one or more first runtime state data and the one or more second runtime state data; determining updated runtime state data based on the aggregated runtime state data, the one or more first runtime state data, and the one or more second runtime state data; and transmitting the updated runtime state data to the logical sharding CCPs and physical sharding CCPs.

Abstract: Some embodiments provide a method for assigning different service path identifiers to each of a set of different service paths along each of which a same set of service operations are performed on a set of packets. The method retrieves an available service path identifier from an identifier storage that stores service path identifiers for multiple service paths. The method generates a set of proposed service path identifiers based on the retrieved available service path identifier and the number of service paths in the set of service paths. The method performs a write operation on the identifier storage based on the set of proposed service path identifiers, and based on a determination that the write operation was successful, assigns the set of proposed service path identifiers to the set of service paths. Based on the set of service path identifiers, the method forwards the set of packets along the set of service paths.

Abstract: Some embodiments provide a method for a first host machine that hosts a virtual machine connected to a particular logical network. The method receives a command to test connectivity between the first host machine and a set of at least one additional host machine that also host virtual machines on the particular logical network. At the first host machine, the method generates a packet for sending to the set of additional host machines in order to test the connectivity. The method appends to the generated packet (i) information that identifies the particular logical network and (ii) a flag indicating that the packet is for connectivity testing. The method encapsulates the generated packet with tunnel endpoint addresses, including a tunnel endpoint located at the first host machine. The method sends the encapsulated packet from the first host machine to the set of additional host machines according to the tunnel encapsulation.

Abstract: Systems and methods for configuring an egress node for an egress pod set comprising one or more pods are provided. The egress pod set may be allocated one or more egress internet protocol (IP) addresses. The egress node may be selected among nodes of a cluster including the one or more pods. The egress node may be configured as the routing destination for an egress IP address selected among the one or more egress internet protocol (IP) addresses.

Abstract: Some embodiments provide an automated method for defining externally routable Pods within a Kubernetes cluster. In some embodiments, the Pod operates in a guest cluster has its own VPC (virtual private cloud) network in a datacenter with several other guest clusters that have their own VPC networks and their own set of managers. In some embodiments, a Pod within a GC can be made externally routable so that it can be directly addressable from an external client outside of the Pod's network by using two new Kubernetes CRDs (custom resource definitions), which are an IPPool CRD and a RouteSet CRD. Examples of such external clients include VMs or Pods in another GC or a supervisor cluster connected to the particular GC through a gateway, or from a machine outside of the network of all of the GCs or SC.

Abstract: A system and method for capturing resource usage information in a network for namespaces in which pods operate are described herein. A data structure specifies a topology that includes a gateway and routing addresses in a network whose usage is to be captured. The data structure is provided to an API of a master node controlling the pods. A controller in the master node enforces the data structure and reports results back to the API.

Abstract: Described herein are systems, methods, and software to manage multicast communications for containers in a computing network. In one example, a first node is configured to monitor for registration packets from pods on the first node to join a multicast group. The first node further identifies a registration packet from a first pod of the pods, wherein the registration packet indicates a multicast IP address, and configures one or more forwarding rules in a virtual switch to direct packets with the multicast IP address as a destination IP address to a virtual interface for the first pod. Once configured, the first node is further configured to receive a packet with the multicast IP address as the destination and direct the packet based on the one or more or more forwarding rules.

Abstract: Some embodiments provide a novel method for processing control plane messages regarding migration of a particular machine from a first host computer managed by a first central control plane (CCP) server to a second host computer. At the first CCP server, the method receives a first data message from the first host computer notifying that the particular machine has been removed from the first host computer. The method determines whether a second data message from a second host computer notifying that the particular machine has been added to the second host computer has been received and processed in order to process the first data message. When it is determined that the second data message has been received and processed, the method processes the first data message.
