Abstract: A container orchestration platform manages a plurality of instances of resources including a first custom resource and a second custom resource. An API server of the container orchestration platform receives a request to delete an instance of the second custom resource; determines whether instance data associated with the instance of the second custom resource has a backreference identifying an instance of the first custom resource, the backreference indicating the instance of the first custom resource is dependent on the instance of the second custom resource; and in response to determining that the instance data has the backreference to the instance of the first custom resource, bypasses deletion of the instance of the second custom resource.

Abstract: Techniques are described for capturing dropped packets and creating modified dropped packets with drop information associated with the dropped packets to provide greater details of the dropped packets for further analysis and/or serviceability. For example, a computing device comprises an internal communication channel, a process executing in user space, and a virtual router. The virtual router comprises, for example, processing circuitry and a drop interface to the internal communication channel, wherein the virtual router is configured to: receive a packet; in response to determining the packet is to be dropped, creating a modified dropped packet to include drop information associated with the packet; and provide the modified dropped packet to the drop interface to communicate the modified dropped packet via the internal communication channel to the process.

Abstract: In general, techniques are described for dynamically load balancing among processing cores that a virtual router of a computing device uses to process network traffic associated with different workloads executing on the computing device. In some examples, a first computing device may assign, based on one or more metrics that indicate processing cores utilization or that indicate network traffic processing requirements for a workload that is to execute on a second computing device, network traffic processing for the workload to a first processing core of a plurality of processing cores of the second computing device. A virtual router, executing on the first processing core based on the assigning, may process network traffic for the workload.

Abstract: Techniques are disclosed for a network device to preserve packet flow information across bump-in-the-wire (BITW) firewalls. For example, a method comprises receiving, by a network device, a packet. The method also comprises determining, by the network device, that the packet matches a packet flow that is associated with an action to redirect the packet to a firewall configured as a bump-in-the-wire. The method further comprises, in response to the determination: modifying, by the network device, a Media Access Control (MAC) address field of a layer 2 (L2) packet header with a flow identifier of the packet flow; sending, by the network device, the packet to the firewall; receiving, by the network device, the packet from the firewall; and recovering, by the network device, the packet flow by modifying the packet according to the flow identifier in the packet to restore the L2 packet header of the packet.
