Abstract:
Presented herein are techniques for monitoring packets in a container networking environment. A method includes receiving a packet at a network node, the packet having been routed to the network node in accordance with instructions from a container orchestration system, inserting an additional field in the packet that is configured to record a path of the packet within a first POD of the host device that includes at least one container, forwarding the packet to the first POD of the host device in accordance with the instructions from the container orchestration system, updating the additional field with container networking path information as the packet transits the first POD and the at least one container therein, storing the container path information in an analytics node of the network node, removing the additional field from the packet, and transmitting the packet from the network node to the network.
