Tips and tricks

Troubleshoot network traffic of a container

In Kubernetes, each shares its network layer with other containers in the same pod. You can install a container with tcpdump in the same pod, and then use oc rsh to connect to the container and monitor the traffic.

See Using sidecars to analyze and debug network traffic in OpenShift for more details.
