%description
A kubectl plugin that utilize tcpdump and Wireshark to start a remote capture on any pod in your Kubernetes cluster.
You get the full power of Wireshark with minimal impact on your running pods.

When working with micro-services, many times it's very helpful to get a capture of the network activity between your micro-service and it's dependencies.
ksniff use kubectl to upload a statically compiled tcpdump binary to your pod and redirecting it's output to your local Wireshark for smooth network debugging experience.
