Wireshark Extension for Docker - Packet Sniffing Between Containers

[suyoggatkal20]

Hi everyone,
I’d like to suggest a Wireshark extension for Docker that enables users to inspect network traffic between containers on a given Docker network. This extension would allow real-time packet capture and analysis directly within the Docker environment, helping developers and security professionals troubleshoot network issues, debug applications, and monitor communications between services.

Why is this useful?

Troubleshooting Network Issues – When working with microservices or containerized applications, network-related problems can be difficult to diagnose. This extension would help visualize traffic flow and pinpoint connectivity issues.
Security and Compliance – Developers and security teams could analyze network traffic for potential vulnerabilities, unauthorized access, or insecure data transmission between containers.
Protocol Debugging – This would be useful for developers working with custom protocols or APIs to inspect request/response interactions in real-time.
Performance Optimization – Analyzing network traffic can help identify bottlenecks and optimize communication between services.

Hey,

just by reading your proposal it's not clear to me whether you already have a way to inspect network traffic and you just want to make it more convenient to use, but in case you don't, you may want to head to Siemens Containershark Extcap Plugin for Wireshark and follow the instructions there. I also need all the things under your "why is this useful" list and it does the job perfectly.
What you basically need to set up is spin up two containers (edgeshark and g(h)ostwire), install Wireshark extension and you're good to go!
