My first impression with "Wireshark for Docker containers" is "... Well, Wireshark already works with Docker containers, so if your goal is to be Wireshark for Docker containers, you'll just fail by definition. Can't beat Wireshark at being Wireshark."

I'm saying this just FYI. I haven't actually looked at what your product does, but if it were to matter to me, it'd be based on what it can offer that Wireshark can't, rather than how similar it is to Wireshark.
