Introduction

Mizu (water in Japanese) is a relatively new tool that is making some waves in the Kubernetes universe. It was open sourced by UP9 and it claims the following:

Which is a very bold claim!

Lets deep dive a little into the tool and see if it stacks up to all it promises.

Mizu — the new wireshark?

CLI

Let’s start by fetching the tool.

The CLI is completely standalone, easily downloadable and is compiled for all major OS & arquitectures (Linux, Windows, Apple Intel & Apple M1).

For Linux its a simple as:
