If your interest extends to debugging production backends you can also check out Lightrun ( https://lightrun.com ) which continues this all the way through.
This lets you send action commands to production without having a debug session into you K8S cloud.
So you can add a conditional snapshot (a breakpoint that doesn't break) to the set of green containers. E.g. I can add a snapshot that has a condition to only grab the data for user X. I'll get the result regardless of the container that actually handles the request.
