You are awesome @Devatoria ! :)

Is there something to improve here ?
I was thinking about moving all functions from chaosk8s/probes.py to differents folders:

• deployment_is_not_fully_available, deployment_is_fully_available, microservice_available_and_healthy, and microservice_is_not_available to deployment/probes.py
• service_endpoint_is_initialized to service/probes.py
• I don't know about all_microservices_healthy

Should I commit directly on @Devatoria repository ?

I think moving things around is a good idea.

Maybe keeping existing modules with the functiin linking to the appropriate ones but with a warning when they are used from there?

Also, the whole business of "microservice" was a stupidity of mine, it's just a top-down deployment to pod set of functions. Should they remain that way?
