We were using netcat to port to check if a service is up, but actually
we can do like Docker / Podman compose and check the status. For now,
I'm using the endpoint status, but maybe we can just check if the object
is "up".
Common mistake...
- Docker and Podman uses "command" as argument to "entrypoint"
- Kubernetes uses "command" as entrypoint and "args" as argument
So, we needed to use Command and Args in all related objects.
Fixes#163
