Hey Chris - I'm reading over your proposal for the container module and I'm curious if there are any plans to implement something similar to the count parameter from the current docker module?

As the examples in the proposal indicate, you can certainly start and stop multiple containers using _with_items_ or _with_sequence_. The idempotence of the count parameter, however, lets you easily scale the number of containers up or down through a single playbook or host variable.

Having a dedicated module parameter for the container count also means you can use handlers for the change events that are triggered when the number of containers on a host changes unexpectedly between playbook runs.

@jakemcdermott I'm not sure why that is needed since all of that can still be achieved in a with_ loop.

I welcome the addition of sane docker modules! I only looked at the things I tend to need (pulling images, managing container lifecycle) and these look way better! Thank you for cleaning up!

Is there an ETA or some way to help (after the ground work is done)?

As per meeting we are going to accept the proposals, will discuss implementation details on the PRs.
