I'm still a bit of a Docker/container n00b, so please bear with me. I'd like to maintain 3 categories of environments for an application that consists of a:
The 3 categories needed are:
Do the orchestration solutions like Swarm and Kubernetes handle this scenario such that the containers within a category know about the others (e.g. Web3 knows about DB3 and Cache3 but none of the others), and would they be able to easily accommodate adding another trio of containers (Web+DB+Cache) to one of the existing categories (e.g. Internal)?

In Kubernetes this is possible through the use of Namespaces
.
I don't want to get to in-depth if you are like you say a "Kubernetes n00b", but Docker containers are held in Pods
and talk to each through Services
, both of which can be restricted to a specific Namespace
.
So you could have a Pod
called "front-end" that talks to a Pod
called "backend-end" through the "back-end" Service
, this could be deployed three time in three different Namespaces
and each "front-end" Pod
would live in it's Namespace
and talk to it's own "back-end" Pod
through it's own "back-end" Service
all in the same Namespace
.
