CAF inside a container

[Gerry Meyer]

Is there anything to be said against the idea of using CAF in a Docker container, provided that several cores per container have been configured?

The current trend is towards containers and powerful tools to orchestrate those (Kubernetes).

What I like about CAF is the good use of available cores and the natural decoupling of tasks running in parallel.

It might be possible to establish a communication channel, by using CAF's streaming feature, between the pods running in different nodes.

 

Would it make sense to use both worlds in parallel or is there a principle or implementation details that would make this approach impossible or useless?

Conceptually, putting CAF applications into containers is perfectly fine. The nodes only need TCP to speak to each other.

There’s one catch at the moment: you might get some weird behavior when restarting your containers as of 0.17.3. See https://github.com/actor-framework/actor-framework/pull/970 (maybe a good idea to cherry-pick that patch).

Hope that helps.
