Clustering karaf, do I need to use cellar or can I use kubernetes?

[Dana Shaw <ds...@medata.com>]

Was going thru the documentation and some web searches.. 

From the documentation it loos like cellar is preferred for clustering.

My question is, can I use kubernetes instead?

I found a few blog posts on folk setting up Karaf with kubernetes, and would prefer to use a single platform for scaling.

Thanks in advance,

I'm new to Karaf, been playing around with a single instance in docker, was looking on how to scale up from here.

Appreciate the response!

I'm currently using karaf with apache camel and Spring/osgi apps.

I think where I was getting confused is that I saw a kubernetes cluster using cellar.. which in my head didn't make a lot of sense.

Think I'm going to play with clustering karaf with cellar, and deploying karaf with kubernetes and see which one is easier to manage.

Hi,

I'm joining JB, it's depend how you want to scale your Karaf instance, 
if you don't need hot configuration reloading or dynamic feature 
deployment synchronization you can use only K8S.

Hi,

Actually, you can use both.

Cellar brings synchronize of Karaf running instances (live, without
restarting the instances), whereas K8S can orchestrate the startup of
the Karaf instances.
